Hello John,

I have struggled with this value, and mixed it up with the connectionTimeout
also.  As a result, when I think there will be a delay, I also set it to
zero, and then I sleep easy.  I did that two years ago with
out troublesome app, and now it works and works and works.  Whats the
downside of infinite timeout.  If it takes three weeks, you will find out
anyway, but why kill it after ten mins when it would have finished
successfully in 19.45 minutes.

I hear you!

BTW how do you kill an executing stored procedure?

Hello John,

Not sure, but stopping the server is one way.  My main problems were sprocs
stopping when I did not want them to stop, for me, if it is still running
after 24 hours, it is probably never going to stop.  For you, you might
increase that to 48 hours, but in general, they either finish promptly, or
else will never finish, either way, timing out after 10, 20, 50, or even 600
minutes is almost never a good option, if there is a possibility that it
will finish in 601 minutes.

There is probably a way to stop a process, Francisco or some of the other
experts may know how, but I would either stop the db server / service, or
else in worst case, do a quick reboot.  For the rest of the year, I would
never worry about it, happy in the knowledge they the server must work till
the death :)

Thanks

Mark

Mark,

 >but I would either stop the db server / service, or else in worst case, do a quick reboot.

I have done both.  I have corrupted the database doing the reboot.  Stopping the service seems to 
work, however I have also seen the database pick up where it left off when the service restarted.

I am sure there is some way to "officially" stop a running process, I just don't know how.

Subject: [dba-VB] C# - Records Affected
Message-ID: <4B153F3A.8010102@colbyconsulting.com>

I am trying to get a count of records appended, updated etc in my SPs and returning that to my C# 
supervisor.  I am finding references to @@Rowcount however this is returning 1 instead of the actual 
number.

Is this @@RowCount the real deal?

The SP definition:

ALTER PROCEDURE [dbo].[sp_AZOut_AZExportToOrderedChunk]
	-- Add the parameters for the stored procedure here
	@DBName varchar(50),
	@ErrorDesc varchar(4000) output,
	@ErrorNo int output,
	@RecsAffected int output

AS
BEGIN


Setting the returned value

	EXEC (@SQL)
	select @RecsAffected = @@RowCount

My c# code:

intRecsAffected = sCmd.Parameters["@RecsAffected"].Value

The code triggers the try block if there is no such parameter (I just ignore it) or returns 1 if the 
parameter exists.

This is a functioning tested SP which typically appends millions of records, though the exact number 
depends on the database.

Is there something I need to know here?

<quote>
Do a select * from sysprocesses and identify the spid in question. Then do a "KILL 
<spidno>"

This will mark the spid as "dead". Note that it may take a while for the process to end as it 
has to rollback all the updates that it has been doing. Also kill only marks the process as 
dead - the process itself needs to check for this, and if it is stuck in a loop as the result of a 
bug or whateverthen it won't terminate. Also certain processes like dump and dbcc 
commands have significant code paths where the kill command is not checked for and so 
these can take some time to terminate.

Also, if the process is in an extended-stored procedure, or is waiting on network 
traffic/remote stored-procedure it will not check whether it has been terminated until these 
actions have been completed.

See Q171224 for more info - including details on the waittype that can tell you what a 
process is waiting on.

If the process won't die for one of the above reasons then your only choice is to stop the 
sqlservr.exe process itself and re-start.

Sorry for the ring, I found the problem.

The SP that I took this code from actually worked but the code I was testing did not and came before 
this code.  The problem was simply that in the SP I did not place the line that captured @@RowCount 
immediately after the EXEC (@SQL) statement.

All of the examples clearly warned me that this was a requirement but you understand "senior moments".

Anyway, this is now working.

Piece by piece this thing is coming together.

As previously mentioned, over the last couple of years I have built up a set of stored procedures 
which perform TSQL.  I then run sets of these stored procedures to perform processes.  The TSQL is 
always dynamic.

As an example a stored procedure might build a table, with boilerplate field names and data types, 
but a passed in database and table name.  Inside of the stored procedure I build up the correct SQL 
to create the table in the database specified, with the name specified.  Another stored procedure 
might create in index, with boilerplate field names, but a passed in database and table name.  Again 
the stored procedure builds up the TSQL statement to create the index in the correct db and table.

I already have these stored procedures debugged and working and have been using them in sets to 
perform "big picture processes" for quite some time, but the whole "execute a stored procedure" 
using a command object, parameter objects in a parameter array, interpreting the parameters etc just 
seems so... 1950s.  I feel like I am flipping switches on the front panel of a computer in a 50s 
sci-fi movie as a tape reel spins madly in the background.

Now that I am moving to C# I am wondering if this is required any more.  Can C# execute TSQL 
directly somehow?  Can I assemble this boiler plate plus database / table kind of thing into a TSQL 
statement directly in C# and then somehow tell SQL Server to execute that TSQL?  I understand the 
"SQL optimization" thing but it seems like (not sure here) that because the TSQL is dynamically 
constructed in the stored procedure, the whole "optimization" thing goes right out the window.  If I 
can execute TSQL directly from C#, what can I get back?  Rows affected?  Error codes?  And how?

As it stands I am happily flipping switches, tape reels whirring, exporting data for address 
validation.  This is good, I am happy, but ...

Hi John --

I must say I have never done that "dynamic" t-SQL via C# - I guess it should
be doable: using SMO or even SqlCommand's .ExecuteNonQuery(?) it should be
possible to create SPs and UDFs, and then execute them as usual...

BTW, UDFs, which return tables are very often a good substitute for all
kinds of temp tables and dynamic SQL...

I wonder what for all that "dynamism" there? 
Do you have constantly changing database structure?
Do you have constantly changing customer requests, which do not allow you to
create a set of stable parameterized SPs and UDFs, and for small(?) changing
part of queries use LINQ for SQL or ADO.NET EF?

Thank you.

Subject: [dba-VB] C# - Direct data manipulation
Message-ID: <sb162315.044@cactus.dk>

Hi John

As I see it, that would be LINQ and ADO.NET EF (Entity Framework). Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you. Critics tell that this SQL could be long-winded (= not optimized) but what do I care? If it flips 17 or 87 switches does nothing to me as long as the result is fast and precise.

ADO.NET EF is an amazing piece of work. It is not mature but if MS continues to evolve it with the same speed as Silverlight I'm sure it will catch up.

As previously mentioned, over the last couple of years I have built up a set of stored procedures 
which perform TSQL.  I then run sets of these stored procedures to perform processes.  The TSQL is 
always dynamic.

As an example a stored procedure might build a table, with boilerplate field names and data types, 
but a passed in database and table name.  Inside of the stored procedure I build up the correct SQL 
to create the table in the database specified, with the name specified.  Another stored procedure 
might create in index, with boilerplate field names, but a passed in database and table name.  Again 
the stored procedure builds up the TSQL statement to create the index in the correct db and table.

I already have these stored procedures debugged and working and have been using them in sets to 
perform "big picture processes" for quite some time, but the whole "execute a stored procedure" 
using a command object, parameter objects in a parameter array, interpreting the parameters etc just 
seems so... 1950s.  I feel like I am flipping switches on the front panel of a computer in a 50s 
sci-fi movie as a tape reel spins madly in the background.

Now that I am moving to C# I am wondering if this is required any more.  Can C# execute TSQL 
directly somehow?  Can I assemble this boiler plate plus database / table kind of thing into a TSQL 
statement directly in C# and then somehow tell SQL Server to execute that TSQL?  I understand the 
"SQL optimization" thing but it seems like (not sure here) that because the TSQL is dynamically 
constructed in the stored procedure, the whole "optimization" thing goes right out the window.  If I 
can execute TSQL directly from C#, what can I get back?  Rows affected?  Error codes?  And how?

As it stands I am happily flipping switches, tape reels whirring, exporting data for address 
validation.  This is good, I am happy, but ...

Message-ID: <c7fd28d00912020223q1c3e0388sec97ee600fd01dd2@mail.gmail.com>

Hello All,

I am running VS 2008 on a powerful machine with loads of resources.  My
project is a DNN project sitting in the wwwroot folder which allows me to
change a few lines of code and then immediately see the results in the web
app.

However, when I manipulate the Data Context Objects in the AppCode Folder,
the response times are dreadfully, slow.  It takes three to four minutes to
open, edit, save and close one of these objects.

I have tried it on a second machine and the results are similar.

I can edit the Dbml files outside of the solution, but I am not sure whether
that is safe to do so, when I edit them outside the solution (copying and
pasting to another folder and then opening the dbml file from there), they
open instantly.  When I say "safe to do so", does the project file or the
sln file need to be updated with the changes that have been made.  I do get
some warning message about "cannot find web.config, so using the file from
the dbml file instead" which I accepted.

I recall Shamil mentioned that manually editing these within the individual
files is not a good idea, so i guess that he may have been suffering the
same problems as I am, IE so sloooow to open and close.

TIA for an help, if I have not expressed the problem clearly enough, let me
know,

Mark

Hello Mark --

First of all try to switch to FireFox - forget IE while debugging large
ASP.NET apps from within VS....

I  can only note that debugging large ASP.NET applications is a real PITA -
this is why I'm always trying to get out as much as possible BL and DAL code
into separate projects and develop, debug/test them without UI (ASP.NET or
WinForms or WCF)...

And DNN is a "huge ASP.NET" app with a lot of classlibs, which are so
tightly coupled together that there is no way to debug part of them outside
of running DNN instance - with all the consequences - bad luck...

I suppose you can edit DNN's Data Context Objects source code from AppCode
outside of VS (e.g. within notepad) - when the edits are saved then DNN will
restart, that could take a while, quite a while....

A temp solution could be to keep *all* the source code of DNN module's
control within that control's code behind .aspx.cs (.aspx.vb) during
development - when you edit your code there then ASP.NET app will not
restart it will just recompile .aspx and .aspx.cs - so it should work
considerably quicker...

All in all I think DNN custom modules development is a RPITA - one can never
know how much it will finally take for a given project if they will not try
to find a way to debug/ test as much as possible code outside of running
DNN: something like develop a separate ASP.NET application, make it working
and then port it to DNN environmnet...

Be prepared for "crazy debug sessions" (if I'm  not missing something and
there are some "miracle" tools, which simplify DNN custom development
debugging)...

Philosophic note: DNN seems to be a good example that there "are no miracles
in this world" - DNN is a great prototyping tool and CMS, when one has ready
to use DNN modules and skins, and DNN is becoming RPITA when one have to
develop a(n) (advanced) custom module. Rhetoric Question: Why in this world
there couldn't be a "silver-bullet" tool able to support both standard and
custom development with the same ease as DNN does support CMS development?

I guess "Ruby on Rails" could be "what doctor ordered"?...

Or ASP.NET MVC2 Framework?

DNN did grow from a "junky" MS ASP.NET sample code base, and even advanced
developers as DNN Core Development Team members are can't still "convert"
that original "junk" to pearls...

Hopefully they will do that in DNN v.7? - they "just" need to clean-up DNN
huge code base and to implement what is called "Inversion of Control"
(http://martinfowler.com/articles/injection.html) to "untight" DNN Core
classlibs as much as possible...

Please correct me if I'm wrong - in fact I'd be really happy to be wrong
here as I have had to suspend one of the DNN projects, which didn't go
smoothly because of PITA DNN custom modules development experience...

Sorry, Mark, I have no a definitive answer for you here - just some "soap"
and "bubbles" and PITA of my own DNN custom modules development experience,
which I need to find a way to workaround, or quit the idea of DNN custom
development completely as it's too expensive to be true. Still hope I missed
some approaches to simplify this development - I mean ready to use
approaches and tools without long learning curve...

Thank you.

Hello Shamil,

Thank you for your detailed response.

*Browsers*
Some comments, I am actually using Chrome to View my work, but I am not
doing any debugging, in the traditional sense, I code a few lines, click
save and then view the results in Chrome, when I am not happy, I flick back
to VS, change it and continue again.  So, it is true to say, I am not really
debugging, just viewing.  However, I stopped using IE a few years ago, and
since I switched to Chrome, it is the first thing I install on new machines.
 With the exception of the MSDN site, it works perfect for me.


*Slow Data Contexts*
So can I assume that this slowness is simply to be accepted, it is either a)
the way VS2008 usually performs, or b) the way VS2008 performs when data
contexts are involved in a large project such as DNN.  I did not notice any
difference when I copied the code from the wwwroot folder, so I hope that is
not part of the problem.

*DNN Development*
Probably I am not doing real DNN custom programming, but I am currently
building web user controls, and simply saving them, and then creating a
module for DNN and including the web user control on that module.  I know
this is not real DNN programming, but have created about 20 module so far
like this.  DNN gives me, as a script kiddie type programmer, they ability
to do a simple web app, but it manages the users and authentication,
something that I could never program.

IOW, with the exception of a few DNN hooks, I am doing simple programming,
but throwing the results into DNN.


*Free Lunch*
I have to say I agree with you, there are limitations everywhere.  My
appoach is always to keep it as simple as possible until I absolutely know
that I need to make it more complex.

Mark

Hi Mark,

<<<
*Slow Data Contexts*

What do you mean by that? - editing and saving your DNN Data Context Objects
source code in \AppCode subfolder?
What do you mean by "Dbml"?

<<<
but have created about 20 module so far
like this.

OK, I have also made 30+ DNN5.x custom modules properly packed etc. - all
very similar to each other but to get the first one was a time-consuming

Thank you.

tables.  Because of the size of these tables and the processing involved I find it useful to store 
each table in it's own database.  These are just lists of names, each list comes from a different 
source and is called something by the client, something that makes sense to him.  These lists (a 
table) will always be millions of names / addresses, and often are 50 million or more.  When you 
have 50 million names, the database, with just this one single table will be 10 or 20 gigabytes. 
Once you start processing it can mushroom to 50 gigabytes.  Thus storing a dozen of these tables in 
a single database just doesn't make sense (to me).

Thus I have a dozen different databases.

I have to apply all of these stored procedures to each one of these databases once a month.  Thus 
write the stored procedure such that I can pass in a database name and a table name.  Voila, the SP 
works for all of my databases.  But that means dynamic SQL.  I really don't have an issue with 
dynamic SQL, although I have witnessed first hand the time required for SQL Server to do the 
"compile" - creating the execution plan.  If I run the SP a second time with the same db and table 
name the time to execute drops sharply.

BTW, these lists become the source for "orders" of names.  Each of these orders also are stored in 
its own database, and I have to execute these same (or similar) SPs against each of these orders. 
Over the last 4 years I have perhaps a hundred of these order databases.

This is what I do for this client, create these databases, and apply processes against these 
databases.  The processes are exactly the same across all of the databases, thus having a stored 
procedure that performs some part of that process but can be applied to any of these databases makes 
sense (to me).

I have spent the last five years performing these processes entirely manually, then one by one 
creating a stored procedure to automate one of the steps, then the next step, and the next.  By now 
I have an entire master library with (let me go check) 42 different stored procedures that, taken 
together, automate my work for the client.

THAT is the point of the C# side of things.  Automating the automation so to speak.  Taking these 42 
stored procedures and stringing sets of them together, 7 which perform the output of data to an 
external program for processing, 6 more that get the processed data back in, a half dozen more that 
perform some other processing, another set that do order processing, etc.

This is not a bank, or a company or a call center or a manufacturer, or any of the other "typical" 
SQL Server databases.  It is name / address list processing and creating orders from these lists. 
Really pretty simple but extremely painstaking.  And like anything else we do, I can't be making 
mistakes, it must be done in a specific manner, a specific sequence, EVERY time.

Subject: [dba-VB] Read XML File Using xsd Schema File
Message-ID: <38c884770912020805s570c99e1ia753bf4f81b4d0f7@mail.gmail.com>

To all,

We have been a given what looks to me like a fairly complex XML file, we
have also been given a xsd schema file.  I tried using the SQLXMLBulkLoad
object in VB6 and was getting the error

Schema: relationship expected on 'Company'.

The company that gave us both the files insist that the xsd is correct
(according to my project manager).  I downloaded and installed Stylus Studio
2010, with which I loaded the XML, and then generated my own xsd schame
file.  Tried again and this time get the same error as above, but instead of
'Company' the error was 'Groups'

The VB6 code I am using is as follows:

Dim objBL

Set objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad")
objBL.ConnectionString = "Provider=SQLOLEDB.1;Password=hermes;Persist
Security Info=True;User ID=sa;Initial Catalog=XLTestCD;Data Source=AL-SQL1"


objBL.KeepIdentity = True

objBL.errorlogfile = "C:\XML_StylusStudio\Error.log"

objBL.checkconstraints = True
objBL.xmlfragment = True
objBL.schemagen = True
objBL.sgdroptables = True

objBL.Execute "C:\XML_StylusStudio\newschema.xsd",
"C:\XML_StylusStudio\CDFull_Original.xml"
Set objBl=Nothing

The object of the exercise being that we generate related tables in SQL
Server 2005 of the XML data.

Would be grateful if anyone could help with this (would be happy to send
example XML file and the schema offline), as I haven't got much hair left to
pull out.

Thanks in advance for any help on this.

Hi John --

Thank you for your reply.

Do you use your different databases for data input, or you also have to
update those different databases' tables?

Hi John et al

Don't forget LINQPad.

Hi John

As I see it, that would be LINQ and ADO.NET EF (Entity Framework). Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you. Critics tell that this SQL could be long-winded (= not optimized) but what do I care? If it flips 17 or 87 switches does nothing to me as long as the result is fast and precise.

ADO.NET EF is an amazing piece of work. It is not mature but if MS continues to evolve it with the same speed as Silverlight I'm sure it will catch up.

As previously mentioned, over the last couple of years I have built up a set of stored procedures 
which perform TSQL.  I then run sets of these stored procedures to perform processes.  The TSQL is 
always dynamic.

As an example a stored procedure might build a table, with boilerplate field names and data types, 
but a passed in database and table name.  Inside of the stored procedure I build up the correct SQL 
to create the table in the database specified, with the name specified.  Another stored procedure 
might create in index, with boilerplate field names, but a passed in database and table name.  Again 
the stored procedure builds up the TSQL statement to create the index in the correct db and table.

I already have these stored procedures debugged and working and have been using them in sets to 
perform "big picture processes" for quite some time, but the whole "execute a stored procedure" 
using a command object, parameter objects in a parameter array, interpreting the parameters etc just 
seems so... 1950s.  I feel like I am flipping switches on the front panel of a computer in a 50s 
sci-fi movie as a tape reel spins madly in the background.

Now that I am moving to C# I am wondering if this is required any more.  Can C# execute TSQL 
directly somehow?  Can I assemble this boiler plate plus database / table kind of thing into a TSQL 
statement directly in C# and then somehow tell SQL Server to execute that TSQL?  I understand the 
"SQL optimization" thing but it seems like (not sure here) that because the TSQL is dynamically 
constructed in the stored procedure, the whole "optimization" thing goes right out the window.  If I 
can execute TSQL directly from C#, what can I get back?  Rows affected?  Error codes?  And how?

As it stands I am happily flipping switches, tape reels whirring, exporting data for address 
validation.  This is good, I am happy, but ...

Shamil,

I receive lists of names in CSV or fixed width files.  I import those into SQL Server, creating a 
PKID in the process.  I then have to export the PKID plus the name / address monthly for address 
validation.  Once validated, I have to import the data back in.  This is the monthly process. 
Approximately 1% of all the people on any given list move each month.  So I have to go back in to 
the original list and update 1% of the addresses, or simply swap out the new list (table) for the 
old.  There is never any manual processing of individual names inside of these lists, IOW people 
never look at them, modify them, add new ones, delete address or anything like that.  The list is 
"stable" in that regard.

These lists become the source for orders of names.  Orders are a whole 'nother process, but also use 
SPs to do their thing.

Have you tried to use MS SQL database filegroups and partitioned tables &
views?

http://msdn.microsoft.com/en-us/library/ms345146(SQL.90).aspx

With them I suppose only initial import/insert of data have to be
parameterized with table name, and the rest can be done without any dynamic
T-SQL. Please correct me if I'm wrong.

Please note I'm not trying to "force" you to change your current working
solution - just wondering is there a legal way to solve your task without
dynamic T-SQL...

Shamil,

I have not.

All of that is rather esoteric stuff for a non DBA.  My job is processing data, and that is only a 
small part of my job, i.e. this is only one of many clients, and the only one that needs this kind 
of SQL Server stuff.

As I have said many times, if my job was to go into a company every day and play DBA then I would 
learn many more things SQL Server related.  As things stand I learn just enough to make things work, 
and a LITTLE extra in search of efficiency.  It is certainly not that I don't want to, I just don't 
have the time.

In the end I find the method I use comfortable from many angles.  I have to do some things that 
require creating views, other "processing" tables and so forth.  It really just works (for me) to do 
things this way, have separate databases to hold all of the "junk" associated with each list.  Kind 
of the old "encapsulation" thing.

Your suggestion would of course end up with all tables inside of a single "database", and as such 
the need for the Database parameter would go away but I still have to do the same thing to many 
different tables.

Again, could this be done by one of the experts on the SQL Server list.  Probably!  Will I ever get 
there?  Uhhhh doubtful.

forms/number of reports, etc.  But I can't find it in my archives.

I'm having a (friendly so far) discussion with a client who has given me an
extremely ambitious schedule for converting a big Access project to C#
ASP.NET, and I'd like some ammunition for my side of the argument!

Hi Doug,

I used this site as well in making a quote to convert an Access System to a
VB System.

Good Luck!

Hi John --

OK. Don't break it with implementation of other approaches if it works...

Just for the future projects - I suppose (I might be missing something as I
do not have that experience but I plan to try, maybe within our
Northwind.NET project) this partitioning stuff is just practical for the
tasks as you do (similar stuff was available for non-relational DBMSs in the
end of 70-es/beginning of 80ies, and for Oracle it's available for years now
AFAIHH), and this stuff doesn't take that much time to learn (one day?)  and
use (a few short reusable T-SQL scripts?) that it would  take to program and
to test and to support dynamic T-SQ: for many SPs and UDFs...

Thank you.

Subject: Re: [dba-VB] C# - Direct data manipulation

Shamil,

I have not.

All of that is rather esoteric stuff for a non DBA.  My job is processing
data, and that is only a 
small part of my job, i.e. this is only one of many clients, and the only
one that needs this kind 
of SQL Server stuff.

As I have said many times, if my job was to go into a company every day and
play DBA then I would 
learn many more things SQL Server related.  As things stand I learn just
enough to make things work, 
and a LITTLE extra in search of efficiency.  It is certainly not that I
don't want to, I just don't 
have the time.

In the end I find the method I use comfortable from many angles.  I have to
do some things that 
require creating views, other "processing" tables and so forth.  It really
just works (for me) to do 
things this way, have separate databases to hold all of the "junk"
associated with each list.  Kind 
of the old "encapsulation" thing.

Your suggestion would of course end up with all tables inside of a single
"database", and as such 
the need for the Database parameter would go away but I still have to do the
same thing to many 
different tables.

Again, could this be done by one of the experts on the SQL Server list.
Probably!  Will I ever get 
there?  Uhhhh doubtful.

Hi Dan and Doug,

If that stats will help you to quote and to plan your projects, please write
a short note to be posted there (myself or Gustav can post it)

http://northwind.codeplex.com/Thread/View.aspx?ThreadId=54924

This project is currently in suspended state, and good feedback might help
to plan and to implement some useful follow-ups.

Thank you.

Hello Shamil,

In VS2008, when I create a folder in app_Code, and then create a new Linq to
SQL Class is it assigned the extention of dbml, default name is
DataClasses.dbml

It is these classes that are sooo slooow to do anything with.  I timed the
time it takes to just click create, drop a table onto the design surface,
and then click save.  It is taking 4 minutes to do that, so when I needed 20
- 25 objects or so, I have to sit like a donkey and click for almost two
hours.

It still takes four minutes to open and edit one.

A PITA for sure.

If I open the class as a standalone file, I can operate with
instant performance, but it does not play well with the project/ solution.

I have to say, I wish I knew more about these data classes and how they
really should be used in real world applications.

Thanks

Mark

Hello Mark --

OK, I suppose you can create custom DLL(s) working with LINQ to SQL in a
solution outside of your custom DNN solution, and then just use your custom
DLL within custom DNN solution - your LINQ to SQL objects from DLL should be
public and this DLL should also have its own config file...

I have done something like that but with POCO-objects
(http://en.wikipedia.org/wiki/Plain_Old_CLR_Object), which I used as
ObjectDataSources for web forms within DNN custom solutions' custom
modules...

Thank you.

Hello Shamil,

I guess this is an option for me, but to be honest, it will probably more
easier  for me to take the delay of waiting that attempt to manage the
additional layer of complexity.  As with all things in life, I suppose if I
take the time to review this, it will save me time, but I am afraid to spend
a day on it only to save myself a few minutes a few times a day.

Thanks any way for the suggestion,

Mark

I want to create application settings for things like the server instance that the program will bang

Hi John,

Is this what your after?

 
global::WindowsFormsApplication1.Properties.Settings.Default.TestSetting
= "New Value";
 
global::WindowsFormsApplication1.Properties.Settings.Default.Save ( );

cheers

Michael M

I want to create application settings for things like the server
instance that the program will bang 
on, the name of my database that I save my custom UDFs and SPs in etc.
It is trivial to get there 
in the interface but Google is not my friend tonight in discovering how
to access / modify them 
through code.

Anybody?

Create an xml file called UserSettings (or whatever) and store each value in a node in that.  Then all you have to do is read them back when you need them.  We use several of these, one called OLEDBSettings.xml that looks like this: 

  <?xml version="1.0" standalone="yes" ?> 
- <NewDataSet>
- <connection>
  <dbtype>0</dbtype> 
  <provider>Microsoft.Jet.OLEDB.4.0</provider> 
  <datasource>C:\Documents and Settings\All Users\Application Data\Infostat\RIMDrill\5\RIMDrillData.mdb</datasource> 
  <userid>RIMUser</userid> 
  <password /> 
  <initialcatalog /> 
  <trusted>false</trusted> 
  </connection>
- <connection>
  <dbtype>1</dbtype> 
  <provider>sqloledb</provider> 
  <datasource>infoserver</datasource> 
  <userid /> 
  <password /> 
  <initialcatalog>RIMDrillDataSQL</initialcatalog> 
  <trusted>true</trusted> 
  </connection>
  </NewDataSet>

We actually have a file like this for each application and it lives in the application folder.  This is just to give you an idea, not a how to.   We have a class that wraps this in our apps and uses this kind of routine to read it.  I leave it up to you to translate to C#.

    Shared ds As DataSet
    Shared _connectionString As String

    Shared _xmlPath As String = "OLEDBSettings.xml"         'default to xml file in apppath

   Private Shared Sub ReadSettingsFile()
        If IO.File.Exists(_xmlPath) Then
            Call CreateSchema()
            ds.ReadXml(_xmlPath)
            Call DecryptPassword()
            _connectionString = GetConnectionString()
        Else
            If ds.Tables(0).Rows.Count = 0 Then
                'placeholder for jet settings
                Dim row As DataRow = ds.Tables(0).NewRow
                row("dbtype") = 0
                row("provider") = "Microsoft.Jet.OLEDB.4.0"
                ds.Tables(0).Rows.Add(row)

                'placeholder for sql settings
                row = ds.Tables(0).NewRow
                row("dbtype") = 1
                row("provider") = "sqloledb"
                ds.Tables(0).Rows.Add(row)
            End If

    End Sub

  Private Shared Sub CreateSchema()
        ds = New DataSet
        Dim table As New DataTable("connection")
        table.Columns.Add("dbtype", GetType(Integer))
        table.Columns.Add("provider", GetType(String))
        table.Columns.Add("datasource", GetType(String))

Hi Charlotte,

I see this as useful, but,
If you need a complex setting structure why not just create a
'MySettings' class and serialise or deserialise it as needed?
I think John has already worked with the Serializable attribute.
Am I missing something?

Cheers

Hi John

Yes and no. I used an old version for some time but the current version is more powerful.

Please note that it comes with all the examples from his book, and even without the book this is a great why to get your hands on LINQ as the code is "live" - no need to copy and paste, it is right there for you try out at once.

Hi John et all

Further to the notes below on Joseph Albahari's LINQPad, it contains a link to download all the example code from "LINQ in Action".
Also, it has a link to this amazing demo of the power of LINQ:

http://blogs.msdn.com/lukeh/archive/2007/03/19/using-linq-to-solve-puzzles.aspx 

It's a true eye-opener and a good example showing that the scope of LINQ is much wider than "normal" database querying.

The code is included in LINQPad when downloaded, ready for you to play with at:

  Tab Samples, 
  C# 3.0 in a Nutshell, Chapter 9 - LINQ Operators, Joining, Extra - Weights Puzzle. 

It's Friday and soon weekend!

Message-ID: <38c884770912040419xdc61c66y2c315b820cd6fb09@mail.gmail.com>

To all,

We have been a given what looks to me like a fairly complex XML file, we
have also been given a xsd schema file.  I tried using the SQLXMLBulkLoad
object in VB6 and was getting the error

Schema: relationship expected on 'Company'.

The company that gave us both the files insist that the xsd is correct
(according to my project manager).  I downloaded and installed Stylus Studio
2010, with which I loaded the XML, and then generated my own xsd schame
file.  Tried again and this time get the same error as above, but instead of
'Company' the error was 'Groups'

The VB6 code I am using is as follows:

Dim objBL

Set objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad")
objBL.ConnectionString = "Provider=SQLOLEDB.1;Password=hermes;Persist
Security Info=True;User ID=sa;Initial Catalog=XLTestCD;Data Source=AL-SQL1"


objBL.KeepIdentity = True

objBL.errorlogfile = "C:\XML_StylusStudio\Error.log"

objBL.checkconstraints = True
objBL.xmlfragment = True
objBL.schemagen = True
objBL.sgdroptables = True

objBL.Execute "C:\XML_StylusStudio\newschema.xsd",
"C:\XML_StylusStudio\CDFull_Original.xml"
Set objBl=Nothing

The object of the exercise being that we generate related tables in SQL
Server 2005 of the XML data.

Would be grateful if anyone could help with this (would be happy to send
example XML file and the schema offline), as I haven't got much hair left to
pull out.

Thanks in advance for any help on this.

Hi John

Oh, I misunderstood you.
Not until recently. Skipping the SQLCommand low-level stuff completely, I've used datatables with in-line SQL queries (to avoid designing T-SQL and special views - Shamil mobbed me for that choice!) and I have been busy learning just these - so one step further, no thanks. Also, I had a hard time grasping the lambda expressions and syntax and still feel I have a lot to learn. Yes, you can use LINQ without lambda, but that seems like LINQ without an arm and a leg. But - for anything else than some special cases like perhaps your cases - I'm confident LINQ is the route to follow.

I have to say that as a developer of a higher level language, I can see where avoiding TSQL would be 
  something we would try to do.  While I understand that SQL Server can be integrated into and used 
straight from the VS environment, most of us come at it from the built-in editor which frankly 
sucks.  And I mean REALLY BADLY sucks, no apologies to our admin friends.  I guess I have been doing 
SP development for a couple of years now and I still hate the built-in editor.  And yet... that is 
what I use.

IMHO this is an area where MS has fallen down on the job.  If this integration thing is so darned 
simple, then MS should push education, seminars, books, education, education to get us working in VS 
to run (program) SQL Server.  From a development perspective, and that is what SPs and UDF are after 
all, SQL Server should just be a tool used to manipulate data, NOT a dev environment.

Over the last month I have found two APIs that allow C# to do a ton of stuff directly in SQL Server. 
  WAY COOL stuff, but you would think it was porn the way you don't see it in the mainstream.  These 
APIs allow you to manipulate SQL server the same way you can manipulate any other object - create, 
delete, observe, modify, manipulate anything in SQL Server - straight from VS.  But where are the

Charlotte,

My question really is how do I get at the settings area of the project, and why would I not use that 
instead of this xml thing of yours?  At least in this specific case, I am writing code for myself,

Hi John

One reason could be that many web developers know little about database design, thus they are being forced to leave that to a DBA. A chief developer once told at a tech meeting I attended, that they operated with the concept "scared of the database" meaning that the web developers should just be presented with ready-made views because SQL to these was like black magic.

mobbed me for that choice!)

I have to say that as a developer of a higher level language, I can see where avoiding TSQL would be 
  something we would try to do.  While I understand that SQL Server can be integrated into and used 
straight from the VS environment, most of us come at it from the built-in editor which frankly 
sucks.  And I mean REALLY BADLY sucks, no apologies to our admin friends.  I guess I have been doing 
SP development for a couple of years now and I still hate the built-in editor.  And yet... that is 
what I use.

IMHO this is an area where MS has fallen down on the job.  If this integration thing is so darned 
simple, then MS should push education, seminars, books, education, education to get us working in VS 
to run (program) SQL Server.  From a development perspective, and that is what SPs and UDF are after 
all, SQL Server should just be a tool used to manipulate data, NOT a dev environment.

Over the last month I have found two APIs that allow C# to do a ton of stuff directly in SQL Server. 
  WAY COOL stuff, but you would think it was porn the way you don't see it in the mainstream.  These 
APIs allow you to manipulate SQL server the same way you can manipulate any other object - create, 
delete, observe, modify, manipulate anything in SQL Server - straight from VS.  But where are the 
forums, the blogs, the developer excitement?  It appears to me that there is a very real "here is 
your database" aimed at the developers who use SQL Server, and the admins just do things the way 
they always have for the last 20 years.  And they buy tools from the RedGates of the world who 
undoubtedly do salivate over these new APIs.

Just my humble opinion.

I actually think that is a good thing, developers who just use data shouldn't need to be learning 
SQL Server to get their data.

That is really not the audience I am addressing however.  IMHO the built-in editor of SQL Server 
should either be removed entirely or at least brought into the current century.  It is notepad with 
pretty colors.  How many millions of man hours have been wasted trying to track down errors when the 
only error message presented was "error near (insert some unrelated thing here)".  Why bother even 
throwing up an error like that, and that is 99.9% of the errors I have EVER seen in two years 
working with SQL Server.

Notepad, with pretty colors.

For all of the rude comments us Access developers get about Access being "a toy", the code editor in 
Access is in a complete other galaxy from the code editor in SQL Server.  SQL Server editor looks 
like it was designed in 1986 and never upgraded.

Of course with the "real men don't use code editors" mentality of the DBA side of the fence I can 
see why MS doesn't bother spending time on this.

Someday I really am going to have to figure out how to use VS to run / debug my SPs and stuff.  To 
me VS just seems over-the-top complex for the level of stuff I am trying to do.  An Access type of 
code editor would be just the right level of convenience and capability - built right into SSMS.

Hi John

LINQPad does pure SQL too, though not with IntelliSense, and error messages seem to be those from SQL Server.

Under the project is a properties object.  Double click that and an entire multi-tabbed dialog opens.

Click the settings tab.  There you will see a form where you can enter name, type, scope, value.

As far as I can tell this is a place where I (the developer) can create settings that my program 
will use and manipulate, settings (for example) to tell my program the name of the SQL Server 
instance to use in a connection string, the name of my control database where I store my stored 
procedures and UDFs.  Stuff like that.  Stuff that I am currently hard coding, but which really 
should be in a settings tab so that I don't have to remember where that constant is in code, I can 
just go to the settings tab to change.

My expectation is that there is an object somewhere in the .net namespace that allows you to do 
something like "Something.Somethingelse.Settings["MyServerName"]...." to access these things.

I expect to be able to create new ones, edit existing ones, delete them etc from a .Net object.  I 
am looking for that .Net syntax that allows me to do this from code.

Hi John,

You can access those properties using:

Properties.Settings.Default.{{PropertyName}}

Or

{{Root Namespace}}.Properties.Settings.Default.{{PropertyName}}

Hi John

Shamil is right, but that method is for reading only.
Please note that the Properties' collection object is read-only, thus it takes quite a few steps to add a property:

http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/c52b4fc6-66be-44ce-8a65-ab548f6f4f04

I have not used this as I haven't had any need to add properties on the fly. Reading and writing was fine for me, and new properties I added manually.

You may find it much easier and perhaps more convenient to just have a dataset which you read and write from/to an XML-file. I've posted code for this before.

Under the project is a properties object.  Double click that and an entire multi-tabbed dialog opens.

Click the settings tab.  There you will see a form where you can enter name, type, scope, value.

As far as I can tell this is a place where I (the developer) can create settings that my program 
will use and manipulate, settings (for example) to tell my program the name of the SQL Server 
instance to use in a connection string, the name of my control database where I store my stored 
procedures and UDFs.  Stuff like that.  Stuff that I am currently hard coding, but which really 
should be in a settings tab so that I don't have to remember where that constant is in code, I can 
just go to the settings tab to change.

My expectation is that there is an object somewhere in the .net namespace that allows you to do 
something like "Something.Somethingelse.Settings["MyServerName"]...." to access these things.

Hi Gustav,

You can set 

Properties.Settings.Default.{{PropertyName}} = {{SomeValue}};

and save settings having "User" scope:

Properties.Settings.Default.Save();    

And they are saved not in {{ApplicationExecutableFileName}}.config, which
you deliver with you app's executable but anywhere else on your system -
probably somewhere in user's Application Settings - standard windows folder.
I have never had time to find out where settings are saved. Anybody?

Recap:

- settings are loaded from {{ApplicationExecutableFileName}}.config when you
deliver you application, and it runs first time;
- as soon as you save "User" scope settings they are saved in and loaded
from {{UnknownPlace}};
- if you move your application files into another folder on the same system
the settings are again loaded on first run from
{{ApplicationExecutableFileName}};
- ...

That looks confusing a bit but it's how it works...

You can click "Learn more about application settings..." on top right of
VS2008 application settings window available by Solution Explorer -> Project
name -> Right-Click -> Settings...

But if you wanted to have rather complicated structure of your application
settings file then better use your own custom XML files, which can be loaded
from/saved to files many ways without almost any coding...

Thank you.

No, PropertyName can't be appended and saved if it doesn't exist as they are
compile-time (early) bound - but JC asked exactly about existing properties
defined in VS2008 project settings, and they can be changed and saved if
they have "User" scope.

Yes, I guess they are saved somewhere in AppData but I do not know where...

Hi Shamil

Well, much less hard-core than I had expected, indeed not a coding session but with a good perspective.
However, he came a long way describing and demonstrating many new features of VS2010, MVC and Silverlight. Also LINQ and ADO.NET EF seems to be mainstream. And, of course, much warmly promoting of Windows Azure which works very well together with VS, indeed with the new "local Azure" - a local simulator of Azure you can use during development so no live hosting is needed - much like the local web server that simulates IIS.

Very cool is the new GUI designer for Silverlight UI design. VS2010 is brushed up quite a lot with better support for multi-monitor use, improved IntelliSense and editing features in the code editor - everything is aimed at faster development with firm focus on you, the developer, very different from Access.
Further, the Team Foundation edition is now useful for single developers too, with unit testing, versioning etc. etc. However, I expect that to be available at a "corporate" charge only (beyond my budget), but let's see.

He promised to mail us links to the complete session and much more. I can post these here when they arrive.
If you or anyone else have questions to specific topics, Scott Guthrie may have touched, please ask.

local simulator of Azure you can use during development so no live hosting
is needed - much like the local web server that simulates IIS.

Very cool is the new GUI designer for Silverlight UI design. VS2010 is
brushed up quite a lot with better support for multi-monitor use, improved
IntelliSense and editing features in the code editor - everything is aimed
at faster development with firm focus on you, the developer, very different
from Access.
Further, the Team Foundation edition is now useful for single developers
too, with unit testing, versioning etc. etc. However, I expect that to be
available at a "corporate" charge only (beyond my budget), but let's see.

Hi Shamil

Well, much less hard-core than I had expected, indeed not a coding session
but with a good perspective.
However, he came a long way describing and demonstrating many new features
of VS2010, MVC and Silverlight. Also LINQ and ADO.NET EF seems to be
mainstream. And, of course, much warmly promoting of Windows Azure which
works very well together with VS, indeed with the new "local Azure" - a

I want to create application settings for things like the server
instance that the program will bang 
on, the name of my database that I save my custom UDFs and SPs in etc.
It is trivial to get there 
in the interface but Google is not my friend tonight in discovering how
to access / modify them

Anybody?

Hi Shamil

Well, much less hard-core than I had expected, indeed not a coding session
but with a good perspective.
However, he came a long way describing and demonstrating many new features
of VS2010, MVC and Silverlight. Also LINQ and ADO.NET EF seems to be
mainstream. And, of course, much warmly promoting of Windows Azure which
works very well together with VS, indeed with the new "local Azure" - a
local simulator of Azure you can use during development so no live hosting
is needed - much like the local web server that simulates IIS.

Very cool is the new GUI designer for Silverlight UI design. VS2010 is
brushed up quite a lot with better support for multi-monitor use, improved
IntelliSense and editing features in the code editor - everything is aimed
at faster development with firm focus on you, the developer, very different
from Access.
Further, the Team Foundation edition is now useful for single developers
too, with unit testing, versioning etc. etc. However, I expect that to be
available at a "corporate" charge only (beyond my budget), but let's see.

He promised to mail us links to the complete session and much more. I can
post these here when they arrive.

OK, it appears that each project has its own set of properties.  If I set the same property in the 
current project's property set then

Properties.Settings.Default["ServerName"].ToString()

works just fine.

But that is not the behavior I want.  I need a SOLUTION property set, which appears to not exist? 
Which perhaps would explain why those who have done this before roll their own?

Does anyone have code to do this so I don't have to roll my own (a.k.a. reinvent the wheel) too?

Hi John

The file containing the settings is app.config.

To hold "global" settings you could create a small project with just this file and reference it from any other project.

My understanding of Properties.Settings is that settings must be by User
in order to be saved and the xml file will reside in the Local 
Setting/Applications
directory under the user's My Documents folder.

In that case, all projects under a solution could read a single xml file.

We decided to use cryptographic services for the i/o of the xml by
using an internal static class that reads/writes to a string collection
using methods we created like bof, eof, movefirst, addnew, etc.

Hi John --

For solution you can select one of the projects to be used to handle
settings.
That project is usually a core(utility/generic/settings) class library.
Then if you wish you can additionally wrap 

Properties.Settings.Default...

for every/most of the settings into your custom global (Solution scope)
properties' wrappers. Such wrapping makes your referencing projects
independent on actual implementation of handling of application settings.
When that done and works OK you can go and "reinvent the wheel" if needed
without any changes in referencing projects...

Subject: [dba-VB] C# - Thoughts on my methods
Message-ID: <4B1FC705.9010902@colbyconsulting.com>

As a consultant in a home office I work in total isolation except for this email group.  So I need 
your input, to keep me sane and to keep me on the right path.  I would like your thoughts on what I 
am doing and what I am intending to do.

As you know, I have "the database from hell", for which I am developing an application to allow me 
to manipulate the various pieces from an application interface rather than directly from stored 
procedures and the SSMS or from Access, which is what I have done to this point.  With C# I am able 
to do more than I was able from Access, including getting back output parameters from stored 
procedures.  So... my process so far.

First off, I am developing the overall application as a set of child projects inside of the 
application.  The main application opens a form with a menu, and that menu takes me to forms in the 
child projects to perform pieces of the application.  For example I have a database backup project 
where I can backup and restore specific databases or groups of databases.  I have an Accuzip project 
where I can export CSV files to and import resulting CSV files from the external Accuzip program.  I 
have an Orders project where I can create and manipulate the orders I create for the client.

Each child project is physically located underneath the main application directory.  In order to 
reference (open) the forms in the child projects, I have to set a reference to that project and I 
have to set a using statement in the form.  I still do not understand what these two pieces do.  Why 
do I have to set a reference and a using?  I assume you cannot set a using statement unless the 
project references the library (or project)?

I also don't understand why some objects in a referenced project class can be seen but others 
cannot.  IOW I can use one class in a namespace as a type to dimension an object, but another class 
in the same namespace is not visible, cannot be so used.

I don't understand a whole ton of things of this nature and I have to say that the whole "break into 
projects" idea is turning out to be more work than it might be worth.

Any comments on this email will be much appreciated.

Subject: [dba-VB] threading
Message-ID: <4B1FF708.1040700@colbyconsulting.com>

As mentioned in previous emails, I am developing an application to manage all of the tasks for the 
DBFH.  This includes Backing up databases, creating orders, transferring data between an external 
app etc.  I am trying to determine how to thread this app such that if I start a process exporting 
data to Accuzip, I could have another process importing data from Accuzip, and also be working on an 
order.

As things currently stand, each of these tasks is a project and each project has its own forms and 
classes, and anything else necessary for that task.  I really do want to be able to do multiple 
things like this at the same time.  Exporting data to Accuzip can take overnight, and actually 
consists of an export and a matching import process.  It makes perfect sense (to me) to have threads 
doing this kind of thing, and allow me to go back to the main application and do something else.

But at what level would I use a thread?  Would I use a thread to open the form that performs the AZ 
process?  This would allow me to get that started and immediately go back to the main app and open 
another form (using a new thread?) to start processing an order.

Or would the form open and the button on the form start a thread that executes the process?  If a 
form starts a thread, that allows the user (me) to do other things in that form potentially changing 
to a new directory or selecting a different database.  Do you disable all controls on a form when a 
thread starts?  I never had to think about this in VBA and it is all rather confusing.

Why not have several (FE) applications if they are so independent? - all

Hi John,

Have a look for DotNetNuke sources - they have free sources for
zipping/unzipping.
Those sources are used in core DNN functionality (modules setup) - IOW they
tested well, they are stable and thry work very well.

Hi John --

In fact this is easy (please correct me if I'm wrong):

- just reference your child projects from your main project and if you have
(sub-)child projects then reference them from child projects; you can also
reference child-child-(nephew) projects from parent projects etc... - just
avoid having circular references...

All that is very similar to MS Access/VBA references but unlike in MS
Access/VBA in .NET solutions this referencing always work without any
glitches whatever size your solutions are - tens of projects, thousands of
customer classes - no problems, no GPFs of Visual Studio (well, for ASP.NET
and WPF solutions you can have GPFs but even in that case you'll have all
your sources preserved).... 

<<<
I also don't understand why some objects in a referenced project class can
be seen but others 
cannot.  
>>>
That should be your problem/issue: in VS2008 (Prof) you can always try to
hint VS asking to "resolve" undefined class name, enum, global var - right
click -> Resolve... - if it can't do that - you can always do that manually
- but it may be needed to have some custom classes "shuffled" between your
projects...

<<<
the whole "break into 
projects" idea is turning out to be more work than it might be worth.
>>>
John, it will pay itself back very quickly - just be patient - I'd guess
(based on your software development experience) it will need max one week
(in total) of your time to spend mastering that multi-project solutions -
and when you're there - only outer space will be your limitation...

Just create a very simple sample solution with several projects and try to
play with it setting references, moving custom classes from one project to
the other, changing namespaces, and using directives... it's really easy -
imagine hierarchical catalog where child entries can be referenced/accessed
from parent ones, but where sibling entries aren't aware of each other...
(if only they do not inherit from the same parent entries...) 

Thank you.

Subject: [dba-VB] C# - Thoughts on my methods

As a consultant in a home office I work in total isolation except for this
email group.  So I need 
your input, to keep me sane and to keep me on the right path.  I would like
your thoughts on what I 
am doing and what I am intending to do.

As you know, I have "the database from hell", for which I am developing an
application to allow me 
to manipulate the various pieces from an application interface rather than
directly from stored 
procedures and the SSMS or from Access, which is what I have done to this
point.  With C# I am able 
to do more than I was able from Access, including getting back output
parameters from stored 
procedures.  So... my process so far.

First off, I am developing the overall application as a set of child
projects inside of the 
application.  The main application opens a form with a menu, and that menu
takes me to forms in the 
child projects to perform pieces of the application.  For example I have a
database backup project 
where I can backup and restore specific databases or groups of databases.  I
have an Accuzip project 
where I can export CSV files to and import resulting CSV files from the
external Accuzip program.  I 
have an Orders project where I can create and manipulate the orders I create
for the client.

Each child project is physically located underneath the main application
directory.  In order to 
reference (open) the forms in the child projects, I have to set a reference
to that project and I 
have to set a using statement in the form.  I still do not understand what
these two pieces do.  Why 
do I have to set a reference and a using?  I assume you cannot set a using
statement unless the 
project references the library (or project)?

I also don't understand why some objects in a referenced project class can
be seen but others 
cannot.  IOW I can use one class in a namespace as a type to dimension an
object, but another class 
in the same namespace is not visible, cannot be so used.

I don't understand a whole ton of things of this nature and I have to say
that the whole "break into 
projects" idea is turning out to be more work than it might be worth.

Any comments on this email will be much appreciated.

That's why in our apps we keep all the forms in a project, all the reports in a project, etc.  Of course, if we were using libraries rather than projects under the solution, it would be different.

You can roll your own using J# from within VS.  Idid that originally and it only takes minor translation to put it into C# or VB.  That said, we currently use Xceed.

Subject: [dba-VB] Ajax application problem
Message-ID: <3262DDC894CA427DB254732FCE5E70AF@VOSTRO>

Hi all,


I have problems putting an ajax application on a production server.

The application consists of an aspx page that keeps the javascript code.
This code talks with C# page methods to access Web services and interact with the database.

For example the first thing the user has to do is fill in login and password fields and click on the btnLogin.

Then the code execute the following command:
PageMethods.GetUser(user, onGetUserSuccess, onGetUserError);

with user being an array containing username and password. The C# GetUser webmethod returns its response to the onGetUserSuccess callback function.

The application runs ok on my dev pc.

I installed it on the production server, copying the aspx file, web.config file and the binary files.

When I run it, I get an error message, something like error during the handling of your request.(freely translated from french!!)

This error is displayed into a textbox by the onGetUserError callback function. 
I put an error trapping withing the webmethod, but its error message is not returned, leading me to think that this webmethod is not "entered".
Therefore the javascript code is running ok, but the call to the webmethod is failing.

I guess I missed to copy something like a javascript file from the framework, or something else.

Do you have any kind of experience in this regard?

NB: I also checked that the asp framework is of version 2.0 on the server, it's ok.

TIA,

Philippe Pons

Hi Charlotte --

Yes, it's easy to create cross-refs, and it's (usually) easy to solve
cross-refs under Visual Studio - please provide an example where cross-refs
resolving is a really tough task - this sample shouldn't be the case where
one decides to resolve cross-refs in a legacy "spaghetti" set of projects
IOW we assume we're talking about experienced developers who prevent having
"cross-refs" spaghetti by doing code
clean-up/refactoring/de-cross-referencing once in a while within a project's
sources life-time...

 > Why not have several (FE) applications if they are so independent? - all developed within one VS 
solution but as separate (WinForms) projects sharing the same (set of) class library(-ies)?

It seems like that may be what I am doing?  I have a single solution.  Inside of that solution's 
physical directory I have multiple projects, each in its own directory.  As I expand the solution I 
do an add / new project from the main solution / project.  Doing that takes care of creating a 
directory structure for each new project, but causes it to be created under the main solution directory.

Each project does not depend in any way on any other project, though I do have some shared 
libraries.  Each child project is referenced by the main project, but the child projects do not 
reference other child projects.

Now whether each of these independent projects ends up as individual applications I don't have a 
clue.  I was just tying them together with a single form / menu so that I have one central 
application to go to to find everything.

Thanks, but I am quite sure I would just get lost.  You have way too much faith in my C# abilities 
at this point in time.  ;)

I have found at least two dlls that can be referenced and used from C#.  Each claims to be "managed 
code" and make the source available, though what that is worth to me is not clear.  I just want 
something that is easy to use and documented so I can figure out how to use it.  I have a lot of 
uses for zip files, from zipping up archives of files for near line storage to making true zip files 
for shipping to clients.

 > Have a look for DotNetNuke sources

Thanks, but I am quite sure I would just get lost.  You have way too
much faith in my C# abilities 
at this point in time.  ;)

I have found at least two dlls that can be referenced and used from C#.
Each claims to be "managed 
code" and make the source available, though what that is worth to me is
not clear.  I just want 
something that is easy to use and documented so I can figure out how to
use it.  I have a lot of 
uses for zip files, from zipping up archives of files for near line
storage to making true zip files 
for shipping to clients.

Hi Michael

Neither have I, but I googled a little on the "zubject" and several links tell that this GZip compression is not compatible with WinZip and the like because of missing file info, in other words it should be fine for compressing and decompressing a stream (which of course can be written/read to/from a file) but that's all.

A bit strange that this widely used function is missing from the framework.

Even more strange that someone hasn't wrapped this into a C# class so that it is available as simple

Have I got the book for you.

http://www.amazon.com/Microsoft%C2%AE-XNA%C2%AE-Game-Studio-3-0/dp/0735626588/ref=sr_1_2?ie=UTF8&s=books&qid=1260761698&sr=1-2

I bought this book because I found the XNA studio and wanted to learn all about how it works.  But 
this book is about teaching programming, and from that C#.  For anyone who knows vba or VB.net it 
will start off easy, but for anyone who doesn't program at all it also starts off easy.  This might 
be the best book for learning to program (in general) I have run into.  Plus it is fun.

You need Visual Studio (express is fine) and you need the XNA studio (it is also free).  An XBox 360 
game controller will be required pretty quickly.  I bought the cheapest controller for $15 from 
Wally world.

Then start reading (and writing).  I am on chapter 5 now (in about three days) and working on 
through it.

I swear you will learn C#, have fun while you are at it, AND learn how the XNA game studio framework 
works which is also an awesome tool.

Really folks, this is the real deal, if you have always said "I should..." do this one.  Or get your 
teenager involved in it.

I bought the book new from Amazon for about $20, plus the controller.  Everything else is free. 
That is a great deal folks!

I am working on creating a single field index on every field of a table.  I promptly ran into so 
many problems making it generic that I punted and went back to hard coding the database / table 
name.  I did find this:

select Name as FldName from psm11203.sys.columns
	WHERE object_id = OBJECT_ID('PSM11203.dbo.tblOrderData')

Which does give me a table of field names.  Using this in a cursor I am then able to create an index 
on each field, so I am off and running.

This is really a one off process that I need to run on my tblHSID - the table from hell from the 
database from hell.

I have to tell you I am a bit hesitant to pull the trigger in this for the table from hell.  It is 
going to take many minutes to build each index and there are well over 500 fields to index.  I could 
end up locking up my database for the next month.  ;)

I did create a copy, created a clustered index and will be creating all of these indexes on that 
copy, but even then it pretty much uses all of the resources of the server.

Subject: [dba-VB] A Parameters syntax question
Message-ID: <c09.73631826.3858baa7@aol.com>

 
Hi All
 
I'm connecting a vb2005 DataGridView to an Access db via vb code to  return 
a subset of records from a table. Using the GUID dataType it works fine  
but when I change the datatype I get all the records.
 
I'm using the Imports system.Data.OleDb class. From there I have OleDb  
connection, Command, DataAdapter and a Dataset.
 
EG.
With Command
    .CommandText = "QueryName"
    .CommandType = CommandType.StoredProcedure
    .Connection = OleDbConnection
    .Parameters.Add("@REFNOC", OleDbType.Guid,16).Value  = New Guid(REFNOC)
end With
 
Every thing works as it should. That is until I change the the datatype in  
the Parameter line and try to use a string or Integer.
 
I can't get the syntax right for the .Parameters line. If for example I  
change the .Parameter to say
 .Parameters.Add("@REFNOC", OleDbType.Single).Value = REFNOC I get all  
records
 
Can anyone cast a little light here?

When using parameters in vb.net connection one does need to specify  the 
parameter in the back-end query!!
 
Then it works a treat

Subject: [dba-VB] windows 7 media center
Message-ID: <4B295D18.7070000@colbyconsulting.com>

Well my Vista Windows Media Center (WMC) finally bit the dust.  Something happened (a SP install I 
suspect) and the codec got trashed (I think) and suddenly WMC no workee - no tv of any kind, already 
recorded or off of the tv card.

As a college student I qualify to buy a copy of Windows 7 for $29 which sounded too good to pass up. 
  And that version supposedly had a much improved MCE.  So I did.  Bought it, and installed it ON A 
30 gb FLASH DRIVE last night.  Finished about 3:30 am.  She workee again.  In the meantime I also 
went from a low power dual core to a medium powered quad core, but twice the ghz rating.  Needless 
to say the Home theater PC flies.  Now if it will just work for a long time with no maintenance.

Subject: [dba-VB] SQL Server 2008 install broke my application
Message-ID: <4B2AEAF5.3080201@colbyconsulting.com>

A perfectly functioning application has all kinds of compile errors after the SQL Server install.  A 
bunch of Microsoft.SQLServer.XXX references had to be deleted and rereferenced.  The sole remaining 
issue that I still haven't gotten around is the Transfer object, supposedly part of the SMO object 
is suddenly gone missing.  And I was using that to copy a database and all of its internal objects.

Sigh.

Hey John,

Did you install the SQL Client Tools?  I was just reading something about
this today.  I think the SMO stuff is installed with the client tools.  I am
not positive though.  If this does not solve your issue, I'll see if I can
find that reference tomorrow.

How come no one told me about this?

Message-ID: <38c884770912240409v7becad65te771430652a0472d@mail.gmail.com>

To all,

I use a lot of recordsets, and to detect they actually contain something I
have always used the following:

If myrecordset.bof=false and myrecordset.eof=false then
    do my stuff here
Else
    msgbox "empty"
End If

However my project manager prefers:
 If not myrecordset.bof and not myrecordset.eof then
    do my stuff here
Else
    msgbox "empty"
End If

Is there actually a prefered way, or is one quicker than the other, or is
there an even better way to do this ?

Thanks in advance for any comments, and a very merry christmas & happy new
year to everyone.

Hi Paul
Well I'll wait to be corrected but I reckon they're simply two syntactically
different ways of saying the same thing. They'd surely compile into the same
code. So it just comes down to preference of style and readability, i.e.
totally subjective

Or you could do this (which I prefer)

If not rst.eof then
Do my stuff
Else
Msgbox "who nicked my records"
Endif

Ps. Who is the programmer?  You, or the Project Manager?

Paul,

Perhaps better would be:

if MyRecordset.BOF and MyRecordset.EOF then
	msgbox "Empty"
else
	do stuff here
endif

It is easier to read the true than the nots, especially when there is more than one.  Either one 
works.  If this is in a tight loop and speed matters, then the NOT might cause a very slight 
slowdown as it is two extra boolean operators.  OTOH the compiler might just pick it up and rewrite 
it to my syntax anyway.

I don't think that will work...something from Getz etc sticks in my

Hello John,

I have struggled with this value, and mixed it up with the connectionTimeout
also.  As a result, when I think there will be a delay, I also set it to
zero, and then I sleep easy.  I did that two years ago with
out troublesome app, and now it works and works and works.  Whats the
downside of infinite timeout.  If it takes three weeks, you will find out
anyway, but why kill it after ten mins when it would have finished
successfully in 19.45 minutes.

BTW how do you kill an executing stored procedure?

Hello John,

Not sure, but stopping the server is one way.  My main problems were sprocs
stopping when I did not want them to stop, for me, if it is still running
after 24 hours, it is probably never going to stop.  For you, you might
increase that to 48 hours, but in general, they either finish promptly, or
else will never finish, either way, timing out after 10, 20, 50, or even 600
minutes is almost never a good option, if there is a possibility that it
will finish in 601 minutes.

There is probably a way to stop a process, Francisco or some of the other
experts may know how, but I would either stop the db server / service, or
else in worst case, do a quick reboot.  For the rest of the year, I would
never worry about it, happy in the knowledge they the server must work till
the death :)

Thanks

Mark

Mark,

 >but I would either stop the db server / service, or else in worst case, do a quick reboot.

I have done both.  I have corrupted the database doing the reboot.  Stopping the service seems to 
work, however I have also seen the database pick up where it left off when the service restarted.

I am sure there is some way to "officially" stop a running process, I just don't know how.

Subject: [dba-VB] C# - Records Affected
Message-ID: <4B153F3A.8010102@colbyconsulting.com>

I am trying to get a count of records appended, updated etc in my SPs and returning that to my C# 
supervisor.  I am finding references to @@Rowcount however this is returning 1 instead of the actual 
number.

Is this @@RowCount the real deal?

The SP definition:

ALTER PROCEDURE [dbo].[sp_AZOut_AZExportToOrderedChunk]
	-- Add the parameters for the stored procedure here
	@DBName varchar(50),
	@ErrorDesc varchar(4000) output,
	@ErrorNo int output,
	@RecsAffected int output

AS
BEGIN


Setting the returned value

	EXEC (@SQL)
	select @RecsAffected = @@RowCount

My c# code:

intRecsAffected = sCmd.Parameters["@RecsAffected"].Value

The code triggers the try block if there is no such parameter (I just ignore it) or returns 1 if the 
parameter exists.

This is a functioning tested SP which typically appends millions of records, though the exact number 
depends on the database.

Is there something I need to know here?

<quote>
Do a select * from sysprocesses and identify the spid in question. Then do a "KILL 
<spidno>"

This will mark the spid as "dead". Note that it may take a while for the process to end as it 
has to rollback all the updates that it has been doing. Also kill only marks the process as 
dead - the process itself needs to check for this, and if it is stuck in a loop as the result of a 
bug or whateverthen it won't terminate. Also certain processes like dump and dbcc 
commands have significant code paths where the kill command is not checked for and so 
these can take some time to terminate.

Also, if the process is in an extended-stored procedure, or is waiting on network 
traffic/remote stored-procedure it will not check whether it has been terminated until these 
actions have been completed.

See Q171224 for more info - including details on the waittype that can tell you what a 
process is waiting on.

If the process won't die for one of the above reasons then your only choice is to stop the 
sqlservr.exe process itself and re-start.

See also http://msdn.microsoft.com/en-us/library/aa933230%28SQL.80%29.aspx
for info on KILL x WITH STATUSONLY for tracking the rollback once you kill a process.

Sorry for the ring, I found the problem.

The SP that I took this code from actually worked but the code I was testing did not and came before 
this code.  The problem was simply that in the SP I did not place the line that captured @@RowCount 
immediately after the EXEC (@SQL) statement.

All of the examples clearly warned me that this was a requirement but you understand "senior moments".

Anyway, this is now working.

Piece by piece this thing is coming together.

As previously mentioned, over the last couple of years I have built up a set of stored procedures 
which perform TSQL.  I then run sets of these stored procedures to perform processes.  The TSQL is 
always dynamic.

As an example a stored procedure might build a table, with boilerplate field names and data types, 
but a passed in database and table name.  Inside of the stored procedure I build up the correct SQL 
to create the table in the database specified, with the name specified.  Another stored procedure 
might create in index, with boilerplate field names, but a passed in database and table name.  Again 
the stored procedure builds up the TSQL statement to create the index in the correct db and table.

I already have these stored procedures debugged and working and have been using them in sets to 
perform "big picture processes" for quite some time, but the whole "execute a stored procedure" 
using a command object, parameter objects in a parameter array, interpreting the parameters etc just 
seems so... 1950s.  I feel like I am flipping switches on the front panel of a computer in a 50s 
sci-fi movie as a tape reel spins madly in the background.

Now that I am moving to C# I am wondering if this is required any more.  Can C# execute TSQL 
directly somehow?  Can I assemble this boiler plate plus database / table kind of thing into a TSQL 
statement directly in C# and then somehow tell SQL Server to execute that TSQL?  I understand the 
"SQL optimization" thing but it seems like (not sure here) that because the TSQL is dynamically 
constructed in the stored procedure, the whole "optimization" thing goes right out the window.  If I 
can execute TSQL directly from C#, what can I get back?  Rows affected?  Error codes?  And how?

As it stands I am happily flipping switches, tape reels whirring, exporting data for address 
validation.  This is good, I am happy, but ...

Hi John --

I must say I have never done that "dynamic" t-SQL via C# - I guess it should
be doable: using SMO or even SqlCommand's .ExecuteNonQuery(?) it should be
possible to create SPs and UDFs, and then execute them as usual...

BTW, UDFs, which return tables are very often a good substitute for all
kinds of temp tables and dynamic SQL...

I wonder what for all that "dynamism" there? 
Do you have constantly changing database structure?
Do you have constantly changing customer requests, which do not allow you to
create a set of stable parameterized SPs and UDFs, and for small(?) changing
part of queries use LINQ for SQL or ADO.NET EF?

Thank you.

Hi John

As I see it, that would be LINQ and ADO.NET EF (Entity Framework). Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you. Critics tell that this SQL could be long-winded (= not optimized) but what do I care? If it flips 17 or 87 switches does nothing to me as long as the result is fast and precise.

ADO.NET EF is an amazing piece of work. It is not mature but if MS continues to evolve it with the same speed as Silverlight I'm sure it will catch up.

Hello All,

I am running VS 2008 on a powerful machine with loads of resources.  My

app.

However, when I manipulate the Data Context Objects in the AppCode Folder,
the response times are dreadfully, slow.  It takes three to four minutes to
open, edit, save and close one of these objects.

I have tried it on a second machine and the results are similar.

I can edit the Dbml files outside of the solution, but I am not sure whether
that is safe to do so, when I edit them outside the solution (copying and
pasting to another folder and then opening the dbml file from there), they
open instantly.  When I say "safe to do so", does the project file or the
sln file need to be updated with the changes that have been made.  I do get
some warning message about "cannot find web.config, so using the file from
the dbml file instead" which I accepted.

I recall Shamil mentioned that manually editing these within the individual
files is not a good idea, so i guess that he may have been suffering the
same problems as I am, IE so sloooow to open and close.

TIA for an help, if I have not expressed the problem clearly enough, let me
know,

Mark

Hello Mark --

First of all try to switch to FireFox - forget IE while debugging large
ASP.NET apps from within VS....

I  can only note that debugging large ASP.NET applications is a real PITA -
this is why I'm always trying to get out as much as possible BL and DAL code
into separate projects and develop, debug/test them without UI (ASP.NET or
WinForms or WCF)...

And DNN is a "huge ASP.NET" app with a lot of classlibs, which are so
tightly coupled together that there is no way to debug part of them outside
of running DNN instance - with all the consequences - bad luck...

I suppose you can edit DNN's Data Context Objects source code from AppCode
outside of VS (e.g. within notepad) - when the edits are saved then DNN will
restart, that could take a while, quite a while....

A temp solution could be to keep *all* the source code of DNN module's
control within that control's code behind .aspx.cs (.aspx.vb) during
development - when you edit your code there then ASP.NET app will not
restart it will just recompile .aspx and .aspx.cs - so it should work
considerably quicker...

All in all I think DNN custom modules development is a RPITA - one can never
know how much it will finally take for a given project if they will not try
to find a way to debug/ test as much as possible code outside of running
DNN: something like develop a separate ASP.NET application, make it working
and then port it to DNN environmnet...

Be prepared for "crazy debug sessions" (if I'm  not missing something and
there are some "miracle" tools, which simplify DNN custom development
debugging)...

Philosophic note: DNN seems to be a good example that there "are no miracles
in this world" - DNN is a great prototyping tool and CMS, when one has ready
to use DNN modules and skins, and DNN is becoming RPITA when one have to
develop a(n) (advanced) custom module. Rhetoric Question: Why in this world
there couldn't be a "silver-bullet" tool able to support both standard and
custom development with the same ease as DNN does support CMS development?

I guess "Ruby on Rails" could be "what doctor ordered"?...

Or ASP.NET MVC2 Framework?

DNN did grow from a "junky" MS ASP.NET sample code base, and even advanced
developers as DNN Core Development Team members are can't still "convert"
that original "junk" to pearls...

Hopefully they will do that in DNN v.7? - they "just" need to clean-up DNN
huge code base and to implement what is called "Inversion of Control"
(http://martinfowler.com/articles/injection.html) to "untight" DNN Core
classlibs as much as possible...

Please correct me if I'm wrong - in fact I'd be really happy to be wrong
here as I have had to suspend one of the DNN projects, which didn't go
smoothly because of PITA DNN custom modules development experience...

Sorry, Mark, I have no a definitive answer for you here - just some "soap"
and "bubbles" and PITA of my own DNN custom modules development experience,
which I need to find a way to workaround, or quit the idea of DNN custom
development completely as it's too expensive to be true. Still hope I missed
some approaches to simplify this development - I mean ready to use
approaches and tools without long learning curve...

Thank you.

Subject: [dba-VB] Why are my data Context Objects soooo sloooow

Hello All,

I am running VS 2008 on a powerful machine with loads of resources.  My

change a few lines of code and then immediately see the results in the web
app.

However, when I manipulate the Data Context Objects in the AppCode Folder,
the response times are dreadfully, slow.  It takes three to four minutes to
open, edit, save and close one of these objects.

I have tried it on a second machine and the results are similar.

Hello Shamil,

Thank you for your detailed response.

*Browsers*
Some comments, I am actually using Chrome to View my work, but I am not
doing any debugging, in the traditional sense, I code a few lines, click
save and then view the results in Chrome, when I am not happy, I flick back
to VS, change it and continue again.  So, it is true to say, I am not really
debugging, just viewing.  However, I stopped using IE a few years ago, and
since I switched to Chrome, it is the first thing I install on new machines.
 With the exception of the MSDN site, it works perfect for me.


*Slow Data Contexts*
So can I assume that this slowness is simply to be accepted, it is either a)
the way VS2008 usually performs, or b) the way VS2008 performs when data
contexts are involved in a large project such as DNN.  I did not notice any
difference when I copied the code from the wwwroot folder, so I hope that is
not part of the problem.

*DNN Development*
Probably I am not doing real DNN custom programming, but I am currently
building web user controls, and simply saving them, and then creating a
module for DNN and including the web user control on that module.  I know
this is not real DNN programming, but have created about 20 module so far
like this.  DNN gives me, as a script kiddie type programmer, they ability
to do a simple web app, but it manages the users and authentication,
something that I could never program.

IOW, with the exception of a few DNN hooks, I am doing simple programming,
but throwing the results into DNN.


*Free Lunch*
I have to say I agree with you, there are limitations everywhere.  My
appoach is always to keep it as simple as possible until I absolutely know
that I need to make it more complex.



Thanks,

Mark

Hi Mark,

<<<
*Slow Data Contexts*
>>>
What do you mean by that? - editing and saving your DNN Data Context Objects
source code in \AppCode subfolder?
What do you mean by "Dbml"?

<<<
but have created about 20 module so far
like this.
>>>
OK, I have also made 30+ DNN5.x custom modules properly packed etc. - all
very similar to each other but to get the first one was a time-consuming
issue. "Tired" from that. Need a break. Then I maybe will make some more...

Thank you.

Shamil,

As I have discussed in the past, the business is doing the exact same process to many different 
tables.  Because of the size of these tables and the processing involved I find it useful to store 
each table in it's own database.  These are just lists of names, each list comes from a different 
source and is called something by the client, something that makes sense to him.  These lists (a 
table) will always be millions of names / addresses, and often are 50 million or more.  When you 
have 50 million names, the database, with just this one single table will be 10 or 20 gigabytes. 
Once you start processing it can mushroom to 50 gigabytes.  Thus storing a dozen of these tables in 
a single database just doesn't make sense (to me).

Thus I have a dozen different databases.

I have to apply all of these stored procedures to each one of these databases once a month.  Thus 
write the stored procedure such that I can pass in a database name and a table name.  Voila, the SP 
works for all of my databases.  But that means dynamic SQL.  I really don't have an issue with 
dynamic SQL, although I have witnessed first hand the time required for SQL Server to do the 
"compile" - creating the execution plan.  If I run the SP a second time with the same db and table 
name the time to execute drops sharply.

BTW, these lists become the source for "orders" of names.  Each of these orders also are stored in 
its own database, and I have to execute these same (or similar) SPs against each of these orders. 
Over the last 4 years I have perhaps a hundred of these order databases.

This is what I do for this client, create these databases, and apply processes against these 
databases.  The processes are exactly the same across all of the databases, thus having a stored 
procedure that performs some part of that process but can be applied to any of these databases makes 
sense (to me).

I have spent the last five years performing these processes entirely manually, then one by one 
creating a stored procedure to automate one of the steps, then the next step, and the next.  By now 
I have an entire master library with (let me go check) 42 different stored procedures that, taken 
together, automate my work for the client.

THAT is the point of the C# side of things.  Automating the automation so to speak.  Taking these 42 
stored procedures and stringing sets of them together, 7 which perform the output of data to an 
external program for processing, 6 more that get the processed data back in, a half dozen more that 
perform some other processing, another set that do order processing, etc.

This is not a bank, or a company or a call center or a manufacturer, or any of the other "typical" 
SQL Server databases.  It is name / address list processing and creating orders from these lists. 
Really pretty simple but extremely painstaking.  And like anything else we do, I can't be making 
mistakes, it must be done in a specific manner, a specific sequence, EVERY time.

Subject: [dba-VB] Read XML File Using xsd Schema File
Message-ID: <38c884770912020805s570c99e1ia753bf4f81b4d0f7@mail.gmail.com>

To all,

We have been a given what looks to me like a fairly complex XML file, we
have also been given a xsd schema file.  I tried using the SQLXMLBulkLoad
object in VB6 and was getting the error

Schema: relationship expected on 'Company'.

The company that gave us both the files insist that the xsd is correct
(according to my project manager).  I downloaded and installed Stylus Studio
2010, with which I loaded the XML, and then generated my own xsd schame
file.  Tried again and this time get the same error as above, but instead of
'Company' the error was 'Groups'

The VB6 code I am using is as follows:

Dim objBL

Set objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad")
objBL.ConnectionString = "Provider=SQLOLEDB.1;Password=hermes;Persist
Security Info=True;User ID=sa;Initial Catalog=XLTestCD;Data Source=AL-SQL1"


objBL.KeepIdentity = True

objBL.errorlogfile = "C:\XML_StylusStudio\Error.log"

objBL.checkconstraints = True
objBL.xmlfragment = True
objBL.schemagen = True
objBL.sgdroptables = True

objBL.Execute "C:\XML_StylusStudio\newschema.xsd",
"C:\XML_StylusStudio\CDFull_Original.xml"
Set objBl=Nothing

The object of the exercise being that we generate related tables in SQL
Server 2005 of the XML data.

Would be grateful if anyone could help with this (would be happy to send
example XML file and the schema offline), as I haven't got much hair left to
pull out.

Hi John --

Thank you for your reply.

Do you use your different databases for data input, or you also have to
update those different databases' tables?

Shamil,

As I have discussed in the past, the business is doing the exact same
process to many different 
tables.  Because of the size of these tables and the processing involved I
find it useful to store 
each table in it's own database.  These are just lists of names, each list
comes from a different 
source and is called something by the client, something that makes sense to
him.  These lists (a 
table) will always be millions of names / addresses, and often are 50
million or more.  When you 
have 50 million names, the database, with just this one single table will be
10 or 20 gigabytes. 
Once you start processing it can mushroom to 50 gigabytes.  Thus storing a
dozen of these tables in 
a single database just doesn't make sense (to me).

Thus I have a dozen different databases.

I have to apply all of these stored procedures to each one of these
databases once a month.  Thus 
write the stored procedure such that I can pass in a database name and a
table name.  Voila, the SP 
works for all of my databases.  But that means dynamic SQL.  I really don't
have an issue with 
dynamic SQL, although I have witnessed first hand the time required for SQL
Server to do the 
"compile" - creating the execution plan.  If I run the SP a second time with
the same db and table 
name the time to execute drops sharply.

BTW, these lists become the source for "orders" of names.  Each of these
orders also are stored in 
its own database, and I have to execute these same (or similar) SPs against
each of these orders. 
Over the last 4 years I have perhaps a hundred of these order databases.

This is what I do for this client, create these databases, and apply
processes against these 
databases.  The processes are exactly the same across all of the databases,
thus having a stored 
procedure that performs some part of that process but can be applied to any
of these databases makes 
sense (to me).

I have spent the last five years performing these processes entirely
manually, then one by one 
creating a stored procedure to automate one of the steps, then the next
step, and the next.  By now 
I have an entire master library with (let me go check) 42 different stored
procedures that, taken 
together, automate my work for the client.

THAT is the point of the C# side of things.  Automating the automation so to
speak.  Taking these 42 
stored procedures and stringing sets of them together, 7 which perform the
output of data to an 
external program for processing, 6 more that get the processed data back in,
a half dozen more that 
perform some other processing, another set that do order processing, etc.

This is not a bank, or a company or a call center or a manufacturer, or any
of the other "typical" 
SQL Server databases.  It is name / address list processing and creating
orders from these lists. 
Really pretty simple but extremely painstaking.  And like anything else we
do, I can't be making 
mistakes, it must be done in a specific manner, a specific sequence, EVERY
time.

Hi John et al

Don't forget LINQPad.

Hi John

As I see it, that would be LINQ and ADO.NET EF (Entity Framework). Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you. Critics tell that this SQL could be long-winded (= not optimized) but what do I care? If it flips 17 or 87 switches does nothing to me as long as the result is fast and precise.

ADO.NET EF is an amazing piece of work. It is not mature but if MS continues to evolve it with the same speed as Silverlight I'm sure it will catch up.

As previously mentioned, over the last couple of years I have built up a set of stored procedures 
which perform TSQL.  I then run sets of these stored procedures to perform processes.  The TSQL is 
always dynamic.

As an example a stored procedure might build a table, with boilerplate field names and data types, 
but a passed in database and table name.  Inside of the stored procedure I build up the correct SQL 
to create the table in the database specified, with the name specified.  Another stored procedure 
might create in index, with boilerplate field names, but a passed in database and table name.  Again 
the stored procedure builds up the TSQL statement to create the index in the correct db and table.

I already have these stored procedures debugged and working and have been using them in sets to 
perform "big picture processes" for quite some time, but the whole "execute a stored procedure" 
using a command object, parameter objects in a parameter array, interpreting the parameters etc just 
seems so... 1950s.  I feel like I am flipping switches on the front panel of a computer in a 50s 
sci-fi movie as a tape reel spins madly in the background.

Now that I am moving to C# I am wondering if this is required any more.  Can C# execute TSQL 
directly somehow?  Can I assemble this boiler plate plus database / table kind of thing into a TSQL 
statement directly in C# and then somehow tell SQL Server to execute that TSQL?  I understand the 
"SQL optimization" thing but it seems like (not sure here) that because the TSQL is dynamically 
constructed in the stored procedure, the whole "optimization" thing goes right out the window.  If I 
can execute TSQL directly from C#, what can I get back?  Rows affected?  Error codes?  And how?

As it stands I am happily flipping switches, tape reels whirring, exporting data for address 
validation.  This is good, I am happy, but ...

Shamil,

I receive lists of names in CSV or fixed width files.  I import those into SQL Server, creating a 
PKID in the process.  I then have to export the PKID plus the name / address monthly for address 
validation.  Once validated, I have to import the data back in.  This is the monthly process. 
Approximately 1% of all the people on any given list move each month.  So I have to go back in to 
the original list and update 1% of the addresses, or simply swap out the new list (table) for the 
old.  There is never any manual processing of individual names inside of these lists, IOW people 
never look at them, modify them, add new ones, delete address or anything like that.  The list is 
"stable" in that regard.

These lists become the source for orders of names.  Orders are a whole 'nother process, but also use 
SPs to do their thing.

John --

Have you tried to use MS SQL database filegroups and partitioned tables &
views?

http://msdn.microsoft.com/en-us/library/ms345146(SQL.90).aspx

With them I suppose only initial import/insert of data have to be
parameterized with table name, and the rest can be done without any dynamic
T-SQL. Please correct me if I'm wrong.

Please note I'm not trying to "force" you to change your current working
solution - just wondering is there a legal way to solve your task without
dynamic T-SQL...

Shamil,

I have not.

All of that is rather esoteric stuff for a non DBA.  My job is processing data, and that is only a 
small part of my job, i.e. this is only one of many clients, and the only one that needs this kind 
of SQL Server stuff.

As I have said many times, if my job was to go into a company every day and play DBA then I would 
learn many more things SQL Server related.  As things stand I learn just enough to make things work, 
and a LITTLE extra in search of efficiency.  It is certainly not that I don't want to, I just don't 
have the time.

In the end I find the method I use comfortable from many angles.  I have to do some things that 
require creating views, other "processing" tables and so forth.  It really just works (for me) to do 
things this way, have separate databases to hold all of the "junk" associated with each list.  Kind 
of the old "encapsulation" thing.

Your suggestion would of course end up with all tables inside of a single "database", and as such 
the need for the Database parameter would go away but I still have to do the same thing to many 
different tables.

Again, could this be done by one of the experts on the SQL Server list.  Probably!  Will I ever get 
there?  Uhhhh doubtful.

Hi John --

OK. Don't break it with implementation of other approaches if it works...

Just for the future projects - I suppose (I might be missing something as I
do not have that experience but I plan to try, maybe within our
Northwind.NET project) this partitioning stuff is just practical for the
tasks as you do (similar stuff was available for non-relational DBMSs in the
end of 70-es/beginning of 80ies, and for Oracle it's available for years now
AFAIHH), and this stuff doesn't take that much time to learn (one day?)  and
use (a few short reusable T-SQL scripts?) that it would  take to program and
to test and to support dynamic T-SQ: for many SPs and UDFs...

Thank you.

Subject: Re: [dba-VB] C# - Direct data manipulation

Shamil,

I have not.

All of that is rather esoteric stuff for a non DBA.  My job is processing
data, and that is only a 
small part of my job, i.e. this is only one of many clients, and the only
one that needs this kind 
of SQL Server stuff.

As I have said many times, if my job was to go into a company every day and
play DBA then I would 
learn many more things SQL Server related.  As things stand I learn just
enough to make things work, 
and a LITTLE extra in search of efficiency.  It is certainly not that I
don't want to, I just don't 
have the time.

In the end I find the method I use comfortable from many angles.  I have to
do some things that 
require creating views, other "processing" tables and so forth.  It really
just works (for me) to do 
things this way, have separate databases to hold all of the "junk"
associated with each list.  Kind 
of the old "encapsulation" thing.

Your suggestion would of course end up with all tables inside of a single
"database", and as such 
the need for the Database parameter would go away but I still have to do the
same thing to many 
different tables.

Again, could this be done by one of the experts on the SQL Server list.
Probably!  Will I ever get 
there?  Uhhhh doubtful.

Hi Dan and Doug,

If that stats will help you to quote and to plan your projects, please write
a short note to be posted there (myself or Gustav can post it)

http://northwind.codeplex.com/Thread/View.aspx?ThreadId=54924

This project is currently in suspended state, and good feedback might help
to plan and to implement some useful follow-ups.

Thank you.

Hello Shamil,

In VS2008, when I create a folder in app_Code, and then create a new Linq to
SQL Class is it assigned the extention of dbml, default name is
DataClasses.dbml

It is these classes that are sooo slooow to do anything with.  I timed the
time it takes to just click create, drop a table onto the design surface,
and then click save.  It is taking 4 minutes to do that, so when I needed 20
- 25 objects or so, I have to sit like a donkey and click for almost two
hours.

It still takes four minutes to open and edit one.

A PITA for sure.

If I open the class as a standalone file, I can operate with
instant performance, but it does not play well with the project/ solution.

I have to say, I wish I knew more about these data classes and how they
really should be used in real world applications.

Thanks

Mark

Hello Mark --

OK, I suppose you can create custom DLL(s) working with LINQ to SQL in a
solution outside of your custom DNN solution, and then just use your custom
DLL within custom DNN solution - your LINQ to SQL objects from DLL should be
public and this DLL should also have its own config file...

I have done something like that but with POCO-objects
(http://en.wikipedia.org/wiki/Plain_Old_CLR_Object), which I used as
ObjectDataSources for web forms within DNN custom solutions' custom
modules...

Thank you.

Hello Shamil,

I guess this is an option for me, but to be honest, it will probably more
easier  for me to take the delay of waiting that attempt to manage the
additional layer of complexity.  As with all things in life, I suppose if I
take the time to review this, it will save me time, but I am afraid to spend
a day on it only to save myself a few minutes a few times a day.

Thanks any way for the suggestion,

Mark

Create an xml file called UserSettings (or whatever) and store each value in a node in that.  Then all you have to do is read them back when you need them.  We use several of these, one called OLEDBSettings.xml that looks like this: 

  <?xml version="1.0" standalone="yes" ?> 
- <NewDataSet>
- <connection>
  <dbtype>0</dbtype> 
  <provider>Microsoft.Jet.OLEDB.4.0</provider> 
  <datasource>C:\Documents and Settings\All Users\Application Data\Infostat\RIMDrill\5\RIMDrillData.mdb</datasource> 
  <userid>RIMUser</userid> 
  <password /> 
  <initialcatalog /> 
  <trusted>false</trusted> 
  </connection>
- <connection>
  <dbtype>1</dbtype> 
  <provider>sqloledb</provider> 
  <datasource>infoserver</datasource> 
  <userid /> 
  <password /> 
  <initialcatalog>RIMDrillDataSQL</initialcatalog> 
  <trusted>true</trusted> 
  </connection>
  </NewDataSet>

We actually have a file like this for each application and it lives in the application folder.  This is just to give you an idea, not a how to.   We have a class that wraps this in our apps and uses this kind of routine to read it.  I leave it up to you to translate to C#.

    Shared ds As DataSet
    Shared _connectionString As String

    Shared _xmlPath As String = "OLEDBSettings.xml"         'default to xml file in apppath

   Private Shared Sub ReadSettingsFile()
        If IO.File.Exists(_xmlPath) Then
            Call CreateSchema()
            ds.ReadXml(_xmlPath)
            Call DecryptPassword()
            _connectionString = GetConnectionString()
        Else
            If ds.Tables(0).Rows.Count = 0 Then
                'placeholder for jet settings
                Dim row As DataRow = ds.Tables(0).NewRow
                row("dbtype") = 0
                row("provider") = "Microsoft.Jet.OLEDB.4.0"
                ds.Tables(0).Rows.Add(row)

                'placeholder for sql settings
                row = ds.Tables(0).NewRow
                row("dbtype") = 1
                row("provider") = "sqloledb"
                ds.Tables(0).Rows.Add(row)
            End If
        End If
    End Sub

  Private Shared Sub CreateSchema()
        ds = New DataSet
        Dim table As New DataTable("connection")
        table.Columns.Add("dbtype", GetType(Integer))
        table.Columns.Add("provider", GetType(String))
        table.Columns.Add("datasource", GetType(String))
        table.Columns.Add("userid", GetType(String))
        table.Columns.Add("password", GetType(String))
        table.Columns.Add("initialcatalog", GetType(String))
        table.Columns.Add("trusted", GetType(Boolean))
        table.PrimaryKey = New DataColumn() {table.Columns("dbtype")}

Hi Charlotte,

I see this as useful, but,
If you need a complex setting structure why not just create a
'MySettings' class and serialise or deserialise it as needed?
I think John has already worked with the Serializable attribute.
Am I missing something?

Cheers

Michael M

Create an xml file called UserSettings (or whatever) and store each
value in a node in that.  Then all you have to do is read them back when
you need them.  We use several of these, one called OLEDBSettings.xml
that looks like this: 

  <?xml version="1.0" standalone="yes" ?> 
- <NewDataSet>
- <connection>
  <dbtype>0</dbtype> 
  <provider>Microsoft.Jet.OLEDB.4.0</provider> 
  <datasource>C:\Documents and Settings\All Users\Application
Data\Infostat\RIMDrill\5\RIMDrillData.mdb</datasource> 
  <userid>RIMUser</userid> 
  <password /> 
  <initialcatalog /> 
  <trusted>false</trusted> 
  </connection>
- <connection>
  <dbtype>1</dbtype> 
  <provider>sqloledb</provider> 
  <datasource>infoserver</datasource> 
  <userid /> 
  <password /> 
  <initialcatalog>RIMDrillDataSQL</initialcatalog> 
  <trusted>true</trusted> 
  </connection>
  </NewDataSet>

We actually have a file like this for each application and it lives in
the application folder.  This is just to give you an idea, not a how to.
We have a class that wraps this in our apps and uses this kind of
routine to read it.  I leave it up to you to translate to C#.

    Shared ds As DataSet
    Shared _connectionString As String

    Shared _xmlPath As String = "OLEDBSettings.xml"         'default to
xml file in apppath

   Private Shared Sub ReadSettingsFile()
        If IO.File.Exists(_xmlPath) Then
            Call CreateSchema()
            ds.ReadXml(_xmlPath)
            Call DecryptPassword()
            _connectionString = GetConnectionString()
        Else
            If ds.Tables(0).Rows.Count = 0 Then
                'placeholder for jet settings
                Dim row As DataRow = ds.Tables(0).NewRow
                row("dbtype") = 0
                row("provider") = "Microsoft.Jet.OLEDB.4.0"
                ds.Tables(0).Rows.Add(row)

                'placeholder for sql settings
                row = ds.Tables(0).NewRow
                row("dbtype") = 1
                row("provider") = "sqloledb"
                ds.Tables(0).Rows.Add(row)
            End If
        End If
    End Sub

  Private Shared Sub CreateSchema()
        ds = New DataSet
        Dim table As New DataTable("connection")
        table.Columns.Add("dbtype", GetType(Integer))
        table.Columns.Add("provider", GetType(String))
        table.Columns.Add("datasource", GetType(String))
        table.Columns.Add("userid", GetType(String))
        table.Columns.Add("password", GetType(String))
        table.Columns.Add("initialcatalog", GetType(String))
        table.Columns.Add("trusted", GetType(Boolean))
        table.PrimaryKey = New DataColumn() {table.Columns("dbtype")}

I want to create application settings for things like the server
instance that the program will bang on, the name of my database that I
save my custom UDFs and SPs in etc.  It is trivial to get there in the
interface but Google is not my friend tonight in discovering how to
access / modify them through code.

Anybody?

Hi John

Yes and no. I used an old version for some time but the current version is more powerful.

Please note that it comes with all the examples from his book, and even without the book this is a great why to get your hands on LINQ as the code is "live" - no need to copy and paste, it is right there for you try out at once.

Hi John et all

Further to the notes below on Joseph Albahari's LINQPad, it contains a link to download all the example code from "LINQ in Action".
Also, it has a link to this amazing demo of the power of LINQ:

http://blogs.msdn.com/lukeh/archive/2007/03/19/using-linq-to-solve-puzzles.aspx 

It's a true eye-opener and a good example showing that the scope of LINQ is much wider than "normal" database querying.

The code is included in LINQPad when downloaded, ready for you to play with at:

  Tab Samples, 
  C# 3.0 in a Nutshell, Chapter 9 - LINQ Operators, Joining, Extra - Weights Puzzle. 

It's Friday and soon weekend!

Message-ID: <38c884770912040419xdc61c66y2c315b820cd6fb09@mail.gmail.com>

To all,

We have been a given what looks to me like a fairly complex XML file, we
have also been given a xsd schema file.  I tried using the SQLXMLBulkLoad
object in VB6 and was getting the error

Schema: relationship expected on 'Company'.

The company that gave us both the files insist that the xsd is correct
(according to my project manager).  I downloaded and installed Stylus Studio
2010, with which I loaded the XML, and then generated my own xsd schame
file.  Tried again and this time get the same error as above, but instead of
'Company' the error was 'Groups'

The VB6 code I am using is as follows:

Dim objBL

Set objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad")
objBL.ConnectionString = "Provider=SQLOLEDB.1;Password=hermes;Persist
Security Info=True;User ID=sa;Initial Catalog=XLTestCD;Data Source=AL-SQL1"


objBL.KeepIdentity = True

objBL.errorlogfile = "C:\XML_StylusStudio\Error.log"

objBL.checkconstraints = True
objBL.xmlfragment = True
objBL.schemagen = True
objBL.sgdroptables = True

objBL.Execute "C:\XML_StylusStudio\newschema.xsd",
"C:\XML_StylusStudio\CDFull_Original.xml"
Set objBl=Nothing

The object of the exercise being that we generate related tables in SQL
Server 2005 of the XML data.

Would be grateful if anyone could help with this (would be happy to send
example XML file and the schema offline), as I haven't got much hair left to
pull out.

Thanks in advance for any help on this.

Hi John

Oh, I misunderstood you.
Not until recently. Skipping the SQLCommand low-level stuff completely, I've used datatables with in-line SQL queries (to avoid designing T-SQL and special views - Shamil mobbed me for that choice!) and I have been busy learning just these - so one step further, no thanks. Also, I had a hard time grasping the lambda expressions and syntax and still feel I have a lot to learn. Yes, you can use LINQ without lambda, but that seems like LINQ without an arm and a leg. But - for anything else than some special cases like perhaps your cases - I'm confident LINQ is the route to follow.

I have to say that as a developer of a higher level language, I can see where avoiding TSQL would be 
  something we would try to do.  While I understand that SQL Server can be integrated into and used 
straight from the VS environment, most of us come at it from the built-in editor which frankly 
sucks.  And I mean REALLY BADLY sucks, no apologies to our admin friends.  I guess I have been doing 
SP development for a couple of years now and I still hate the built-in editor.  And yet... that is 
what I use.

IMHO this is an area where MS has fallen down on the job.  If this integration thing is so darned 
simple, then MS should push education, seminars, books, education, education to get us working in VS 
to run (program) SQL Server.  From a development perspective, and that is what SPs and UDF are after 
all, SQL Server should just be a tool used to manipulate data, NOT a dev environment.

Over the last month I have found two APIs that allow C# to do a ton of stuff directly in SQL Server. 
  WAY COOL stuff, but you would think it was porn the way you don't see it in the mainstream.  These 
APIs allow you to manipulate SQL server the same way you can manipulate any other object - create, 
delete, observe, modify, manipulate anything in SQL Server - straight from VS.  But where are the 
forums, the blogs, the developer excitement?  It appears to me that there is a very real "here is 
your database" aimed at the developers who use SQL Server, and the admins just do things the way 
they always have for the last 20 years.  And they buy tools from the RedGates of the world who 
undoubtedly do salivate over these new APIs.

Just my humble opinion.

Charlotte,

My question really is how do I get at the settings area of the project, and why would I not use that 
instead of this xml thing of yours?  At least in this specific case, I am writing code for myself, 
not distribution.

Hi John

One reason could be that many web developers know little about database design, thus they are being forced to leave that to a DBA. A chief developer once told at a tech meeting I attended, that they operated with the concept "scared of the database" meaning that the web developers should just be presented with ready-made views because SQL to these was like black magic.

mobbed me for that choice!)

I have to say that as a developer of a higher level language, I can see where avoiding TSQL would be 
  something we would try to do.  While I understand that SQL Server can be integrated into and used 
straight from the VS environment, most of us come at it from the built-in editor which frankly 
sucks.  And I mean REALLY BADLY sucks, no apologies to our admin friends.  I guess I have been doing 
SP development for a couple of years now and I still hate the built-in editor.  And yet... that is 
what I use.

IMHO this is an area where MS has fallen down on the job.  If this integration thing is so darned 
simple, then MS should push education, seminars, books, education, education to get us working in VS 
to run (program) SQL Server.  From a development perspective, and that is what SPs and UDF are after 
all, SQL Server should just be a tool used to manipulate data, NOT a dev environment.

Over the last month I have found two APIs that allow C# to do a ton of stuff directly in SQL Server. 
  WAY COOL stuff, but you would think it was porn the way you don't see it in the mainstream.  These 
APIs allow you to manipulate SQL server the same way you can manipulate any other object - create, 
delete, observe, modify, manipulate anything in SQL Server - straight from VS.  But where are the 
forums, the blogs, the developer excitement?  It appears to me that there is a very real "here is 
your database" aimed at the developers who use SQL Server, and the admins just do things the way 
they always have for the last 20 years.  And they buy tools from the RedGates of the world who 
undoubtedly do salivate over these new APIs.

Just my humble opinion.

Skipping the SQLCommand low-level stuff completely, I've used datatables with in-line SQL queries (to avoid designing T-SQL and special views - Shamil mobbed me for that choice!) and I have been busy learning just these - so one step further, no thanks. Also, I had a hard time grasping the lambda expressions and syntax and still feel I have a lot to learn. Yes, you can use LINQ without lambda, but that seems like LINQ without an arm and a leg. But - for anything else than some special cases like perhaps your cases - I'm confident LINQ is the route to follow.

I actually think that is a good thing, developers who just use data shouldn't need to be learning 
SQL Server to get their data.

That is really not the audience I am addressing however.  IMHO the built-in editor of SQL Server 
should either be removed entirely or at least brought into the current century.  It is notepad with 
pretty colors.  How many millions of man hours have been wasted trying to track down errors when the 
only error message presented was "error near (insert some unrelated thing here)".  Why bother even 
throwing up an error like that, and that is 99.9% of the errors I have EVER seen in two years 
working with SQL Server.

Notepad, with pretty colors.

For all of the rude comments us Access developers get about Access being "a toy", the code editor in 
Access is in a complete other galaxy from the code editor in SQL Server.  SQL Server editor looks 
like it was designed in 1986 and never upgraded.

Of course with the "real men don't use code editors" mentality of the DBA side of the fence I can 
see why MS doesn't bother spending time on this.

Someday I really am going to have to figure out how to use VS to run / debug my SPs and stuff.  To 
me VS just seems over-the-top complex for the level of stuff I am trying to do.  An Access type of 
code editor would be just the right level of convenience and capability - built right into SSMS.

Hi John

LINQPad does pure SQL too, though not with IntelliSense, and error messages seem to be those from SQL Server.

OK, then I don't understand the question.  What do you mean about the settings "area" of the project?

Charlotte,

My question really is how do I get at the settings area of the project, and why would I not use that instead of this xml thing of yours?  At least in this specific case, I am writing code for myself, not distribution.

Under the project is a properties object.  Double click that and an entire multi-tabbed dialog opens.

Click the settings tab.  There you will see a form where you can enter name, type, scope, value.

As far as I can tell this is a place where I (the developer) can create settings that my program 
will use and manipulate, settings (for example) to tell my program the name of the SQL Server 
instance to use in a connection string, the name of my control database where I store my stored 
procedures and UDFs.  Stuff like that.  Stuff that I am currently hard coding, but which really 
should be in a settings tab so that I don't have to remember where that constant is in code, I can 
just go to the settings tab to change.

My expectation is that there is an object somewhere in the .net namespace that allows you to do 
something like "Something.Somethingelse.Settings["MyServerName"]...." to access these things.

I expect to be able to create new ones, edit existing ones, delete them etc from a .Net object.  I 
am looking for that .Net syntax that allows me to do this from code.

Hi John,

You can access those properties using:

Properties.Settings.Default.{{PropertyName}}

Or

{{Root Namespace}}.Properties.Settings.Default.{{PropertyName}}

Hi John

Shamil is right, but that method is for reading only.
Please note that the Properties' collection object is read-only, thus it takes quite a few steps to add a property:

http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/c52b4fc6-66be-44ce-8a65-ab548f6f4f04

I have not used this as I haven't had any need to add properties on the fly. Reading and writing was fine for me, and new properties I added manually.

You may find it much easier and perhaps more convenient to just have a dataset which you read and write from/to an XML-file. I've posted code for this before.

Hi Gustav,

You can set 

Properties.Settings.Default.{{PropertyName}} = {{SomeValue}};

and save settings having "User" scope:

Properties.Settings.Default.Save();    

And they are saved not in {{ApplicationExecutableFileName}}.config, which
you deliver with you app's executable but anywhere else on your system -
probably somewhere in user's Application Settings - standard windows folder.
I have never had time to find out where settings are saved. Anybody?

Recap:

- settings are loaded from {{ApplicationExecutableFileName}}.config when you
deliver you application, and it runs first time;
- as soon as you save "User" scope settings they are saved in and loaded
from {{UnknownPlace}};
- if you move your application files into another folder on the same system
the settings are again loaded on first run from
{{ApplicationExecutableFileName}};
- ...

That looks confusing a bit but it's how it works...

You can click "Learn more about application settings..." on top right of
VS2008 application settings window available by Solution Explorer -> Project
name -> Right-Click -> Settings...

But if you wanted to have rather complicated structure of your application
settings file then better use your own custom XML files, which can be loaded
from/saved to files many ways without almost any coding...

Thank you.

Hi Shamil

Yes, but is PropertyName appended and saved if it didn't exist?

Isn't the data saved under the user profile somewhere in AppData? I haven't look closer at this though.

Hi Gustav,

You can set 

Properties.Settings.Default.{{PropertyName}} = {{SomeValue}};

and save settings having "User" scope:

Properties.Settings.Default.Save();    

And they are saved not in {{ApplicationExecutableFileName}}.config, which you deliver with you app's executable but anywhere else on your system -
probably somewhere in user's Application Settings - standard windows folder.
I have never had time to find out where settings are saved. Anybody?

Recap:

- settings are loaded from {{ApplicationExecutableFileName}}.config when you deliver you application, and it runs first time;
- as soon as you save "User" scope settings they are saved in and loaded from {{UnknownPlace}};
- if you move your application files into another folder on the same system the settings are again loaded on first run from {{ApplicationExecutableFileName}};
- ...

That looks confusing a bit but it's how it works...

You can click "Learn more about application settings..." on top right of VS2008 application settings window available by Solution Explorer -> Project
name -> Right-Click -> Settings...

But if you wanted to have rather complicated structure of your application settings file then better use your own custom XML files, which can be loaded
from/saved to files many ways without almost any coding...

Thank you.

Hi John

Shamil is right, but that method is for reading only.
Please note that the Properties' collection object is read-only, thus it
takes quite a few steps to add a property:

http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/c52b4fc6- 
66be-44ce-8a65-ab548f6f4f04

I have not used this as I haven't had any need to add properties on the fly.
Reading and writing was fine for me, and new properties I added manually.

You may find it much easier and perhaps more convenient to just have a
dataset which you read and write from/to an XML-file. I've posted code for
this before.

Under the project is a properties object.  Double click that and an entire multi-tabbed dialog opens.

Click the settings tab.  There you will see a form where you can enter name, type, scope, value.

As far as I can tell this is a place where I (the developer) can create settings that my program 
will use and manipulate, settings (for example) to tell my program the name of the SQL Server

No, PropertyName can't be appended and saved if it doesn't exist as they are
compile-time (early) bound - but JC asked exactly about existing properties
defined in VS2008 project settings, and they can be changed and saved if
they have "User" scope.

Yes, I guess they are saved somewhere in AppData but I do not know where...

Hi Gustav and all,

JC original request was "to access/modify" application settings AFAIU:
<<<
I want to create application settings for things like the server instance
that the program will bang on, the name of my database that I save my custom
UDFs and SPs in etc.  It is trivial to get there in the interface but Google
is not my friend tonight in discovering how to access / modify them through
code.

Hi Shamil

Well, much less hard-core than I had expected, indeed not a coding session but with a good perspective.
However, he came a long way describing and demonstrating many new features of VS2010, MVC and Silverlight. Also LINQ and ADO.NET EF seems to be mainstream. And, of course, much warmly promoting of Windows Azure which works very well together with VS, indeed with the new "local Azure" - a local simulator of Azure you can use during development so no live hosting is needed - much like the local web server that simulates IIS.

Very cool is the new GUI designer for Silverlight UI design. VS2010 is brushed up quite a lot with better support for multi-monitor use, improved IntelliSense and editing features in the code editor - everything is aimed at faster development with firm focus on you, the developer, very different from Access.
Further, the Team Foundation edition is now useful for single developers too, with unit testing, versioning etc. etc. However, I expect that to be available at a "corporate" charge only (beyond my budget), but let's see.

He promised to mail us links to the complete session and much more. I can post these here when they arrive.
If you or anyone else have questions to specific topics, Scott Guthrie may have touched, please ask.

global::WindowsFormsApplication1.Properties.Settings.Default.TestSetting
= "New Value";
 
global::WindowsFormsApplication1.Properties.Settings.Default.Save ( );

cheers

Michael M

I want to create application settings for things like the server
instance that the program will bang 
on, the name of my database that I save my custom UDFs and SPs in etc.
It is trivial to get there 
in the interface but Google is not my friend tonight in discovering how
to access / modify them 
through code.

Anybody?

Hi Shamil

Well, much less hard-core than I had expected, indeed not a coding session
but with a good perspective.
However, he came a long way describing and demonstrating many new features
of VS2010, MVC and Silverlight. Also LINQ and ADO.NET EF seems to be
mainstream. And, of course, much warmly promoting of Windows Azure which
works very well together with VS, indeed with the new "local Azure" - a
local simulator of Azure you can use during development so no live hosting
is needed - much like the local web server that simulates IIS.

Very cool is the new GUI designer for Silverlight UI design. VS2010 is
brushed up quite a lot with better support for multi-monitor use, improved
IntelliSense and editing features in the code editor - everything is aimed
at faster development with firm focus on you, the developer, very different
from Access.
Further, the Team Foundation edition is now useful for single developers
too, with unit testing, versioning etc. etc. However, I expect that to be
available at a "corporate" charge only (beyond my budget), but let's see.

He promised to mail us links to the complete session and much more. I can
post these here when they arrive.
If you or anyone else have questions to specific topics, Scott Guthrie may
have touched, please ask.

OK, I am trying to reference

Properties.Settings.Default["ServerName"].ToString() and get the error

'System.Windows.Forms.PropertyStore' does not contain a definition for 'Settings' and no extension 
method 'Settings' accepting a first argument of type 'System.Windows.Forms.PropertyStore' could be 
found (are you missing a using directive or an assembly reference?)

OK, it appears that each project has its own set of properties.  If I set the same property in the 
current project's property set then

Properties.Settings.Default["ServerName"].ToString()

works just fine.

But that is not the behavior I want.  I need a SOLUTION property set, which appears to not exist? 
Which perhaps would explain why those who have done this before roll their own?

Does anyone have code to do this so I don't have to roll my own (a.k.a. reinvent the wheel) too?

Hi John

The file containing the settings is app.config.

To hold "global" settings you could create a small project with just this file and reference it from any other project.

My understanding of Properties.Settings is that settings must be by User
in order to be saved and the xml file will reside in the Local 
Setting/Applications
directory under the user's My Documents folder.

In that case, all projects under a solution could read a single xml file.

We decided to use cryptographic services for the i/o of the xml by
using an internal static class that reads/writes to a string collection
using methods we created like bof, eof, movefirst, addnew, etc.

Hi John --

For solution you can select one of the projects to be used to handle
settings.
That project is usually a core(utility/generic/settings) class library.
Then if you wish you can additionally wrap 

Properties.Settings.Default...

for every/most of the settings into your custom global (Solution scope)
properties' wrappers. Such wrapping makes your referencing projects
independent on actual implementation of handling of application settings.
When that done and works OK you can go and "reinvent the wheel" if needed
without any changes in referencing projects...

OK, it appears that each project has its own set of properties.  If I set
the same property in the 
current project's property set then

Properties.Settings.Default["ServerName"].ToString()

works just fine.

But that is not the behavior I want.  I need a SOLUTION property set, which
appears to not exist? 
Which perhaps would explain why those who have done this before roll their
own?

Does anyone have code to do this so I don't have to roll my own (a.k.a.
reinvent the wheel) too?

Subject: [dba-VB] C# - Thoughts on my methods
Message-ID: <4B1FC705.9010902@colbyconsulting.com>

As a consultant in a home office I work in total isolation except for this email group.  So I need 
your input, to keep me sane and to keep me on the right path.  I would like your thoughts on what I 
am doing and what I am intending to do.

As you know, I have "the database from hell", for which I am developing an application to allow me 
to manipulate the various pieces from an application interface rather than directly from stored 
procedures and the SSMS or from Access, which is what I have done to this point.  With C# I am able 
to do more than I was able from Access, including getting back output parameters from stored 
procedures.  So... my process so far.

First off, I am developing the overall application as a set of child projects inside of the 
application.  The main application opens a form with a menu, and that menu takes me to forms in the 
child projects to perform pieces of the application.  For example I have a database backup project 
where I can backup and restore specific databases or groups of databases.  I have an Accuzip project 
where I can export CSV files to and import resulting CSV files from the external Accuzip program.  I 
have an Orders project where I can create and manipulate the orders I create for the client.

Each child project is physically located underneath the main application directory.  In order to 
reference (open) the forms in the child projects, I have to set a reference to that project and I 
have to set a using statement in the form.  I still do not understand what these two pieces do.  Why 
do I have to set a reference and a using?  I assume you cannot set a using statement unless the 
project references the library (or project)?

I also don't understand why some objects in a referenced project class can be seen but others 
cannot.  IOW I can use one class in a namespace as a type to dimension an object, but another class 
in the same namespace is not visible, cannot be so used.

I don't understand a whole ton of things of this nature and I have to say that the whole "break into 
projects" idea is turning out to be more work than it might be worth.

Any comments on this email will be much appreciated.

Subject: [dba-VB] threading
Message-ID: <4B1FF708.1040700@colbyconsulting.com>

As mentioned in previous emails, I am developing an application to manage all of the tasks for the 
DBFH.  This includes Backing up databases, creating orders, transferring data between an external 
app etc.  I am trying to determine how to thread this app such that if I start a process exporting 
data to Accuzip, I could have another process importing data from Accuzip, and also be working on an 
order.

As things currently stand, each of these tasks is a project and each project has its own forms and 
classes, and anything else necessary for that task.  I really do want to be able to do multiple 
things like this at the same time.  Exporting data to Accuzip can take overnight, and actually 
consists of an export and a matching import process.  It makes perfect sense (to me) to have threads 
doing this kind of thing, and allow me to go back to the main application and do something else.

But at what level would I use a thread?  Would I use a thread to open the form that performs the AZ 
process?  This would allow me to get that started and immediately go back to the main app and open 
another form (using a new thread?) to start processing an order.

Or would the form open and the button on the form start a thread that executes the process?  If a 
form starts a thread, that allows the user (me) to do other things in that form potentially changing 
to a new directory or selecting a different database.  Do you disable all controls on a form when a 
thread starts?  I never had to think about this in VBA and it is all rather confusing.

Why not have several (FE) applications if they are so independent? - all

Hi John,

Have a look for DotNetNuke sources - they have free sources for
zipping/unzipping.
Those sources are used in core DNN functionality (modules setup) - IOW they
tested well, they are stable and thry work very well.

Hi John --

In fact this is easy (please correct me if I'm wrong):

- just reference your child projects from your main project and if you have
(sub-)child projects then reference them from child projects; you can also
reference child-child-(nephew) projects from parent projects etc... - just
avoid having circular references...

All that is very similar to MS Access/VBA references but unlike in MS
Access/VBA in .NET solutions this referencing always work without any
glitches whatever size your solutions are - tens of projects, thousands of
customer classes - no problems, no GPFs of Visual Studio (well, for ASP.NET
and WPF solutions you can have GPFs but even in that case you'll have all
your sources preserved).... 

<<<
I also don't understand why some objects in a referenced project class can
be seen but others 
cannot.  
>>>
That should be your problem/issue: in VS2008 (Prof) you can always try to
hint VS asking to "resolve" undefined class name, enum, global var - right
click -> Resolve... - if it can't do that - you can always do that manually
- but it may be needed to have some custom classes "shuffled" between your
projects...

<<<
the whole "break into 
projects" idea is turning out to be more work than it might be worth.
>>>
John, it will pay itself back very quickly - just be patient - I'd guess
(based on your software development experience) it will need max one week
(in total) of your time to spend mastering that multi-project solutions -
and when you're there - only outer space will be your limitation...

Just create a very simple sample solution with several projects and try to
play with it setting references, moving custom classes from one project to
the other, changing namespaces, and using directives... it's really easy -
imagine hierarchical catalog where child entries can be referenced/accessed
from parent ones, but where sibling entries aren't aware of each other...
(if only they do not inherit from the same parent entries...) 

Thank you.

I have to point out that it is exceptionally easy to create circular references when the projects are set up like this.  That's why in our apps we keep all the forms in a project, all the reports in a project, etc.  Of course, if we were using libraries rather than projects under the solution, it would be different.  But this way, it can get messy fast.

Just create a very simple sample solution with several projects and try to play with it setting references, moving custom classes from one project to the other, changing namespaces, and using directives... it's really easy - imagine hierarchical catalog where child entries can be referenced/accessed from parent ones, but where sibling entries aren't aware of each other...

You can roll your own using J# from within VS.  Idid that originally and it only takes minor translation to put it into C# or VB.  That said, we currently use Xceed.

Subject: [dba-VB] Ajax application problem
Message-ID: <3262DDC894CA427DB254732FCE5E70AF@VOSTRO>

Hi all,


I have problems putting an ajax application on a production server.

The application consists of an aspx page that keeps the javascript code.
This code talks with C# page methods to access Web services and interact with the database.

For example the first thing the user has to do is fill in login and password fields and click on the btnLogin.

Then the code execute the following command:
PageMethods.GetUser(user, onGetUserSuccess, onGetUserError);

with user being an array containing username and password. The C# GetUser webmethod returns its response to the onGetUserSuccess callback function.

The application runs ok on my dev pc.

I installed it on the production server, copying the aspx file, web.config file and the binary files.

When I run it, I get an error message, something like error during the handling of your request.(freely translated from french!!)

This error is displayed into a textbox by the onGetUserError callback function. 
I put an error trapping withing the webmethod, but its error message is not returned, leading me to think that this webmethod is not "entered".
Therefore the javascript code is running ok, but the call to the webmethod is failing.

I guess I missed to copy something like a javascript file from the framework, or something else.

Do you have any kind of experience in this regard?

NB: I also checked that the asp framework is of version 2.0 on the server, it's ok.

TIA,

Philippe Pons

Hi Charlotte --

Yes, it's easy to create cross-refs, and it's (usually) easy to solve
cross-refs under Visual Studio - please provide an example where cross-refs
resolving is a really tough task - this sample shouldn't be the case where
one decides to resolve cross-refs in a legacy "spaghetti" set of projects
IOW we assume we're talking about experienced developers who prevent having
"cross-refs" spaghetti by doing code
clean-up/refactoring/de-cross-referencing once in a while within a project's
sources life-time...

I have to point out that it is exceptionally easy to create circular
references when the projects are set up like this.  That's why in our apps
we keep all the forms in a project, all the reports in a project, etc.  Of
course, if we were using libraries rather than projects under the solution,
it would be different.  But this way, it can get messy fast.

Hi John --

In fact this is easy (please correct me if I'm wrong):

- just reference your child projects from your main project and if you have
(sub-)child projects then reference them from child projects; you can also
reference child-child-(nephew) projects from parent projects etc... - just
avoid having circular references...

All that is very similar to MS Access/VBA references but unlike in MS
Access/VBA in .NET solutions this referencing always work without any
glitches whatever size your solutions are - tens of projects, thousands of
customer classes - no problems, no GPFs of Visual Studio (well, for ASP.NET
and WPF solutions you can have GPFs but even in that case you'll have all
your sources preserved).... 

<<<
I also don't understand why some objects in a referenced project class can
be seen but others cannot.  
>>>
That should be your problem/issue: in VS2008 (Prof) you can always try to
hint VS asking to "resolve" undefined class name, enum, global var - right
click -> Resolve... - if it can't do that - you can always do that manually
- but it may be needed to have some custom classes "shuffled" between your
projects...

the whole "break into

 > Why not have several (FE) applications if they are so independent? - all developed within one VS 
solution but as separate (WinForms) projects sharing the same (set of) class library(-ies)?

It seems like that may be what I am doing?  I have a single solution.  Inside of that solution's 
physical directory I have multiple projects, each in its own directory.  As I expand the solution I 
do an add / new project from the main solution / project.  Doing that takes care of creating a 
directory structure for each new project, but causes it to be created under the main solution directory.

Each project does not depend in any way on any other project, though I do have some shared 
libraries.  Each child project is referenced by the main project, but the child projects do not 
reference other child projects.

Now whether each of these independent projects ends up as individual applications I don't have a 
clue.  I was just tying them together with a single form / menu so that I have one central 
application to go to to find everything.

Thanks, but I am quite sure I would just get lost.  You have way too much faith in my C# abilities 
at this point in time.  ;)

I have found at least two dlls that can be referenced and used from C#.  Each claims to be "managed

something that is easy to use and documented so I can figure out how to use it.  I have a lot of

Hi Michael

Neither have I, but I googled a little on the "zubject" and several links tell that this GZip compression is not compatible with WinZip and the like because of missing file info, in other words it should be fine for compressing and decompressing a stream (which of course can be written/read to/from a file) but that's all.

A bit strange that this widely used function is missing from the framework.

 > Have a look for DotNetNuke sources

Thanks, but I am quite sure I would just get lost.  You have way too
much faith in my C# abilities 
at this point in time.  ;)

I have found at least two dlls that can be referenced and used from C#.
Each claims to be "managed 
code" and make the source available, though what that is worth to me is
not clear.  I just want 
something that is easy to use and documented so I can figure out how to
use it.  I have a lot of 
uses for zip files, from zipping up archives of files for near line
storage to making true zip files 
for shipping to clients.

Subject: [dba-VB] Do you wanna learn c#?
Message-ID: <4B25B4CE.9010105@colbyconsulting.com>

Have I got the book for you.

http://www.amazon.com/Microsoft%C2%AE-XNA%C2%AE-Game-Studio-3-0/dp/0735626588/ref=sr_1_2?ie=UTF8&s=books&qid=1260761698&sr=1-2

I bought this book because I found the XNA studio and wanted to learn all about how it works.  But 
this book is about teaching programming, and from that C#.  For anyone who knows vba or VB.net it 
will start off easy, but for anyone who doesn't program at all it also starts off easy.  This might 
be the best book for learning to program (in general) I have run into.  Plus it is fun.

You need Visual Studio (express is fine) and you need the XNA studio (it is also free).  An XBox 360 
game controller will be required pretty quickly.  I bought the cheapest controller for $15 from 
Wally world.

Then start reading (and writing).  I am on chapter 5 now (in about three days) and working on 
through it.

I swear you will learn C#, have fun while you are at it, AND learn how the XNA game studio framework 
works which is also an awesome tool.

Really folks, this is the real deal, if you have always said "I should..." do this one.  Or get your 
teenager involved in it.

I bought the book new from Amazon for about $20, plus the controller.  Everything else is free. 
That is a great deal folks!

I am working on creating a single field index on every field of a table.  I promptly ran into so 
many problems making it generic that I punted and went back to hard coding the database / table 
name.  I did find this:

select Name as FldName from psm11203.sys.columns
	WHERE object_id = OBJECT_ID('PSM11203.dbo.tblOrderData')

Which does give me a table of field names.  Using this in a cursor I am then able to create an index 
on each field, so I am off and running.

This is really a one off process that I need to run on my tblHSID - the table from hell from the 
database from hell.

I have to tell you I am a bit hesitant to pull the trigger in this for the table from hell.  It is 
going to take many minutes to build each index and there are well over 500 fields to index.  I could 
end up locking up my database for the next month.  ;)

I did create a copy, created a clustered index and will be creating all of these indexes on that 
copy, but even then it pretty much uses all of the resources of the server.

Subject: [dba-VB] A Parameters syntax question
Message-ID: <c09.73631826.3858baa7@aol.com>

 
Hi All
 
I'm connecting a vb2005 DataGridView to an Access db via vb code to  return 
a subset of records from a table. Using the GUID dataType it works fine  
but when I change the datatype I get all the records.
 
I'm using the Imports system.Data.OleDb class. From there I have OleDb  
connection, Command, DataAdapter and a Dataset.
 
EG.
With Command
    .CommandText = "QueryName"
    .CommandType = CommandType.StoredProcedure
    .Connection = OleDbConnection
    .Parameters.Add("@REFNOC", OleDbType.Guid,16).Value  = New Guid(REFNOC)
end With
 
Every thing works as it should. That is until I change the the datatype in  
the Parameter line and try to use a string or Integer.
 
I can't get the syntax right for the .Parameters line. If for example I  
change the .Parameter to say
 .Parameters.Add("@REFNOC", OleDbType.Single).Value = REFNOC I get all  
records
 
Can anyone cast a little light here?

Message-ID: <4B295D18.7070000@colbyconsulting.com>

Well my Vista Windows Media Center (WMC) finally bit the dust.  Something happened (a SP install I 
suspect) and the codec got trashed (I think) and suddenly WMC no workee - no tv of any kind, already 
recorded or off of the tv card.

As a college student I qualify to buy a copy of Windows 7 for $29 which sounded too good to pass up. 
  And that version supposedly had a much improved MCE.  So I did.  Bought it, and installed it ON A 
30 gb FLASH DRIVE last night.  Finished about 3:30 am.  She workee again.  In the meantime I also 
went from a low power dual core to a medium powered quad core, but twice the ghz rating.  Needless 
to say the Home theater PC flies.  Now if it will just work for a long time with no maintenance.

Hey John,

Did you install the SQL Client Tools?  I was just reading something about
this today.  I think the SMO stuff is installed with the client tools.  I am
not positive though.  If this does not solve your issue, I'll see if I can
find that reference tomorrow.

To all,

I use a lot of recordsets, and to detect they actually contain something I
have always used the following:

If myrecordset.bof=false and myrecordset.eof=false then

Else
    msgbox "empty"

Is there actually a prefered way, or is one quicker than the other, or is
there an even better way to do this ?

Thanks in advance for any comments, and a very merry christmas & happy new

Hi Paul
Well I'll wait to be corrected but I reckon they're simply two syntactically
different ways of saying the same thing. They'd surely compile into the same
code. So it just comes down to preference of style and readability, i.e.
totally subjective

To all,

I use a lot of recordsets, and to detect they actually contain something I
have always used the following:

If myrecordset.bof=false and myrecordset.eof=false then
    do my stuff here
Else
    msgbox "empty"
End If

However my project manager prefers:
 If not myrecordset.bof and not myrecordset.eof then
    do my stuff here
Else
    msgbox "empty"
End If

Is there actually a prefered way, or is one quicker than the other, or is

Or you could do this (which I prefer)

If not rst.eof then
Do my stuff
Else
Msgbox "who nicked my records"
Endif

Ps. Who is the programmer?  You, or the Project Manager?

Paul,

Perhaps better would be:

if MyRecordset.BOF and MyRecordset.EOF then
	msgbox "Empty"
else
	do stuff here
endif

It is easier to read the true than the nots, especially when there is more than one.  Either one 
works.  If this is in a tight loop and speed matters, then the NOT might cause a very slight 
slowdown as it is two extra boolean operators.  OTOH the compiler might just pick it up and rewrite 
it to my syntax anyway.

John,
I don't think that will work...something from Getz etc sticks in my
mind...might be old age though.

Hello John,

I have struggled with this value, and mixed it up with the connectionTimeout
also.  As a result, when I think there will be a delay, I also set it to
zero, and then I sleep easy.  I did that two years ago with
out troublesome app, and now it works and works and works.  Whats the
downside of infinite timeout.  If it takes three weeks, you will find out
anyway, but why kill it after ten mins when it would have finished
successfully in 19.45 minutes.

I hear you!

BTW how do you kill an executing stored procedure?

Hello John,

Not sure, but stopping the server is one way.  My main problems were sprocs
stopping when I did not want them to stop, for me, if it is still running
after 24 hours, it is probably never going to stop.  For you, you might
increase that to 48 hours, but in general, they either finish promptly, or
else will never finish, either way, timing out after 10, 20, 50, or even 600
minutes is almost never a good option, if there is a possibility that it
will finish in 601 minutes.

There is probably a way to stop a process, Francisco or some of the other
experts may know how, but I would either stop the db server / service, or
else in worst case, do a quick reboot.  For the rest of the year, I would
never worry about it, happy in the knowledge they the server must work till
the death :)

Thanks

Mark

Mark,

 >but I would either stop the db server / service, or else in worst case, do a quick reboot.

I have done both.  I have corrupted the database doing the reboot.  Stopping the service seems to 
work, however I have also seen the database pick up where it left off when the service restarted.

I am sure there is some way to "officially" stop a running process, I just don't know how.

Subject: [dba-VB] C# - Records Affected
Message-ID: <4B153F3A.8010102@colbyconsulting.com>

I am trying to get a count of records appended, updated etc in my SPs and returning that to my C# 
supervisor.  I am finding references to @@Rowcount however this is returning 1 instead of the actual 
number.

Is this @@RowCount the real deal?

The SP definition:

ALTER PROCEDURE [dbo].[sp_AZOut_AZExportToOrderedChunk]
	-- Add the parameters for the stored procedure here
	@DBName varchar(50),
	@ErrorDesc varchar(4000) output,
	@ErrorNo int output,
	@RecsAffected int output

AS
BEGIN


Setting the returned value

	EXEC (@SQL)
	select @RecsAffected = @@RowCount

My c# code:

intRecsAffected = sCmd.Parameters["@RecsAffected"].Value

The code triggers the try block if there is no such parameter (I just ignore it) or returns 1 if the 
parameter exists.

This is a functioning tested SP which typically appends millions of records, though the exact number 
depends on the database.

Is there something I need to know here?

<quote>
Do a select * from sysprocesses and identify the spid in question. Then do a "KILL 
<spidno>"

This will mark the spid as "dead". Note that it may take a while for the process to end as it 
has to rollback all the updates that it has been doing. Also kill only marks the process as 
dead - the process itself needs to check for this, and if it is stuck in a loop as the result of a 
bug or whateverthen it won't terminate. Also certain processes like dump and dbcc 
commands have significant code paths where the kill command is not checked for and so 
these can take some time to terminate.

Also, if the process is in an extended-stored procedure, or is waiting on network 
traffic/remote stored-procedure it will not check whether it has been terminated until these 
actions have been completed.

See Q171224 for more info - including details on the waittype that can tell you what a 
process is waiting on.

If the process won't die for one of the above reasons then your only choice is to stop the 
sqlservr.exe process itself and re-start.

</quote>

See also http://msdn.microsoft.com/en-us/library/aa933230%28SQL.80%29.aspx
for info on KILL x WITH STATUSONLY for tracking the rollback once you kill a process.

Sorry for the ring, I found the problem.

The SP that I took this code from actually worked but the code I was testing did not and came before 
this code.  The problem was simply that in the SP I did not place the line that captured @@RowCount 
immediately after the EXEC (@SQL) statement.

All of the examples clearly warned me that this was a requirement but you understand "senior moments".

Anyway, this is now working.

Piece by piece this thing is coming together.

As previously mentioned, over the last couple of years I have built up a set of stored procedures 
which perform TSQL.  I then run sets of these stored procedures to perform processes.  The TSQL is 
always dynamic.

As an example a stored procedure might build a table, with boilerplate field names and data types, 
but a passed in database and table name.  Inside of the stored procedure I build up the correct SQL 
to create the table in the database specified, with the name specified.  Another stored procedure 
might create in index, with boilerplate field names, but a passed in database and table name.  Again 
the stored procedure builds up the TSQL statement to create the index in the correct db and table.

I already have these stored procedures debugged and working and have been using them in sets to 
perform "big picture processes" for quite some time, but the whole "execute a stored procedure" 
using a command object, parameter objects in a parameter array, interpreting the parameters etc just 
seems so... 1950s.  I feel like I am flipping switches on the front panel of a computer in a 50s 
sci-fi movie as a tape reel spins madly in the background.

Now that I am moving to C# I am wondering if this is required any more.  Can C# execute TSQL 
directly somehow?  Can I assemble this boiler plate plus database / table kind of thing into a TSQL 
statement directly in C# and then somehow tell SQL Server to execute that TSQL?  I understand the 
"SQL optimization" thing but it seems like (not sure here) that because the TSQL is dynamically 
constructed in the stored procedure, the whole "optimization" thing goes right out the window.  If I 
can execute TSQL directly from C#, what can I get back?  Rows affected?  Error codes?  And how?

As it stands I am happily flipping switches, tape reels whirring, exporting data for address 
validation.  This is good, I am happy, but ...

Hi John --

I must say I have never done that "dynamic" t-SQL via C# - I guess it should
be doable: using SMO or even SqlCommand's .ExecuteNonQuery(?) it should be
possible to create SPs and UDFs, and then execute them as usual...

BTW, UDFs, which return tables are very often a good substitute for all
kinds of temp tables and dynamic SQL...

I wonder what for all that "dynamism" there? 
Do you have constantly changing database structure?
Do you have constantly changing customer requests, which do not allow you to
create a set of stable parameterized SPs and UDFs, and for small(?) changing
part of queries use LINQ for SQL or ADO.NET EF?

Thank you.

Hi John

As I see it, that would be LINQ and ADO.NET EF (Entity Framework). Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you. Critics tell that this SQL could be long-winded (= not optimized) but what do I care? If it flips 17 or 87 switches does nothing to me as long as the result is fast and precise.

ADO.NET EF is an amazing piece of work. It is not mature but if MS continues to evolve it with the same speed as Silverlight I'm sure it will catch up.

Message-ID: <c7fd28d00912020223q1c3e0388sec97ee600fd01dd2@mail.gmail.com>

Hello All,

I am running VS 2008 on a powerful machine with loads of resources.  My
project is a DNN project sitting in the wwwroot folder which allows me to
change a few lines of code and then immediately see the results in the web
app.

However, when I manipulate the Data Context Objects in the AppCode Folder,
the response times are dreadfully, slow.  It takes three to four minutes to
open, edit, save and close one of these objects.

I have tried it on a second machine and the results are similar.

I can edit the Dbml files outside of the solution, but I am not sure whether
that is safe to do so, when I edit them outside the solution (copying and
pasting to another folder and then opening the dbml file from there), they
open instantly.  When I say "safe to do so", does the project file or the
sln file need to be updated with the changes that have been made.  I do get
some warning message about "cannot find web.config, so using the file from
the dbml file instead" which I accepted.

I recall Shamil mentioned that manually editing these within the individual
files is not a good idea, so i guess that he may have been suffering the
same problems as I am, IE so sloooow to open and close.

TIA for an help, if I have not expressed the problem clearly enough, let me
know,

Mark

Hello Mark --

First of all try to switch to FireFox - forget IE while debugging large
ASP.NET apps from within VS....

I  can only note that debugging large ASP.NET applications is a real PITA -
this is why I'm always trying to get out as much as possible BL and DAL code
into separate projects and develop, debug/test them without UI (ASP.NET or
WinForms or WCF)...

And DNN is a "huge ASP.NET" app with a lot of classlibs, which are so
tightly coupled together that there is no way to debug part of them outside
of running DNN instance - with all the consequences - bad luck...

I suppose you can edit DNN's Data Context Objects source code from AppCode
outside of VS (e.g. within notepad) - when the edits are saved then DNN will
restart, that could take a while, quite a while....

A temp solution could be to keep *all* the source code of DNN module's
control within that control's code behind .aspx.cs (.aspx.vb) during
development - when you edit your code there then ASP.NET app will not
restart it will just recompile .aspx and .aspx.cs - so it should work
considerably quicker...

All in all I think DNN custom modules development is a RPITA - one can never
know how much it will finally take for a given project if they will not try
to find a way to debug/ test as much as possible code outside of running
DNN: something like develop a separate ASP.NET application, make it working
and then port it to DNN environmnet...

Be prepared for "crazy debug sessions" (if I'm  not missing something and
there are some "miracle" tools, which simplify DNN custom development
debugging)...

Philosophic note: DNN seems to be a good example that there "are no miracles
in this world" - DNN is a great prototyping tool and CMS, when one has ready
to use DNN modules and skins, and DNN is becoming RPITA when one have to
develop a(n) (advanced) custom module. Rhetoric Question: Why in this world
there couldn't be a "silver-bullet" tool able to support both standard and
custom development with the same ease as DNN does support CMS development?

I guess "Ruby on Rails" could be "what doctor ordered"?...

Or ASP.NET MVC2 Framework?

DNN did grow from a "junky" MS ASP.NET sample code base, and even advanced
developers as DNN Core Development Team members are can't still "convert"
that original "junk" to pearls...

Hopefully they will do that in DNN v.7? - they "just" need to clean-up DNN
huge code base and to implement what is called "Inversion of Control"
(http://martinfowler.com/articles/injection.html) to "untight" DNN Core
classlibs as much as possible...

Please correct me if I'm wrong - in fact I'd be really happy to be wrong
here as I have had to suspend one of the DNN projects, which didn't go
smoothly because of PITA DNN custom modules development experience...

Sorry, Mark, I have no a definitive answer for you here - just some "soap"
and "bubbles" and PITA of my own DNN custom modules development experience,
which I need to find a way to workaround, or quit the idea of DNN custom
development completely as it's too expensive to be true. Still hope I missed
some approaches to simplify this development - I mean ready to use
approaches and tools without long learning curve...

Thank you.

doing any debugging, in the traditional sense, I code a few lines, click
save and then view the results in Chrome, when I am not happy, I flick back
to VS, change it and continue again.  So, it is true to say, I am not really
debugging, just viewing.  However, I stopped using IE a few years ago, and
since I switched to Chrome, it is the first thing I install on new machines.
 With the exception of the MSDN site, it works perfect for me.


*Slow Data Contexts*
So can I assume that this slowness is simply to be accepted, it is either a)
the way VS2008 usually performs, or b) the way VS2008 performs when data
contexts are involved in a large project such as DNN.  I did not notice any
difference when I copied the code from the wwwroot folder, so I hope that is
not part of the problem.

*DNN Development*
Probably I am not doing real DNN custom programming, but I am currently
building web user controls, and simply saving them, and then creating a
module for DNN and including the web user control on that module.  I know
this is not real DNN programming, but have created about 20 module so far
like this.  DNN gives me, as a script kiddie type programmer, they ability
to do a simple web app, but it manages the users and authentication,
something that I could never program.

IOW, with the exception of a few DNN hooks, I am doing simple programming,
but throwing the results into DNN.


*Free Lunch*
I have to say I agree with you, there are limitations everywhere.  My
appoach is always to keep it as simple as possible until I absolutely know
that I need to make it more complex.

Shamil,

As I have discussed in the past, the business is doing the exact same process to many different 
tables.  Because of the size of these tables and the processing involved I find it useful to store 
each table in it's own database.  These are just lists of names, each list comes from a different 
source and is called something by the client, something that makes sense to him.  These lists (a 
table) will always be millions of names / addresses, and often are 50 million or more.  When you 
have 50 million names, the database, with just this one single table will be 10 or 20 gigabytes. 
Once you start processing it can mushroom to 50 gigabytes.  Thus storing a dozen of these tables in 
a single database just doesn't make sense (to me).

Thus I have a dozen different databases.

I have to apply all of these stored procedures to each one of these databases once a month.  Thus 
write the stored procedure such that I can pass in a database name and a table name.  Voila, the SP 
works for all of my databases.  But that means dynamic SQL.  I really don't have an issue with 
dynamic SQL, although I have witnessed first hand the time required for SQL Server to do the 
"compile" - creating the execution plan.  If I run the SP a second time with the same db and table 
name the time to execute drops sharply.

BTW, these lists become the source for "orders" of names.  Each of these orders also are stored in 
its own database, and I have to execute these same (or similar) SPs against each of these orders. 
Over the last 4 years I have perhaps a hundred of these order databases.

This is what I do for this client, create these databases, and apply processes against these 
databases.  The processes are exactly the same across all of the databases, thus having a stored 
procedure that performs some part of that process but can be applied to any of these databases makes 
sense (to me).

I have spent the last five years performing these processes entirely manually, then one by one 
creating a stored procedure to automate one of the steps, then the next step, and the next.  By now 
I have an entire master library with (let me go check) 42 different stored procedures that, taken 
together, automate my work for the client.

THAT is the point of the C# side of things.  Automating the automation so to speak.  Taking these 42 
stored procedures and stringing sets of them together, 7 which perform the output of data to an 
external program for processing, 6 more that get the processed data back in, a half dozen more that 
perform some other processing, another set that do order processing, etc.

This is not a bank, or a company or a call center or a manufacturer, or any of the other "typical" 
SQL Server databases.  It is name / address list processing and creating orders from these lists. 
Really pretty simple but extremely painstaking.  And like anything else we do, I can't be making 
mistakes, it must be done in a specific manner, a specific sequence, EVERY time.

Message-ID: <38c884770912020805s570c99e1ia753bf4f81b4d0f7@mail.gmail.com>

To all,

We have been a given what looks to me like a fairly complex XML file, we
have also been given a xsd schema file.  I tried using the SQLXMLBulkLoad
object in VB6 and was getting the error

Schema: relationship expected on 'Company'.

The company that gave us both the files insist that the xsd is correct
(according to my project manager).  I downloaded and installed Stylus Studio
2010, with which I loaded the XML, and then generated my own xsd schame
file.  Tried again and this time get the same error as above, but instead of
'Company' the error was 'Groups'

The VB6 code I am using is as follows:

Dim objBL

Set objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad")
objBL.ConnectionString = "Provider=SQLOLEDB.1;Password=hermes;Persist
Security Info=True;User ID=sa;Initial Catalog=XLTestCD;Data Source=AL-SQL1"


objBL.KeepIdentity = True

objBL.errorlogfile = "C:\XML_StylusStudio\Error.log"

objBL.checkconstraints = True
objBL.xmlfragment = True
objBL.schemagen = True
objBL.sgdroptables = True

objBL.Execute "C:\XML_StylusStudio\newschema.xsd",
"C:\XML_StylusStudio\CDFull_Original.xml"
Set objBl=Nothing

The object of the exercise being that we generate related tables in SQL
Server 2005 of the XML data.

Would be grateful if anyone could help with this (would be happy to send
example XML file and the schema offline), as I haven't got much hair left to
pull out.

Thanks in advance for any help on this.

Hi John --

Thank you for your reply.

Do you use your different databases for data input, or you also have to
update those different databases' tables?

Hi John

As I see it, that would be LINQ and ADO.NET EF (Entity Framework). Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you. Critics tell that this SQL could be long-winded (= not optimized) but what do I care? If it flips 17 or 87 switches does nothing to me as long as the result is fast and precise.

ADO.NET EF is an amazing piece of work. It is not mature but if MS continues to evolve it with the same speed as Silverlight I'm sure it will catch up.

As previously mentioned, over the last couple of years I have built up a set of stored procedures 
which perform TSQL.  I then run sets of these stored procedures to perform processes.  The TSQL is 
always dynamic.

As an example a stored procedure might build a table, with boilerplate field names and data types, 
but a passed in database and table name.  Inside of the stored procedure I build up the correct SQL 
to create the table in the database specified, with the name specified.  Another stored procedure 
might create in index, with boilerplate field names, but a passed in database and table name.  Again 
the stored procedure builds up the TSQL statement to create the index in the correct db and table.

I already have these stored procedures debugged and working and have been using them in sets to 
perform "big picture processes" for quite some time, but the whole "execute a stored procedure" 
using a command object, parameter objects in a parameter array, interpreting the parameters etc just 
seems so... 1950s.  I feel like I am flipping switches on the front panel of a computer in a 50s 
sci-fi movie as a tape reel spins madly in the background.

Now that I am moving to C# I am wondering if this is required any more.  Can C# execute TSQL 
directly somehow?  Can I assemble this boiler plate plus database / table kind of thing into a TSQL 
statement directly in C# and then somehow tell SQL Server to execute that TSQL?  I understand the 
"SQL optimization" thing but it seems like (not sure here) that because the TSQL is dynamically 
constructed in the stored procedure, the whole "optimization" thing goes right out the window.  If I 
can execute TSQL directly from C#, what can I get back?  Rows affected?  Error codes?  And how?

As it stands I am happily flipping switches, tape reels whirring, exporting data for address 
validation.  This is good, I am happy, but ...

Shamil,

I receive lists of names in CSV or fixed width files.  I import those into SQL Server, creating a 
PKID in the process.  I then have to export the PKID plus the name / address monthly for address 
validation.  Once validated, I have to import the data back in.  This is the monthly process. 
Approximately 1% of all the people on any given list move each month.  So I have to go back in to 
the original list and update 1% of the addresses, or simply swap out the new list (table) for the 
old.  There is never any manual processing of individual names inside of these lists, IOW people 
never look at them, modify them, add new ones, delete address or anything like that.  The list is 
"stable" in that regard.

These lists become the source for orders of names.  Orders are a whole 'nother process, but also use 
SPs to do their thing.

Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you.

John --

Have you tried to use MS SQL database filegroups and partitioned tables &
views?

http://msdn.microsoft.com/en-us/library/ms345146(SQL.90).aspx

With them I suppose only initial import/insert of data have to be
parameterized with table name, and the rest can be done without any dynamic
T-SQL. Please correct me if I'm wrong.

Please note I'm not trying to "force" you to change your current working
solution - just wondering is there a legal way to solve your task without
dynamic T-SQL...

Shamil,

I have not.

All of that is rather esoteric stuff for a non DBA.  My job is processing data, and that is only a 
small part of my job, i.e. this is only one of many clients, and the only one that needs this kind 
of SQL Server stuff.

As I have said many times, if my job was to go into a company every day and play DBA then I would 
learn many more things SQL Server related.  As things stand I learn just enough to make things work, 
and a LITTLE extra in search of efficiency.  It is certainly not that I don't want to, I just don't 
have the time.

In the end I find the method I use comfortable from many angles.  I have to do some things that 
require creating views, other "processing" tables and so forth.  It really just works (for me) to do 
things this way, have separate databases to hold all of the "junk" associated with each list.  Kind 
of the old "encapsulation" thing.

Your suggestion would of course end up with all tables inside of a single "database", and as such 
the need for the Database parameter would go away but I still have to do the same thing to many 
different tables.

Again, could this be done by one of the experts on the SQL Server list.  Probably!  Will I ever get 
there?  Uhhhh doubtful.

Hi John --

OK. Don't break it with implementation of other approaches if it works...

Just for the future projects - I suppose (I might be missing something as I
do not have that experience but I plan to try, maybe within our
Northwind.NET project) this partitioning stuff is just practical for the
tasks as you do (similar stuff was available for non-relational DBMSs in the
end of 70-es/beginning of 80ies, and for Oracle it's available for years now
AFAIHH), and this stuff doesn't take that much time to learn (one day?)  and
use (a few short reusable T-SQL scripts?) that it would  take to program and
to test and to support dynamic T-SQ: for many SPs and UDFs...

Thank you.

If that stats will help you to quote and to plan your projects, please write
a short note to be posted there (myself or Gustav can post it)

- 25 objects or so, I have to sit like a donkey and click for almost two
hours.

It still takes four minutes to open and edit one.

A PITA for sure.

If I open the class as a standalone file, I can operate with
instant performance, but it does not play well with the project/ solution.

I have to say, I wish I knew more about these data classes and how they
really should be used in real world applications.

Thanks

Mark

Hello Mark --

OK, I suppose you can create custom DLL(s) working with LINQ to SQL in a
solution outside of your custom DNN solution, and then just use your custom
DLL within custom DNN solution - your LINQ to SQL objects from DLL should be
public and this DLL should also have its own config file...

I have done something like that but with POCO-objects
(http://en.wikipedia.org/wiki/Plain_Old_CLR_Object), which I used as
ObjectDataSources for web forms within DNN custom solutions' custom
modules...

Thank you.

Hello Shamil,

In VS2008, when I create a folder in app_Code, and then create a new Linq to
SQL Class is it assigned the extention of dbml, default name is
DataClasses.dbml

It is these classes that are sooo slooow to do anything with.  I timed the
time it takes to just click create, drop a table onto the design surface,
and then click save.  It is taking 4 minutes to do that, so when I needed 20
- 25 objects or so, I have to sit like a donkey and click for almost two

It still takes four minutes to open and edit one.

A PITA for sure.

Hello Shamil,

I guess this is an option for me, but to be honest, it will probably more
easier  for me to take the delay of waiting that attempt to manage the
additional layer of complexity.  As with all things in life, I suppose if I
take the time to review this, it will save me time, but I am afraid to spend
a day on it only to save myself a few minutes a few times a day.

Thanks any way for the suggestion,

Mark

Create an xml file called UserSettings (or whatever) and store each value in a node in that.  Then all you have to do is read them back when you need them.  We use several of these, one called OLEDBSettings.xml that looks like this: 

  <?xml version="1.0" standalone="yes" ?> 
- <NewDataSet>
- <connection>
  <dbtype>0</dbtype> 
  <provider>Microsoft.Jet.OLEDB.4.0</provider> 
  <datasource>C:\Documents and Settings\All Users\Application Data\Infostat\RIMDrill\5\RIMDrillData.mdb</datasource> 
  <userid>RIMUser</userid> 
  <password /> 
  <initialcatalog /> 
  <trusted>false</trusted> 
  </connection>
- <connection>
  <dbtype>1</dbtype> 
  <provider>sqloledb</provider> 
  <datasource>infoserver</datasource> 
  <userid /> 
  <password /> 
  <initialcatalog>RIMDrillDataSQL</initialcatalog> 
  <trusted>true</trusted> 
  </connection>
  </NewDataSet>

We actually have a file like this for each application and it lives in the application folder.  This is just to give you an idea, not a how to.   We have a class that wraps this in our apps and uses this kind of routine to read it.  I leave it up to you to translate to C#.

    Shared ds As DataSet
    Shared _connectionString As String

    Shared _xmlPath As String = "OLEDBSettings.xml"         'default to xml file in apppath

   Private Shared Sub ReadSettingsFile()
        If IO.File.Exists(_xmlPath) Then
            Call CreateSchema()
            ds.ReadXml(_xmlPath)
            Call DecryptPassword()
            _connectionString = GetConnectionString()
        Else
            If ds.Tables(0).Rows.Count = 0 Then
                'placeholder for jet settings
                Dim row As DataRow = ds.Tables(0).NewRow
                row("dbtype") = 0
                row("provider") = "Microsoft.Jet.OLEDB.4.0"
                ds.Tables(0).Rows.Add(row)

                'placeholder for sql settings
                row = ds.Tables(0).NewRow
                row("dbtype") = 1
                row("provider") = "sqloledb"
                ds.Tables(0).Rows.Add(row)

Hi Charlotte,

I see this as useful, but,
If you need a complex setting structure why not just create a
'MySettings' class and serialise or deserialise it as needed?
I think John has already worked with the Serializable attribute.
Am I missing something?

Cheers

Hi John

Yes and no. I used an old version for some time but the current version is more powerful.

Please note that it comes with all the examples from his book, and even without the book this is a great why to get your hands on LINQ as the code is "live" - no need to copy and paste, it is right there for you try out at once.

Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you.

Subject: [dba-VB] LINQ example (was: C# - Direct data manipulation)
Message-ID: <sb18eda8.001@cactus.dk>

Hi John et all

Further to the notes below on Joseph Albahari's LINQPad, it contains a link to download all the example code from "LINQ in Action".
Also, it has a link to this amazing demo of the power of LINQ:

http://blogs.msdn.com/lukeh/archive/2007/03/19/using-linq-to-solve-puzzles.aspx 

It's a true eye-opener and a good example showing that the scope of LINQ is much wider than "normal" database querying.

The code is included in LINQPad when downloaded, ready for you to play with at:

  Tab Samples, 
  C# 3.0 in a Nutshell, Chapter 9 - LINQ Operators, Joining, Extra - Weights Puzzle. 

It's Friday and soon weekend!

Hi John

Yes and no. I used an old version for some time but the current version is more powerful.

Please note that it comes with all the examples from his book, and even without the book this is a great why to get your hands on LINQ as the code is "live" - no need to copy and paste, it is right there for you try out at once.

Subject: [dba-VB] Read XML File Using xsd Schema File
Message-ID: <38c884770912040419xdc61c66y2c315b820cd6fb09@mail.gmail.com>

To all,

We have been a given what looks to me like a fairly complex XML file, we
have also been given a xsd schema file.  I tried using the SQLXMLBulkLoad
object in VB6 and was getting the error

Schema: relationship expected on 'Company'.

The company that gave us both the files insist that the xsd is correct
(according to my project manager).  I downloaded and installed Stylus Studio
2010, with which I loaded the XML, and then generated my own xsd schame
file.  Tried again and this time get the same error as above, but instead of
'Company' the error was 'Groups'

The VB6 code I am using is as follows:

Dim objBL

Set objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad")
objBL.ConnectionString = "Provider=SQLOLEDB.1;Password=hermes;Persist
Security Info=True;User ID=sa;Initial Catalog=XLTestCD;Data Source=AL-SQL1"


objBL.KeepIdentity = True

objBL.errorlogfile = "C:\XML_StylusStudio\Error.log"

objBL.checkconstraints = True
objBL.xmlfragment = True
objBL.schemagen = True
objBL.sgdroptables = True

objBL.Execute "C:\XML_StylusStudio\newschema.xsd",
"C:\XML_StylusStudio\CDFull_Original.xml"
Set objBl=Nothing

The object of the exercise being that we generate related tables in SQL
Server 2005 of the XML data.

Would be grateful if anyone could help with this (would be happy to send
example XML file and the schema offline), as I haven't got much hair left to
pull out.

Thanks in advance for any help on this.

Hi John

Oh, I misunderstood you.
Not until recently. Skipping the SQLCommand low-level stuff completely, I've used datatables with in-line SQL queries (to avoid designing T-SQL and special views - Shamil mobbed me for that choice!) and I have been busy learning just these - so one step further, no thanks. Also, I had a hard time grasping the lambda expressions and syntax and still feel I have a lot to learn. Yes, you can use LINQ without lambda, but that seems like LINQ without an arm and a leg. But - for anything else than some special cases like perhaps your cases - I'm confident LINQ is the route to follow.

I have to say that as a developer of a higher level language, I can see where avoiding TSQL would be 
  something we would try to do.  While I understand that SQL Server can be integrated into and used 
straight from the VS environment, most of us come at it from the built-in editor which frankly 
sucks.  And I mean REALLY BADLY sucks, no apologies to our admin friends.  I guess I have been doing 
SP development for a couple of years now and I still hate the built-in editor.  And yet... that is 
what I use.

IMHO this is an area where MS has fallen down on the job.  If this integration thing is so darned 
simple, then MS should push education, seminars, books, education, education to get us working in VS 
to run (program) SQL Server.  From a development perspective, and that is what SPs and UDF are after 
all, SQL Server should just be a tool used to manipulate data, NOT a dev environment.

Over the last month I have found two APIs that allow C# to do a ton of stuff directly in SQL Server. 
  WAY COOL stuff, but you would think it was porn the way you don't see it in the mainstream.  These 
APIs allow you to manipulate SQL server the same way you can manipulate any other object - create, 
delete, observe, modify, manipulate anything in SQL Server - straight from VS.  But where are the 
forums, the blogs, the developer excitement?  It appears to me that there is a very real "here is 
your database" aimed at the developers who use SQL Server, and the admins just do things the way 
they always have for the last 20 years.  And they buy tools from the RedGates of the world who 
undoubtedly do salivate over these new APIs.

Just my humble opinion.

Charlotte,

My question really is how do I get at the settings area of the project, and why would I not use that 
instead of this xml thing of yours?  At least in this specific case, I am writing code for myself, 
not distribution.

Hi John

One reason could be that many web developers know little about database design, thus they are being forced to leave that to a DBA. A chief developer once told at a tech meeting I attended, that they operated with the concept "scared of the database" meaning that the web developers should just be presented with ready-made views because SQL to these was like black magic.

I actually think that is a good thing, developers who just use data shouldn't need to be learning 
SQL Server to get their data.

That is really not the audience I am addressing however.  IMHO the built-in editor of SQL Server 
should either be removed entirely or at least brought into the current century.  It is notepad with 
pretty colors.  How many millions of man hours have been wasted trying to track down errors when the 
only error message presented was "error near (insert some unrelated thing here)".  Why bother even 
throwing up an error like that, and that is 99.9% of the errors I have EVER seen in two years 
working with SQL Server.

Notepad, with pretty colors.

For all of the rude comments us Access developers get about Access being "a toy", the code editor in 
Access is in a complete other galaxy from the code editor in SQL Server.  SQL Server editor looks 
like it was designed in 1986 and never upgraded.

Of course with the "real men don't use code editors" mentality of the DBA side of the fence I can 
see why MS doesn't bother spending time on this.

Someday I really am going to have to figure out how to use VS to run / debug my SPs and stuff.  To 
me VS just seems over-the-top complex for the level of stuff I am trying to do.  An Access type of 
code editor would be just the right level of convenience and capability - built right into SSMS.

Hi John

LINQPad does pure SQL too, though not with IntelliSense, and error messages seem to be those from SQL Server.

OK, then I don't understand the question.  What do you mean about the settings "area" of the project?

Charlotte,

My question really is how do I get at the settings area of the project, and why would I not use that instead of this xml thing of yours?  At least in this specific case, I am writing code for myself, not distribution.

Under the project is a properties object.  Double click that and an entire multi-tabbed dialog opens.

Click the settings tab.  There you will see a form where you can enter name, type, scope, value.

As far as I can tell this is a place where I (the developer) can create settings that my program 
will use and manipulate, settings (for example) to tell my program the name of the SQL Server 
instance to use in a connection string, the name of my control database where I store my stored 
procedures and UDFs.  Stuff like that.  Stuff that I am currently hard coding, but which really 
should be in a settings tab so that I don't have to remember where that constant is in code, I can 
just go to the settings tab to change.

My expectation is that there is an object somewhere in the .net namespace that allows you to do 
something like "Something.Somethingelse.Settings["MyServerName"]...." to access these things.

I expect to be able to create new ones, edit existing ones, delete them etc from a .Net object.  I 
am looking for that .Net syntax that allows me to do this from code.

Hi John,

You can access those properties using:

Properties.Settings.Default.{{PropertyName}}

Or

{{Root Namespace}}.Properties.Settings.Default.{{PropertyName}}

Hi John

Shamil is right, but that method is for reading only.
Please note that the Properties' collection object is read-only, thus it takes quite a few steps to add a property:

http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/c52b4fc6-66be-44ce-8a65-ab548f6f4f04

I have not used this as I haven't had any need to add properties on the fly. Reading and writing was fine for me, and new properties I added manually.

You may find it much easier and perhaps more convenient to just have a dataset which you read and write from/to an XML-file. I've posted code for this before.

Hi Gustav,

You can set 

Properties.Settings.Default.{{PropertyName}} = {{SomeValue}};

and save settings having "User" scope:

Properties.Settings.Default.Save();    

And they are saved not in {{ApplicationExecutableFileName}}.config, which
you deliver with you app's executable but anywhere else on your system -
probably somewhere in user's Application Settings - standard windows folder.
I have never had time to find out where settings are saved. Anybody?

Recap:

- settings are loaded from {{ApplicationExecutableFileName}}.config when you
deliver you application, and it runs first time;
- as soon as you save "User" scope settings they are saved in and loaded
from {{UnknownPlace}};
- if you move your application files into another folder on the same system
the settings are again loaded on first run from
{{ApplicationExecutableFileName}};
- ...

That looks confusing a bit but it's how it works...

You can click "Learn more about application settings..." on top right of
VS2008 application settings window available by Solution Explorer -> Project
name -> Right-Click -> Settings...

But if you wanted to have rather complicated structure of your application
settings file then better use your own custom XML files, which can be loaded
from/saved to files many ways without almost any coding...

Thank you.

Hi Gustav --

No, PropertyName can't be appended and saved if it doesn't exist as they are
compile-time (early) bound - but JC asked exactly about existing properties
defined in VS2008 project settings, and they can be changed and saved if
they have "User" scope.

Yes, I guess they are saved somewhere in AppData but I do not know where...

I have not used this as I haven't had any need to add properties on the fly.
Reading and writing was fine for me, and new properties I added manually.

You may find it much easier and perhaps more convenient to just have a
dataset which you read and write from/to an XML-file. I've posted code for
this before.

Under the project is a properties object.  Double click that and an entire
multi-tabbed dialog opens.

Click the settings tab.  There you will see a form where you can enter name,
type, scope, value.

As far as I can tell this is a place where I (the developer) can create
settings that my program 
will use and manipulate, settings (for example) to tell my program the name
of the SQL Server 
instance to use in a connection string, the name of my control database
where I store my stored 
procedures and UDFs.  Stuff like that.  Stuff that I am currently hard
coding, but which really 
should be in a settings tab so that I don't have to remember where that
constant is in code, I can 
just go to the settings tab to change.

My expectation is that there is an object somewhere in the .net namespace
that allows you to do 
something like "Something.Somethingelse.Settings["MyServerName"]...." to
access these things.

I expect to be able to create new ones, edit existing ones, delete them etc
from a .Net object.  I 
am looking for that .Net syntax that allows me to do this from code.

Hi Gustav --

No, PropertyName can't be appended and saved if it doesn't exist as they are
compile-time (early) bound - but JC asked exactly about existing properties
defined in VS2008 project settings, and they can be changed and saved if
they have "User" scope.

Yes, I guess they are saved somewhere in AppData but I do not know where...

Isn't the data saved under the user profile somewhere in AppData? I haven't

Hi Shamil

Well, much less hard-core than I had expected, indeed not a coding session but with a good perspective.
However, he came a long way describing and demonstrating many new features of VS2010, MVC and Silverlight. Also LINQ and ADO.NET EF seems to be mainstream. And, of course, much warmly promoting of Windows Azure which works very well together with VS, indeed with the new "local Azure" - a local simulator of Azure you can use during development so no live hosting is needed - much like the local web server that simulates IIS.

Very cool is the new GUI designer for Silverlight UI design. VS2010 is brushed up quite a lot with better support for multi-monitor use, improved IntelliSense and editing features in the code editor - everything is aimed at faster development with firm focus on you, the developer, very different from Access.
Further, the Team Foundation edition is now useful for single developers too, with unit testing, versioning etc. etc. However, I expect that to be available at a "corporate" charge only (beyond my budget), but let's see.

He promised to mail us links to the complete session and much more. I can post these here when they arrive.
If you or anyone else have questions to specific topics, Scott Guthrie may have touched, please ask.

Hi Shamil

He actually told that: March 22, 2010.

Further, I located this related link:

Also note the link to "Visual Studio 2010 and .NET Framework 4 Training Kit - October Preview":

Hi Gustav --

Thank you.
OK, March 22 - official release - so January 2010 MSDN might have it...

Hi Shamil

Well, much less hard-core than I had expected, indeed not a coding session
but with a good perspective.
However, he came a long way describing and demonstrating many new features
of VS2010, MVC and Silverlight. Also LINQ and ADO.NET EF seems to be
mainstream. And, of course, much warmly promoting of Windows Azure which
works very well together with VS, indeed with the new "local Azure" - a
local simulator of Azure you can use during development so no live hosting
is needed - much like the local web server that simulates IIS.

Very cool is the new GUI designer for Silverlight UI design. VS2010 is
brushed up quite a lot with better support for multi-monitor use, improved
IntelliSense and editing features in the code editor - everything is aimed
at faster development with firm focus on you, the developer, very different
from Access.
Further, the Team Foundation edition is now useful for single developers
too, with unit testing, versioning etc. etc. However, I expect that to be
available at a "corporate" charge only (beyond my budget), but let's see.

He promised to mail us links to the complete session and much more. I can
post these here when they arrive.
If you or anyone else have questions to specific topics, Scott Guthrie may
have touched, please ask.

OK, I am trying to reference

Properties.Settings.Default["ServerName"].ToString() and get the error

'System.Windows.Forms.PropertyStore' does not contain a definition for 'Settings' and no extension 
method 'Settings' accepting a first argument of type 'System.Windows.Forms.PropertyStore' could be

OK, it appears that each project has its own set of properties.  If I set the same property in the 
current project's property set then

Properties.Settings.Default["ServerName"].ToString()

works just fine.

But that is not the behavior I want.  I need a SOLUTION property set, which appears to not exist? 
Which perhaps would explain why those who have done this before roll their own?

Does anyone have code to do this so I don't have to roll my own (a.k.a. reinvent the wheel) too?

Hi John

The file containing the settings is app.config.

To hold "global" settings you could create a small project with just this file and reference it from any other project.

My understanding of Properties.Settings is that settings must be by User
in order to be saved and the xml file will reside in the Local 
Setting/Applications
directory under the user's My Documents folder.

In that case, all projects under a solution could read a single xml file.

We decided to use cryptographic services for the i/o of the xml by
using an internal static class that reads/writes to a string collection
using methods we created like bof, eof, movefirst, addnew, etc.

Hi John --

For solution you can select one of the projects to be used to handle
settings.
That project is usually a core(utility/generic/settings) class library.
Then if you wish you can additionally wrap 

Properties.Settings.Default...

for every/most of the settings into your custom global (Solution scope)
properties' wrappers. Such wrapping makes your referencing projects
independent on actual implementation of handling of application settings.
When that done and works OK you can go and "reinvent the wheel" if needed
without any changes in referencing projects...

Hi John

I think not. This old project uses the Shell dialogue and has a SetExpanded method. Maybe you can get some ideas:

Subject: [dba-VB] C# - Thoughts on my methods
Message-ID: <4B1FC705.9010902@colbyconsulting.com>

As a consultant in a home office I work in total isolation except for this email group.  So I need 
your input, to keep me sane and to keep me on the right path.  I would like your thoughts on what I 
am doing and what I am intending to do.

As you know, I have "the database from hell", for which I am developing an application to allow me 
to manipulate the various pieces from an application interface rather than directly from stored 
procedures and the SSMS or from Access, which is what I have done to this point.  With C# I am able 
to do more than I was able from Access, including getting back output parameters from stored 
procedures.  So... my process so far.

First off, I am developing the overall application as a set of child projects inside of the 
application.  The main application opens a form with a menu, and that menu takes me to forms in the 
child projects to perform pieces of the application.  For example I have a database backup project 
where I can backup and restore specific databases or groups of databases.  I have an Accuzip project 
where I can export CSV files to and import resulting CSV files from the external Accuzip program.  I 
have an Orders project where I can create and manipulate the orders I create for the client.

Each child project is physically located underneath the main application directory.  In order to 
reference (open) the forms in the child projects, I have to set a reference to that project and I 
have to set a using statement in the form.  I still do not understand what these two pieces do.  Why 
do I have to set a reference and a using?  I assume you cannot set a using statement unless the 
project references the library (or project)?

I also don't understand why some objects in a referenced project class can be seen but others 
cannot.  IOW I can use one class in a namespace as a type to dimension an object, but another class 
in the same namespace is not visible, cannot be so used.

I don't understand a whole ton of things of this nature and I have to say that the whole "break into 
projects" idea is turning out to be more work than it might be worth.

Any comments on this email will be much appreciated.

Subject: [dba-VB] threading
Message-ID: <4B1FF708.1040700@colbyconsulting.com>

As mentioned in previous emails, I am developing an application to manage all of the tasks for the 
DBFH.  This includes Backing up databases, creating orders, transferring data between an external 
app etc.  I am trying to determine how to thread this app such that if I start a process exporting 
data to Accuzip, I could have another process importing data from Accuzip, and also be working on an 
order.

As things currently stand, each of these tasks is a project and each project has its own forms and 
classes, and anything else necessary for that task.  I really do want to be able to do multiple 
things like this at the same time.  Exporting data to Accuzip can take overnight, and actually 
consists of an export and a matching import process.  It makes perfect sense (to me) to have threads 
doing this kind of thing, and allow me to go back to the main application and do something else.

But at what level would I use a thread?  Would I use a thread to open the form that performs the AZ 
process?  This would allow me to get that started and immediately go back to the main app and open 
another form (using a new thread?) to start processing an order.

Or would the form open and the button on the form start a thread that executes the process?  If a 
form starts a thread, that allows the user (me) to do other things in that form potentially changing 
to a new directory or selecting a different database.  Do you disable all controls on a form when a 
thread starts?  I never had to think about this in VBA and it is all rather confusing.

Why not have several (FE) applications if they are so independent? - all
developed within one VS solution but as separate (WinForms) projects sharing
the same (set of) class library(-ies)?

Hi John,

Have a look for DotNetNuke sources - they have free sources for
zipping/unzipping.
Those sources are used in core DNN functionality (modules setup) - IOW they
tested well, they are stable and thry work very well.

Hi John --

In fact this is easy (please correct me if I'm wrong):

- just reference your child projects from your main project and if you have
(sub-)child projects then reference them from child projects; you can also
reference child-child-(nephew) projects from parent projects etc... - just
avoid having circular references...

All that is very similar to MS Access/VBA references but unlike in MS
Access/VBA in .NET solutions this referencing always work without any
glitches whatever size your solutions are - tens of projects, thousands of
customer classes - no problems, no GPFs of Visual Studio (well, for ASP.NET
and WPF solutions you can have GPFs but even in that case you'll have all
your sources preserved).... 

<<<
I also don't understand why some objects in a referenced project class can
be seen but others 
cannot.  
>>>
That should be your problem/issue: in VS2008 (Prof) you can always try to
hint VS asking to "resolve" undefined class name, enum, global var - right
click -> Resolve... - if it can't do that - you can always do that manually
- but it may be needed to have some custom classes "shuffled" between your
projects...

<<<
the whole "break into 
projects" idea is turning out to be more work than it might be worth.
>>>
John, it will pay itself back very quickly - just be patient - I'd guess
(based on your software development experience) it will need max one week
(in total) of your time to spend mastering that multi-project solutions -
and when you're there - only outer space will be your limitation...

Just create a very simple sample solution with several projects and try to
play with it setting references, moving custom classes from one project to
the other, changing namespaces, and using directives... it's really easy -
imagine hierarchical catalog where child entries can be referenced/accessed
from parent ones, but where sibling entries aren't aware of each other...
(if only they do not inherit from the same parent entries...)

You can roll your own using J# from within VS.  Idid that originally and it only takes minor translation to put it into C# or VB.  That said, we currently use Xceed.

Subject: [dba-VB] Ajax application problem
Message-ID: <3262DDC894CA427DB254732FCE5E70AF@VOSTRO>

Hi all,


I have problems putting an ajax application on a production server.

The application consists of an aspx page that keeps the javascript code.
This code talks with C# page methods to access Web services and interact with the database.

For example the first thing the user has to do is fill in login and password fields and click on the btnLogin.

Then the code execute the following command:
PageMethods.GetUser(user, onGetUserSuccess, onGetUserError);

with user being an array containing username and password. The C# GetUser webmethod returns its response to the onGetUserSuccess callback function.

The application runs ok on my dev pc.

I installed it on the production server, copying the aspx file, web.config file and the binary files.

When I run it, I get an error message, something like error during the handling of your request.(freely translated from french!!)

This error is displayed into a textbox by the onGetUserError callback function. 
I put an error trapping withing the webmethod, but its error message is not returned, leading me to think that this webmethod is not "entered".
Therefore the javascript code is running ok, but the call to the webmethod is failing.

I guess I missed to copy something like a javascript file from the framework, or something else.

Do you have any kind of experience in this regard?

NB: I also checked that the asp framework is of version 2.0 on the server, it's ok.

TIA,

Philippe Pons

Hi Charlotte --

Yes, it's easy to create cross-refs, and it's (usually) easy to solve
cross-refs under Visual Studio - please provide an example where cross-refs
resolving is a really tough task - this sample shouldn't be the case where
one decides to resolve cross-refs in a legacy "spaghetti" set of projects
IOW we assume we're talking about experienced developers who prevent having
"cross-refs" spaghetti by doing code
clean-up/refactoring/de-cross-referencing once in a while within a project's
sources life-time...

John, it will pay itself back very quickly - just be patient - I'd guess
(based on your software development experience) it will need max one week
(in total) of your time to spend mastering that multi-project solutions -
and when you're there - only outer space will be your limitation...

Just create a very simple sample solution with several projects and try to
play with it setting references, moving custom classes from one project to
the other, changing namespaces, and using directives... it's really easy -
imagine hierarchical catalog where child entries can be referenced/accessed
from parent ones, but where sibling entries aren't aware of each other...
(if only they do not inherit from the same parent entries...) 

Thank you.

It seems like that may be what I am doing?  I have a single solution.  Inside of that solution's 
physical directory I have multiple projects, each in its own directory.  As I expand the solution I 
do an add / new project from the main solution / project.  Doing that takes care of creating a 
directory structure for each new project, but causes it to be created under the main solution directory.

Each project does not depend in any way on any other project, though I do have some shared 
libraries.  Each child project is referenced by the main project, but the child projects do not 
reference other child projects.

Now whether each of these independent projects ends up as individual applications I don't have a 
clue.  I was just tying them together with a single form / menu so that I have one central 
application to go to to find everything.

Thanks, but I am quite sure I would just get lost.  You have way too much faith in my C# abilities 
at this point in time.  ;)

I have found at least two dlls that can be referenced and used from C#.  Each claims to be "managed 
code" and make the source available, though what that is worth to me is not clear.  I just want

Hi Michael

Neither have I, but I googled a little on the "zubject" and several links tell that this GZip compression is not compatible with WinZip and the like because of missing file info, in other words it should be fine for compressing and decompressing a stream (which of course can be written/read to/from a file) but that's all.

A bit strange that this widely used function is missing from the framework.

Thanks, but I am quite sure I would just get lost.  You have way too
much faith in my C# abilities 
at this point in time.  ;)

I have found at least two dlls that can be referenced and used from C#.
Each claims to be "managed 
code" and make the source available, though what that is worth to me is
not clear.  I just want 
something that is easy to use and documented so I can figure out how to
use it.  I have a lot of 
uses for zip files, from zipping up archives of files for near line
storage to making true zip files 
for shipping to clients.

Even more strange that someone hasn't wrapped this into a C# class so that it is available as simple 
source.  Several DLLs out there.

Subject: [dba-VB] Do you wanna learn c#?
Message-ID: <4B25B4CE.9010105@colbyconsulting.com>

Have I got the book for you.

http://www.amazon.com/Microsoft%C2%AE-XNA%C2%AE-Game-Studio-3-0/dp/0735626588/ref=sr_1_2?ie=UTF8&s=books&qid=1260761698&sr=1-2

I bought this book because I found the XNA studio and wanted to learn all about how it works.  But 
this book is about teaching programming, and from that C#.  For anyone who knows vba or VB.net it 
will start off easy, but for anyone who doesn't program at all it also starts off easy.  This might 
be the best book for learning to program (in general) I have run into.  Plus it is fun.

You need Visual Studio (express is fine) and you need the XNA studio (it is also free).  An XBox 360 
game controller will be required pretty quickly.  I bought the cheapest controller for $15 from 
Wally world.

Then start reading (and writing).  I am on chapter 5 now (in about three days) and working on 
through it.

I swear you will learn C#, have fun while you are at it, AND learn how the XNA game studio framework 
works which is also an awesome tool.

Really folks, this is the real deal, if you have always said "I should..." do this one.  Or get your 
teenager involved in it.

I bought the book new from Amazon for about $20, plus the controller.  Everything else is free. 
That is a great deal folks!

I am working on creating a single field index on every field of a table.  I promptly ran into so 
many problems making it generic that I punted and went back to hard coding the database / table 
name.  I did find this:

select Name as FldName from psm11203.sys.columns
	WHERE object_id = OBJECT_ID('PSM11203.dbo.tblOrderData')

Which does give me a table of field names.  Using this in a cursor I am then able to create an index 
on each field, so I am off and running.

This is really a one off process that I need to run on my tblHSID - the table from hell from the 
database from hell.

I have to tell you I am a bit hesitant to pull the trigger in this for the table from hell.  It is 
going to take many minutes to build each index and there are well over 500 fields to index.  I could 
end up locking up my database for the next month.  ;)

I did create a copy, created a clustered index and will be creating all of these indexes on that 
copy, but even then it pretty much uses all of the resources of the server.

Subject: [dba-VB] A Parameters syntax question
Message-ID: <c09.73631826.3858baa7@aol.com>

 
Hi All
 
I'm connecting a vb2005 DataGridView to an Access db via vb code to  return 
a subset of records from a table. Using the GUID dataType it works fine  
but when I change the datatype I get all the records.
 
I'm using the Imports system.Data.OleDb class. From there I have OleDb  
connection, Command, DataAdapter and a Dataset.
 
EG.
With Command
    .CommandText = "QueryName"
    .CommandType = CommandType.StoredProcedure
    .Connection = OleDbConnection
    .Parameters.Add("@REFNOC", OleDbType.Guid,16).Value  = New Guid(REFNOC)
end With
 
Every thing works as it should. That is until I change the the datatype in  
the Parameter line and try to use a string or Integer.
 
I can't get the syntax right for the .Parameters line. If for example I  
change the .Parameter to say
 .Parameters.Add("@REFNOC", OleDbType.Single).Value = REFNOC I get all  
records
 
Can anyone cast a little light here?

When using parameters in vb.net connection one does need to specify  the

Then it works a treat

Subject: [dba-VB] windows 7 media center
Message-ID: <4B295D18.7070000@colbyconsulting.com>

Well my Vista Windows Media Center (WMC) finally bit the dust.  Something happened (a SP install I 
suspect) and the codec got trashed (I think) and suddenly WMC no workee - no tv of any kind, already 
recorded or off of the tv card.

As a college student I qualify to buy a copy of Windows 7 for $29 which sounded too good to pass up. 
  And that version supposedly had a much improved MCE.  So I did.  Bought it, and installed it ON A 
30 gb FLASH DRIVE last night.  Finished about 3:30 am.  She workee again.  In the meantime I also 
went from a low power dual core to a medium powered quad core, but twice the ghz rating.  Needless 
to say the Home theater PC flies.  Now if it will just work for a long time with no maintenance.

Hey John,

Did you install the SQL Client Tools?  I was just reading something about
this today.  I think the SMO stuff is installed with the client tools.  I am
not positive though.  If this does not solve your issue, I'll see if I can
find that reference tomorrow.

To all,

I use a lot of recordsets, and to detect they actually contain something I
have always used the following:

If myrecordset.bof=false and myrecordset.eof=false then
    do my stuff here
Else
    msgbox "empty"
End If

However my project manager prefers:
 If not myrecordset.bof and not myrecordset.eof then
    do my stuff here
Else
    msgbox "empty"
End If

Is there actually a prefered way, or is one quicker than the other, or is
there an even better way to do this ?

Thanks in advance for any comments, and a very merry christmas & happy new
year to everyone.

Hi Paul
Well I'll wait to be corrected but I reckon they're simply two syntactically
different ways of saying the same thing. They'd surely compile into the same
code. So it just comes down to preference of style and readability, i.e.
totally subjective

Or you could do this (which I prefer)

If not rst.eof then
Do my stuff
Else
Msgbox "who nicked my records"
Endif

Ps. Who is the programmer?  You, or the Project Manager?

Paul,

Perhaps better would be:

if MyRecordset.BOF and MyRecordset.EOF then
	msgbox "Empty"
else
	do stuff here
endif

It is easier to read the true than the nots, especially when there is more than one.  Either one 
works.  If this is in a tight loop and speed matters, then the NOT might cause a very slight 
slowdown as it is two extra boolean operators.  OTOH the compiler might just pick it up and rewrite 
it to my syntax anyway.

John,
I don't think that will work...something from Getz etc sticks in my
mind...might be old age though.

Paul,

Perhaps better would be:

if MyRecordset.BOF and MyRecordset.EOF then
	msgbox "Empty"
else
	do stuff here
endif

It is easier to read the true than the nots, especially when there is more
than one.  Either one 
works.  If this is in a tight loop and speed matters, then the NOT might
cause a very slight 
slowdown as it is two extra boolean operators.  OTOH the compiler might just
pick it up and rewrite 
it to my syntax anyway.

Hello John,

I have struggled with this value, and mixed it up with the connectionTimeout
also.  As a result, when I think there will be a delay, I also set it to
zero, and then I sleep easy.  I did that two years ago with
out troublesome app, and now it works and works and works.  Whats the
downside of infinite timeout.  If it takes three weeks, you will find out
anyway, but why kill it after ten mins when it would have finished
successfully in 19.45 minutes.

BTW how do you kill an executing stored procedure?

Hello John,

Not sure, but stopping the server is one way.  My main problems were sprocs
stopping when I did not want them to stop, for me, if it is still running
after 24 hours, it is probably never going to stop.  For you, you might
increase that to 48 hours, but in general, they either finish promptly, or
else will never finish, either way, timing out after 10, 20, 50, or even 600
minutes is almost never a good option, if there is a possibility that it
will finish in 601 minutes.

There is probably a way to stop a process, Francisco or some of the other
experts may know how, but I would either stop the db server / service, or
else in worst case, do a quick reboot.  For the rest of the year, I would
never worry about it, happy in the knowledge they the server must work till
the death :)

Thanks

Mark

Mark,

 >but I would either stop the db server / service, or else in worst case, do a quick reboot.

I have done both.  I have corrupted the database doing the reboot.  Stopping the service seems to 
work, however I have also seen the database pick up where it left off when the service restarted.

I am sure there is some way to "officially" stop a running process, I just don't know how.

Subject: [dba-VB] C# - Records Affected
Message-ID: <4B153F3A.8010102@colbyconsulting.com>

I am trying to get a count of records appended, updated etc in my SPs and returning that to my C# 
supervisor.  I am finding references to @@Rowcount however this is returning 1 instead of the actual 
number.

Is this @@RowCount the real deal?

The SP definition:

ALTER PROCEDURE [dbo].[sp_AZOut_AZExportToOrderedChunk]
	-- Add the parameters for the stored procedure here
	@DBName varchar(50),
	@ErrorDesc varchar(4000) output,
	@ErrorNo int output,
	@RecsAffected int output

AS
BEGIN


Setting the returned value

	EXEC (@SQL)
	select @RecsAffected = @@RowCount

My c# code:

intRecsAffected = sCmd.Parameters["@RecsAffected"].Value

The code triggers the try block if there is no such parameter (I just ignore it) or returns 1 if the 
parameter exists.

This is a functioning tested SP which typically appends millions of records, though the exact number 
depends on the database.

Is there something I need to know here?

<quote>
Do a select * from sysprocesses and identify the spid in question. Then do a "KILL 
<spidno>"

This will mark the spid as "dead". Note that it may take a while for the process to end as it 
has to rollback all the updates that it has been doing. Also kill only marks the process as 
dead - the process itself needs to check for this, and if it is stuck in a loop as the result of a 
bug or whateverthen it won't terminate. Also certain processes like dump and dbcc 
commands have significant code paths where the kill command is not checked for and so 
these can take some time to terminate.

Also, if the process is in an extended-stored procedure, or is waiting on network 
traffic/remote stored-procedure it will not check whether it has been terminated until these 
actions have been completed.

See Q171224 for more info - including details on the waittype that can tell you what a 
process is waiting on.

If the process won't die for one of the above reasons then your only choice is to stop the 
sqlservr.exe process itself and re-start.

Sorry for the ring, I found the problem.

The SP that I took this code from actually worked but the code I was testing did not and came before 
this code.  The problem was simply that in the SP I did not place the line that captured @@RowCount 
immediately after the EXEC (@SQL) statement.

All of the examples clearly warned me that this was a requirement but you understand "senior moments".

Anyway, this is now working.

Piece by piece this thing is coming together.

Subject: [dba-VB] C# - Direct data manipulation
Message-ID: <4B159E83.4000006@colbyconsulting.com>

As previously mentioned, over the last couple of years I have built up a set of stored procedures 
which perform TSQL.  I then run sets of these stored procedures to perform processes.  The TSQL is

As an example a stored procedure might build a table, with boilerplate field names and data types, 
but a passed in database and table name.  Inside of the stored procedure I build up the correct SQL 
to create the table in the database specified, with the name specified.  Another stored procedure 
might create in index, with boilerplate field names, but a passed in database and table name.  Again 
the stored procedure builds up the TSQL statement to create the index in the correct db and table.

I already have these stored procedures debugged and working and have been using them in sets to 
perform "big picture processes" for quite some time, but the whole "execute a stored procedure" 
using a command object, parameter objects in a parameter array, interpreting the parameters etc just 
seems so... 1950s.  I feel like I am flipping switches on the front panel of a computer in a 50s 
sci-fi movie as a tape reel spins madly in the background.

Now that I am moving to C# I am wondering if this is required any more.  Can C# execute TSQL 
directly somehow?  Can I assemble this boiler plate plus database / table kind of thing into a TSQL 
statement directly in C# and then somehow tell SQL Server to execute that TSQL?  I understand the 
"SQL optimization" thing but it seems like (not sure here) that because the TSQL is dynamically 
constructed in the stored procedure, the whole "optimization" thing goes right out the window.  If I 
can execute TSQL directly from C#, what can I get back?  Rows affected?  Error codes?  And how?

As it stands I am happily flipping switches, tape reels whirring, exporting data for address 
validation.  This is good, I am happy, but ...

Hi John --

I must say I have never done that "dynamic" t-SQL via C# - I guess it should
be doable: using SMO or even SqlCommand's .ExecuteNonQuery(?) it should be
possible to create SPs and UDFs, and then execute them as usual...

BTW, UDFs, which return tables are very often a good substitute for all
kinds of temp tables and dynamic SQL...

I wonder what for all that "dynamism" there? 
Do you have constantly changing database structure?
Do you have constantly changing customer requests, which do not allow you to
create a set of stable parameterized SPs and UDFs, and for small(?) changing
part of queries use LINQ for SQL or ADO.NET EF?

Thank you.

Hi John

As I see it, that would be LINQ and ADO.NET EF (Entity Framework). Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you. Critics tell that this SQL could be long-winded (= not optimized) but what do I care? If it flips 17 or 87 switches does nothing to me as long as the result is fast and precise.

ADO.NET EF is an amazing piece of work. It is not mature but if MS continues to evolve it with the same speed as Silverlight I'm sure it will catch up.

Message-ID: <c7fd28d00912020223q1c3e0388sec97ee600fd01dd2@mail.gmail.com>

Hello All,

I am running VS 2008 on a powerful machine with loads of resources.  My
project is a DNN project sitting in the wwwroot folder which allows me to
change a few lines of code and then immediately see the results in the web
app.

However, when I manipulate the Data Context Objects in the AppCode Folder,
the response times are dreadfully, slow.  It takes three to four minutes to
open, edit, save and close one of these objects.

I have tried it on a second machine and the results are similar.

I can edit the Dbml files outside of the solution, but I am not sure whether
that is safe to do so, when I edit them outside the solution (copying and
pasting to another folder and then opening the dbml file from there), they
open instantly.  When I say "safe to do so", does the project file or the
sln file need to be updated with the changes that have been made.  I do get
some warning message about "cannot find web.config, so using the file from
the dbml file instead" which I accepted.

I recall Shamil mentioned that manually editing these within the individual
files is not a good idea, so i guess that he may have been suffering the
same problems as I am, IE so sloooow to open and close.

TIA for an help, if I have not expressed the problem clearly enough, let me
know,

Mark

Hello Mark --

First of all try to switch to FireFox - forget IE while debugging large
ASP.NET apps from within VS....

I  can only note that debugging large ASP.NET applications is a real PITA -
this is why I'm always trying to get out as much as possible BL and DAL code
into separate projects and develop, debug/test them without UI (ASP.NET or
WinForms or WCF)...

And DNN is a "huge ASP.NET" app with a lot of classlibs, which are so
tightly coupled together that there is no way to debug part of them outside
of running DNN instance - with all the consequences - bad luck...

I suppose you can edit DNN's Data Context Objects source code from AppCode
outside of VS (e.g. within notepad) - when the edits are saved then DNN will
restart, that could take a while, quite a while....

A temp solution could be to keep *all* the source code of DNN module's
control within that control's code behind .aspx.cs (.aspx.vb) during
development - when you edit your code there then ASP.NET app will not
restart it will just recompile .aspx and .aspx.cs - so it should work
considerably quicker...

All in all I think DNN custom modules development is a RPITA - one can never
know how much it will finally take for a given project if they will not try
to find a way to debug/ test as much as possible code outside of running
DNN: something like develop a separate ASP.NET application, make it working
and then port it to DNN environmnet...

Be prepared for "crazy debug sessions" (if I'm  not missing something and
there are some "miracle" tools, which simplify DNN custom development
debugging)...

Philosophic note: DNN seems to be a good example that there "are no miracles
in this world" - DNN is a great prototyping tool and CMS, when one has ready
to use DNN modules and skins, and DNN is becoming RPITA when one have to
develop a(n) (advanced) custom module. Rhetoric Question: Why in this world
there couldn't be a "silver-bullet" tool able to support both standard and
custom development with the same ease as DNN does support CMS development?

I guess "Ruby on Rails" could be "what doctor ordered"?...

Or ASP.NET MVC2 Framework?

DNN did grow from a "junky" MS ASP.NET sample code base, and even advanced
developers as DNN Core Development Team members are can't still "convert"
that original "junk" to pearls...

Hopefully they will do that in DNN v.7? - they "just" need to clean-up DNN
huge code base and to implement what is called "Inversion of Control"
(http://martinfowler.com/articles/injection.html) to "untight" DNN Core
classlibs as much as possible...

Please correct me if I'm wrong - in fact I'd be really happy to be wrong
here as I have had to suspend one of the DNN projects, which didn't go
smoothly because of PITA DNN custom modules development experience...

Sorry, Mark, I have no a definitive answer for you here - just some "soap"
and "bubbles" and PITA of my own DNN custom modules development experience,
which I need to find a way to workaround, or quit the idea of DNN custom
development completely as it's too expensive to be true. Still hope I missed
some approaches to simplify this development - I mean ready to use
approaches and tools without long learning curve...

Thank you.

Hello Shamil,

Thank you for your detailed response.

*Browsers*
Some comments, I am actually using Chrome to View my work, but I am not
doing any debugging, in the traditional sense, I code a few lines, click
save and then view the results in Chrome, when I am not happy, I flick back
to VS, change it and continue again.  So, it is true to say, I am not really
debugging, just viewing.  However, I stopped using IE a few years ago, and
since I switched to Chrome, it is the first thing I install on new machines.
 With the exception of the MSDN site, it works perfect for me.


*Slow Data Contexts*
So can I assume that this slowness is simply to be accepted, it is either a)
the way VS2008 usually performs, or b) the way VS2008 performs when data
contexts are involved in a large project such as DNN.  I did not notice any
difference when I copied the code from the wwwroot folder, so I hope that is
not part of the problem.

*DNN Development*
Probably I am not doing real DNN custom programming, but I am currently
building web user controls, and simply saving them, and then creating a
module for DNN and including the web user control on that module.  I know
this is not real DNN programming, but have created about 20 module so far
like this.  DNN gives me, as a script kiddie type programmer, they ability
to do a simple web app, but it manages the users and authentication,
something that I could never program.

IOW, with the exception of a few DNN hooks, I am doing simple programming,
but throwing the results into DNN.


*Free Lunch*
I have to say I agree with you, there are limitations everywhere.  My
appoach is always to keep it as simple as possible until I absolutely know
that I need to make it more complex.



Thanks,

Mark

Hello Shamil,

Thank you for your detailed response.

*Browsers*
Some comments, I am actually using Chrome to View my work, but I am not
doing any debugging, in the traditional sense, I code a few lines, click
save and then view the results in Chrome, when I am not happy, I flick back
to VS, change it and continue again.  So, it is true to say, I am not really
debugging, just viewing.  However, I stopped using IE a few years ago, and
since I switched to Chrome, it is the first thing I install on new machines.
 With the exception of the MSDN site, it works perfect for me.


*Slow Data Contexts*
So can I assume that this slowness is simply to be accepted, it is either a)
the way VS2008 usually performs, or b) the way VS2008 performs when data
contexts are involved in a large project such as DNN.  I did not notice any
difference when I copied the code from the wwwroot folder, so I hope that is
not part of the problem.

*DNN Development*
Probably I am not doing real DNN custom programming, but I am currently
building web user controls, and simply saving them, and then creating a
module for DNN and including the web user control on that module.  I know
this is not real DNN programming, but have created about 20 module so far
like this.  DNN gives me, as a script kiddie type programmer, they ability
to do a simple web app, but it manages the users and authentication,
something that I could never program.

IOW, with the exception of a few DNN hooks, I am doing simple programming,
but throwing the results into DNN.


*Free Lunch*
I have to say I agree with you, there are limitations everywhere.  My
appoach is always to keep it as simple as possible until I absolutely know
that I need to make it more complex.



Thanks,

Mark

Shamil,

As I have discussed in the past, the business is doing the exact same process to many different 
tables.  Because of the size of these tables and the processing involved I find it useful to store 
each table in it's own database.  These are just lists of names, each list comes from a different 
source and is called something by the client, something that makes sense to him.  These lists (a 
table) will always be millions of names / addresses, and often are 50 million or more.  When you 
have 50 million names, the database, with just this one single table will be 10 or 20 gigabytes. 
Once you start processing it can mushroom to 50 gigabytes.  Thus storing a dozen of these tables in 
a single database just doesn't make sense (to me).

Thus I have a dozen different databases.

I have to apply all of these stored procedures to each one of these databases once a month.  Thus 
write the stored procedure such that I can pass in a database name and a table name.  Voila, the SP 
works for all of my databases.  But that means dynamic SQL.  I really don't have an issue with 
dynamic SQL, although I have witnessed first hand the time required for SQL Server to do the 
"compile" - creating the execution plan.  If I run the SP a second time with the same db and table 
name the time to execute drops sharply.

BTW, these lists become the source for "orders" of names.  Each of these orders also are stored in 
its own database, and I have to execute these same (or similar) SPs against each of these orders. 
Over the last 4 years I have perhaps a hundred of these order databases.

This is what I do for this client, create these databases, and apply processes against these 
databases.  The processes are exactly the same across all of the databases, thus having a stored 
procedure that performs some part of that process but can be applied to any of these databases makes 
sense (to me).

I have spent the last five years performing these processes entirely manually, then one by one 
creating a stored procedure to automate one of the steps, then the next step, and the next.  By now 
I have an entire master library with (let me go check) 42 different stored procedures that, taken 
together, automate my work for the client.

THAT is the point of the C# side of things.  Automating the automation so to speak.  Taking these 42 
stored procedures and stringing sets of them together, 7 which perform the output of data to an 
external program for processing, 6 more that get the processed data back in, a half dozen more that 
perform some other processing, another set that do order processing, etc.

This is not a bank, or a company or a call center or a manufacturer, or any of the other "typical" 
SQL Server databases.  It is name / address list processing and creating orders from these lists. 
Really pretty simple but extremely painstaking.  And like anything else we do, I can't be making 
mistakes, it must be done in a specific manner, a specific sequence, EVERY time.

Subject: [dba-VB] Read XML File Using xsd Schema File
Message-ID: <38c884770912020805s570c99e1ia753bf4f81b4d0f7@mail.gmail.com>

To all,

We have been a given what looks to me like a fairly complex XML file, we
have also been given a xsd schema file.  I tried using the SQLXMLBulkLoad
object in VB6 and was getting the error

Schema: relationship expected on 'Company'.

The company that gave us both the files insist that the xsd is correct
(according to my project manager).  I downloaded and installed Stylus Studio
2010, with which I loaded the XML, and then generated my own xsd schame
file.  Tried again and this time get the same error as above, but instead of
'Company' the error was 'Groups'

The VB6 code I am using is as follows:

Dim objBL

Set objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad")
objBL.ConnectionString = "Provider=SQLOLEDB.1;Password=hermes;Persist
Security Info=True;User ID=sa;Initial Catalog=XLTestCD;Data Source=AL-SQL1"


objBL.KeepIdentity = True

objBL.errorlogfile = "C:\XML_StylusStudio\Error.log"

objBL.checkconstraints = True
objBL.xmlfragment = True
objBL.schemagen = True
objBL.sgdroptables = True

objBL.Execute "C:\XML_StylusStudio\newschema.xsd",
"C:\XML_StylusStudio\CDFull_Original.xml"
Set objBl=Nothing

The object of the exercise being that we generate related tables in SQL
Server 2005 of the XML data.

Would be grateful if anyone could help with this (would be happy to send
example XML file and the schema offline), as I haven't got much hair left to
pull out.

Thanks in advance for any help on this.

Hi John --

Thank you for your reply.

Do you use your different databases for data input, or you also have to
update those different databases' tables?

Hi John

As I see it, that would be LINQ and ADO.NET EF (Entity Framework). Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you. Critics tell that this SQL could be long-winded (= not optimized) but what do I care? If it flips 17 or 87 switches does nothing to me as long as the result is fast and precise.

ADO.NET EF is an amazing piece of work. It is not mature but if MS continues to evolve it with the same speed as Silverlight I'm sure it will catch up.

As previously mentioned, over the last couple of years I have built up a set of stored procedures 
which perform TSQL.  I then run sets of these stored procedures to perform processes.  The TSQL is 
always dynamic.

As an example a stored procedure might build a table, with boilerplate field names and data types, 
but a passed in database and table name.  Inside of the stored procedure I build up the correct SQL 
to create the table in the database specified, with the name specified.  Another stored procedure 
might create in index, with boilerplate field names, but a passed in database and table name.  Again 
the stored procedure builds up the TSQL statement to create the index in the correct db and table.

I already have these stored procedures debugged and working and have been using them in sets to 
perform "big picture processes" for quite some time, but the whole "execute a stored procedure" 
using a command object, parameter objects in a parameter array, interpreting the parameters etc just 
seems so... 1950s.  I feel like I am flipping switches on the front panel of a computer in a 50s 
sci-fi movie as a tape reel spins madly in the background.

Now that I am moving to C# I am wondering if this is required any more.  Can C# execute TSQL 
directly somehow?  Can I assemble this boiler plate plus database / table kind of thing into a TSQL 
statement directly in C# and then somehow tell SQL Server to execute that TSQL?  I understand the 
"SQL optimization" thing but it seems like (not sure here) that because the TSQL is dynamically 
constructed in the stored procedure, the whole "optimization" thing goes right out the window.  If I 
can execute TSQL directly from C#, what can I get back?  Rows affected?  Error codes?  And how?

As it stands I am happily flipping switches, tape reels whirring, exporting data for address 
validation.  This is good, I am happy, but ...

Shamil,

I receive lists of names in CSV or fixed width files.  I import those into SQL Server, creating a 
PKID in the process.  I then have to export the PKID plus the name / address monthly for address 
validation.  Once validated, I have to import the data back in.  This is the monthly process. 
Approximately 1% of all the people on any given list move each month.  So I have to go back in to 
the original list and update 1% of the addresses, or simply swap out the new list (table) for the 
old.  There is never any manual processing of individual names inside of these lists, IOW people 
never look at them, modify them, add new ones, delete address or anything like that.  The list is 
"stable" in that regard.

These lists become the source for orders of names.  Orders are a whole 'nother process, but also use 
SPs to do their thing.

John --

Have you tried to use MS SQL database filegroups and partitioned tables &
views?

http://msdn.microsoft.com/en-us/library/ms345146(SQL.90).aspx

With them I suppose only initial import/insert of data have to be
parameterized with table name, and the rest can be done without any dynamic
T-SQL. Please correct me if I'm wrong.

Please note I'm not trying to "force" you to change your current working
solution - just wondering is there a legal way to solve your task without
dynamic T-SQL...

the original list and update 1% of the addresses, or simply swap out the new
list (table) for the 
old.  There is never any manual processing of individual names inside of
these lists, IOW people 
never look at them, modify them, add new ones, delete address or anything
like that.  The list is 
"stable" in that regard.

These lists become the source for orders of names.  Orders are a whole
'nother process, but also use 
SPs to do their thing.

Shamil,

I have not.

All of that is rather esoteric stuff for a non DBA.  My job is processing data, and that is only a 
small part of my job, i.e. this is only one of many clients, and the only one that needs this kind 
of SQL Server stuff.

As I have said many times, if my job was to go into a company every day and play DBA then I would 
learn many more things SQL Server related.  As things stand I learn just enough to make things work, 
and a LITTLE extra in search of efficiency.  It is certainly not that I don't want to, I just don't 
have the time.

In the end I find the method I use comfortable from many angles.  I have to do some things that 
require creating views, other "processing" tables and so forth.  It really just works (for me) to do 
things this way, have separate databases to hold all of the "junk" associated with each list.  Kind 
of the old "encapsulation" thing.

Your suggestion would of course end up with all tables inside of a single "database", and as such 
the need for the Database parameter would go away but I still have to do the same thing to many 
different tables.

Again, could this be done by one of the experts on the SQL Server list.  Probably!  Will I ever get 
there?  Uhhhh doubtful.

Hi John --

OK. Don't break it with implementation of other approaches if it works...

Just for the future projects - I suppose (I might be missing something as I
do not have that experience but I plan to try, maybe within our
Northwind.NET project) this partitioning stuff is just practical for the
tasks as you do (similar stuff was available for non-relational DBMSs in the
end of 70-es/beginning of 80ies, and for Oracle it's available for years now
AFAIHH), and this stuff doesn't take that much time to learn (one day?)  and
use (a few short reusable T-SQL scripts?) that it would  take to program and
to test and to support dynamic T-SQ: for many SPs and UDFs...

Thank you.

Hi Dan and Doug,

If that stats will help you to quote and to plan your projects, please write
a short note to be posted there (myself or Gustav can post it)

http://northwind.codeplex.com/Thread/View.aspx?ThreadId=54924

This project is currently in suspended state, and good feedback might help
to plan and to implement some useful follow-ups.

Thank you.

Hello Shamil,

In VS2008, when I create a folder in app_Code, and then create a new Linq to
SQL Class is it assigned the extention of dbml, default name is
DataClasses.dbml

It is these classes that are sooo slooow to do anything with.  I timed the
time it takes to just click create, drop a table onto the design surface,
and then click save.  It is taking 4 minutes to do that, so when I needed 20
- 25 objects or so, I have to sit like a donkey and click for almost two
hours.

It still takes four minutes to open and edit one.

A PITA for sure.

If I open the class as a standalone file, I can operate with
instant performance, but it does not play well with the project/ solution.

I have to say, I wish I knew more about these data classes and how they
really should be used in real world applications.

Thanks

Mark

Hello Mark --

OK, I suppose you can create custom DLL(s) working with LINQ to SQL in a
solution outside of your custom DNN solution, and then just use your custom
DLL within custom DNN solution - your LINQ to SQL objects from DLL should be
public and this DLL should also have its own config file...

I have done something like that but with POCO-objects
(http://en.wikipedia.org/wiki/Plain_Old_CLR_Object), which I used as
ObjectDataSources for web forms within DNN custom solutions' custom
modules...

Thank you.

Hello Shamil,

I guess this is an option for me, but to be honest, it will probably more
easier  for me to take the delay of waiting that attempt to manage the
additional layer of complexity.  As with all things in life, I suppose if I
take the time to review this, it will save me time, but I am afraid to spend
a day on it only to save myself a few minutes a few times a day.

Thanks any way for the suggestion,

Mark

I want to create application settings for things like the server instance that the program will bang

Create an xml file called UserSettings (or whatever) and store each value in a node in that.  Then all you have to do is read them back when you need them.  We use several of these, one called OLEDBSettings.xml that looks like this: 

  <?xml version="1.0" standalone="yes" ?> 
- <NewDataSet>
- <connection>
  <dbtype>0</dbtype> 
  <provider>Microsoft.Jet.OLEDB.4.0</provider> 
  <datasource>C:\Documents and Settings\All Users\Application Data\Infostat\RIMDrill\5\RIMDrillData.mdb</datasource> 
  <userid>RIMUser</userid> 
  <password /> 
  <initialcatalog /> 
  <trusted>false</trusted> 
  </connection>
- <connection>
  <dbtype>1</dbtype> 
  <provider>sqloledb</provider> 
  <datasource>infoserver</datasource> 
  <userid /> 
  <password /> 
  <initialcatalog>RIMDrillDataSQL</initialcatalog> 
  <trusted>true</trusted> 
  </connection>
  </NewDataSet>

We actually have a file like this for each application and it lives in the application folder.  This is just to give you an idea, not a how to.   We have a class that wraps this in our apps and uses this kind of routine to read it.  I leave it up to you to translate to C#.

    Shared ds As DataSet
    Shared _connectionString As String

    Shared _xmlPath As String = "OLEDBSettings.xml"         'default to xml file in apppath

   Private Shared Sub ReadSettingsFile()
        If IO.File.Exists(_xmlPath) Then
            Call CreateSchema()
            ds.ReadXml(_xmlPath)
            Call DecryptPassword()
            _connectionString = GetConnectionString()
        Else
            If ds.Tables(0).Rows.Count = 0 Then
                'placeholder for jet settings
                Dim row As DataRow = ds.Tables(0).NewRow
                row("dbtype") = 0
                row("provider") = "Microsoft.Jet.OLEDB.4.0"
                ds.Tables(0).Rows.Add(row)

                'placeholder for sql settings
                row = ds.Tables(0).NewRow
                row("dbtype") = 1
                row("provider") = "sqloledb"
                ds.Tables(0).Rows.Add(row)
            End If
        End If
    End Sub

  Private Shared Sub CreateSchema()
        ds = New DataSet
        Dim table As New DataTable("connection")
        table.Columns.Add("dbtype", GetType(Integer))
        table.Columns.Add("provider", GetType(String))
        table.Columns.Add("datasource", GetType(String))
        table.Columns.Add("userid", GetType(String))
        table.Columns.Add("password", GetType(String))
        table.Columns.Add("initialcatalog", GetType(String))

        table.PrimaryKey = New DataColumn() {table.Columns("dbtype")}

Hi Charlotte,

I see this as useful, but,
If you need a complex setting structure why not just create a
'MySettings' class and serialise or deserialise it as needed?
I think John has already worked with the Serializable attribute.
Am I missing something?

Cheers

Hi John

Yes and no. I used an old version for some time but the current version is more powerful.

Please note that it comes with all the examples from his book, and even without the book this is a great why to get your hands on LINQ as the code is "live" - no need to copy and paste, it is right there for you try out at once.

Message-ID: <sb18eda8.001@cactus.dk>

Hi John et all

Further to the notes below on Joseph Albahari's LINQPad, it contains a link to download all the example code from "LINQ in Action".
Also, it has a link to this amazing demo of the power of LINQ:

http://blogs.msdn.com/lukeh/archive/2007/03/19/using-linq-to-solve-puzzles.aspx 

It's a true eye-opener and a good example showing that the scope of LINQ is much wider than "normal" database querying.

The code is included in LINQPad when downloaded, ready for you to play with at:

  Tab Samples, 
  C# 3.0 in a Nutshell, Chapter 9 - LINQ Operators, Joining, Extra - Weights Puzzle. 

It's Friday and soon weekend!

Subject: [dba-VB] Read XML File Using xsd Schema File
Message-ID: <38c884770912040419xdc61c66y2c315b820cd6fb09@mail.gmail.com>

To all,

We have been a given what looks to me like a fairly complex XML file, we
have also been given a xsd schema file.  I tried using the SQLXMLBulkLoad
object in VB6 and was getting the error

Schema: relationship expected on 'Company'.

The company that gave us both the files insist that the xsd is correct
(according to my project manager).  I downloaded and installed Stylus Studio
2010, with which I loaded the XML, and then generated my own xsd schame
file.  Tried again and this time get the same error as above, but instead of
'Company' the error was 'Groups'

The VB6 code I am using is as follows:

Dim objBL

Set objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad")
objBL.ConnectionString = "Provider=SQLOLEDB.1;Password=hermes;Persist
Security Info=True;User ID=sa;Initial Catalog=XLTestCD;Data Source=AL-SQL1"


objBL.KeepIdentity = True

objBL.errorlogfile = "C:\XML_StylusStudio\Error.log"

objBL.checkconstraints = True
objBL.xmlfragment = True
objBL.schemagen = True
objBL.sgdroptables = True

objBL.Execute "C:\XML_StylusStudio\newschema.xsd",
"C:\XML_StylusStudio\CDFull_Original.xml"
Set objBl=Nothing

The object of the exercise being that we generate related tables in SQL
Server 2005 of the XML data.

Would be grateful if anyone could help with this (would be happy to send
example XML file and the schema offline), as I haven't got much hair left to
pull out.

Thanks in advance for any help on this.

Hi John

Oh, I misunderstood you.
Not until recently. Skipping the SQLCommand low-level stuff completely, I've used datatables with in-line SQL queries (to avoid designing T-SQL and special views - Shamil mobbed me for that choice!) and I have been busy learning just these - so one step further, no thanks. Also, I had a hard time grasping the lambda expressions and syntax and still feel I have a lot to learn. Yes, you can use LINQ without lambda, but that seems like LINQ without an arm and a leg. But - for anything else than some special cases like perhaps your cases - I'm confident LINQ is the route to follow.

Not that I have used these in a scenario even "remotely close" to yours, but the fine thing is that is performs all the plumbing behind the scene - generates the SQL for you. Critics tell that this SQL could be long-winded (= not optimized) but what do I care? If it flips 17 or 87 switches does nothing to me as long as the result is fast and precise.

I have to say that as a developer of a higher level language, I can see where avoiding TSQL would be 
  something we would try to do.  While I understand that SQL Server can be integrated into and used 
straight from the VS environment, most of us come at it from the built-in editor which frankly 
sucks.  And I mean REALLY BADLY sucks, no apologies to our admin friends.  I guess I have been doing 
SP development for a couple of years now and I still hate the built-in editor.  And yet... that is 
what I use.

IMHO this is an area where MS has fallen down on the job.  If this integration thing is so darned 
simple, then MS should push education, seminars, books, education, education to get us working in VS 
to run (program) SQL Server.  From a development perspective, and that is what SPs and UDF are after 
all, SQL Server should just be a tool used to manipulate data, NOT a dev environment.

Over the last month I have found two APIs that allow C# to do a ton of stuff directly in SQL Server. 
  WAY COOL stuff, but you would think it was porn the way you don't see it in the mainstream.  These 
APIs allow you to manipulate SQL server the same way you can manipulate any other object - create, 
delete, observe, modify, manipulate anything in SQL Server - straight from VS.  But where are the 
forums, the blogs, the developer excitement?  It appears to me that there is a very real "here is 
your database" aimed at the developers who use SQL Server, and the admins just do things the way 
they always have for the last 20 years.  And they buy tools from the RedGates of the world who 
undoubtedly do salivate over these new APIs.

Just my humble opinion.

Hi John

One reason could be that many web developers know little about database design, thus they are being forced to leave that to a DBA. A chief developer once told at a tech meeting I attended, that they operated with the concept "scared of the database" meaning that the web developers should just be presented with ready-made views because SQL to these was like black magic.

I actually think that is a good thing, developers who just use data shouldn't need to be learning 
SQL Server to get their data.

That is really not the audience I am addressing however.  IMHO the built-in editor of SQL Server 
should either be removed entirely or at least brought into the current century.  It is notepad with 
pretty colors.  How many millions of man hours have been wasted trying to track down errors when the 
only error message presented was "error near (insert some unrelated thing here)".  Why bother even 
throwing up an error like that, and that is 99.9% of the errors I have EVER seen in two years 
working with SQL Server.

Notepad, with pretty colors.

For all of the rude comments us Access developers get about Access being "a toy", the code editor in 
Access is in a complete other galaxy from the code editor in SQL Server.  SQL Server editor looks 
like it was designed in 1986 and never upgraded.

Of course with the "real men don't use code editors" mentality of the DBA side of the fence I can 
see why MS doesn't bother spending time on this.

Someday I really am going to have to figure out how to use VS to run / debug my SPs and stuff.  To 
me VS just seems over-the-top complex for the level of stuff I am trying to do.  An Access type of 
code editor would be just the right level of convenience and capability - built right into SSMS.

Hi John

LINQPad does pure SQL too, though not with IntelliSense, and error messages seem to be those from SQL Server.

Under the project is a properties object.  Double click that and an entire multi-tabbed dialog opens.

Click the settings tab.  There you will see a form where you can enter name, type, scope, value.

As far as I can tell this is a place where I (the developer) can create settings that my program 
will use and manipulate, settings (for example) to tell my program the name of the SQL Server 
instance to use in a connection string, the name of my control database where I store my stored 
procedures and UDFs.  Stuff like that.  Stuff that I am currently hard coding, but which really 
should be in a settings tab so that I don't have to remember where that constant is in code, I can 
just go to the settings tab to change.

My expectation is that there is an object somewhere in the .net namespace that allows you to do 
something like "Something.Somethingelse.Settings["MyServerName"]...." to access these things.

I expect to be able to create new ones, edit existing ones, delete them etc from a .Net object.  I 
am looking for that .Net syntax that allows me to do this from code.

Hi John,

You can access those properties using:

Properties.Settings.Default.{{PropertyName}}

Or

{{Root Namespace}}.Properties.Settings.Default.{{PropertyName}}

Hi John

Shamil is right, but that method is for reading only.
Please note that the Properties' collection object is read-only, thus it takes quite a few steps to add a property:

http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/c52b4fc6-66be-44ce-8a65-ab548f6f4f04

I have not used this as I haven't had any need to add properties on the fly. Reading and writing was fine for me, and new properties I added manually.

You may find it much easier and perhaps more convenient to just have a dataset which you read and write from/to an XML-file. I've posted code for this before.

Hi Gustav,

You can set 

Properties.Settings.Default.{{PropertyName}} = {{SomeValue}};

and save settings having "User" scope:

Properties.Settings.Default.Save();    

And they are saved not in {{ApplicationExecutableFileName}}.config, which
you deliver with you app's executable but anywhere else on your system -
probably somewhere in user's Application Settings - standard windows folder.
I have never had time to find out where settings are saved. Anybody?

Recap:

- settings are loaded from {{ApplicationExecutableFileName}}.config when you
deliver you application, and it runs first time;
- as soon as you save "User" scope settings they are saved in and loaded
from {{UnknownPlace}};
- if you move your application files into another folder on the same system
the settings are again loaded on first run from
{{ApplicationExecutableFileName}};
- ...

That looks confusing a bit but it's how it works...

You can click "Learn more about application settings..." on top right of
VS2008 application settings window available by Solution Explorer -> Project
name -> Right-Click -> Settings...

But if you wanted to have rather complicated structure of your application
settings file then better use your own custom XML files, which can be loaded
from/saved to files many ways without almost any coding...

Thank you.

Hi Gustav and all,

JC original request was "to access/modify" application settings AFAIU:
<<<
I want to create application settings for things like the server instance
that the program will bang on, the name of my database that I save my custom
UDFs and SPs in etc.  It is trivial to get there in the interface but Google
is not my friend tonight in discovering how to access / modify them through
code.

Hi Shamil

Well, much less hard-core than I had expected, indeed not a coding session but with a good perspective.
However, he came a long way describing and demonstrating many new features of VS2010, MVC and Silverlight. Also LINQ and ADO.NET EF seems to be mainstream. And, of course, much warmly promoting of Windows Azure which works very well together with VS, indeed with the new "local Azure" - a local simulator of Azure you can use during development so no live hosting is needed - much like the local web server that simulates IIS.

Very cool is the new GUI designer for Silverlight UI design. VS2010 is brushed up quite a lot with better support for multi-monitor use, improved IntelliSense and editing features in the code editor - everything is aimed at faster development with firm focus on you, the developer, very different from Access.
Further, the Team Foundation edition is now useful for single developers too, with unit testing, versioning etc. etc. However, I expect that to be available at a "corporate" charge only (beyond my budget), but let's see.

He promised to mail us links to the complete session and much more. I can post these here when they arrive.
If you or anyone else have questions to specific topics, Scott Guthrie may have touched, please ask.

Well, much less hard-core than I had expected, indeed not a coding session

However, he came a long way describing and demonstrating many new features

mainstream. And, of course, much warmly promoting of Windows Azure which
works very well together with VS, indeed with the new "local Azure" - a

OK, I am trying to reference

Properties.Settings.Default["ServerName"].ToString() and get the error

'System.Windows.Forms.PropertyStore' does not contain a definition for 'Settings' and no extension 
method 'Settings' accepting a first argument of type 'System.Windows.Forms.PropertyStore' could be 
found (are you missing a using directive or an assembly reference?)

OK, it appears that each project has its own set of properties.  If I set the same property in the 
current project's property set then

Properties.Settings.Default["ServerName"].ToString()

works just fine.

But that is not the behavior I want.  I need a SOLUTION property set, which appears to not exist? 
Which perhaps would explain why those who have done this before roll their own?

Does anyone have code to do this so I don't have to roll my own (a.k.a. reinvent the wheel) too?

Hi John

The file containing the settings is app.config.

To hold "global" settings you could create a small project with just this file and reference it from any other project.

My understanding of Properties.Settings is that settings must be by User
in order to be saved and the xml file will reside in the Local 
Setting/Applications
directory under the user's My Documents folder.

In that case, all projects under a solution could read a single xml file.

We decided to use cryptographic services for the i/o of the xml by
using an internal static class that reads/writes to a string collection
using methods we created like bof, eof, movefirst, addnew, etc.

Hi John --

For solution you can select one of the projects to be used to handle
settings.
That project is usually a core(utility/generic/settings) class library.
Then if you wish you can additionally wrap 

Properties.Settings.Default...

for every/most of the settings into your custom global (Solution scope)
properties' wrappers. Such wrapping makes your referencing projects
independent on actual implementation of handling of application settings.
When that done and works OK you can go and "reinvent the wheel" if needed
without any changes in referencing projects...

Subject: [dba-VB] C# - Thoughts on my methods
Message-ID: <4B1FC705.9010902@colbyconsulting.com>

As a consultant in a home office I work in total isolation except for this email group.  So I need 
your input, to keep me sane and to keep me on the right path.  I would like your thoughts on what I 
am doing and what I am intending to do.

As you know, I have "the database from hell", for which I am developing an application to allow me 
to manipulate the various pieces from an application interface rather than directly from stored 
procedures and the SSMS or from Access, which is what I have done to this point.  With C# I am able 
to do more than I was able from Access, including getting back output parameters from stored 
procedures.  So... my process so far.

First off, I am developing the overall application as a set of child projects inside of the 
application.  The main application opens a form with a menu, and that menu takes me to forms in the 
child projects to perform pieces of the application.  For example I have a database backup project 
where I can backup and restore specific databases or groups of databases.  I have an Accuzip project 
where I can export CSV files to and import resulting CSV files from the external Accuzip program.  I 
have an Orders project where I can create and manipulate the orders I create for the client.

Each child project is physically located underneath the main application directory.  In order to 
reference (open) the forms in the child projects, I have to set a reference to that project and I 
have to set a using statement in the form.  I still do not understand what these two pieces do.  Why 
do I have to set a reference and a using?  I assume you cannot set a using statement unless the 
project references the library (or project)?

I also don't understand why some objects in a referenced project class can be seen but others 
cannot.  IOW I can use one class in a namespace as a type to dimension an object, but another class 
in the same namespace is not visible, cannot be so used.

I don't understand a whole ton of things of this nature and I have to say that the whole "break into 
projects" idea is turning out to be more work than it might be worth.

Any comments on this email will be much appreciated.

Subject: [dba-VB] threading
Message-ID: <4B1FF708.1040700@colbyconsulting.com>

As mentioned in previous emails, I am developing an application to manage all of the tasks for the 
DBFH.  This includes Backing up databases, creating orders, transferring data between an external 
app etc.  I am trying to determine how to thread this app such that if I start a process exporting 
data to Accuzip, I could have another process importing data from Accuzip, and also be working on an 
order.

As things currently stand, each of these tasks is a project and each project has its own forms and 
classes, and anything else necessary for that task.  I really do want to be able to do multiple 
things like this at the same time.  Exporting data to Accuzip can take overnight, and actually 
consists of an export and a matching import process.  It makes perfect sense (to me) to have threads 
doing this kind of thing, and allow me to go back to the main application and do something else.

But at what level would I use a thread?  Would I use a thread to open the form that performs the AZ 
process?  This would allow me to get that started and immediately go back to the main app and open 
another form (using a new thread?) to start processing an order.

Or would the form open and the button on the form start a thread that executes the process?  If a 
form starts a thread, that allows the user (me) to do other things in that form potentially changing 
to a new directory or selecting a different database.  Do you disable all controls on a form when a

Hi John --

Why not have several (FE) applications if they are so independent? - all
developed within one VS solution but as separate (WinForms) projects sharing
the same (set of) class library(-ies)?

As mentioned in previous emails, I am developing an application to manage
all of the tasks for the 
DBFH.  This includes Backing up databases, creating orders, transferring
data between an external 
app etc.  I am trying to determine how to thread this app such that if I
start a process exporting 
data to Accuzip, I could have another process importing data from Accuzip,
and also be working on an 
order.

As things currently stand, each of these tasks is a project and each project
has its own forms and 
classes, and anything else necessary for that task.  I really do want to be
able to do multiple 
things like this at the same time.  Exporting data to Accuzip can take
overnight, and actually 
consists of an export and a matching import process.  It makes perfect sense
(to me) to have threads 
doing this kind of thing, and allow me to go back to the main application
and do something else.

But at what level would I use a thread?  Would I use a thread to open the
form that performs the AZ 
process?  This would allow me to get that started and immediately go back to
the main app and open 
another form (using a new thread?) to start processing an order.

Or would the form open and the button on the form start a thread that
executes the process?  If a 
form starts a thread, that allows the user (me) to do other things in that
form potentially changing

Hi John,

Have a look for DotNetNuke sources - they have free sources for
zipping/unzipping.
Those sources are used in core DNN functionality (modules setup) - IOW they
tested well, they are stable and thry work very well.

Hi John --

In fact this is easy (please correct me if I'm wrong):

- just reference your child projects from your main project and if you have
(sub-)child projects then reference them from child projects; you can also
reference child-child-(nephew) projects from parent projects etc... - just
avoid having circular references...

All that is very similar to MS Access/VBA references but unlike in MS
Access/VBA in .NET solutions this referencing always work without any
glitches whatever size your solutions are - tens of projects, thousands of
customer classes - no problems, no GPFs of Visual Studio (well, for ASP.NET
and WPF solutions you can have GPFs but even in that case you'll have all
your sources preserved).... 

<<<
I also don't understand why some objects in a referenced project class can
be seen but others 
cannot.  
>>>
That should be your problem/issue: in VS2008 (Prof) you can always try to
hint VS asking to "resolve" undefined class name, enum, global var - right
click -> Resolve... - if it can't do that - you can always do that manually
- but it may be needed to have some custom classes "shuffled" between your
projects...

<<<
the whole "break into 
projects" idea is turning out to be more work than it might be worth.

John, it will pay itself back very quickly - just be patient - I'd guess
(based on your software development experience) it will need max one week
(in total) of your time to spend mastering that multi-project solutions -
and when you're there - only outer space will be your limitation...

Just create a very simple sample solution with several projects and try to
play with it setting references, moving custom classes from one project to
the other, changing namespaces, and using directives... it's really easy -
imagine hierarchical catalog where child entries can be referenced/accessed
from parent ones, but where sibling entries aren't aware of each other...

Subject: [dba-VB] C# - Thoughts on my methods

As a consultant in a home office I work in total isolation except for this
email group.  So I need 
your input, to keep me sane and to keep me on the right path.  I would like
your thoughts on what I 
am doing and what I am intending to do.

As you know, I have "the database from hell", for which I am developing an
application to allow me 
to manipulate the various pieces from an application interface rather than
directly from stored 
procedures and the SSMS or from Access, which is what I have done to this
point.  With C# I am able 
to do more than I was able from Access, including getting back output
parameters from stored 
procedures.  So... my process so far.

First off, I am developing the overall application as a set of child
projects inside of the 
application.  The main application opens a form with a menu, and that menu
takes me to forms in the 
child projects to perform pieces of the application.  For example I have a
database backup project 
where I can backup and restore specific databases or groups of databases.  I
have an Accuzip project 
where I can export CSV files to and import resulting CSV files from the
external Accuzip program.  I 
have an Orders project where I can create and manipulate the orders I create
for the client.

Each child project is physically located underneath the main application
directory.  In order to 
reference (open) the forms in the child projects, I have to set a reference
to that project and I 
have to set a using statement in the form.  I still do not understand what
these two pieces do.  Why 
do I have to set a reference and a using?  I assume you cannot set a using
statement unless the 
project references the library (or project)?

I also don't understand why some objects in a referenced project class can
be seen but others 
cannot.  IOW I can use one class in a namespace as a type to dimension an
object, but another class 
in the same namespace is not visible, cannot be so used.

I don't understand a whole ton of things of this nature and I have to say
that the whole "break into 
projects" idea is turning out to be more work than it might be worth.

Any comments on this email will be much appreciated.

I have to point out that it is exceptionally easy to create circular references when the projects are set up like this.  That's why in our apps we keep all the forms in a project, all the reports in a project, etc.  Of course, if we were using libraries rather than projects under the solution, it would be different.  But this way, it can get messy fast.

You can roll your own using J# from within VS.  Idid that originally and it only takes minor translation to put it into C# or VB.  That said, we currently use Xceed.

Subject: [dba-VB] Ajax application problem
Message-ID: <3262DDC894CA427DB254732FCE5E70AF@VOSTRO>

Hi all,


I have problems putting an ajax application on a production server.

The application consists of an aspx page that keeps the javascript code.
This code talks with C# page methods to access Web services and interact with the database.

For example the first thing the user has to do is fill in login and password fields and click on the btnLogin.

Then the code execute the following command:
PageMethods.GetUser(user, onGetUserSuccess, onGetUserError);

with user being an array containing username and password. The C# GetUser webmethod returns its response to the onGetUserSuccess callback function.

The application runs ok on my dev pc.

I installed it on the production server, copying the aspx file, web.config file and the binary files.

When I run it, I get an error message, something like error during the handling of your request.(freely translated from french!!)

This error is displayed into a textbox by the onGetUserError callback function. 
I put an error trapping withing the webmethod, but its error message is not returned, leading me to think that this webmethod is not "entered".
Therefore the javascript code is running ok, but the call to the webmethod is failing.

I guess I missed to copy something like a javascript file from the framework, or something else.

Do you have any kind of experience in this regard?

NB: I also checked that the asp framework is of version 2.0 on the server, it's ok.

TIA,

Philippe Pons

Hi Charlotte --

Yes, it's easy to create cross-refs, and it's (usually) easy to solve
cross-refs under Visual Studio - please provide an example where cross-refs
resolving is a really tough task - this sample shouldn't be the case where
one decides to resolve cross-refs in a legacy "spaghetti" set of projects
IOW we assume we're talking about experienced developers who prevent having
"cross-refs" spaghetti by doing code
clean-up/refactoring/de-cross-referencing once in a while within a project's
sources life-time...

It seems like that may be what I am doing?  I have a single solution.  Inside of that solution's 
physical directory I have multiple projects, each in its own directory.  As I expand the solution I 
do an add / new project from the main solution / project.  Doing that takes care of creating a 
directory structure for each new project, but causes it to be created under the main solution directory.

Each project does not depend in any way on any other project, though I do have some shared 
libraries.  Each child project is referenced by the main project, but the child projects do not 
reference other child projects.

Now whether each of these independent projects ends up as individual applications I don't have a 
clue.  I was just tying them together with a single form / menu so that I have one central 
application to go to to find everything.

Thanks, but I am quite sure I would just get lost.  You have way too much faith in my C# abilities 
at this point in time.  ;)

I have found at least two dlls that can be referenced and used from C#.  Each claims to be "managed 
code" and make the source available, though what that is worth to me is not clear.  I just want 
something that is easy to use and documented so I can figure out how to use it.  I have a lot of 
uses for zip files, from zipping up archives of files for near line storage to making true zip files 
for shipping to clients.

I've never used it but there are builtin libraries for
zipping/unzipping.
Look in System.IO.Compression

The help file looks, well, helpfull for a change :-)

 > Have a look for DotNetNuke sources

Thanks, but I am quite sure I would just get lost.  You have way too
much faith in my C# abilities 
at this point in time.  ;)

I have found at least two dlls that can be referenced and used from C#.
Each claims to be "managed 
code" and make the source available, though what that is worth to me is
not clear.  I just want 
something that is easy to use and documented so I can figure out how to
use it.  I have a lot of 
uses for zip files, from zipping up archives of files for near line
storage to making true zip files 
for shipping to clients.

Hi Michael

Neither have I, but I googled a little on the "zubject" and several links tell that this GZip compression is not compatible with WinZip and the like because of missing file info, in other words it should be fine for compressing and decompressing a stream (which of course can be written/read to/from a file) but that's all.

A bit strange that this widely used function is missing from the framework.

Even more strange that someone hasn't wrapped this into a C# class so that it is available as simple 
source.  Several DLLs out there.

Have I got the book for you.

http://www.amazon.com/Microsoft%C2%AE-XNA%C2%AE-Game-Studio-3-0/dp/0735626588/ref=sr_1_2?ie=UTF8&s=books&qid=1260761698&sr=1-2

I bought this book because I found the XNA studio and wanted to learn all about how it works.  But 
this book is about teaching programming, and from that C#.  For anyone who knows vba or VB.net it 
will start off easy, but for anyone who doesn't program at all it also starts off easy.  This might 
be the best book for learning to program (in general) I have run into.  Plus it is fun.

You need Visual Studio (express is fine) and you need the XNA studio (it is also free).  An XBox 360 
game controller will be required pretty quickly.  I bought the cheapest controller for $15 from 
Wally world.

Then start reading (and writing).  I am on chapter 5 now (in about three days) and working on 
through it.

I swear you will learn C#, have fun while you are at it, AND learn how the XNA game studio framework 
works which is also an awesome tool.

Really folks, this is the real deal, if you have always said "I should..." do this one.  Or get your 
teenager involved in it.

I bought the book new from Amazon for about $20, plus the controller.  Everything else is free. 
That is a great deal folks!

I am working on creating a single field index on every field of a table.  I promptly ran into so 
many problems making it generic that I punted and went back to hard coding the database / table 
name.  I did find this:

select Name as FldName from psm11203.sys.columns
	WHERE object_id = OBJECT_ID('PSM11203.dbo.tblOrderData')

Which does give me a table of field names.  Using this in a cursor I am then able to create an index 
on each field, so I am off and running.

This is really a one off process that I need to run on my tblHSID - the table from hell from the 
database from hell.

I have to tell you I am a bit hesitant to pull the trigger in this for the table from hell.  It is 
going to take many minutes to build each index and there are well over 500 fields to index.  I could 
end up locking up my database for the next month.  ;)

I did create a copy, created a clustered index and will be creating all of these indexes on that 
copy, but even then it pretty much uses all of the resources of the server.

Subject: [dba-VB] A Parameters syntax question
Message-ID: <c09.73631826.3858baa7@aol.com>

 
Hi All
 
I'm connecting a vb2005 DataGridView to an Access db via vb code to  return 
a subset of records from a table. Using the GUID dataType it works fine  
but when I change the datatype I get all the records.
 
I'm using the Imports system.Data.OleDb class. From there I have OleDb  
connection, Command, DataAdapter and a Dataset.
 
EG.
With Command
    .CommandText = "QueryName"
    .CommandType = CommandType.StoredProcedure
    .Connection = OleDbConnection
    .Parameters.Add("@REFNOC", OleDbType.Guid,16).Value  = New Guid(REFNOC)
end With
 
Every thing works as it should. That is until I change the the datatype in  
the Parameter line and try to use a string or Integer.
 
I can't get the syntax right for the .Parameters line. If for example I  
change the .Parameter to say
 .Parameters.Add("@REFNOC", OleDbType.Single).Value = REFNOC I get all  
records
 
Can anyone cast a little light here?

Now then who's a silly boy!
 
When using parameters in vb.net connection one does need to specify  the 
parameter in the back-end query!!
 
Then it works a treat

Subject: [dba-VB] windows 7 media center
Message-ID: <4B295D18.7070000@colbyconsulting.com>

Well my Vista Windows Media Center (WMC) finally bit the dust.  Something happened (a SP install I 
suspect) and the codec got trashed (I think) and suddenly WMC no workee - no tv of any kind, already 
recorded or off of the tv card.

As a college student I qualify to buy a copy of Windows 7 for $29 which sounded too good to pass up. 
  And that version supposedly had a much improved MCE.  So I did.  Bought it, and installed it ON A 
30 gb FLASH DRIVE last night.  Finished about 3:30 am.  She workee again.  In the meantime I also 
went from a low power dual core to a medium powered quad core, but twice the ghz rating.  Needless 
to say the Home theater PC flies.  Now if it will just work for a long time with no maintenance.

A perfectly functioning application has all kinds of compile errors after the SQL Server install.  A

Hey John,

Did you install the SQL Client Tools?  I was just reading something about
this today.  I think the SMO stuff is installed with the client tools.  I am
not positive though.  If this does not solve your issue, I'll see if I can
find that reference tomorrow.

Message-ID: <38c884770912240409v7becad65te771430652a0472d@mail.gmail.com>

To all,

I use a lot of recordsets, and to detect they actually contain something I
have always used the following:

If myrecordset.bof=false and myrecordset.eof=false then
    do my stuff here
Else
    msgbox "empty"
End If

However my project manager prefers:
 If not myrecordset.bof and not myrecordset.eof then
    do my stuff here
Else
    msgbox "empty"
End If

Is there actually a prefered way, or is one quicker than the other, or is
there an even better way to do this ?

Thanks in advance for any comments, and a very merry christmas & happy new
year to everyone.

Hi Paul
Well I'll wait to be corrected but I reckon they're simply two syntactically
different ways of saying the same thing. They'd surely compile into the same
code. So it just comes down to preference of style and readability, i.e.
totally subjective

Or you could do this (which I prefer)

If not rst.eof then
Do my stuff
Else
Msgbox "who nicked my records"
Endif

Ps. Who is the programmer?  You, or the Project Manager?

Paul,

Perhaps better would be:

if MyRecordset.BOF and MyRecordset.EOF then
	msgbox "Empty"
else
	do stuff here
endif

It is easier to read the true than the nots, especially when there is more than one.  Either one 
works.  If this is in a tight loop and speed matters, then the NOT might cause a very slight 
slowdown as it is two extra boolean operators.  OTOH the compiler might just pick it up and rewrite 
it to my syntax anyway.

I don't think that will work...something from Getz etc sticks in my
mind...might be old age though.
