Message-ID: <DB7C1015741D45A48F326233AACC2606@nant>


Hi All --

Just wanted to share my experience in using .NET 4.0 Task Parallel Library
(TPL):

http://msdn.microsoft.com/en-us/library/dd460693.aspx

I have recently developed and released to a customer an advanced WinForms
project/application having running dozen of parallel tasks

- getting data from external data sources/web services and local lookup
databases, 
- coordinating data, 
- CRUD-ing results into MS SQL 2008 back-end and log file, 
- displaying progress on WinForm...

I have used .NET 4.0 C# and TPL - the following classes:

- System.Threading.Tasks.Task
- System.Collections.Concurrent.ConcurrentBag<T>
- System.Collections.Concurrent.ConcurrentDictionary<TKey, TValue>
- System.Threading.Barrier
- C# lock statement

and 

- System.ComponentModel.BackgroundWorker to activate and run the main thread
"talking to" WinForms UI via Invoke.

TPL and related data structures and classes help to significantly simplify
coordination of the parallel tasks execution, still programming of
coordinated parallel tasks' execution is rather advanced activity - plan
one-two weeks of "learning by doing" if/when you'll find you wanted to use
TPL in your projects...

Thank you.

Hi Gustav --

Thank you for your question - yes, the final result/experience is positive
- the application is now up&running 24x7x365 on customer's system - no
runtime errors, no memory leakage...

Although it took quite some efforts to make it working like that - be
prepared to spend one-two weeks of intensive development - just to learn and
master TPL development and catch and fix all kinds of "race conditions". It
happened I have had to write a tiny "framework" on top of TPL - that handles
initialization of TPL tasks, keeping and reporting status, logging, running
tasks asynchronously (main usage scenario) or synchronously (used for
testing) etc. This "framework" is not yet ready for sharing - maybe I will
share it "one fine day" if anybody proposes a composite sample task to be
split into, say dozen of subtasks to be run in parallel, which I can
implement using mentioned above tiny "framework" and publish for
reviewing...

BTW, I have started to read "Professional Test Driven Development with C#:
Developing Real World Applications with TDD"  by James Bender and Jeff
McWheter
(http://www.amazon.com/Professional-Test-Driven-Development-Applications/dp/
047064320X) and do agree with review you can find on Amazon - "It is one of
the best development books I have ever read and I highly recommend it" (I
personally do try to follow TDD approach for almost five years now - and it
works well for me amd my customers' projects (strict deadlines, "bad coding
habits", inertia etc. do disturb me to follow TDD "fanatically") but I have
never seen such a good, concise and practical book for .NET C# TDD
development - I second almost every word of it - I wish I had written one
like that :))

Thank you.

Hi Shamil

For a small project I recalled LightSwitch and wondered if it had moved anywhere.
It has, and has even been labeled Go Live. I guess it means some kind of improved level of support.

That took me a couple of minutes - and another couple to copy and paste the links and post these here.
Then I browsed the development pages a little and people and the team seem quite active.

But I still miss the time for testing ...

Subject: [dba-VB] SQL Server compression
Message-ID: <4E650719.7020301@colbyconsulting.com>

The other day I populated the second socket of my (AMD) server with another 8 core chip.  With cores 
to spare I decided to give compression a whirl.  I am finding a lot of stuff out there now saying 
that it reduces the I/O a ton and that if you are not cpu limited then it makes the database faster 
because more stuff fits into memory.  Basically the objective is to get as much of the stuff that is 
being actively used to stay resident in memory.

One immediate benefit is that it cuts the total size of my databases on disk roughly in half.  This 
is a good thing because I keep the major players on SSD which is expensive.  Keeping them compressed 
means that I have more room on the SSD.

When I got into this business in October 2004 I had servers with AMD single core 3.8 ghz and 4 gigs 
or RAM running x32 windows and sql server.  I was trying to run count queries on 100 gb databases 
and while it worked, it was... not fast. I would run counts that took a half hour.

Through knowledge acquired on these lists I rebuilt my database tables, learned indexing, and made 
the databases much more efficient.

Seven years later I have 16 cores and 32 gigs RAM running X64 windows and SQL server.  A year ago I 
bought 32 gigs of DDR3 1300 registered ECC ram for $1000.  Today I ordered another 32 gigs for $400.

It is incredible to me that using brute force and ignorance, I can now keep multiple largish 
databases entirely in memory.  While I have no benchmarks recorded to compare yesteryear to today, I 
am doing things in minutes or even seconds that would have taken me a half hour or even hours seven 
years ago.

These are exciting times.

BTW I found something called GeekBench which I ran on my machine.  It is the only thing I have found 
that is a reasonable cost ($13) to give me numbers to compare to others.  My Geekbench number is 
~13,500, and it pointed out to me that I am currently running the server with 1/2 of the memory 
"bandwidth" I could be getting (the biggest reason I am adding more).

I had 4 DIMMS and a single processor.  The processor has a 4 port memory controller.  When I added 
the new processor I redistributed the memory so that each chip had 1/2 of the memory (2 dimms) but 
in doing so I "crippled" the memory controller.  The price of memory is dropping like a rock so now 
seems like a good time to top up.  It will be interesting to see what filling out the memory 
controller does to the numbers.

I "retired" my previous server to be my VM server, and it just occurred to me that I can run 
Geekbench on that to get a comparison of my previous server against my current server.  My previous 
server is an AMD quad core with 16 gigs of RAM and the geekbench on that is 7469.

No one knows, and so many smart opinions out there about what is "dead" or "hot". 
MS claims that Silverlight will remain a focus product but who knows?

Neither Silverlight, LightSwitch, or Access for that matter, is the answer for everything, but I find LightSwitch to be much of that Access should have been.

Most smartphone users will have an Android. I have a Windows Phone 7 and find it superior.

Hi Gustav --

Yes, no one knows what technology will "fire" in the near future
I just noted I feel a bit "tired of custom MS technologies" - trying to make
money here using a limited (but huge - .NET framework IS huge) set of MS
technologies and to use as much as possible generally accepted software
development technologies, practices and standards...

BTW, I do plan to purchase Windows Phone 7/8 - if MS LightSwitch will be
able (isn't it yet?) to prototype/develop Windows Phone 7/8 apps I would
definitely try to use it...

Thank you.

The iPad doesn't support Silverlight any more than the iPhone does.  When
you arrive at a Silverlight web page, you get a message asking you to

Hi Doug,

Thank you - this is why I'm "talking HTML5/CSS3/JavaScript" here - iPad is
rather popular here because of the current Russian president using it.
I do "wild guess" Windows Phone 7/8 will be also popular here when its
localized version will be released still I have to take into account Android
and iPhone users when developing mobile apps...

Hi Shamil

The goal for LightSwitch is RAD of Silverlight Line Of Business apps for simultaneous deployment as desktop and browser application as you prefer. It is not (yet) for phone development as far as I know.

For Windows Phone development you currently use the development kit for Visual Studio 2010 and the associated Phone simulator.

The Gadgeteer looks cool but expensive. And a little more mechanics is needed if you ask me - to make the Meccano of our time.

3D printing I saw in real life at an exhibition several years ago and was amazed. It was used to create prototypes of items for later plastic molding. Items were relatively "coarse" at that time, but I'm convinced that this technique will turn many things upside down. Just think of how laser printing replaced offset print in many areas and how video projectors have killed old days' slide projector - and currently movie projection in cinemas.

The key parameter of 3D printing is, of course, the strength of the produced items. This evolves rapidly. At one point, think how you could bring a 3D printer and a bunch of printing powder to Mars, then you can produce any item locally. The list goes on.

Hi Gustav --

Yes, no one knows what technology will "fire" in the near future
I just noted I feel a bit "tired of custom MS technologies" - trying to make
money here using a limited (but huge - .NET framework IS huge) set of MS
technologies and to use as much as possible generally accepted software
development technologies, practices and standards...

BTW, I do plan to purchase Windows Phone 7/8 - if MS LightSwitch will be
able (isn't it yet?) to prototype/develop Windows Phone 7/8 apps I would
definitely try to use it...

Thank you.

P.S. ".NET Gadgeteer" and "3D printing" look very cool from here - imagine
one will be able to design and to "3d print" "home hand made" custom gadgets
in a few years:

"Gadgeteer utilizes the .NET Micro Framework to make writing code for your
device *as easy as* writing a desktop, Web or Windows Phone application."

Hi Shamil

No one knows, and so many smart opinions out there about what is "dead" or "hot". 
MS claims that Silverlight will remain a focus product but who knows?

Neither Silverlight, LightSwitch, or Access for that matter, is the answer
for everything, but I find LightSwitch to be much of that Access should have
been.

Most smartphone users will have an Android. I have a Windows Phone 7 and
find it superior.

Hi Shamil

For a small project I recalled LightSwitch and wondered if it had moved
anywhere.
It has, and has even been labeled Go Live. I guess it means some kind of
improved level of support.

That took me a couple of minutes - and another couple to copy and paste the
links and post these here.
Then I browsed the development pages a little and people and the team seem
quite active.

But I still miss the time for testing ...

Hi John

Not currently, but we do have a client with a heavily customized Access 97 application which we delivered summer 1999 and have expanded in steps through the years. This is for an organisation of dealers of agricultural machinery (combined harvesters, etc.) and as you can imagine, age is showing. It's not a question of reliability as the app has ran with zero errors or breakdowns. But new desktops we run with Windows 7 32-bit to avoid trouble with A97 and 64-bit OS, web interface is missing, etc. 

The office is only five people so budget is if not tight then limited and, as the app (three frontends actually with two backends for data and pictures) runs the full business, a replacement must be efficient and predictable to develop. However, the app contains nothing fancy - it's really a typical Line Of Business app taking care of everything a small organisation needs - exactly what LightSwitch is for.

So my plan is to model an introductory LS app to demonstrate how a single task could be performed and see if the client likes it. Then move on with a SQL Server 2008 backend (already running on their SBS).

If you should ask, we have no intention to move the app to Access 2010. I regard Access as a dead end for developers and the lack of a web interface other than SharePoint is a show-stopper.

Hi Gustav --

Why then not make it (3/n-tiered) WinForms application, and when it will be
really needed and so there will be funding for that UI work then make a
"fancy" 

- SilverLight,
- MS LightSwitch,
- Windows Phone 7,
- WPF,
- ASP.NET,
- "whatever else will be hot that time" ...

user interface?

IMO/in my experience developing WinForms apps with MS SQL 2008 FE is several
times/a matter of magnitude RAD-der than developing MS Access apps - and I
mean solid professional application development not "power-users toys". And
stability/flexibility/"multi-threadability"/scalability/... of 3/n-tiered
.NET applications is practically unlimited...

And you can develop 32-bit (WinForms) .NET apps and run them on 64 bit
systems with MS Access or MS SQL backend - just use corflags.exe
(http://msdn.microsoft.com/en-us/library/ms164699(v=vs.80).aspx)

Hi John

Not currently, but we do have a client with a heavily customized Access 97
application which we delivered summer 1999 and have expanded in steps
through the years. This is for an organisation of dealers of agricultural
machinery (combined harvesters, etc.) and as you can imagine, age is
showing. It's not a question of reliability as the app has ran with zero
errors or breakdowns. But new desktops we run with Windows 7 32-bit to avoid
trouble with A97 and 64-bit OS, web interface is missing, etc. 

The office is only five people so budget is if not tight then limited and,
as the app (three frontends actually with two backends for data and
pictures) runs the full business, a replacement must be efficient and
predictable to develop. However, the app contains nothing fancy - it's
really a typical Line Of Business app taking care of everything a small
organisation needs - exactly what LightSwitch is for.

So my plan is to model an introductory LS app to demonstrate how a single
task could be performed and see if the client likes it. Then move on with a
SQL Server 2008 backend (already running on their SBS).

If you should ask, we have no intention to move the app to Access 2010. I
regard Access as a dead end for developers and the lack of a web interface
other than SharePoint is a show-stopper.

Hi Shamil

I did consider that but funding will never be fat. The organisation counts only a few hundred members, and as the backends are only 150 MB I will face no scaling issue. It is exactly what LS is targeted for, so for this reason alone I will do the test. It may, of course, prove unsatisfactory in some way and if so I  will for sure choose the WinForms route which works very well for me.

We have one client where I have used the click-once deployment method and it works very well. Even the smallest modification, which I can code in minutes, gets deployed at once as it just requires a few default clicks and a password to the clients local FTP server and it has been published. It can't be easier and it just works.

Why then not make it (3/n-tiered) WinForms application, and when it will be
really needed and so there will be funding for that UI work then make a
"fancy" 

- SilverLight,
- MS LightSwitch,
- Windows Phone 7,
- WPF,
- ASP.NET,
- "whatever else will be hot that time" ...

user interface?

IMO/in my experience developing WinForms apps with MS SQL 2008 FE is several
times/a matter of magnitude RAD-der than developing MS Access apps - and I
mean solid professional application development not "power-users toys". And
stability/flexibility/"multi-threadability"/scalability/... of 3/n-tiered
.NET applications is practically unlimited...

And you can develop 32-bit (WinForms) .NET apps and run them on 64 bit
systems with MS Access or MS SQL backend - just use corflags.exe
(http://msdn.microsoft.com/en-us/library/ms164699(v=vs.80).aspx)

Thank you.

Hello All,

I saw a presentation on Lightswitch a few months ago.  I have to say I was
very impressed.  IMO, Lightswitch was giving tools to common people that
enabled them to build web apps as fast as we built database apps in the 90's
with Access.

The presenter used the concept of two types of users / developers, a big D
and a little d.  The little d is the guy in the small business, or in the IT
hardware dept and he needs an app for raising Cap Ex.  In lightswitch he can
code that in 1 hour and he can get back to his Server room.  For the big D,
there are also lots of powerful tools that mean he can use lightswitch for a
lot of a software project.

It really reminded me of the 90's when C++ existed and then we get Access
with VBA.

Thanks

Mark

The first look of Windows 8 may be a bit of a curiosity. 

Actually, it is two products in one or a core with two distros...like Linux,
given say, Lime and Ubuntu, each interface looks completely different but
each has the same kernel. There will be the new default browser/cell phone
type interface and then there will be Windows7. 

http://www.theregister.co.uk/2011/09/13/windows_8_preview/

I think this product is an evolutionary product...One part says desktop PC
and the other says Web based browser. The interface is just a step on the
journey which will lead away from the desktop PC to an internet support
application. 

Many articles have been written saying it more bluntly, but this is the
formal acceptance and official agreement, on the part of Microsoft. They
have just acknowledged the truth and that is that the PC, as we know it, is
dead.

So boys and girls if you plan to be working in the computer industry, of the
future get your internet skills ready. Learn about web servers, internet
protocols, distributive databases, HTMLx, CSSx, JavaScript, web based
graphics and cloud based applications (and all the forth-coming
generations). 

It is going to be a thrilling ride as we launch off from the PC.

Maybe in the US where internet access is fast and bandiwdth is cheap.   It will be many years 
before businesses in much of the world are prepared to go that way.

Subject: [dba-VB] MySQL
Message-ID: <4E752C1D.9060901@colbyconsulting.com>

Today I built a Windows XP SP3 VM (x32) and installed MySQL Community Edition.  I installed all the 
prereqs, the database and the ODBC connector.  The .Net connector refused to install due to missing 
.net 2.0 or 4.0.

I also installed the workbench.

It looks very foreign.  It is very foreign.  This is the part of new technology I hate, that first 
look - "I don't recognize a thing" feeling.

Being a vm, I have a boot drive and a data drive.  The boot is 30 gigs and the data is 60 gigs. 
Let's hope that is enough, though one would think so for small databases.

I am trying to learn enough to assist a client with evaluating MySQL for replacing his Access MDB 
data store.

For now I have to figure out how to create a database.  Is it the same concept as SQL Server?  A 
file or set of files where tables, indexes, views etc are stored?  I assumed there would be some 
visual designer that would allow me to create the db, then tables etc.  It looks like that stuff is 
in "SQL Development".

This thing looks pretty nice, but very different on the surface.

I run MySQL locally as part of a WAMP installation and remotely on our FreeBSD servers.

I use phpMyAdmin for all the administration.   It's a very intuitive interface.

It's possibly worth installing WAMP just for the phpMyAdmin.

Hi Shamil

No, I haven't got that far.

My first guess was that the table schemes of Northwind perhaps didn't correlate 100% with that expected by LightSwitch.

But the link you provided tells that a separate instance of SQL Server Express 2005/2008 (not any other version) is required to support LS itself during development to not mix up "development data" with your application data (user data). 

That I didn't know about, and it may cause trouble around where you use the development version of SQL Server 2008 for your local work.

Hi All --

To avoid issues with ProductDetails table I have just checked it out from
external datasource while generating new MS Lightswitch project - and I have
got infamous:

Hi Gustav at all --

I have got MS LightSwitch 2011 installed, and I have tried to create

Sorry for my English but what they mean in the last sensence by "finish it"?

If anybody here have any idea how to fix the above issue that would be very

Hi Gustav --

The issue was with table name [OrderDetail] and relationship name
OrderDetails collision - with  [OrderDetail] table getting OrderDetails
entities collection name (or something like that) when MS Lightswitch did
got generated EF data model - I have chenaged relationship name to
OrderItems - and voila' - the MS Lightswitch project compiles well now.

I have also got "hacked" the issue described here:

http://social.msdn.microsoft.com/Forums/en-US/lightswitchgeneral/thread/de2e
7ee5-fc82-4614-9245-4f4a9ae7185f

and I have now MS Lightswitch/Northwind tiny sample app with five
search/view/edit forms/secreens running locally under Visual Studio:

http://smsconsulting.spb.ru/test/s3.png

http://smsconsulting.spb.ru/test/s5.png

I will try to write more on that "hacking" in coming days if time will allow
and I will also try to publish this app...

Still don't understand why that MS SQL "__IntrinsicData" MS SQLExpress
instance can't be swicthed-off/"hacked" via MS Lightswitch development
interface/properties - hope it will be possible to do that in the coming MS
Lightswitch updates...

Thank you.

Hi Shamil

Great! I knew they couldn't fool you.

Beth Massi of MS tells why SQL Express is needed:

<quote>
SQL Express is necessary because at development time, LightSwitch uses a User Instance of the database (this automatically attaches the database "on-the-fly" to the SQL service. Only SQL Express supports this option. If we didn't do it this way then you would not be able to easily share LightSwitch solutions with other developers or "F5" samples.

Hope this makes more sense now.
</quote>

Perhaps it makes sense, but I still don't understand why only the Express edition can carry out this "magic" which sounds pretty simple.

Thanks for the screen shots. Looks promising.

Well, I have read that - it does make some sense but imagine a use case
when datamodel/backend database exists and powerusers and developers have to
work just on LightSwitch forms, workflows etc. - the LightSwitch project
items, which are not  kept stored in backend DB - in this case binding to
SQLExpress looks unneeded and limiting - am I wrong? (that my "ranting"

Thank you, unfortunately I have to postpone that sample project work for a
couple of months - real customers' projects got higher priority here and
OpenXML SDK 2.0 I have just posted about in Access-D.
And I should probably not publish MS LightSwitch "hacking" information at
all - we will see - hopefully MS will soon fix this SQLExpress bidning issue
in the new MS LightSwitch versions/upgrades...

Message-ID: <004b01cc7d29$c82e2420$588a6c60$@comcast.net>

I have unfortunately discovered that there is no built-in method to create a
spreadsheet from within VB.Net, similar to DoCmd.TransferSpreadsheet like
there is in Access.

I've tried three different methods, but all have failed for one reason or
another.  There are numerous 3rd party solutions, but right now I just need
to do the basic step of creating a csv or xls file.

I'm starting with a Linq query (an IEnumerable).  I'd like to use this as
the starting point, but I could convert that to a DataTable, or to a DataSet
if needed.

If anyone does this successfully, please let me know.

Thanks!
Dan

Honestly, programmers these days!  If there's no "built in method",  they're lost.  That's what 
.Net does for your :-)
 
Grab some data ( any data)
Open a file for Output
Step through your data, building a comma separated list for each record and write it to the a 
file.

If you want to write the data into an actual Excel file, use COM.  Again, step through your 
data writing values out to the file,  You could base it on something like
http://vb.net-informations.com/excel-2007/vb.net_excel_2007_create_file.htm

You can save a datatable as xml which Excel can open.

Honestly, programmers these days!  If there's no "built in method",  they're
lost.  That's what .Net does for your :-)
 
Grab some data ( any data)
Open a file for Output
Step through your data, building a comma separated list for each record and
write it to the a file.

If you want to write the data into an actual Excel file, use COM.  Again,
step through your data writing values out to the file,  You could base it on
something like

Message-ID: <DB7C1015741D45A48F326233AACC2606@nant>


Hi All --

Just wanted to share my experience in using .NET 4.0 Task Parallel Library
(TPL):

http://msdn.microsoft.com/en-us/library/dd460693.aspx

I have recently developed and released to a customer an advanced WinForms
project/application having running dozen of parallel tasks

- getting data from external data sources/web services and local lookup
databases, 
- coordinating data, 
- CRUD-ing results into MS SQL 2008 back-end and log file, 
- displaying progress on WinForm...

I have used .NET 4.0 C# and TPL - the following classes:

- System.Threading.Tasks.Task
- System.Collections.Concurrent.ConcurrentBag<T>
- System.Collections.Concurrent.ConcurrentDictionary<TKey, TValue>
- System.Threading.Barrier
- C# lock statement

and 

- System.ComponentModel.BackgroundWorker to activate and run the main thread
"talking to" WinForms UI via Invoke.

TPL and related data structures and classes help to significantly simplify
coordination of the parallel tasks execution, still programming of
coordinated parallel tasks' execution is rather advanced activity - plan
one-two weeks of "learning by doing" if/when you'll find you wanted to use
TPL in your projects...

Thank you.

Hi Gustav --

Thank you for your question - yes, the final result/experience is positive
- the application is now up&running 24x7x365 on customer's system - no
runtime errors, no memory leakage...

Although it took quite some efforts to make it working like that - be
prepared to spend one-two weeks of intensive development - just to learn and
master TPL development and catch and fix all kinds of "race conditions". It
happened I have had to write a tiny "framework" on top of TPL - that handles
initialization of TPL tasks, keeping and reporting status, logging, running
tasks asynchronously (main usage scenario) or synchronously (used for
testing) etc. This "framework" is not yet ready for sharing - maybe I will
share it "one fine day" if anybody proposes a composite sample task to be
split into, say dozen of subtasks to be run in parallel, which I can
implement using mentioned above tiny "framework" and publish for
reviewing...

BTW, I have started to read "Professional Test Driven Development with C#:
Developing Real World Applications with TDD"  by James Bender and Jeff
McWheter
(http://www.amazon.com/Professional-Test-Driven-Development-Applications/dp/
047064320X) and do agree with review you can find on Amazon - "It is one of
the best development books I have ever read and I highly recommend it" (I
personally do try to follow TDD approach for almost five years now - and it
works well for me amd my customers' projects (strict deadlines, "bad coding
habits", inertia etc. do disturb me to follow TDD "fanatically") but I have
never seen such a good, concise and practical book for .NET C# TDD
development - I second almost every word of it - I wish I had written one
like that :))

Thank you.

It has, and has even been labeled Go Live. I guess it means some kind of improved level of support.

That took me a couple of minutes - and another couple to copy and paste the links and post these here.
Then I browsed the development pages a little and people and the team seem quite active.

Subject: [dba-VB] SQL Server compression
Message-ID: <4E650719.7020301@colbyconsulting.com>

The other day I populated the second socket of my (AMD) server with another 8 core chip.  With cores 
to spare I decided to give compression a whirl.  I am finding a lot of stuff out there now saying 
that it reduces the I/O a ton and that if you are not cpu limited then it makes the database faster 
because more stuff fits into memory.  Basically the objective is to get as much of the stuff that is 
being actively used to stay resident in memory.

One immediate benefit is that it cuts the total size of my databases on disk roughly in half.  This 
is a good thing because I keep the major players on SSD which is expensive.  Keeping them compressed 
means that I have more room on the SSD.

When I got into this business in October 2004 I had servers with AMD single core 3.8 ghz and 4 gigs 
or RAM running x32 windows and sql server.  I was trying to run count queries on 100 gb databases 
and while it worked, it was... not fast. I would run counts that took a half hour.

Through knowledge acquired on these lists I rebuilt my database tables, learned indexing, and made 
the databases much more efficient.

Seven years later I have 16 cores and 32 gigs RAM running X64 windows and SQL server.  A year ago I 
bought 32 gigs of DDR3 1300 registered ECC ram for $1000.  Today I ordered another 32 gigs for $400.

It is incredible to me that using brute force and ignorance, I can now keep multiple largish 
databases entirely in memory.  While I have no benchmarks recorded to compare yesteryear to today, I 
am doing things in minutes or even seconds that would have taken me a half hour or even hours seven 
years ago.

These are exciting times.

BTW I found something called GeekBench which I ran on my machine.  It is the only thing I have found 
that is a reasonable cost ($13) to give me numbers to compare to others.  My Geekbench number is 
~13,500, and it pointed out to me that I am currently running the server with 1/2 of the memory 
"bandwidth" I could be getting (the biggest reason I am adding more).

I had 4 DIMMS and a single processor.  The processor has a 4 port memory controller.  When I added 
the new processor I redistributed the memory so that each chip had 1/2 of the memory (2 dimms) but 
in doing so I "crippled" the memory controller.  The price of memory is dropping like a rock so now 
seems like a good time to top up.  It will be interesting to see what filling out the memory 
controller does to the numbers.

I "retired" my previous server to be my VM server, and it just occurred to me that I can run 
Geekbench on that to get a comparison of my previous server against my current server.  My previous 
server is an AMD quad core with 16 gigs of RAM and the geekbench on that is 7469.

Hi Shamil

No one knows, and so many smart opinions out there about what is "dead" or "hot". 
MS claims that Silverlight will remain a focus product but who knows?

Neither Silverlight, LightSwitch, or Access for that matter, is the answer for everything, but I find LightSwitch to be much of that Access should have been.

Most smartphone users will have an Android. I have a Windows Phone 7 and find it superior.

Hi Gustav --

Yes, no one knows what technology will "fire" in the near future
I just noted I feel a bit "tired of custom MS technologies" - trying to make
money here using a limited (but huge - .NET framework IS huge) set of MS
technologies and to use as much as possible generally accepted software
development technologies, practices and standards...

BTW, I do plan to purchase Windows Phone 7/8 - if MS LightSwitch will be
able (isn't it yet?) to prototype/develop Windows Phone 7/8 apps I would
definitely try to use it...

Thank you.

Hi Shamil

No one knows, and so many smart opinions out there about what is "dead" or
"hot". 
MS claims that Silverlight will remain a focus product but who knows?

Neither Silverlight, LightSwitch, or Access for that matter, is the answer
for everything, but I find LightSwitch to be much of that Access should have
been.

Most smartphone users will have an Android. I have a Windows Phone 7 and
find it superior.

Hi Gustav --

Thank you for your information.

I personally do not plan to work (and even to play) with MS LightSwitch.
I can be wrong - but as far as I have heard/read HTML5/CSS3/JavaScript will
soon (in a few years?) make Adobe Flash and SilverLight(?) a kind of
"obsolete" technologies:

http://ntt.cc/2010/03/15/will-html5-css-javascript-really-be-flash-and-silve
rlight-killer.html

and iPad doesn't support Adobe Flash (does it support Silverlight?) - and
according to the referred above article everybody will soon have an iPad :)

Thank you.

Hi Shamil

For a small project I recalled LightSwitch and wondered if it had moved
anywhere.
It has, and has even been labeled Go Live. I guess it means some kind of
improved level of support.

That took me a couple of minutes - and another couple to copy and paste the
links and post these here.
Then I browsed the development pages a little and people and the team seem
quite active.

But I still miss the time for testing ...

Hi Doug,

Thank you - this is why I'm "talking HTML5/CSS3/JavaScript" here - iPad is
rather popular here because of the current Russian president using it.
I do "wild guess" Windows Phone 7/8 will be also popular here when its
localized version will be released still I have to take into account Android
and iPhone users when developing mobile apps...

Hi Shamil

The goal for LightSwitch is RAD of Silverlight Line Of Business apps for simultaneous deployment as desktop and browser application as you prefer. It is not (yet) for phone development as far as I know.

For Windows Phone development you currently use the development kit for Visual Studio 2010 and the associated Phone simulator.

The Gadgeteer looks cool but expensive. And a little more mechanics is needed if you ask me - to make the Meccano of our time.

3D printing I saw in real life at an exhibition several years ago and was amazed. It was used to create prototypes of items for later plastic molding. Items were relatively "coarse" at that time, but I'm convinced that this technique will turn many things upside down. Just think of how laser printing replaced offset print in many areas and how video projectors have killed old days' slide projector - and currently movie projection in cinemas.

The key parameter of 3D printing is, of course, the strength of the produced items. This evolves rapidly. At one point, think how you could bring a 3D printer and a bunch of printing powder to Mars, then you can produce any item locally. The list goes on.

Hi Gustav --

Yes, no one knows what technology will "fire" in the near future
I just noted I feel a bit "tired of custom MS technologies" - trying to make
money here using a limited (but huge - .NET framework IS huge) set of MS
technologies and to use as much as possible generally accepted software
development technologies, practices and standards...

BTW, I do plan to purchase Windows Phone 7/8 - if MS LightSwitch will be
able (isn't it yet?) to prototype/develop Windows Phone 7/8 apps I would
definitely try to use it...

Thank you.

P.S. ".NET Gadgeteer" and "3D printing" look very cool from here - imagine
one will be able to design and to "3d print" "home hand made" custom gadgets
in a few years:

"Gadgeteer utilizes the .NET Micro Framework to make writing code for your
device *as easy as* writing a desktop, Web or Windows Phone application."

Hi John

Not currently, but we do have a client with a heavily customized Access 97 application which we delivered summer 1999 and have expanded in steps through the years. This is for an organisation of dealers of agricultural machinery (combined harvesters, etc.) and as you can imagine, age is showing. It's not a question of reliability as the app has ran with zero errors or breakdowns. But new desktops we run with Windows 7 32-bit to avoid trouble with A97 and 64-bit OS, web interface is missing, etc. 

The office is only five people so budget is if not tight then limited and, as the app (three frontends actually with two backends for data and pictures) runs the full business, a replacement must be efficient and predictable to develop. However, the app contains nothing fancy - it's really a typical Line Of Business app taking care of everything a small organisation needs - exactly what LightSwitch is for.

So my plan is to model an introductory LS app to demonstrate how a single task could be performed and see if the client likes it. Then move on with a SQL Server 2008 backend (already running on their SBS).

If you should ask, we have no intention to move the app to Access 2010. I regard Access as a dead end for developers and the lack of a web interface other than SharePoint is a show-stopper.

Hi Shamil

I did consider that but funding will never be fat. The organisation counts only a few hundred members, and as the backends are only 150 MB I will face no scaling issue. It is exactly what LS is targeted for, so for this reason alone I will do the test. It may, of course, prove unsatisfactory in some way and if so I  will for sure choose the WinForms route which works very well for me.

We have one client where I have used the click-once deployment method and it works very well. Even the smallest modification, which I can code in minutes, gets deployed at once as it just requires a few default clicks and a password to the clients local FTP server and it has been published. It can't be easier and it just works.

Hello All,

I saw a presentation on Lightswitch a few months ago.  I have to say I was
very impressed.  IMO, Lightswitch was giving tools to common people that
enabled them to build web apps as fast as we built database apps in the 90's
with Access.

The presenter used the concept of two types of users / developers, a big D
and a little d.  The little d is the guy in the small business, or in the IT
hardware dept and he needs an app for raising Cap Ex.  In lightswitch he can
code that in 1 hour and he can get back to his Server room.  For the big D,
there are also lots of powerful tools that mean he can use lightswitch for a
lot of a software project.

It really reminded me of the 90's when C++ existed and then we get Access
with VBA.

Thanks

Mark

The first look of Windows 8 may be a bit of a curiosity. 

Actually, it is two products in one or a core with two distros...like Linux,
given say, Lime and Ubuntu, each interface looks completely different but
each has the same kernel. There will be the new default browser/cell phone
type interface and then there will be Windows7. 

http://www.theregister.co.uk/2011/09/13/windows_8_preview/

I think this product is an evolutionary product...One part says desktop PC
and the other says Web based browser. The interface is just a step on the
journey which will lead away from the desktop PC to an internet support
application. 

Many articles have been written saying it more bluntly, but this is the
formal acceptance and official agreement, on the part of Microsoft. They
have just acknowledged the truth and that is that the PC, as we know it, is
dead.

So boys and girls if you plan to be working in the computer industry, of the
future get your internet skills ready. Learn about web servers, internet
protocols, distributive databases, HTMLx, CSSx, JavaScript, web based
graphics and cloud based applications (and all the forth-coming
generations). 

It is going to be a thrilling ride as we launch off from the PC.

Maybe in the US where internet access is fast and bandiwdth is cheap.   It will be many years 
before businesses in much of the world are prepared to go that way.

Subject: [dba-VB] MySQL
Message-ID: <4E752C1D.9060901@colbyconsulting.com>

Today I built a Windows XP SP3 VM (x32) and installed MySQL Community Edition.  I installed all the 
prereqs, the database and the ODBC connector.  The .Net connector refused to install due to missing 
.net 2.0 or 4.0.

I also installed the workbench.

It looks very foreign.  It is very foreign.  This is the part of new technology I hate, that first 
look - "I don't recognize a thing" feeling.

Being a vm, I have a boot drive and a data drive.  The boot is 30 gigs and the data is 60 gigs. 
Let's hope that is enough, though one would think so for small databases.

I am trying to learn enough to assist a client with evaluating MySQL for replacing his Access MDB 
data store.

For now I have to figure out how to create a database.  Is it the same concept as SQL Server?  A 
file or set of files where tables, indexes, views etc are stored?  I assumed there would be some 
visual designer that would allow me to create the db, then tables etc.  It looks like that stuff is 
in "SQL Development".

This thing looks pretty nice, but very different on the surface.

I run MySQL locally as part of a WAMP installation and remotely on our FreeBSD servers.

I use phpMyAdmin for all the administration.   It's a very intuitive interface.

It's possibly worth installing WAMP just for the phpMyAdmin.

When I have got removed one non-unique indexes from ProductDetails table
supposing that it was the cause of the above errors I have got VS going
down/restarting and presenting me a message:

+++
There are critical errors in the application definition metadata.
These errors must be fixed before the project can be loaded in the designer.
Check the errors in the errors window, and fix them in the text editor.
When you finish it, please use the "Reload" button to reload it into the
designer.
----

Sorry for my English but what they mean in the last sensence by "finish it"?
- I got it as to finish ASAP my first Lightswitch "fighting session", and so
I finsihed it :)

If anybody here have any idea how to fix the above issue that would be very
helpful here.

Thank you.

Stuart,

I downloaded and installed Wamp and downloaded phpMyAdmin but am stuck there.  It is just a bunch of 
files, no install to run.

Hi Shamil

No, I haven't got that far.

My first guess was that the table schemes of Northwind perhaps didn't correlate 100% with that expected by LightSwitch.

But the link you provided tells that a separate instance of SQL Server Express 2005/2008 (not any other version) is required to support LS itself during development to not mix up "development data" with your application data (user data). 

That I didn't know about, and it may cause trouble around where you use the development version of SQL Server 2008 for your local work.

Hi Gustav --

The issue was with table name [OrderDetail] and relationship name
OrderDetails collision - with  [OrderDetail] table getting OrderDetails
entities collection name (or something like that) when MS Lightswitch did
got generated EF data model - I have chenaged relationship name to
OrderItems - and voila' - the MS Lightswitch project compiles well now.

I have also got "hacked" the issue described here:

http://social.msdn.microsoft.com/Forums/en-US/lightswitchgeneral/thread/de2e
7ee5-fc82-4614-9245-4f4a9ae7185f

and I have now MS Lightswitch/Northwind tiny sample app with five
search/view/edit forms/secreens running locally under Visual Studio:

http://smsconsulting.spb.ru/test/s3.png
http://smsconsulting.spb.ru/test/s4.png
http://smsconsulting.spb.ru/test/s5.png

I will try to write more on that "hacking" in coming days if time will allow
and I will also try to publish this app...

Still don't understand why that MS SQL "__IntrinsicData" MS SQLExpress
instance can't be swicthed-off/"hacked" via MS Lightswitch development
interface/properties - hope it will be possible to do that in the coming MS
Lightswitch updates...

Thank you.

Hi Shamil

Great! I knew they couldn't fool you.

Beth Massi of MS tells why SQL Express is needed:

<quote>
SQL Express is necessary because at development time, LightSwitch uses a User Instance of the database (this automatically attaches the database "on-the-fly" to the SQL service. Only SQL Express supports this option. If we didn't do it this way then you would not be able to easily share LightSwitch solutions with other developers or "F5" samples.

Hope this makes more sense now.
</quote>

Perhaps it makes sense, but I still don't understand why only the Express edition can carry out this "magic" which sounds pretty simple.

Thanks for the screen shots. Looks promising.

Well, I have read that - it does make some sense but imagine a use case
when datamodel/backend database exists and powerusers and developers have to
work just on LightSwitch forms, workflows etc. - the LightSwitch project
items, which are not  kept stored in backend DB - in this case binding to
SQLExpress looks unneeded and limiting - am I wrong? (that my "ranting"

Thank you, unfortunately I have to postpone that sample project work for a
couple of months - real customers' projects got higher priority here and
OpenXML SDK 2.0 I have just posted about in Access-D.
And I should probably not publish MS LightSwitch "hacking" information at
all - we will see - hopefully MS will soon fix this SQLExpress bidning issue
in the new MS LightSwitch versions/upgrades...

http://social.msdn.microsoft.com/Forums/en-US/lightswitchgeneral/thread/de2e
7ee5-fc82-4614-9245-4f4a9ae7185f

and I have now MS Lightswitch/Northwind tiny sample app with five
search/view/edit forms/secreens running locally under Visual Studio:

http://smsconsulting.spb.ru/test/s3.png
http://smsconsulting.spb.ru/test/s4.png
http://smsconsulting.spb.ru/test/s5.png 

I will try to write more on that "hacking" in coming days if time will allow
and I will also try to publish this app...

Still don't understand why that MS SQL "__IntrinsicData" MS SQLExpress
instance can't be swicthed-off/"hacked" via MS Lightswitch development
interface/properties - hope it will be possible to do that in the coming MS
Lightswitch updates...

Thank you.

Subject: [dba-VB] Exporting Data to an Excel Spreadsheet
Message-ID: <004b01cc7d29$c82e2420$588a6c60$@comcast.net>

I have unfortunately discovered that there is no built-in method to create a
spreadsheet from within VB.Net, similar to DoCmd.TransferSpreadsheet like
there is in Access.

I've tried three different methods, but all have failed for one reason or
another.  There are numerous 3rd party solutions, but right now I just need
to do the basic step of creating a csv or xls file.

I'm starting with a Linq query (an IEnumerable).  I'd like to use this as
the starting point, but I could convert that to a DataTable, or to a DataSet
if needed.

If anyone does this successfully, please let me know.

Thanks!
Dan

Honestly, programmers these days!  If there's no "built in method",  they're lost.  That's what 
.Net does for your :-)
 
Grab some data ( any data)
Open a file for Output
Step through your data, building a comma separated list for each record and write it to the a 
file.

If you want to write the data into an actual Excel file, use COM.  Again, step through your 
data writing values out to the file,  You could base it on something like

Message-ID: <DB7C1015741D45A48F326233AACC2606@nant>


Hi All --

Just wanted to share my experience in using .NET 4.0 Task Parallel Library
(TPL):

http://msdn.microsoft.com/en-us/library/dd460693.aspx

I have recently developed and released to a customer an advanced WinForms
project/application having running dozen of parallel tasks

- getting data from external data sources/web services and local lookup
databases, 
- coordinating data, 
- CRUD-ing results into MS SQL 2008 back-end and log file, 
- displaying progress on WinForm...

I have used .NET 4.0 C# and TPL - the following classes:

- System.Threading.Tasks.Task
- System.Collections.Concurrent.ConcurrentBag<T>
- System.Collections.Concurrent.ConcurrentDictionary<TKey, TValue>
- System.Threading.Barrier
- C# lock statement

and 

- System.ComponentModel.BackgroundWorker to activate and run the main thread
"talking to" WinForms UI via Invoke.

TPL and related data structures and classes help to significantly simplify
coordination of the parallel tasks execution, still programming of
coordinated parallel tasks' execution is rather advanced activity - plan
one-two weeks of "learning by doing" if/when you'll find you wanted to use
TPL in your projects...

Thank you.

Hi Gustav --

Thank you for your question - yes, the final result/experience is positive
- the application is now up&running 24x7x365 on customer's system - no
runtime errors, no memory leakage...

Although it took quite some efforts to make it working like that - be
prepared to spend one-two weeks of intensive development - just to learn and
master TPL development and catch and fix all kinds of "race conditions". It
happened I have had to write a tiny "framework" on top of TPL - that handles
initialization of TPL tasks, keeping and reporting status, logging, running
tasks asynchronously (main usage scenario) or synchronously (used for
testing) etc. This "framework" is not yet ready for sharing - maybe I will
share it "one fine day" if anybody proposes a composite sample task to be
split into, say dozen of subtasks to be run in parallel, which I can
implement using mentioned above tiny "framework" and publish for
reviewing...

BTW, I have started to read "Professional Test Driven Development with C#:
Developing Real World Applications with TDD"  by James Bender and Jeff
McWheter
(http://www.amazon.com/Professional-Test-Driven-Development-Applications/dp/
047064320X) and do agree with review you can find on Amazon - "It is one of
the best development books I have ever read and I highly recommend it" (I
personally do try to follow TDD approach for almost five years now - and it
works well for me amd my customers' projects (strict deadlines, "bad coding
habits", inertia etc. do disturb me to follow TDD "fanatically") but I have
never seen such a good, concise and practical book for .NET C# TDD
development - I second almost every word of it - I wish I had written one
like that :))

Thank you.

It has, and has even been labeled Go Live. I guess it means some kind of improved level of support.

Then I browsed the development pages a little and people and the team seem quite active.

Subject: [dba-VB] SQL Server compression
Message-ID: <4E650719.7020301@colbyconsulting.com>

The other day I populated the second socket of my (AMD) server with another 8 core chip.  With cores 
to spare I decided to give compression a whirl.  I am finding a lot of stuff out there now saying 
that it reduces the I/O a ton and that if you are not cpu limited then it makes the database faster 
because more stuff fits into memory.  Basically the objective is to get as much of the stuff that is 
being actively used to stay resident in memory.

One immediate benefit is that it cuts the total size of my databases on disk roughly in half.  This 
is a good thing because I keep the major players on SSD which is expensive.  Keeping them compressed 
means that I have more room on the SSD.

When I got into this business in October 2004 I had servers with AMD single core 3.8 ghz and 4 gigs 
or RAM running x32 windows and sql server.  I was trying to run count queries on 100 gb databases 
and while it worked, it was... not fast. I would run counts that took a half hour.

Through knowledge acquired on these lists I rebuilt my database tables, learned indexing, and made 
the databases much more efficient.

Seven years later I have 16 cores and 32 gigs RAM running X64 windows and SQL server.  A year ago I 
bought 32 gigs of DDR3 1300 registered ECC ram for $1000.  Today I ordered another 32 gigs for $400.

It is incredible to me that using brute force and ignorance, I can now keep multiple largish 
databases entirely in memory.  While I have no benchmarks recorded to compare yesteryear to today, I 
am doing things in minutes or even seconds that would have taken me a half hour or even hours seven 
years ago.

These are exciting times.

BTW I found something called GeekBench which I ran on my machine.  It is the only thing I have found 
that is a reasonable cost ($13) to give me numbers to compare to others.  My Geekbench number is 
~13,500, and it pointed out to me that I am currently running the server with 1/2 of the memory 
"bandwidth" I could be getting (the biggest reason I am adding more).

I had 4 DIMMS and a single processor.  The processor has a 4 port memory controller.  When I added 
the new processor I redistributed the memory so that each chip had 1/2 of the memory (2 dimms) but 
in doing so I "crippled" the memory controller.  The price of memory is dropping like a rock so now 
seems like a good time to top up.  It will be interesting to see what filling out the memory 
controller does to the numbers.

I "retired" my previous server to be my VM server, and it just occurred to me that I can run 
Geekbench on that to get a comparison of my previous server against my current server.  My previous 
server is an AMD quad core with 16 gigs of RAM and the geekbench on that is 7469.

Hi Gustav --

Thank you for your information.

I personally do not plan to work (and even to play) with MS LightSwitch.
I can be wrong - but as far as I have heard/read HTML5/CSS3/JavaScript will
soon (in a few years?) make Adobe Flash and SilverLight(?) a kind of
"obsolete" technologies:

http://ntt.cc/2010/03/15/will-html5-css-javascript-really-be-flash-and-silve
rlight-killer.html

and iPad doesn't support Adobe Flash (does it support Silverlight?) - and
according to the referred above article everybody will soon have an iPad :)

Thank you.

Hi Shamil

No one knows, and so many smart opinions out there about what is "dead" or "hot". 
MS claims that Silverlight will remain a focus product but who knows?

Neither Silverlight, LightSwitch, or Access for that matter, is the answer for everything, but I find LightSwitch to be much of that Access should have been.

Most smartphone users will have an Android. I have a Windows Phone 7 and find it superior.

I can be wrong - but as far as I have heard/read HTML5/CSS3/JavaScript will
soon (in a few years?) make Adobe Flash and SilverLight(?) a kind of
"obsolete" technologies:

No:

Hi Shamil

For a small project I recalled LightSwitch and wondered if it had moved anywhere.
It has, and has even been labeled Go Live. I guess it means some kind of improved level of support.

That took me a couple of minutes - and another couple to copy and paste the links and post these here.
Then I browsed the development pages a little and people and the team seem quite active.

But I still miss the time for testing ...

Hi Gustav --

Yes, no one knows what technology will "fire" in the near future
I just noted I feel a bit "tired of custom MS technologies" - trying to make
money here using a limited (but huge - .NET framework IS huge) set of MS
technologies and to use as much as possible generally accepted software
development technologies, practices and standards...

BTW, I do plan to purchase Windows Phone 7/8 - if MS LightSwitch will be
able (isn't it yet?) to prototype/develop Windows Phone 7/8 apps I would
definitely try to use it...

Thank you.

Hi Shamil

No one knows, and so many smart opinions out there about what is "dead" or
"hot". 
MS claims that Silverlight will remain a focus product but who knows?

Neither Silverlight, LightSwitch, or Access for that matter, is the answer
for everything, but I find LightSwitch to be much of that Access should have
been.

Most smartphone users will have an Android. I have a Windows Phone 7 and
find it superior.

The iPad doesn't support Silverlight any more than the iPhone does.  When
you arrive at a Silverlight web page, you get a message asking you to
install Silverlight, which of course you can't.

Hi Doug,

Thank you - this is why I'm "talking HTML5/CSS3/JavaScript" here - iPad is
rather popular here because of the current Russian president using it.
I do "wild guess" Windows Phone 7/8 will be also popular here when its
localized version will be released still I have to take into account Android
and iPhone users when developing mobile apps...

Hi Shamil

The goal for LightSwitch is RAD of Silverlight Line Of Business apps for simultaneous deployment as desktop and browser application as you prefer. It is not (yet) for phone development as far as I know.

For Windows Phone development you currently use the development kit for Visual Studio 2010 and the associated Phone simulator.

The Gadgeteer looks cool but expensive. And a little more mechanics is needed if you ask me - to make the Meccano of our time.

3D printing I saw in real life at an exhibition several years ago and was amazed. It was used to create prototypes of items for later plastic molding. Items were relatively "coarse" at that time, but I'm convinced that this technique will turn many things upside down. Just think of how laser printing replaced offset print in many areas and how video projectors have killed old days' slide projector - and currently movie projection in cinemas.

The key parameter of 3D printing is, of course, the strength of the produced items. This evolves rapidly. At one point, think how you could bring a 3D printer and a bunch of printing powder to Mars, then you can produce any item locally. The list goes on.

Then I browsed the development pages a little and people and the team seem
quite active.

But I still miss the time for testing ...

Hi Gustav --

How do you manage to find free time to watch for and to even try(?!) Beta
releases of MS software?
I can't find that free time...

Thank you.

Hi all

Here is a better, though still brief, introduction to the new beta:

http://social.msdn.microsoft.com/Forums/en-US/lightswitchgeneral/threads
Click at the top under Announcements the topic:
Visual Studio LightSwitch Beta 2 Released with Go Live License!

<quote>
.. We'd also like to announce that Beta 2 comes with a "Go Live" license
which means you can now start using Visual Studio LightSwitch for production
projects </quote>

Hi members of "VS2010 SP1 club"

Then those interested in true RAD may proceed obtaining the recent
LightSwitch Beta 2 which requires VS2010 SP1:
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=cff6c4ef-a29a-4c
82-9a59-8a3bbb65ec3d 

The Beta 1 must be uninstalled first.
Apart from many minor improvements "too numerous to mention" as the team
tells, an interesting new feature is direct deployment to Windows/SQL Azure.

Also, the Visual Studio LightSwitch Beta 2 Training Kit:

That is another big reason to avoid proprietary software, as you never know
who your next client will be and open standard software will always be
there.

Hi Shamil

The iPad doesn't support Silverlight any more than the iPhone does.  When
you arrive at a Silverlight web page, you get a message asking you to
install Silverlight, which of course you can't.

Hi John

Not currently, but we do have a client with a heavily customized Access 97 application which we delivered summer 1999 and have expanded in steps through the years. This is for an organisation of dealers of agricultural machinery (combined harvesters, etc.) and as you can imagine, age is showing. It's not a question of reliability as the app has ran with zero errors or breakdowns. But new desktops we run with Windows 7 32-bit to avoid trouble with A97 and 64-bit OS, web interface is missing, etc. 

The office is only five people so budget is if not tight then limited and, as the app (three frontends actually with two backends for data and pictures) runs the full business, a replacement must be efficient and predictable to develop. However, the app contains nothing fancy - it's really a typical Line Of Business app taking care of everything a small organisation needs - exactly what LightSwitch is for.

So my plan is to model an introductory LS app to demonstrate how a single task could be performed and see if the client likes it. Then move on with a SQL Server 2008 backend (already running on their SBS).

If you should ask, we have no intention to move the app to Access 2010. I regard Access as a dead end for developers and the lack of a web interface other than SharePoint is a show-stopper.

Hi Shamil

I did consider that but funding will never be fat. The organisation counts only a few hundred members, and as the backends are only 150 MB I will face no scaling issue. It is exactly what LS is targeted for, so for this reason alone I will do the test. It may, of course, prove unsatisfactory in some way and if so I  will for sure choose the WinForms route which works very well for me.

We have one client where I have used the click-once deployment method and it works very well. Even the smallest modification, which I can code in minutes, gets deployed at once as it just requires a few default clicks and a password to the clients local FTP server and it has been published. It can't be easier and it just works.

Hello All,

I saw a presentation on Lightswitch a few months ago.  I have to say I was
very impressed.  IMO, Lightswitch was giving tools to common people that
enabled them to build web apps as fast as we built database apps in the 90's
with Access.

The presenter used the concept of two types of users / developers, a big D
and a little d.  The little d is the guy in the small business, or in the IT
hardware dept and he needs an app for raising Cap Ex.  In lightswitch he can
code that in 1 hour and he can get back to his Server room.  For the big D,
there are also lots of powerful tools that mean he can use lightswitch for a
lot of a software project.

It really reminded me of the 90's when C++ existed and then we get Access
with VBA.

Thanks

Mark

The first look of Windows 8 may be a bit of a curiosity. 

Actually, it is two products in one or a core with two distros...like Linux,
given say, Lime and Ubuntu, each interface looks completely different but
each has the same kernel. There will be the new default browser/cell phone
type interface and then there will be Windows7. 

http://www.theregister.co.uk/2011/09/13/windows_8_preview/

I think this product is an evolutionary product...One part says desktop PC
and the other says Web based browser. The interface is just a step on the
journey which will lead away from the desktop PC to an internet support
application. 

Many articles have been written saying it more bluntly, but this is the
formal acceptance and official agreement, on the part of Microsoft. They
have just acknowledged the truth and that is that the PC, as we know it, is
dead.

So boys and girls if you plan to be working in the computer industry, of the
future get your internet skills ready. Learn about web servers, internet
protocols, distributive databases, HTMLx, CSSx, JavaScript, web based
graphics and cloud based applications (and all the forth-coming
generations). 

It is going to be a thrilling ride as we launch off from the PC.

Maybe in the US where internet access is fast and bandiwdth is cheap.   It will be many years

Message-ID: <4E752C1D.9060901@colbyconsulting.com>

Today I built a Windows XP SP3 VM (x32) and installed MySQL Community Edition.  I installed all the 
prereqs, the database and the ODBC connector.  The .Net connector refused to install due to missing 
.net 2.0 or 4.0.

I also installed the workbench.

It looks very foreign.  It is very foreign.  This is the part of new technology I hate, that first 
look - "I don't recognize a thing" feeling.

Being a vm, I have a boot drive and a data drive.  The boot is 30 gigs and the data is 60 gigs. 
Let's hope that is enough, though one would think so for small databases.

I am trying to learn enough to assist a client with evaluating MySQL for replacing his Access MDB 
data store.

For now I have to figure out how to create a database.  Is it the same concept as SQL Server?  A 
file or set of files where tables, indexes, views etc are stored?  I assumed there would be some 
visual designer that would allow me to create the db, then tables etc.  It looks like that stuff is 
in "SQL Development".

This thing looks pretty nice, but very different on the surface.

I run MySQL locally as part of a WAMP installation and remotely on our FreeBSD servers.

I use phpMyAdmin for all the administration.   It's a very intuitive interface.

It's possibly worth installing WAMP just for the phpMyAdmin.

Hi Shamil

I did consider that but funding will never be fat. The organisation counts
only a few hundred members, and as the backends are only 150 MB I will face
no scaling issue. It is exactly what LS is targeted for, so for this reason
alone I will do the test. It may, of course, prove unsatisfactory in some
way and if so I  will for sure choose the WinForms route which works very
well for me.

We have one client where I have used the click-once deployment method and it
works very well. Even the smallest modification, which I can code in
minutes, gets deployed at once as it just requires a few default clicks and
a password to the clients local FTP server and it has been published. It
can't be easier and it just works.

Hi Shamil

No, I haven't got that far.

My first guess was that the table schemes of Northwind perhaps didn't correlate 100% with that expected by LightSwitch.

But the link you provided tells that a separate instance of SQL Server Express 2005/2008 (not any other version) is required to support LS itself during development to not mix up "development data" with your application data (user data). 

That I didn't know about, and it may cause trouble around where you use the development version of SQL Server 2008 for your local work.

Hi Gustav --

The issue was with table name [OrderDetail] and relationship name
OrderDetails collision - with  [OrderDetail] table getting OrderDetails
entities collection name (or something like that) when MS Lightswitch did
got generated EF data model - I have chenaged relationship name to
OrderItems - and voila' - the MS Lightswitch project compiles well now.

I have also got "hacked" the issue described here:

http://social.msdn.microsoft.com/Forums/en-US/lightswitchgeneral/thread/de2e
7ee5-fc82-4614-9245-4f4a9ae7185f

http://smsconsulting.spb.ru/test/s3.png

http://smsconsulting.spb.ru/test/s5.png

I will try to write more on that "hacking" in coming days if time will allow
and I will also try to publish this app...

Still don't understand why that MS SQL "__IntrinsicData" MS SQLExpress
instance can't be swicthed-off/"hacked" via MS Lightswitch development
interface/properties - hope it will be possible to do that in the coming MS
Lightswitch updates...

Thank you.

Hi Shamil

Great! I knew they couldn't fool you.

Beth Massi of MS tells why SQL Express is needed:

<quote>
SQL Express is necessary because at development time, LightSwitch uses a User Instance of the database (this automatically attaches the database "on-the-fly" to the SQL service. Only SQL Express supports this option. If we didn't do it this way then you would not be able to easily share LightSwitch solutions with other developers or "F5" samples.

Hope this makes more sense now.
</quote>

Perhaps it makes sense, but I still don't understand why only the Express edition can carry out this "magic" which sounds pretty simple.

Thanks for the screen shots. Looks promising.

Well, I have read that - it does make some sense but imagine a use case
when datamodel/backend database exists and powerusers and developers have to
work just on LightSwitch forms, workflows etc. - the LightSwitch project
items, which are not  kept stored in backend DB - in this case binding to
SQLExpress looks unneeded and limiting - am I wrong? (that my "ranting"

Yes, I don't understand that also.

Thank you, unfortunately I have to postpone that sample project work for a
couple of months - real customers' projects got higher priority here and
OpenXML SDK 2.0 I have just posted about in Access-D.
And I should probably not publish MS LightSwitch "hacking" information at
all - we will see - hopefully MS will soon fix this SQLExpress bidning issue
in the new MS LightSwitch versions/upgrades...

Thank you.

Hi Shamil

Great! I knew they couldn't fool you.

Beth Massi of MS tells why SQL Express is needed:

<quote>
SQL Express is necessary because at development time, LightSwitch uses a
User Instance of the database (this automatically attaches the database
"on-the-fly" to the SQL service. Only SQL Express supports this option. If
we didn't do it this way then you would not be able to easily share
LightSwitch solutions with other developers or "F5" samples.

Hope this makes more sense now.

Perhaps it makes sense, but I still don't understand why only the Express
edition can carry out this "magic" which sounds pretty simple.

Message-ID: <004b01cc7d29$c82e2420$588a6c60$@comcast.net>

I have unfortunately discovered that there is no built-in method to create a
spreadsheet from within VB.Net, similar to DoCmd.TransferSpreadsheet like
there is in Access.

I've tried three different methods, but all have failed for one reason or
another.  There are numerous 3rd party solutions, but right now I just need
to do the basic step of creating a csv or xls file.

I'm starting with a Linq query (an IEnumerable).  I'd like to use this as
the starting point, but I could convert that to a DataTable, or to a DataSet
if needed.

If anyone does this successfully, please let me know.

Thanks!
Dan

Honestly, programmers these days!  If there's no "built in method",  they're lost.  That's what 
.Net does for your :-)
 
Grab some data ( any data)
Open a file for Output
Step through your data, building a comma separated list for each record and write it to the a 
file.

If you want to write the data into an actual Excel file, use COM.  Again, step through your 
data writing values out to the file,  You could base it on something like

Message-ID: <DB7C1015741D45A48F326233AACC2606@nant>


Hi All --

Just wanted to share my experience in using .NET 4.0 Task Parallel Library
(TPL):

http://msdn.microsoft.com/en-us/library/dd460693.aspx

I have recently developed and released to a customer an advanced WinForms
project/application having running dozen of parallel tasks

- getting data from external data sources/web services and local lookup
databases, 
- coordinating data, 
- CRUD-ing results into MS SQL 2008 back-end and log file, 
- displaying progress on WinForm...

I have used .NET 4.0 C# and TPL - the following classes:

- System.Threading.Tasks.Task
- System.Collections.Concurrent.ConcurrentBag<T>
- System.Collections.Concurrent.ConcurrentDictionary<TKey, TValue>
- System.Threading.Barrier
- C# lock statement

and 

- System.ComponentModel.BackgroundWorker to activate and run the main thread
"talking to" WinForms UI via Invoke.

TPL and related data structures and classes help to significantly simplify
coordination of the parallel tasks execution, still programming of
coordinated parallel tasks' execution is rather advanced activity - plan
one-two weeks of "learning by doing" if/when you'll find you wanted to use
TPL in your projects...

Thank you.

Hi Gustav --

Thank you for your question - yes, the final result/experience is positive
- the application is now up&running 24x7x365 on customer's system - no
runtime errors, no memory leakage...

Although it took quite some efforts to make it working like that - be
prepared to spend one-two weeks of intensive development - just to learn and
master TPL development and catch and fix all kinds of "race conditions". It
happened I have had to write a tiny "framework" on top of TPL - that handles
initialization of TPL tasks, keeping and reporting status, logging, running
tasks asynchronously (main usage scenario) or synchronously (used for
testing) etc. This "framework" is not yet ready for sharing - maybe I will
share it "one fine day" if anybody proposes a composite sample task to be
split into, say dozen of subtasks to be run in parallel, which I can
implement using mentioned above tiny "framework" and publish for
reviewing...

BTW, I have started to read "Professional Test Driven Development with C#:
Developing Real World Applications with TDD"  by James Bender and Jeff
McWheter
(http://www.amazon.com/Professional-Test-Driven-Development-Applications/dp/
047064320X) and do agree with review you can find on Amazon - "It is one of
the best development books I have ever read and I highly recommend it" (I
personally do try to follow TDD approach for almost five years now - and it
works well for me amd my customers' projects (strict deadlines, "bad coding
habits", inertia etc. do disturb me to follow TDD "fanatically") but I have
never seen such a good, concise and practical book for .NET C# TDD
development - I second almost every word of it - I wish I had written one
like that :))

Thank you.

No:

Unfortunately Visual Studio LightSwitch 2011 will not be included in the Action Pack.

Hi Shamil

For a small project I recalled LightSwitch and wondered if it had moved anywhere.
It has, and has even been labeled Go Live. I guess it means some kind of improved level of support.

That took me a couple of minutes - and another couple to copy and paste the links and post these here.
Then I browsed the development pages a little and people and the team seem quite active.

But I still miss the time for testing ...

Subject: [dba-VB] SQL Server compression
Message-ID: <4E650719.7020301@colbyconsulting.com>

The other day I populated the second socket of my (AMD) server with another 8 core chip.  With cores 
to spare I decided to give compression a whirl.  I am finding a lot of stuff out there now saying 
that it reduces the I/O a ton and that if you are not cpu limited then it makes the database faster 
because more stuff fits into memory.  Basically the objective is to get as much of the stuff that is 
being actively used to stay resident in memory.

One immediate benefit is that it cuts the total size of my databases on disk roughly in half.  This 
is a good thing because I keep the major players on SSD which is expensive.  Keeping them compressed 
means that I have more room on the SSD.

When I got into this business in October 2004 I had servers with AMD single core 3.8 ghz and 4 gigs 
or RAM running x32 windows and sql server.  I was trying to run count queries on 100 gb databases 
and while it worked, it was... not fast. I would run counts that took a half hour.

Through knowledge acquired on these lists I rebuilt my database tables, learned indexing, and made 
the databases much more efficient.

Seven years later I have 16 cores and 32 gigs RAM running X64 windows and SQL server.  A year ago I 
bought 32 gigs of DDR3 1300 registered ECC ram for $1000.  Today I ordered another 32 gigs for $400.

It is incredible to me that using brute force and ignorance, I can now keep multiple largish 
databases entirely in memory.  While I have no benchmarks recorded to compare yesteryear to today, I 
am doing things in minutes or even seconds that would have taken me a half hour or even hours seven 
years ago.

These are exciting times.

BTW I found something called GeekBench which I ran on my machine.  It is the only thing I have found 
that is a reasonable cost ($13) to give me numbers to compare to others.  My Geekbench number is 
~13,500, and it pointed out to me that I am currently running the server with 1/2 of the memory 
"bandwidth" I could be getting (the biggest reason I am adding more).

I had 4 DIMMS and a single processor.  The processor has a 4 port memory controller.  When I added 
the new processor I redistributed the memory so that each chip had 1/2 of the memory (2 dimms) but 
in doing so I "crippled" the memory controller.  The price of memory is dropping like a rock so now 
seems like a good time to top up.  It will be interesting to see what filling out the memory 
controller does to the numbers.

I "retired" my previous server to be my VM server, and it just occurred to me that I can run 
Geekbench on that to get a comparison of my previous server against my current server.  My previous 
server is an AMD quad core with 16 gigs of RAM and the geekbench on that is 7469.

Hi Gustav --

Thank you for your information.

I personally do not plan to work (and even to play) with MS LightSwitch.
I can be wrong - but as far as I have heard/read HTML5/CSS3/JavaScript will
soon (in a few years?) make Adobe Flash and SilverLight(?) a kind of
"obsolete" technologies:

http://ntt.cc/2010/03/15/will-html5-css-javascript-really-be-flash-and-silve
rlight-killer.html

and iPad doesn't support Adobe Flash (does it support Silverlight?) - and
according to the referred above article everybody will soon have an iPad :)

Thank you.

I asked MAPS if Visual Studio LightSwitch 2011 (now trial and
purchase-ware):

http://www.microsoftstore.com/lightswitch 

will be included in the Microsoft Action Pack Development and Design
Subscription for 2011/2012?

No:

Unfortunately Visual Studio LightSwitch 2011 will not be included in the
Action Pack.

Visual Sutdio LightSwitch 2011 is Available to Levels: Developer AA; VS Pro

Hi Shamil

For a small project I recalled LightSwitch and wondered if it had moved
anywhere.
It has, and has even been labeled Go Live. I guess it means some kind of
improved level of support.

That took me a couple of minutes - and another couple to copy and paste the
links and post these here.
Then I browsed the development pages a little and people and the team seem
quite active.

But I still miss the time for testing ...

Hi Gustav --

How do you manage to find free time to watch for and to even try(?!) Beta
releases of MS software?
I can't find that free time...

Thank you.

Hi all

Here is a better, though still brief, introduction to the new beta:

http://social.msdn.microsoft.com/Forums/en-US/lightswitchgeneral/threads
Click at the top under Announcements the topic:
Visual Studio LightSwitch Beta 2 Released with Go Live License!

<quote>
.. We'd also like to announce that Beta 2 comes with a "Go Live" license
which means you can now start using Visual Studio LightSwitch for production
projects </quote>

Hi members of "VS2010 SP1 club"

Then those interested in true RAD may proceed obtaining the recent
LightSwitch Beta 2 which requires VS2010 SP1:
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=cff6c4ef-a29a-4c
82-9a59-8a3bbb65ec3d 

The Beta 1 must be uninstalled first.
Apart from many minor improvements "too numerous to mention" as the team
tells, an interesting new feature is direct deployment to Windows/SQL Azure.

Also, the Visual Studio LightSwitch Beta 2 Training Kit:

Hi Shamil

No one knows, and so many smart opinions out there about what is "dead" or "hot". 
MS claims that Silverlight will remain a focus product but who knows?

Neither Silverlight, LightSwitch, or Access for that matter, is the answer for everything, but I find LightSwitch to be much of that Access should have been.

Most smartphone users will have an Android. I have a Windows Phone 7 and find it superior.

Hi Gustav --

Thank you for your information.

I personally do not plan to work (and even to play) with MS LightSwitch.
I can be wrong - but as far as I have heard/read HTML5/CSS3/JavaScript will
soon (in a few years?) make Adobe Flash and SilverLight(?) a kind of
"obsolete" technologies:

http://ntt.cc/2010/03/15/will-html5-css-javascript-really-be-flash-and-silverlight-killer.html

and iPad doesn't support Adobe Flash (does it support Silverlight?) - and
according to the referred above article everybody will soon have an iPad :)

Thank you.

Hi Gustav --

Yes, no one knows what technology will "fire" in the near future
I just noted I feel a bit "tired of custom MS technologies" - trying to make
money here using a limited (but huge - .NET framework IS huge) set of MS
technologies and to use as much as possible generally accepted software
development technologies, practices and standards...

BTW, I do plan to purchase Windows Phone 7/8 - if MS LightSwitch will be
able (isn't it yet?) to prototype/develop Windows Phone 7/8 apps I would
definitely try to use it...

Thank you.

P.S. ".NET Gadgeteer" and "3D printing" look very cool from here - imagine
one will be able to design and to "3d print" "home hand made" custom gadgets

The iPad doesn't support Silverlight any more than the iPhone does.  When
you arrive at a Silverlight web page, you get a message asking you to
install Silverlight, which of course you can't.

Hi Doug,

Thank you - this is why I'm "talking HTML5/CSS3/JavaScript" here - iPad is
rather popular here because of the current Russian president using it.
I do "wild guess" Windows Phone 7/8 will be also popular here when its
localized version will be released still I have to take into account Android
and iPhone users when developing mobile apps...

Hi Shamil

The goal for LightSwitch is RAD of Silverlight Line Of Business apps for simultaneous deployment as desktop and browser application as you prefer. It is not (yet) for phone development as far as I know.

For Windows Phone development you currently use the development kit for Visual Studio 2010 and the associated Phone simulator.

The Gadgeteer looks cool but expensive. And a little more mechanics is needed if you ask me - to make the Meccano of our time.

3D printing I saw in real life at an exhibition several years ago and was amazed. It was used to create prototypes of items for later plastic molding. Items were relatively "coarse" at that time, but I'm convinced that this technique will turn many things upside down. Just think of how laser printing replaced offset print in many areas and how video projectors have killed old days' slide projector - and currently movie projection in cinemas.

The key parameter of 3D printing is, of course, the strength of the produced items. This evolves rapidly. At one point, think how you could bring a 3D printer and a bunch of printing powder to Mars, then you can produce any item locally. The list goes on.

Hi Gustav --

Thank you for your information.

I personally do not plan to work (and even to play) with MS LightSwitch.
I can be wrong - but as far as I have heard/read HTML5/CSS3/JavaScript will
soon (in a few years?) make Adobe Flash and SilverLight(?) a kind of
"obsolete" technologies:

http://ntt.cc/2010/03/15/will-html5-css-javascript-really-be-flash-and-silve
rlight-killer.html

and iPad doesn't support Adobe Flash (does it support Silverlight?) - and
according to the referred above article everybody will soon have an iPad :)

Thank you.

Hi Shamil

For a small project I recalled LightSwitch and wondered if it had moved
anywhere.
It has, and has even been labeled Go Live. I guess it means some kind of
improved level of support.

That took me a couple of minutes - and another couple to copy and paste the
links and post these here.
Then I browsed the development pages a little and people and the team seem
quite active.

But I still miss the time for testing ...

That is another big reason to avoid proprietary software, as you never know

Hi Shamil

The iPad doesn't support Silverlight any more than the iPhone does.  When
you arrive at a Silverlight web page, you get a message asking you to
install Silverlight, which of course you can't.

Hi John

Not currently, but we do have a client with a heavily customized Access 97 application which we delivered summer 1999 and have expanded in steps through the years. This is for an organisation of dealers of agricultural machinery (combined harvesters, etc.) and as you can imagine, age is showing. It's not a question of reliability as the app has ran with zero errors or breakdowns. But new desktops we run with Windows 7 32-bit to avoid trouble with A97 and 64-bit OS, web interface is missing, etc. 

The office is only five people so budget is if not tight then limited and, as the app (three frontends actually with two backends for data and pictures) runs the full business, a replacement must be efficient and predictable to develop. However, the app contains nothing fancy - it's really a typical Line Of Business app taking care of everything a small organisation needs - exactly what LightSwitch is for.

So my plan is to model an introductory LS app to demonstrate how a single task could be performed and see if the client likes it. Then move on with a SQL Server 2008 backend (already running on their SBS).

If you should ask, we have no intention to move the app to Access 2010. I regard Access as a dead end for developers and the lack of a web interface other than SharePoint is a show-stopper.

Hi Shamil

I did consider that but funding will never be fat. The organisation counts only a few hundred members, and as the backends are only 150 MB I will face no scaling issue. It is exactly what LS is targeted for, so for this reason alone I will do the test. It may, of course, prove unsatisfactory in some way and if so I  will for sure choose the WinForms route which works very well for me.

We have one client where I have used the click-once deployment method and it works very well. Even the smallest modification, which I can code in minutes, gets deployed at once as it just requires a few default clicks and a password to the clients local FTP server and it has been published. It can't be easier and it just works.

Hello All,

I saw a presentation on Lightswitch a few months ago.  I have to say I was
very impressed.  IMO, Lightswitch was giving tools to common people that
enabled them to build web apps as fast as we built database apps in the 90's
with Access.

The presenter used the concept of two types of users / developers, a big D
and a little d.  The little d is the guy in the small business, or in the IT
hardware dept and he needs an app for raising Cap Ex.  In lightswitch he can
code that in 1 hour and he can get back to his Server room.  For the big D,
there are also lots of powerful tools that mean he can use lightswitch for a
lot of a software project.

It really reminded me of the 90's when C++ existed and then we get Access
with VBA.

Thanks

Mark

The first look of Windows 8 may be a bit of a curiosity. 

Actually, it is two products in one or a core with two distros...like Linux,
given say, Lime and Ubuntu, each interface looks completely different but
each has the same kernel. There will be the new default browser/cell phone
type interface and then there will be Windows7. 

http://www.theregister.co.uk/2011/09/13/windows_8_preview/

I think this product is an evolutionary product...One part says desktop PC
and the other says Web based browser. The interface is just a step on the
journey which will lead away from the desktop PC to an internet support
application. 

Many articles have been written saying it more bluntly, but this is the
formal acceptance and official agreement, on the part of Microsoft. They
have just acknowledged the truth and that is that the PC, as we know it, is
dead.

So boys and girls if you plan to be working in the computer industry, of the
future get your internet skills ready. Learn about web servers, internet
protocols, distributive databases, HTMLx, CSSx, JavaScript, web based
graphics and cloud based applications (and all the forth-coming
generations). 

It is going to be a thrilling ride as we launch off from the PC.

Maybe in the US where internet access is fast and bandiwdth is cheap.   It will be many years

Today I built a Windows XP SP3 VM (x32) and installed MySQL Community Edition.  I installed all the 
prereqs, the database and the ODBC connector.  The .Net connector refused to install due to missing 
.net 2.0 or 4.0.

I also installed the workbench.

It looks very foreign.  It is very foreign.  This is the part of new technology I hate, that first 
look - "I don't recognize a thing" feeling.

Being a vm, I have a boot drive and a data drive.  The boot is 30 gigs and the data is 60 gigs. 
Let's hope that is enough, though one would think so for small databases.

I am trying to learn enough to assist a client with evaluating MySQL for replacing his Access MDB 
data store.

For now I have to figure out how to create a database.  Is it the same concept as SQL Server?  A 
file or set of files where tables, indexes, views etc are stored?  I assumed there would be some 
visual designer that would allow me to create the db, then tables etc.  It looks like that stuff is 
in "SQL Development".

This thing looks pretty nice, but very different on the surface.

I run MySQL locally as part of a WAMP installation and remotely on our FreeBSD servers.

I use phpMyAdmin for all the administration.   It's a very intuitive interface.

It's possibly worth installing WAMP just for the phpMyAdmin.

Hi Shamil

I did consider that but funding will never be fat. The organisation counts
only a few hundred members, and as the backends are only 150 MB I will face
no scaling issue. It is exactly what LS is targeted for, so for this reason
alone I will do the test. It may, of course, prove unsatisfactory in some
way and if so I  will for sure choose the WinForms route which works very
well for me.

We have one client where I have used the click-once deployment method and it
works very well. Even the smallest modification, which I can code in
minutes, gets deployed at once as it just requires a few default clicks and
a password to the clients local FTP server and it has been published. It
can't be easier and it just works.

Hi Shamil

No, I haven't got that far.

My first guess was that the table schemes of Northwind perhaps didn't correlate 100% with that expected by LightSwitch.

But the link you provided tells that a separate instance of SQL Server Express 2005/2008 (not any other version) is required to support LS itself during development to not mix up "development data" with your application data (user data). 

That I didn't know about, and it may cause trouble around where you use the development version of SQL Server 2008 for your local work.

Hi Gustav --

The issue was with table name [OrderDetail] and relationship name
OrderDetails collision - with  [OrderDetail] table getting OrderDetails
entities collection name (or something like that) when MS Lightswitch did
got generated EF data model - I have chenaged relationship name to
OrderItems - and voila' - the MS Lightswitch project compiles well now.

I have also got "hacked" the issue described here:

http://social.msdn.microsoft.com/Forums/en-US/lightswitchgeneral/thread/de2e
7ee5-fc82-4614-9245-4f4a9ae7185f

and I have now MS Lightswitch/Northwind tiny sample app with five
search/view/edit forms/secreens running locally under Visual Studio:

http://smsconsulting.spb.ru/test/s1.png
http://smsconsulting.spb.ru/test/s2.png
http://smsconsulting.spb.ru/test/s3.png
http://smsconsulting.spb.ru/test/s4.png
http://smsconsulting.spb.ru/test/s5.png

I will try to write more on that "hacking" in coming days if time will allow
and I will also try to publish this app...

Still don't understand why that MS SQL "__IntrinsicData" MS SQLExpress
instance can't be swicthed-off/"hacked" via MS Lightswitch development
interface/properties - hope it will be possible to do that in the coming MS
Lightswitch updates...

Thank you.

Hi Gustav --

The issue was with table name [OrderDetail] and relationship name
OrderDetails collision - with  [OrderDetail] table getting OrderDetails
entities collection name (or something like that) when MS Lightswitch did
got generated EF data model - I have chenaged relationship name to
OrderItems - and voila' - the MS Lightswitch project compiles well now.

I have also got "hacked" the issue described here:

http://social.msdn.microsoft.com/Forums/en-US/lightswitchgeneral/thread/de2e
7ee5-fc82-4614-9245-4f4a9ae7185f

and I have now MS Lightswitch/Northwind tiny sample app with five
search/view/edit forms/secreens running locally under Visual Studio:

I will try to write more on that "hacking" in coming days if time will allow
and I will also try to publish this app...

Still don't understand why that MS SQL "__IntrinsicData" MS SQLExpress
instance can't be swicthed-off/"hacked" via MS Lightswitch development
interface/properties - hope it will be possible to do that in the coming MS
Lightswitch updates...

Thank you.

Hi Shamil

Great! I knew they couldn't fool you.

Beth Massi of MS tells why SQL Express is needed:

<quote>
SQL Express is necessary because at development time, LightSwitch uses a User Instance of the database (this automatically attaches the database "on-the-fly" to the SQL service. Only SQL Express supports this option. If we didn't do it this way then you would not be able to easily share LightSwitch solutions with other developers or "F5" samples.

Hope this makes more sense now.
</quote>

Perhaps it makes sense, but I still don't understand why only the Express edition can carry out this "magic" which sounds pretty simple.

Thanks for the screen shots. Looks promising.

Well, I have read that - it does make some sense but imagine a use case
when datamodel/backend database exists and powerusers and developers have to
work just on LightSwitch forms, workflows etc. - the LightSwitch project
items, which are not  kept stored in backend DB - in this case binding to
SQLExpress looks unneeded and limiting - am I wrong? (that my "ranting"

Thank you, unfortunately I have to postpone that sample project work for a
couple of months - real customers' projects got higher priority here and
OpenXML SDK 2.0 I have just posted about in Access-D.
And I should probably not publish MS LightSwitch "hacking" information at
all - we will see - hopefully MS will soon fix this SQLExpress bidning issue
in the new MS LightSwitch versions/upgrades...

Thank you.

Subject: [dba-VB] Exporting Data to an Excel Spreadsheet
Message-ID: <004b01cc7d29$c82e2420$588a6c60$@comcast.net>

I have unfortunately discovered that there is no built-in method to create a
spreadsheet from within VB.Net, similar to DoCmd.TransferSpreadsheet like
there is in Access.

I've tried three different methods, but all have failed for one reason or
another.  There are numerous 3rd party solutions, but right now I just need
to do the basic step of creating a csv or xls file.

I'm starting with a Linq query (an IEnumerable).  I'd like to use this as
the starting point, but I could convert that to a DataTable, or to a DataSet
if needed.

If anyone does this successfully, please let me know.

Thanks!
Dan

Honestly, programmers these days!  If there's no "built in method",  they're lost.  That's what 
.Net does for your :-)
 
Grab some data ( any data)
Open a file for Output
Step through your data, building a comma separated list for each record and write it to the a 
file.

If you want to write the data into an actual Excel file, use COM.  Again, step through your 
data writing values out to the file,  You could base it on something like

Message-ID: <DB7C1015741D45A48F326233AACC2606@nant>


Hi All --

Just wanted to share my experience in using .NET 4.0 Task Parallel Library
(TPL):

http://msdn.microsoft.com/en-us/library/dd460693.aspx

I have recently developed and released to a customer an advanced WinForms
project/application having running dozen of parallel tasks

- getting data from external data sources/web services and local lookup
databases, 
- coordinating data, 
- CRUD-ing results into MS SQL 2008 back-end and log file, 
- displaying progress on WinForm...

I have used .NET 4.0 C# and TPL - the following classes:

- System.Threading.Tasks.Task
- System.Collections.Concurrent.ConcurrentBag<T>
- System.Collections.Concurrent.ConcurrentDictionary<TKey, TValue>
- System.Threading.Barrier
- C# lock statement

and 

- System.ComponentModel.BackgroundWorker to activate and run the main thread
"talking to" WinForms UI via Invoke.

TPL and related data structures and classes help to significantly simplify
coordination of the parallel tasks execution, still programming of
coordinated parallel tasks' execution is rather advanced activity - plan
one-two weeks of "learning by doing" if/when you'll find you wanted to use
TPL in your projects...

Thank you.

Hi Gustav --

Thank you for your question - yes, the final result/experience is positive
- the application is now up&running 24x7x365 on customer's system - no
runtime errors, no memory leakage...

Although it took quite some efforts to make it working like that - be
prepared to spend one-two weeks of intensive development - just to learn and
master TPL development and catch and fix all kinds of "race conditions". It
happened I have had to write a tiny "framework" on top of TPL - that handles
initialization of TPL tasks, keeping and reporting status, logging, running
tasks asynchronously (main usage scenario) or synchronously (used for
testing) etc. This "framework" is not yet ready for sharing - maybe I will
share it "one fine day" if anybody proposes a composite sample task to be
split into, say dozen of subtasks to be run in parallel, which I can
implement using mentioned above tiny "framework" and publish for
reviewing...

BTW, I have started to read "Professional Test Driven Development with C#:
Developing Real World Applications with TDD"  by James Bender and Jeff
McWheter
(http://www.amazon.com/Professional-Test-Driven-Development-Applications/dp/
047064320X) and do agree with review you can find on Amazon - "It is one of
the best development books I have ever read and I highly recommend it" (I
personally do try to follow TDD approach for almost five years now - and it
works well for me amd my customers' projects (strict deadlines, "bad coding
habits", inertia etc. do disturb me to follow TDD "fanatically") but I have
never seen such a good, concise and practical book for .NET C# TDD
development - I second almost every word of it - I wish I had written one
like that :))

Thank you.

No:

Unfortunately Visual Studio LightSwitch 2011 will not be included in the Action Pack.

Visual Sutdio LightSwitch 2011 is Available to Levels: Developer AA; VS Pro with MSDN (Retail); VS Premium with MSDN (MPN); BizSpark Admin; BizSpark; VS Ultimate with MSDN (VL); VS Premium with MSDN (VL); VS Pro with MSDN (VL); VS Premium with MSDN (Retail); VS Ultimate with MSDN (Retail); VS Ultimate with MSDN (MPN); MSDN AA Institution; VS Ultimate with MSDN (NFR FTE).

Hi Shamil

For a small project I recalled LightSwitch and wondered if it had moved anywhere.
It has, and has even been labeled Go Live. I guess it means some kind of improved level of support.

That took me a couple of minutes - and another couple to copy and paste the links and post these here.
Then I browsed the development pages a little and people and the team seem quite active.

But I still miss the time for testing ...

Message-ID: <4E650719.7020301@colbyconsulting.com>

The other day I populated the second socket of my (AMD) server with another 8 core chip.  With cores 
to spare I decided to give compression a whirl.  I am finding a lot of stuff out there now saying 
that it reduces the I/O a ton and that if you are not cpu limited then it makes the database faster 
because more stuff fits into memory.  Basically the objective is to get as much of the stuff that is 
being actively used to stay resident in memory.

One immediate benefit is that it cuts the total size of my databases on disk roughly in half.  This 
is a good thing because I keep the major players on SSD which is expensive.  Keeping them compressed 
means that I have more room on the SSD.

When I got into this business in October 2004 I had servers with AMD single core 3.8 ghz and 4 gigs 
or RAM running x32 windows and sql server.  I was trying to run count queries on 100 gb databases 
and while it worked, it was... not fast. I would run counts that took a half hour.

Through knowledge acquired on these lists I rebuilt my database tables, learned indexing, and made 
the databases much more efficient.

Seven years later I have 16 cores and 32 gigs RAM running X64 windows and SQL server.  A year ago I 
bought 32 gigs of DDR3 1300 registered ECC ram for $1000.  Today I ordered another 32 gigs for $400.

It is incredible to me that using brute force and ignorance, I can now keep multiple largish 
databases entirely in memory.  While I have no benchmarks recorded to compare yesteryear to today, I 
am doing things in minutes or even seconds that would have taken me a half hour or even hours seven 
years ago.

These are exciting times.

BTW I found something called GeekBench which I ran on my machine.  It is the only thing I have found 
that is a reasonable cost ($13) to give me numbers to compare to others.  My Geekbench number is 
~13,500, and it pointed out to me that I am currently running the server with 1/2 of the memory 
"bandwidth" I could be getting (the biggest reason I am adding more).

I had 4 DIMMS and a single processor.  The processor has a 4 port memory controller.  When I added 
the new processor I redistributed the memory so that each chip had 1/2 of the memory (2 dimms) but 
in doing so I "crippled" the memory controller.  The price of memory is dropping like a rock so now 
seems like a good time to top up.  It will be interesting to see what filling out the memory 
controller does to the numbers.

I "retired" my previous server to be my VM server, and it just occurred to me that I can run 
Geekbench on that to get a comparison of my previous server against my current server.  My previous 
server is an AMD quad core with 16 gigs of RAM and the geekbench on that is 7469.

Hi Gustav --

Thank you for your information.

I personally do not plan to work (and even to play) with MS LightSwitch.
I can be wrong - but as far as I have heard/read HTML5/CSS3/JavaScript will
soon (in a few years?) make Adobe Flash and SilverLight(?) a kind of
"obsolete" technologies:

http://ntt.cc/2010/03/15/will-html5-css-javascript-really-be-flash-and-silve
rlight-killer.html

and iPad doesn't support Adobe Flash (does it support Silverlight?) - and
according to the referred above article everybody will soon have an iPad :)

Thank you.

Hi Shamil

For a small project I recalled LightSwitch and wondered if it had moved
anywhere.
It has, and has even been labeled Go Live. I guess it means some kind of
improved level of support.

That took me a couple of minutes - and another couple to copy and paste the
links and post these here.
Then I browsed the development pages a little and people and the team seem
quite active.

But I still miss the time for testing ...

Hi Shamil

No one knows, and so many smart opinions out there about what is "dead" or "hot". 
MS claims that Silverlight will remain a focus product but who knows?

Neither Silverlight, LightSwitch, or Access for that matter, is the answer for everything, but I find LightSwitch to be much of that Access should have been.

Most smartphone users will have an Android. I have a Windows Phone 7 and find it superior.

Yes, no one knows what technology will "fire" in the near future
I just noted I feel a bit "tired of custom MS technologies" - trying to make
money here using a limited (but huge - .NET framework IS huge) set of MS
technologies and to use as much as possible generally accepted software
development technologies, practices and standards...

BTW, I do plan to purchase Windows Phone 7/8 - if MS LightSwitch will be
able (isn't it yet?) to prototype/develop Windows Phone 7/8 apps I would
definitely try to use it...

Hi Doug,

Thank you - this is why I'm "talking HTML5/CSS3/JavaScript" here - iPad is
rather popular here because of the current Russian president using it.
I do "wild guess" Windows Phone 7/8 will be also popular here when its
localized version will be released still I have to take into account Android
and iPhone users when developing mobile apps...

Hi Shamil

The goal for LightSwitch is RAD of Silverlight Line Of Business apps for simultaneous deployment as desktop and browser application as you prefer. It is not (yet) for phone development as far as I know.

For Windows Phone development you currently use the development kit for Visual Studio 2010 and the associated Phone simulator.

The Gadgeteer looks cool but expensive. And a little more mechanics is needed if you ask me - to make the Meccano of our time.

3D printing I saw in real life at an exhibition several years ago and was amazed. It was used to create prototypes of items for later plastic molding. Items were relatively "coarse" at that time, but I'm convinced that this technique will turn many things upside down. Just think of how laser printing replaced offset print in many areas and how video projectors have killed old days' slide projector - and currently movie projection in cinemas.

The key parameter of 3D printing is, of course, the strength of the produced items. This evolves rapidly. At one point, think how you could bring a 3D printer and a bunch of printing powder to Mars, then you can produce any item locally. The list goes on.

Hi Gustav --

Thank you for your information.

I personally do not plan to work (and even to play) with MS LightSwitch.
I can be wrong - but as far as I have heard/read HTML5/CSS3/JavaScript will
soon (in a few years?) make Adobe Flash and SilverLight(?) a kind of
"obsolete" technologies:

http://ntt.cc/2010/03/15/will-html5-css-javascript-really-be-flash-and-silve

and iPad doesn't support Adobe Flash (does it support Silverlight?) - and
according to the referred above article everybody will soon have an iPad :)

Thank you.

Hi Shamil

For a small project I recalled LightSwitch and wondered if it had moved
anywhere.
It has, and has even been labeled Go Live. I guess it means some kind of
improved level of support.

That took me a couple of minutes - and another couple to copy and paste the
links and post these here.
Then I browsed the development pages a little and people and the team seem
quite active.

But I still miss the time for testing ...

That is another big reason to avoid proprietary software, as you never know

Hi Shamil

The iPad doesn't support Silverlight any more than the iPhone does.  When
you arrive at a Silverlight web page, you get a message asking you to
install Silverlight, which of course you can't.

Hi John

Not currently, but we do have a client with a heavily customized Access 97 application which we delivered summer 1999 and have expanded in steps through the years. This is for an organisation of dealers of agricultural machinery (combined harvesters, etc.) and as you can imagine, age is showing. It's not a question of reliability as the app has ran with zero errors or breakdowns. But new desktops we run with Windows 7 32-bit to avoid trouble with A97 and 64-bit OS, web interface is missing, etc. 

The office is only five people so budget is if not tight then limited and, as the app (three frontends actually with two backends for data and pictures) runs the full business, a replacement must be efficient and predictable to develop. However, the app contains nothing fancy - it's really a typical Line Of Business app taking care of everything a small organisation needs - exactly what LightSwitch is for.

So my plan is to model an introductory LS app to demonstrate how a single task could be performed and see if the client likes it. Then move on with a SQL Server 2008 backend (already running on their SBS).

If you should ask, we have no intention to move the app to Access 2010. I regard Access as a dead end for developers and the lack of a web interface other than SharePoint is a show-stopper.

Hi Shamil

I did consider that but funding will never be fat. The organisation counts only a few hundred members, and as the backends are only 150 MB I will face no scaling issue. It is exactly what LS is targeted for, so for this reason alone I will do the test. It may, of course, prove unsatisfactory in some way and if so I  will for sure choose the WinForms route which works very well for me.

We have one client where I have used the click-once deployment method and it works very well. Even the smallest modification, which I can code in minutes, gets deployed at once as it just requires a few default clicks and a password to the clients local FTP server and it has been published. It can't be easier and it just works.

Hello All,

I saw a presentation on Lightswitch a few months ago.  I have to say I was
very impressed.  IMO, Lightswitch was giving tools to common people that
enabled them to build web apps as fast as we built database apps in the 90's
with Access.

The presenter used the concept of two types of users / developers, a big D
and a little d.  The little d is the guy in the small business, or in the IT
hardware dept and he needs an app for raising Cap Ex.  In lightswitch he can
code that in 1 hour and he can get back to his Server room.  For the big D,
there are also lots of powerful tools that mean he can use lightswitch for a
lot of a software project.

It really reminded me of the 90's when C++ existed and then we get Access
with VBA.

Thanks

Mark

The first look of Windows 8 may be a bit of a curiosity. 

Actually, it is two products in one or a core with two distros...like Linux,
given say, Lime and Ubuntu, each interface looks completely different but
each has the same kernel. There will be the new default browser/cell phone
type interface and then there will be Windows7. 

http://www.theregister.co.uk/2011/09/13/windows_8_preview/

I think this product is an evolutionary product...One part says desktop PC
and the other says Web based browser. The interface is just a step on the
journey which will lead away from the desktop PC to an internet support
application. 

Many articles have been written saying it more bluntly, but this is the
formal acceptance and official agreement, on the part of Microsoft. They
have just acknowledged the truth and that is that the PC, as we know it, is
dead.

So boys and girls if you plan to be working in the computer industry, of the
future get your internet skills ready. Learn about web servers, internet
protocols, distributive databases, HTMLx, CSSx, JavaScript, web based
graphics and cloud based applications (and all the forth-coming
generations). 

It is going to be a thrilling ride as we launch off from the PC.

Maybe in the US where internet access is fast and bandiwdth is cheap.   It will be many years 
before businesses in much of the world are prepared to go that way.

Subject: [dba-VB] MySQL
Message-ID: <4E752C1D.9060901@colbyconsulting.com>

Today I built a Windows XP SP3 VM (x32) and installed MySQL Community Edition.  I installed all the 
prereqs, the database and the ODBC connector.  The .Net connector refused to install due to missing 
.net 2.0 or 4.0.

I also installed the workbench.

It looks very foreign.  It is very foreign.  This is the part of new technology I hate, that first 
look - "I don't recognize a thing" feeling.

Being a vm, I have a boot drive and a data drive.  The boot is 30 gigs and the data is 60 gigs. 
Let's hope that is enough, though one would think so for small databases.

I am trying to learn enough to assist a client with evaluating MySQL for replacing his Access MDB 
data store.

For now I have to figure out how to create a database.  Is it the same concept as SQL Server?  A 
file or set of files where tables, indexes, views etc are stored?  I assumed there would be some 
visual designer that would allow me to create the db, then tables etc.  It looks like that stuff is 
in "SQL Development".

This thing looks pretty nice, but very different on the surface.

I run MySQL locally as part of a WAMP installation and remotely on our FreeBSD servers.

I use phpMyAdmin for all the administration.   It's a very intuitive interface.

It's possibly worth installing WAMP just for the phpMyAdmin.

Hi Shamil

I did consider that but funding will never be fat. The organisation counts
only a few hundred members, and as the backends are only 150 MB I will face
no scaling issue. It is exactly what LS is targeted for, so for this reason
alone I will do the test. It may, of course, prove unsatisfactory in some
way and if so I  will for sure choose the WinForms route which works very
well for me.

We have one client where I have used the click-once deployment method and it
works very well. Even the smallest modification, which I can code in
minutes, gets deployed at once as it just requires a few default clicks and
a password to the clients local FTP server and it has been published. It
can't be easier and it just works.

Hi Shamil

No, I haven't got that far.

My first guess was that the table schemes of Northwind perhaps didn't correlate 100% with that expected by LightSwitch.

But the link you provided tells that a separate instance of SQL Server Express 2005/2008 (not any other version) is required to support LS itself during development to not mix up "development data" with your application data (user data). 

That I didn't know about, and it may cause trouble around where you use the development version of SQL Server 2008 for your local work.

Hi Gustav --

The issue was with table name [OrderDetail] and relationship name
OrderDetails collision - with  [OrderDetail] table getting OrderDetails
entities collection name (or something like that) when MS Lightswitch did
got generated EF data model - I have chenaged relationship name to
OrderItems - and voila' - the MS Lightswitch project compiles well now.

I have also got "hacked" the issue described here:

http://social.msdn.microsoft.com/Forums/en-US/lightswitchgeneral/thread/de2e
7ee5-fc82-4614-9245-4f4a9ae7185f

and I have now MS Lightswitch/Northwind tiny sample app with five
search/view/edit forms/secreens running locally under Visual Studio:

http://smsconsulting.spb.ru/test/s3.png
http://smsconsulting.spb.ru/test/s4.png
http://smsconsulting.spb.ru/test/s5.png

I will try to write more on that "hacking" in coming days if time will allow
and I will also try to publish this app...

Still don't understand why that MS SQL "__IntrinsicData" MS SQLExpress
instance can't be swicthed-off/"hacked" via MS Lightswitch development
interface/properties - hope it will be possible to do that in the coming MS
Lightswitch updates...

Thank you.

Hi Shamil

No, I haven't got that far.

My first guess was that the table schemes of Northwind perhaps didn't
correlate 100% with that expected by LightSwitch.

But the link you provided tells that a separate instance of SQL Server
Express 2005/2008 (not any other version) is required to support LS itself
during development to not mix up "development data" with your application
data (user data). 

That I didn't know about, and it may cause trouble around where you use the
development version of SQL Server 2008 for your local work.

Hi All --

To avoid issues with ProductDetails table I have just checked it out from
external datasource while generating new MS Lightswitch project - and I have
got infamous:

Hi Shamil

Great! I knew they couldn't fool you.

Beth Massi of MS tells why SQL Express is needed:

<quote>
SQL Express is necessary because at development time, LightSwitch uses a User Instance of the database (this automatically attaches the database "on-the-fly" to the SQL service. Only SQL Express supports this option. If we didn't do it this way then you would not be able to easily share LightSwitch solutions with other developers or "F5" samples.

Hope this makes more sense now.
</quote>

Perhaps it makes sense, but I still don't understand why only the Express edition can carry out this "magic" which sounds pretty simple.

Thanks for the screen shots. Looks promising.

Well, I have read that - it does make some sense but imagine a use case
when datamodel/backend database exists and powerusers and developers have to
work just on LightSwitch forms, workflows etc. - the LightSwitch project
items, which are not  kept stored in backend DB - in this case binding to
SQLExpress looks unneeded and limiting - am I wrong? (that my "ranting"
sentence is directed to Beth Mossi not to you Gustav :) )

Yes, I don't understand that also.

Thank you, unfortunately I have to postpone that sample project work for a
couple of months - real customers' projects got higher priority here and
OpenXML SDK 2.0 I have just posted about in Access-D.
And I should probably not publish MS LightSwitch "hacking" information at
all - we will see - hopefully MS will soon fix this SQLExpress bidning issue
in the new MS LightSwitch versions/upgrades...

Thank you.

Subject: [dba-VB] Exporting Data to an Excel Spreadsheet
Message-ID: <004b01cc7d29$c82e2420$588a6c60$@comcast.net>

I have unfortunately discovered that there is no built-in method to create a
spreadsheet from within VB.Net, similar to DoCmd.TransferSpreadsheet like
there is in Access.

I've tried three different methods, but all have failed for one reason or
another.  There are numerous 3rd party solutions, but right now I just need
to do the basic step of creating a csv or xls file.

I'm starting with a Linq query (an IEnumerable).  I'd like to use this as
the starting point, but I could convert that to a DataTable, or to a DataSet
if needed.

If anyone does this successfully, please let me know.

Thanks!
Dan

Honestly, programmers these days!  If there's no "built in method",  they're lost.  That's what 
.Net does for your :-)
 
Grab some data ( any data)
Open a file for Output
Step through your data, building a comma separated list for each record and write it to the a 
file.

If you want to write the data into an actual Excel file, use COM.  Again, step through your 
data writing values out to the file,  You could base it on something like
