Message-ID: <91E8E248DC5845CBA678F51B568217E5@nant>

Hi All --

FYI: I have got used to format TimeStamp values this simple way (for
TimeStamp values less than a day):

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh:mm:ss}", ts);
System.Console.WriteLine(s);

and it worked well for VS2008/.NET 3.5 but when my project was converted to
VS2010SP1/.NET 4.0 I have got runtime error...

Proper TimeStamp formatting for my case should be {0:hh\\:mm\\:ss} :

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh\\:mm\\:ss}", ts);
System.Console.WriteLine(s);

Thank you.

Hi Shamil

So what you try to tell ... is that a colon on its own now is reserved for the use as the separator between the value and the format string?

Not just the colon, any separator:

<quote>
The custom TimeSpan format specifiers do not include placeholder separator symbols, such 
as the symbols that separate days from hours, hours from minutes, or seconds from 
fractional seconds. Instead, these symbols must be included in the custom format string as 
string literals. For example, "dd\.hh\:mm" defines a period (.) as the separator between days 
and hours, and a colon (:) as the separator between hours and minutes.

Hi Shamil

By the way, where does "TimeSpan" come from? Is it native to C# or custom by you?

Hi Stuart

Well, yes for the format string, but "any" separator is not (can not) be used to separate the value and the format string; it has to be a colon:

string s = string.Format("{0:hh\\:mm\\:ss}", ts);

Subject: [dba-VB] closing your connections
Message-ID: <BANLkTi=pYcQzgN1Dr5yn2ZHtS0E-8AAxRw@mail.gmail.com>

so I have a vb.net app (visual studio 2008) and I am making some sproc calls
like so:


 conn = New SqlConnection(My.MySettings.Default.dbConn)
            cmd = New SqlCommand("dbo.stp_PCO", conn)
            cmd.CommandType = CommandType.StoredProcedure
            conn.Open()
            da.SelectCommand = cmd
            da.Fill(dtCTable)

I've also tried closing my connections after usage by using the following
closing statments

dtCtable.Dispose()
dtClockTable = nothing
cmd.Dispose()
cmd = nothing
da.Dispose()
da = nothing
conn.close()
conn.Dispose()
conn = nothing

but when I check my sql server I still see sleeping entires in the activity
monitor suggesting that a connection is still active.  How do I sever the
connection completely?  I know a connection is alive and well because I
noticed that if I completely close the application the connection goes from
sleeping to gone.  I want my connections to close once the data has been
retrieved to allow the server to reuse that memory if needed.

in vb 6 it used to be so simple with just ado :(

your help is of course appreciated!

This is what I do with SQLCE when I need to modify the SDF, which shouldn't
differ too much from SQL Server:

        Dim strCEconn As String = "Data Source = " & strPath & strFileName
        Dim CEconn As SqlServerCe.SqlCeConnection = New
SqlServerCe.SqlCeConnection(strCEconn)
        CEconn.Open()
        Dim CEcmd As SqlServerCe.SqlCeCommand = CEconn.CreateCommand

        CEcmd.CommandText = "CREATE TABLE InvoiceOrderJunct([InvNo]
[nvarchar](8) NULL, [OrderID] [int], [AMNo] [nvarchar](10) NULL)"
        CEcmd.ExecuteNonQuery()

        CEcmd.Dispose()
        CEconn.Close()
        CEconn.Dispose()


I had to do this in one of my webservice functions, when we had weird
issues:


   <WebMethod()> _
Public Function InsertInvHdr(ByVal strInput As String, ByVal dsIn As
DataSet) As String

        Dim errNum As Integer
        Dim errMsg As String
        Dim myConnection As SqlConnection
        Dim myCommand As SqlCommand
        Dim row As DataRow

        Call fUnSecureString(strInput)

        Try
            'Following parameters are determined from strInput hash saved as
global variables
            myConnection = New SqlConnection("server=" & ServerName &
";uid=" & strUid & ";pwd=" & strPw& ";database=" & strDBname)
            myConnection.Open()
            myCommand = New SqlCommand
            myCommand.Connection = myConnection

            For Each row In dsIn.Tables(0).Rows
                myCommand.CommandText = "EXEC stpInsertIntoInvHdr '" &
row("ICNo").ToString() & "', '" & row("StoreNo").ToString() & "', '" &
row("CustNo").ToString()
                myCommand.ExecuteNonQuery()
            Next

            Return "InvHdr data inserted"
            'myConnection.Close()

'******************************************************************
            ' Added the 2 IF statements below on 8/4/2010 to see if it
clears out sleeping processes
            If (Not (myCommand) Is Nothing) Then
                myCommand.Dispose()
                myCommand = Nothing
            End If
            If (Not (myConnection) Is Nothing) Then
                myConnection.Close()
            End If
            '********************************************************
        Catch ex As Exception
            errNum = Err.Number
            errMsg = ex.Message
            Return "SQL/WS Error: WS.InsertInvHdr - " & errNum & ":" &
errMsg
            'Finally
            '   myConnection.Close()
        End Try
    End Function

Hi Gustav --

That was "miPtySing".
I meant .NET Framework's built-in System.TimeSpan struct not TimeStamp
(which doesn't exist).
I typed my code snippet from memory and my "brainputer"'s memory obviously
"got a Glueck" after a heavy duty working day of a large batch of VS2008
projects conversion to VS2010.

Correct sample code snippet should have been something like the following:

// Define TimeSpan value equal to
// 10 hours 11 minutes and 12 seconds
TimeSpan ts = new TimeSpan(10, 11, 12); 
// correct TimeSpan value formatting
string s = string.Format("Correct = {0:hh\\:mm\\:ss}", ts); 
System.Console.WriteLine(s);
// incorrect TimeSpan value formatting
try
{
    s = string.Format("Incorrect = {0:hh:mm:ss}", ts);
    System.Console.WriteLine(s);
}
catch (Exception ex)
{
    System.Console.WriteLine("Error: {0}", ex.Message);   
}

Thank you.

I'm not sure, I am closing and disposing my objects as I posted in my first
post...  but if I monitor the sql server I notice that the connection is
still active.(in awaiting sleep status but connected)  :-/

Subject: [dba-VB] A windows Service or Not a service?
Message-ID: <BANLkTik7A6UN=bkCrsz06WGL4QPpSrp8jg@mail.gmail.com>

I wrote a simple application that has a form and two buttons (along with a
timer).  My initial idea was that I would write this to be a windows service
so it would auto-start whenever a specific server would reboot etc.  The
purpose is that I need to get new records created by a "Vendor" application
and have them sent to a Second "Vendor" system.  I call a custom view that I
wrote that collects that last set of changes, then record by record calls a
webservice on our SAP system and pushes in the new changes.  My sql server
version is Sql Server 2000 so it's not as easy as just writing a soap object
to make the webservice call, I think it was much easier to just write the
app in c# and make the call that way, which works.  NOW for the tricky
part.  I wanted to write up the app to create a windows service installer so
that my admins could log into the windows server and either start or stop
the application, I also wanted to provide a gui view to the windows service
so that they could choose a different timer so it could run every 1 minute
(every 2 minutes, etc..) what ever they would choose.

after reading MS's description on windows service classes, I noticed that
supposedly the .Net Studio does not support this, but I've seen other apps
that DO provide a gui view to the windows service that they introduce.  so
my question to the group is, have you done this before? and if so how did
you go about it?

I too need to know this.  A service cannot directly support a user interface because if there is no 
one logged in there is no place to put the user interface (no screen to draw it).  My guess is that 
the user interface somehow calls functions to get information, or perhaps hooks a data "service" 
channel to read / write to the service application.

I'm wondering about that too, does that mean that I need to package "2"
applications?  one service with a port that will talk to the gui so that a
user can modify a specific setting (namely, how often it checks for new
records).

How about having a little config file that goes along with the service that
you could edit in notepad or xml note pad since .NET loves xml files.

Hi Francisco,

I have written a few real life WinServices working 24x7x365 for a few years.
When a Windows Service Project is created its base class has code snippet as
the following:

public partial class MyService : ServiceBase
{
 ...
       protected override void OnCustomCommand(int command)
        {
	switch(command)
             {
                case 503:
                      CustomCommand503();
                      return;
                 ...
              }	
        }
} 

It allows to define as many custom commands as you wanted to have.
You comunicate with a Windows Service using that custom commands' IDs - here
is a code snippet showing how to find your installed and runing Windows
Service and to pass to it your custom command ID:

public static void RunCustomServiceCommand(string serviceName, int
commandId)
{
    foreach (System.ServiceProcess.ServiceController service in
                System.ServiceProcess.ServiceController.GetServices())
    {
        // juts a test output - commented it when not needed
        System.Console.WriteLine("[{0}].[{1}].[{2}]", 
                                    service.MachineName, 
                                    service.ServiceName, 
                                    service.DisplayName);     
        if (string.Compare(service.ServiceName, serviceName, true) == 0)
        {
            service.ExecuteCommand(commandId);  
        }
    }
}

When I need to pass to a Windows Service more parameters than command id
then I use inderect/intermediate media: files, database tables, ... 

Another issue is to smoothly install, run, stop, uninstall  a Windows
service - there should be more info on Internet and MSDN about that
issues...

Thank you.

An NT Service (as you are calling it a Windows Service) is an executable
that is running on your machine and it has several different
'properties'.

First, the type of startup... either manual, disabled or automatic.
Automatic starts when you computer starts.  Disabled means the service
won't start.

Secondly, there is an 'interactive' option, that determines if a service
can run with an interface.  For this to work, it has to have user
credentials.

Services with a user interface can run into all sorts of issues. I
personally haven't built a service in .net yet, but have had lots of
experience with them in VB 6.

What you really want to do is build a service that has no interface, and
then build a program that 'controls' that program. This can be done in
many ways, either you can have the control change values in a database
or file, that the service utilizes, or you can create various 'talking'
methods, like named pipes, tcp/ip comms, etc, that allows the
controlling program to directly talk to the service.

wrote that collects that last set of changes, then record by record
calls a
webservice on our SAP system and pushes in the new changes.  My sql
server
version is Sql Server 2000 so it's not as easy as just writing a soap
object
to make the webservice call, I think it was much easier to just write
the
app in c# and make the call that way, which works.  NOW for the tricky
part.  I wanted to write up the app to create a windows service
installer so
that my admins could log into the windows server and either start or
stop
the application, I also wanted to provide a gui view to the windows
service
so that they could choose a different timer so it could run every 1
minute
(every 2 minutes, etc..) what ever they would choose.

after reading MS's description on windows service classes, I noticed
that
supposedly the .Net Studio does not support this, but I've seen other
apps
that DO provide a gui view to the windows service that they introduce.
so
my question to the group is, have you done this before? and if so how
did
you go about it?

The Windows service classes supported by the .NET Framework do not
support
interaction with interactive stations, that is, the logged-on user. The
.NET
Framework also does not include classes that represent stations and
desktops. If your Windows service must interact with other stations, you
will need to access the unmanaged Windows API. For more information, see
Window
Stations<http://msdn.microsoft.com/en-us/library/ms687096%28v=VS.90%29.a

Message-ID: <91E8E248DC5845CBA678F51B568217E5@nant>

Hi All --

FYI: I have got used to format TimeStamp values this simple way (for
TimeStamp values less than a day):

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh:mm:ss}", ts);
System.Console.WriteLine(s);

and it worked well for VS2008/.NET 3.5 but when my project was converted to
VS2010SP1/.NET 4.0 I have got runtime error...

Proper TimeStamp formatting for my case should be {0:hh\\:mm\\:ss} :

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh\\:mm\\:ss}", ts);
System.Console.WriteLine(s);

Hi Shamil

So what you try to tell ... is that a colon on its own now is reserved for the use as the separator between the value and the format string?

Not just the colon, any separator:

<quote>
The custom TimeSpan format specifiers do not include placeholder separator symbols, such 
as the symbols that separate days from hours, hours from minutes, or seconds from 
fractional seconds. Instead, these symbols must be included in the custom format string as 
string literals. For example, "dd\.hh\:mm" defines a period (.) as the separator between days 
and hours, and a colon (:) as the separator between hours and minutes.

Hi Stuart

Well, yes for the format string, but "any" separator is not (can not) be used to separate the value and the format string; it has to be a colon:

string s = string.Format("{0:hh\\:mm\\:ss}", ts);

Subject: [dba-VB] closing your connections
Message-ID: <BANLkTi=pYcQzgN1Dr5yn2ZHtS0E-8AAxRw@mail.gmail.com>

so I have a vb.net app (visual studio 2008) and I am making some sproc calls
like so:


 conn = New SqlConnection(My.MySettings.Default.dbConn)
            cmd = New SqlCommand("dbo.stp_PCO", conn)
            cmd.CommandType = CommandType.StoredProcedure
            conn.Open()
            da.SelectCommand = cmd
            da.Fill(dtCTable)

I've also tried closing my connections after usage by using the following
closing statments

dtCtable.Dispose()
dtClockTable = nothing
cmd.Dispose()
cmd = nothing
da.Dispose()
da = nothing
conn.close()
conn.Dispose()
conn = nothing

but when I check my sql server I still see sleeping entires in the activity
monitor suggesting that a connection is still active.  How do I sever the
connection completely?  I know a connection is alive and well because I
noticed that if I completely close the application the connection goes from
sleeping to gone.  I want my connections to close once the data has been
retrieved to allow the server to reuse that memory if needed.

in vb 6 it used to be so simple with just ado :(

your help is of course appreciated!

This is what I do with SQLCE when I need to modify the SDF, which shouldn't
differ too much from SQL Server:

        Dim strCEconn As String = "Data Source = " & strPath & strFileName
        Dim CEconn As SqlServerCe.SqlCeConnection = New
SqlServerCe.SqlCeConnection(strCEconn)
        CEconn.Open()
        Dim CEcmd As SqlServerCe.SqlCeCommand = CEconn.CreateCommand

        CEcmd.CommandText = "CREATE TABLE InvoiceOrderJunct([InvNo]
[nvarchar](8) NULL, [OrderID] [int], [AMNo] [nvarchar](10) NULL)"
        CEcmd.ExecuteNonQuery()

        CEcmd.Dispose()
        CEconn.Close()
        CEconn.Dispose()


I had to do this in one of my webservice functions, when we had weird
issues:


   <WebMethod()> _
Public Function InsertInvHdr(ByVal strInput As String, ByVal dsIn As
DataSet) As String

        Dim errNum As Integer
        Dim errMsg As String
        Dim myConnection As SqlConnection
        Dim myCommand As SqlCommand
        Dim row As DataRow

        Call fUnSecureString(strInput)

        Try
            'Following parameters are determined from strInput hash saved as
global variables
            myConnection = New SqlConnection("server=" & ServerName &
";uid=" & strUid & ";pwd=" & strPw& ";database=" & strDBname)
            myConnection.Open()
            myCommand = New SqlCommand
            myCommand.Connection = myConnection

            For Each row In dsIn.Tables(0).Rows
                myCommand.CommandText = "EXEC stpInsertIntoInvHdr '" &
row("ICNo").ToString() & "', '" & row("StoreNo").ToString() & "', '" &
row("CustNo").ToString()
                myCommand.ExecuteNonQuery()
            Next

            Return "InvHdr data inserted"
            'myConnection.Close()

'******************************************************************
            ' Added the 2 IF statements below on 8/4/2010 to see if it

            If (Not (myCommand) Is Nothing) Then

Hi Gustav --

That was "miPtySing".
I meant .NET Framework's built-in System.TimeSpan struct not TimeStamp
(which doesn't exist).
I typed my code snippet from memory and my "brainputer"'s memory obviously
"got a Glueck" after a heavy duty working day of a large batch of VS2008
projects conversion to VS2010.

Correct sample code snippet should have been something like the following:

// Define TimeSpan value equal to
// 10 hours 11 minutes and 12 seconds
TimeSpan ts = new TimeSpan(10, 11, 12); 
// correct TimeSpan value formatting
string s = string.Format("Correct = {0:hh\\:mm\\:ss}", ts); 
System.Console.WriteLine(s);
// incorrect TimeSpan value formatting
try
{
    s = string.Format("Incorrect = {0:hh:mm:ss}", ts);
    System.Console.WriteLine(s);
}
catch (Exception ex)
{
    System.Console.WriteLine("Error: {0}", ex.Message);   
}

Thank you.

P.S. Sorry for delay with my reply - I've got a short vacation immediately

Subject: [dba-VB] FYI: TimeStamp formatting issue for VS2010/.NET	4.0
Message-ID: <sdf408c9.034@cactus.dk>

Hi Shamil

Ha ha, "got a Glueck", that explains!

Hi Gustav --

That was "miPtySing".
I meant .NET Framework's built-in System.TimeSpan struct not TimeStamp
(which doesn't exist).
I typed my code snippet from memory and my "brainputer"'s memory obviously
"got a Glueck" after a heavy duty working day of a large batch of VS2008
projects conversion to VS2010.

Correct sample code snippet should have been something like the following:

// Define TimeSpan value equal to
// 10 hours 11 minutes and 12 seconds
TimeSpan ts = new TimeSpan(10, 11, 12); 
// correct TimeSpan value formatting
string s = string.Format("Correct = {0:hh\\:mm\\:ss}", ts); 
System.Console.WriteLine(s);
// incorrect TimeSpan value formatting
try
{
    s = string.Format("Incorrect = {0:hh:mm:ss}", ts);
    System.Console.WriteLine(s);
}
catch (Exception ex)
{
    System.Console.WriteLine("Error: {0}", ex.Message);   
}

Thank you.

P.S. Sorry for delay with my reply - I've got a short vacation immediately
after I have posted to Access-D my original posting...

Hi Shamil

By the way, where does "TimeSpan" come from? Is it native to C# or custom by
you?

Hi All --

FYI: I have got used to format TimeStamp values this simple way (for
TimeStamp values less than a day):

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh:mm:ss}", ts); System.Console.WriteLine(s);

and it worked well for VS2008/.NET 3.5 but when my project was converted to
VS2010SP1/.NET 4.0 I have got runtime error...

Proper TimeStamp formatting for my case should be {0:hh\\:mm\\:ss} :

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh\\:mm\\:ss}", ts);
System.Console.WriteLine(s);

Thank you.

still active.(in awaiting sleep status but connected)  :-/

Subject: [dba-VB] A windows Service or Not a service?
Message-ID: <BANLkTik7A6UN=bkCrsz06WGL4QPpSrp8jg@mail.gmail.com>

I wrote a simple application that has a form and two buttons (along with a
timer).  My initial idea was that I would write this to be a windows service
so it would auto-start whenever a specific server would reboot etc.  The
purpose is that I need to get new records created by a "Vendor" application
and have them sent to a Second "Vendor" system.  I call a custom view that I
wrote that collects that last set of changes, then record by record calls a
webservice on our SAP system and pushes in the new changes.  My sql server
version is Sql Server 2000 so it's not as easy as just writing a soap object
to make the webservice call, I think it was much easier to just write the
app in c# and make the call that way, which works.  NOW for the tricky
part.  I wanted to write up the app to create a windows service installer so
that my admins could log into the windows server and either start or stop
the application, I also wanted to provide a gui view to the windows service
so that they could choose a different timer so it could run every 1 minute
(every 2 minutes, etc..) what ever they would choose.

after reading MS's description on windows service classes, I noticed that
supposedly the .Net Studio does not support this, but I've seen other apps
that DO provide a gui view to the windows service that they introduce.  so
my question to the group is, have you done this before? and if so how did
you go about it?

The Windows service classes supported by the .NET Framework do not support
interaction with interactive stations, that is, the logged-on user. The .NET
Framework also does not include classes that represent stations and
desktops. If your Windows service must interact with other stations, you
will need to access the unmanaged Windows API. For more information, see Window
Stations<http://msdn.microsoft.com/en-us/library/ms687096%28v=VS.90%29.aspx>and
Desktops<http://msdn.microsoft.com/en-us/library/ms682573%28v=VS.90%29.aspx>in
the Platform SDK documentation.

I too need to know this.  A service cannot directly support a user interface because if there is no 
one logged in there is no place to put the user interface (no screen to draw it).  My guess is that 
the user interface somehow calls functions to get information, or perhaps hooks a data "service" 
channel to read / write to the service application.

I'm wondering about that too, does that mean that I need to package "2"
applications?  one service with a port that will talk to the gui so that a
user can modify a specific setting (namely, how often it checks for new
records).

How about having a little config file that goes along with the service that
you could edit in notepad or xml note pad since .NET loves xml files.

Hi Francisco,

I have written a few real life WinServices working 24x7x365 for a few years.
When a Windows Service Project is created its base class has code snippet as
the following:

public partial class MyService : ServiceBase
{
 ...
       protected override void OnCustomCommand(int command)
        {
	switch(command)
             {
                case 503:
                      CustomCommand503();
                      return;
                 ...
              }	
        }
} 

It allows to define as many custom commands as you wanted to have.
You comunicate with a Windows Service using that custom commands' IDs - here
is a code snippet showing how to find your installed and runing Windows
Service and to pass to it your custom command ID:

public static void RunCustomServiceCommand(string serviceName, int
commandId)
{
    foreach (System.ServiceProcess.ServiceController service in
                System.ServiceProcess.ServiceController.GetServices())
    {
        // juts a test output - commented it when not needed
        System.Console.WriteLine("[{0}].[{1}].[{2}]", 
                                    service.MachineName, 
                                    service.ServiceName, 
                                    service.DisplayName);     
        if (string.Compare(service.ServiceName, serviceName, true) == 0)
        {
            service.ExecuteCommand(commandId);  
        }
    }
}

When I need to pass to a Windows Service more parameters than command id
then I use inderect/intermediate media: files, database tables, ... 

Another issue is to smoothly install, run, stop, uninstall  a Windows
service - there should be more info on Internet and MSDN about that
issues...

Thank you.

Subject: [dba-VB] A windows Service or Not a service?

I wrote a simple application that has a form and two buttons (along with a
timer).  My initial idea was that I would write this to be a windows service
so it would auto-start whenever a specific server would reboot etc.  The
purpose is that I need to get new records created by a "Vendor" application
and have them sent to a Second "Vendor" system.  I call a custom view that I
wrote that collects that last set of changes, then record by record calls a
webservice on our SAP system and pushes in the new changes.  My sql server
version is Sql Server 2000 so it's not as easy as just writing a soap object
to make the webservice call, I think it was much easier to just write the
app in c# and make the call that way, which works.  NOW for the tricky part.
I wanted to write up the app to create a windows service installer so that
my admins could log into the windows server and either start or stop the
application, I also wanted to provide a gui view to the windows service so
that they could choose a different timer so it could run every 1 minute
(every 2 minutes, etc..) what ever they would choose.

after reading MS's description on windows service classes, I noticed that
supposedly the .Net Studio does not support this, but I've seen other apps
that DO provide a gui view to the windows service that they introduce.  so
my question to the group is, have you done this before? and if so how did
you go about it?

The Windows service classes supported by the .NET Framework do not support
interaction with interactive stations, that is, the logged-on user. The .NET
Framework also does not include classes that represent stations and
desktops. If your Windows service must interact with other stations, you
will need to access the unmanaged Windows API. For more information, see

An NT Service (as you are calling it a Windows Service) is an executable
that is running on your machine and it has several different
'properties'.

First, the type of startup... either manual, disabled or automatic.
Automatic starts when you computer starts.  Disabled means the service
won't start.

Secondly, there is an 'interactive' option, that determines if a service
can run with an interface.  For this to work, it has to have user
credentials.

Services with a user interface can run into all sorts of issues. I
personally haven't built a service in .net yet, but have had lots of
experience with them in VB 6.

What you really want to do is build a service that has no interface, and
then build a program that 'controls' that program. This can be done in
many ways, either you can have the control change values in a database
or file, that the service utilizes, or you can create various 'talking'
methods, like named pipes, tcp/ip comms, etc, that allows the
controlling program to directly talk to the service.

Message-ID: <91E8E248DC5845CBA678F51B568217E5@nant>

Hi All --

FYI: I have got used to format TimeStamp values this simple way (for
TimeStamp values less than a day):

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh:mm:ss}", ts);
System.Console.WriteLine(s);

and it worked well for VS2008/.NET 3.5 but when my project was converted to
VS2010SP1/.NET 4.0 I have got runtime error...

Proper TimeStamp formatting for my case should be {0:hh\\:mm\\:ss} :

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh\\:mm\\:ss}", ts);
System.Console.WriteLine(s);

Hi Shamil

So what you try to tell ... is that a colon on its own now is reserved for the use as the separator between the value and the format string?

The custom TimeSpan format specifiers do not include placeholder separator symbols, such

Hi Stuart

Well, yes for the format string, but "any" separator is not (can not) be used to separate the value and the format string; it has to be a colon:

string s = string.Format("{0:hh\\:mm\\:ss}", ts);

Subject: [dba-VB] closing your connections
Message-ID: <BANLkTi=pYcQzgN1Dr5yn2ZHtS0E-8AAxRw@mail.gmail.com>

so I have a vb.net app (visual studio 2008) and I am making some sproc calls
like so:


 conn = New SqlConnection(My.MySettings.Default.dbConn)
            cmd = New SqlCommand("dbo.stp_PCO", conn)
            cmd.CommandType = CommandType.StoredProcedure
            conn.Open()
            da.SelectCommand = cmd
            da.Fill(dtCTable)

I've also tried closing my connections after usage by using the following
closing statments

dtCtable.Dispose()
dtClockTable = nothing
cmd.Dispose()
cmd = nothing
da.Dispose()
da = nothing
conn.close()
conn.Dispose()
conn = nothing

but when I check my sql server I still see sleeping entires in the activity
monitor suggesting that a connection is still active.  How do I sever the
connection completely?  I know a connection is alive and well because I
noticed that if I completely close the application the connection goes from
sleeping to gone.  I want my connections to close once the data has been
retrieved to allow the server to reuse that memory if needed.

in vb 6 it used to be so simple with just ado :(

your help is of course appreciated!

This is what I do with SQLCE when I need to modify the SDF, which shouldn't
differ too much from SQL Server:

        Dim strCEconn As String = "Data Source = " & strPath & strFileName
        Dim CEconn As SqlServerCe.SqlCeConnection = New
SqlServerCe.SqlCeConnection(strCEconn)
        CEconn.Open()
        Dim CEcmd As SqlServerCe.SqlCeCommand = CEconn.CreateCommand

        CEcmd.CommandText = "CREATE TABLE InvoiceOrderJunct([InvNo]
[nvarchar](8) NULL, [OrderID] [int], [AMNo] [nvarchar](10) NULL)"
        CEcmd.ExecuteNonQuery()

        CEcmd.Dispose()
        CEconn.Close()
        CEconn.Dispose()


I had to do this in one of my webservice functions, when we had weird
issues:


   <WebMethod()> _

        Dim errNum As Integer

Hi Gustav --

That was "miPtySing".
I meant .NET Framework's built-in System.TimeSpan struct not TimeStamp
(which doesn't exist).
I typed my code snippet from memory and my "brainputer"'s memory obviously
"got a Glueck" after a heavy duty working day of a large batch of VS2008
projects conversion to VS2010.

Correct sample code snippet should have been something like the following:

// Define TimeSpan value equal to
// 10 hours 11 minutes and 12 seconds
TimeSpan ts = new TimeSpan(10, 11, 12); 
// correct TimeSpan value formatting
string s = string.Format("Correct = {0:hh\\:mm\\:ss}", ts); 
System.Console.WriteLine(s);
// incorrect TimeSpan value formatting
try
{
    s = string.Format("Incorrect = {0:hh:mm:ss}", ts);
    System.Console.WriteLine(s);
}
catch (Exception ex)
{
    System.Console.WriteLine("Error: {0}", ex.Message);   
}

Thank you.

By the way, where does "TimeSpan" come from? Is it native to C# or custom by

Hi All --

FYI: I have got used to format TimeStamp values this simple way (for
TimeStamp values less than a day):

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh:mm:ss}", ts); System.Console.WriteLine(s);

and it worked well for VS2008/.NET 3.5 but when my project was converted to
VS2010SP1/.NET 4.0 I have got runtime error...

Proper TimeStamp formatting for my case should be {0:hh\\:mm\\:ss} :

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh\\:mm\\:ss}", ts);
System.Console.WriteLine(s);

I'm not sure, I am closing and disposing my objects as I posted in my first
post...  but if I monitor the sql server I notice that the connection is
still active.(in awaiting sleep status but connected)  :-/

Subject: [dba-VB] A windows Service or Not a service?
Message-ID: <BANLkTik7A6UN=bkCrsz06WGL4QPpSrp8jg@mail.gmail.com>

I wrote a simple application that has a form and two buttons (along with a
timer).  My initial idea was that I would write this to be a windows service
so it would auto-start whenever a specific server would reboot etc.  The
purpose is that I need to get new records created by a "Vendor" application
and have them sent to a Second "Vendor" system.  I call a custom view that I
wrote that collects that last set of changes, then record by record calls a
webservice on our SAP system and pushes in the new changes.  My sql server
version is Sql Server 2000 so it's not as easy as just writing a soap object
to make the webservice call, I think it was much easier to just write the
app in c# and make the call that way, which works.  NOW for the tricky
part.  I wanted to write up the app to create a windows service installer so
that my admins could log into the windows server and either start or stop
the application, I also wanted to provide a gui view to the windows service
so that they could choose a different timer so it could run every 1 minute
(every 2 minutes, etc..) what ever they would choose.

after reading MS's description on windows service classes, I noticed that
supposedly the .Net Studio does not support this, but I've seen other apps
that DO provide a gui view to the windows service that they introduce.  so
my question to the group is, have you done this before? and if so how did
you go about it?

The Windows service classes supported by the .NET Framework do not support
interaction with interactive stations, that is, the logged-on user. The .NET
Framework also does not include classes that represent stations and
desktops. If your Windows service must interact with other stations, you
will need to access the unmanaged Windows API. For more information, see Window
Stations<http://msdn.microsoft.com/en-us/library/ms687096%28v=VS.90%29.aspx>and
Desktops<http://msdn.microsoft.com/en-us/library/ms682573%28v=VS.90%29.aspx>in
the Platform SDK documentation.

I too need to know this.  A service cannot directly support a user interface because if there is no 
one logged in there is no place to put the user interface (no screen to draw it).  My guess is that 
the user interface somehow calls functions to get information, or perhaps hooks a data "service" 
channel to read / write to the service application.

I'm wondering about that too, does that mean that I need to package "2"
applications?  one service with a port that will talk to the gui so that a
user can modify a specific setting (namely, how often it checks for new
records).

How about having a little config file that goes along with the service that
you could edit in notepad or xml note pad since .NET loves xml files.

I'm wondering about that too, does that mean that I need to package "2"
applications?  one service with a port that will talk to the gui so that a
user can modify a specific setting (namely, how often it checks for new
records).

Hi Francisco,

I have written a few real life WinServices working 24x7x365 for a few years.
When a Windows Service Project is created its base class has code snippet as
the following:

public partial class MyService : ServiceBase
{
 ...
       protected override void OnCustomCommand(int command)
        {
	switch(command)
             {
                case 503:
                      CustomCommand503();
                      return;
                 ...
              }	
        }
} 

It allows to define as many custom commands as you wanted to have.
You comunicate with a Windows Service using that custom commands' IDs - here
is a code snippet showing how to find your installed and runing Windows
Service and to pass to it your custom command ID:

public static void RunCustomServiceCommand(string serviceName, int
commandId)
{
    foreach (System.ServiceProcess.ServiceController service in
                System.ServiceProcess.ServiceController.GetServices())
    {
        // juts a test output - commented it when not needed
        System.Console.WriteLine("[{0}].[{1}].[{2}]", 
                                    service.MachineName, 
                                    service.ServiceName, 
                                    service.DisplayName);     
        if (string.Compare(service.ServiceName, serviceName, true) == 0)
        {
            service.ExecuteCommand(commandId);  
        }
    }
}

When I need to pass to a Windows Service more parameters than command id
then I use inderect/intermediate media: files, database tables, ... 

Another issue is to smoothly install, run, stop, uninstall  a Windows
service - there should be more info on Internet and MSDN about that
issues...

Thank you.

I wrote a simple application that has a form and two buttons (along with a

so it would auto-start whenever a specific server would reboot etc.  The
purpose is that I need to get new records created by a "Vendor" application

wrote that collects that last set of changes, then record by record calls a
webservice on our SAP system and pushes in the new changes.  My sql server

I wanted to write up the app to create a windows service installer so that

after reading MS's description on windows service classes, I noticed that
supposedly the .Net Studio does not support this, but I've seen other apps
that DO provide a gui view to the windows service that they introduce.  so
my question to the group is, have you done this before? and if so how did

The Windows service classes supported by the .NET Framework do not support
interaction with interactive stations, that is, the logged-on user. The .NET
Framework also does not include classes that represent stations and
desktops. If your Windows service must interact with other stations, you
will need to access the unmanaged Windows API. For more information, see

An NT Service (as you are calling it a Windows Service) is an executable
that is running on your machine and it has several different
'properties'.

First, the type of startup... either manual, disabled or automatic.
Automatic starts when you computer starts.  Disabled means the service
won't start.

Secondly, there is an 'interactive' option, that determines if a service
can run with an interface.  For this to work, it has to have user
credentials.

Services with a user interface can run into all sorts of issues. I
personally haven't built a service in .net yet, but have had lots of
experience with them in VB 6.

What you really want to do is build a service that has no interface, and
then build a program that 'controls' that program. This can be done in
many ways, either you can have the control change values in a database
or file, that the service utilizes, or you can create various 'talking'
methods, like named pipes, tcp/ip comms, etc, that allows the
controlling program to directly talk to the service.

Message-ID: <91E8E248DC5845CBA678F51B568217E5@nant>

Hi All --

FYI: I have got used to format TimeStamp values this simple way (for
TimeStamp values less than a day):

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh:mm:ss}", ts);
System.Console.WriteLine(s);

and it worked well for VS2008/.NET 3.5 but when my project was converted to
VS2010SP1/.NET 4.0 I have got runtime error...

Proper TimeStamp formatting for my case should be {0:hh\\:mm\\:ss} :

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh\\:mm\\:ss}", ts);
System.Console.WriteLine(s);

Hi Shamil

So what you try to tell ... is that a colon on its own now is reserved for the use as the separator between the value and the format string?

Not just the colon, any separator:

<quote>
The custom TimeSpan format specifiers do not include placeholder separator symbols, such 
as the symbols that separate days from hours, hours from minutes, or seconds from 
fractional seconds. Instead, these symbols must be included in the custom format string as 
string literals. For example, "dd\.hh\:mm" defines a period (.) as the separator between days 
and hours, and a colon (:) as the separator between hours and minutes.

Subject: [dba-VB] FYI: TimeStamp formatting issue for VS2010/.NET	4.0

Hi Shamil

By the way, where does "TimeSpan" come from? Is it native to C# or custom by you?

Hi All --

FYI: I have got used to format TimeStamp values this simple way (for
TimeStamp values less than a day):

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh:mm:ss}", ts);
System.Console.WriteLine(s);

and it worked well for VS2008/.NET 3.5 but when my project was converted to
VS2010SP1/.NET 4.0 I have got runtime error...

Proper TimeStamp formatting for my case should be {0:hh\\:mm\\:ss} :

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh\\:mm\\:ss}", ts);
System.Console.WriteLine(s);

Thank you.

Hi Stuart

Well, yes for the format string, but "any" separator is not (can not) be used to separate the value and the format string; it has to be a colon:

string s = string.Format("{0:hh\\:mm\\:ss}", ts);

Not just the colon, any separator:

<quote>
The custom TimeSpan format specifiers do not include placeholder separator symbols, such 
as the symbols that separate days from hours, hours from minutes, or seconds from 
fractional seconds. Instead, these symbols must be included in the custom format string as 
string literals. For example, "dd\.hh\:mm" defines a period (.) as the separator between days 
and hours, and a colon (:) as the separator between hours and minutes.

Subject: [dba-VB] closing your connections
Message-ID: <BANLkTi=pYcQzgN1Dr5yn2ZHtS0E-8AAxRw@mail.gmail.com>

so I have a vb.net app (visual studio 2008) and I am making some sproc calls
like so:


 conn = New SqlConnection(My.MySettings.Default.dbConn)
            cmd = New SqlCommand("dbo.stp_PCO", conn)
            cmd.CommandType = CommandType.StoredProcedure
            conn.Open()
            da.SelectCommand = cmd
            da.Fill(dtCTable)

I've also tried closing my connections after usage by using the following
closing statments

dtCtable.Dispose()
dtClockTable = nothing
cmd.Dispose()
cmd = nothing
da.Dispose()
da = nothing
conn.close()
conn.Dispose()
conn = nothing

but when I check my sql server I still see sleeping entires in the activity
monitor suggesting that a connection is still active.  How do I sever the
connection completely?  I know a connection is alive and well because I
noticed that if I completely close the application the connection goes from
sleeping to gone.  I want my connections to close once the data has been
retrieved to allow the server to reuse that memory if needed.

in vb 6 it used to be so simple with just ado :(

your help is of course appreciated!

This is what I do with SQLCE when I need to modify the SDF, which shouldn't
differ too much from SQL Server:

        Dim strCEconn As String = "Data Source = " & strPath & strFileName
        Dim CEconn As SqlServerCe.SqlCeConnection = New
SqlServerCe.SqlCeConnection(strCEconn)
        CEconn.Open()
        Dim CEcmd As SqlServerCe.SqlCeCommand = CEconn.CreateCommand

        CEcmd.CommandText = "CREATE TABLE InvoiceOrderJunct([InvNo]
[nvarchar](8) NULL, [OrderID] [int], [AMNo] [nvarchar](10) NULL)"
        CEcmd.ExecuteNonQuery()

        CEcmd.Dispose()
        CEconn.Close()
        CEconn.Dispose()


I had to do this in one of my webservice functions, when we had weird
issues:


   <WebMethod()> _
Public Function InsertInvHdr(ByVal strInput As String, ByVal dsIn As
DataSet) As String

        Dim errNum As Integer
        Dim errMsg As String
        Dim myConnection As SqlConnection
        Dim myCommand As SqlCommand
        Dim row As DataRow

        Call fUnSecureString(strInput)

        Try
            'Following parameters are determined from strInput hash saved as
global variables
            myConnection = New SqlConnection("server=" & ServerName &
";uid=" & strUid & ";pwd=" & strPw& ";database=" & strDBname)
            myConnection.Open()
            myCommand = New SqlCommand
            myCommand.Connection = myConnection

            For Each row In dsIn.Tables(0).Rows
                myCommand.CommandText = "EXEC stpInsertIntoInvHdr '" &
row("ICNo").ToString() & "', '" & row("StoreNo").ToString() & "', '" &
row("CustNo").ToString()
                myCommand.ExecuteNonQuery()
            Next

            Return "InvHdr data inserted"
            'myConnection.Close()

'******************************************************************
            ' Added the 2 IF statements below on 8/4/2010 to see if it
clears out sleeping processes
            If (Not (myCommand) Is Nothing) Then
                myCommand.Dispose()
                myCommand = Nothing
            End If
            If (Not (myConnection) Is Nothing) Then
                myConnection.Close()
            End If
            '********************************************************
        Catch ex As Exception
            errNum = Err.Number
            errMsg = ex.Message
            Return "SQL/WS Error: WS.InsertInvHdr - " & errNum & ":" &

            'Finally

Hi Gustav --

That was "miPtySing".
I meant .NET Framework's built-in System.TimeSpan struct not TimeStamp
(which doesn't exist).
I typed my code snippet from memory and my "brainputer"'s memory obviously
"got a Glueck" after a heavy duty working day of a large batch of VS2008
projects conversion to VS2010.

Correct sample code snippet should have been something like the following:

// Define TimeSpan value equal to
// 10 hours 11 minutes and 12 seconds
TimeSpan ts = new TimeSpan(10, 11, 12); 
// correct TimeSpan value formatting
string s = string.Format("Correct = {0:hh\\:mm\\:ss}", ts); 
System.Console.WriteLine(s);
// incorrect TimeSpan value formatting
try
{
    s = string.Format("Incorrect = {0:hh:mm:ss}", ts);
    System.Console.WriteLine(s);
}
catch (Exception ex)
{
    System.Console.WriteLine("Error: {0}", ex.Message);   
}

Thank you.

I'm not sure, I am closing and disposing my objects as I posted in my first
post...  but if I monitor the sql server I notice that the connection is
still active.(in awaiting sleep status but connected)  :-/

Subject: [dba-VB] A windows Service or Not a service?
Message-ID: <BANLkTik7A6UN=bkCrsz06WGL4QPpSrp8jg@mail.gmail.com>

I wrote a simple application that has a form and two buttons (along with a
timer).  My initial idea was that I would write this to be a windows service
so it would auto-start whenever a specific server would reboot etc.  The
purpose is that I need to get new records created by a "Vendor" application
and have them sent to a Second "Vendor" system.  I call a custom view that I
wrote that collects that last set of changes, then record by record calls a
webservice on our SAP system and pushes in the new changes.  My sql server
version is Sql Server 2000 so it's not as easy as just writing a soap object
to make the webservice call, I think it was much easier to just write the
app in c# and make the call that way, which works.  NOW for the tricky
part.  I wanted to write up the app to create a windows service installer so
that my admins could log into the windows server and either start or stop
the application, I also wanted to provide a gui view to the windows service
so that they could choose a different timer so it could run every 1 minute
(every 2 minutes, etc..) what ever they would choose.

after reading MS's description on windows service classes, I noticed that
supposedly the .Net Studio does not support this, but I've seen other apps
that DO provide a gui view to the windows service that they introduce.  so
my question to the group is, have you done this before? and if so how did

The Windows service classes supported by the .NET Framework do not support
interaction with interactive stations, that is, the logged-on user. The .NET
Framework also does not include classes that represent stations and
desktops. If your Windows service must interact with other stations, you
will need to access the unmanaged Windows API. For more information, see Window

I too need to know this.  A service cannot directly support a user interface because if there is no 
one logged in there is no place to put the user interface (no screen to draw it).  My guess is that 
the user interface somehow calls functions to get information, or perhaps hooks a data "service" 
channel to read / write to the service application.

I'm wondering about that too, does that mean that I need to package "2"
applications?  one service with a port that will talk to the gui so that a
user can modify a specific setting (namely, how often it checks for new
records).

How about having a little config file that goes along with the service that
you could edit in notepad or xml note pad since .NET loves xml files.

Hi Francisco,

I have written a few real life WinServices working 24x7x365 for a few years.
When a Windows Service Project is created its base class has code snippet as
the following:

public partial class MyService : ServiceBase
{
 ...
       protected override void OnCustomCommand(int command)
        {
	switch(command)
             {
                case 503:
                      CustomCommand503();
                      return;
                 ...
              }	
        }
} 

It allows to define as many custom commands as you wanted to have.
You comunicate with a Windows Service using that custom commands' IDs - here
is a code snippet showing how to find your installed and runing Windows
Service and to pass to it your custom command ID:

public static void RunCustomServiceCommand(string serviceName, int
commandId)
{
    foreach (System.ServiceProcess.ServiceController service in
                System.ServiceProcess.ServiceController.GetServices())
    {
        // juts a test output - commented it when not needed
        System.Console.WriteLine("[{0}].[{1}].[{2}]", 
                                    service.MachineName, 
                                    service.ServiceName, 
                                    service.DisplayName);     
        if (string.Compare(service.ServiceName, serviceName, true) == 0)
        {
            service.ExecuteCommand(commandId);  
        }
    }
}

When I need to pass to a Windows Service more parameters than command id
then I use inderect/intermediate media: files, database tables, ... 

Another issue is to smoothly install, run, stop, uninstall  a Windows
service - there should be more info on Internet and MSDN about that
issues...

Thank you.

An NT Service (as you are calling it a Windows Service) is an executable
that is running on your machine and it has several different
'properties'.

First, the type of startup... either manual, disabled or automatic.
Automatic starts when you computer starts.  Disabled means the service
won't start.

Secondly, there is an 'interactive' option, that determines if a service
can run with an interface.  For this to work, it has to have user
credentials.

Services with a user interface can run into all sorts of issues. I
personally haven't built a service in .net yet, but have had lots of
experience with them in VB 6.

What you really want to do is build a service that has no interface, and
then build a program that 'controls' that program. This can be done in
many ways, either you can have the control change values in a database
or file, that the service utilizes, or you can create various 'talking'
methods, like named pipes, tcp/ip comms, etc, that allows the
controlling program to directly talk to the service.

Nope, too much money for me.

If they would do it for $199 I would have it on order already.

LOL! Give it a couple of months. It'll be on clearance at Fry's.

Nope, too much money for me.

If they would do it for $199 I would have it on order already.

Message-ID: <91E8E248DC5845CBA678F51B568217E5@nant>

Hi All --

FYI: I have got used to format TimeStamp values this simple way (for
TimeStamp values less than a day):

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh:mm:ss}", ts);
System.Console.WriteLine(s);

and it worked well for VS2008/.NET 3.5 but when my project was converted to
VS2010SP1/.NET 4.0 I have got runtime error...

Proper TimeStamp formatting for my case should be {0:hh\\:mm\\:ss} :

TimeStamp ts = new TimeStamp(10,11,12);
string s = string.Format("{0:hh\\:mm\\:ss}", ts);
System.Console.WriteLine(s);

Thank you.

Hi Shamil

So what you try to tell ... is that a colon on its own now is reserved for the use as the separator between the value and the format string?

Not just the colon, any separator:

<quote>
The custom TimeSpan format specifiers do not include placeholder separator symbols, such 
as the symbols that separate days from hours, hours from minutes, or seconds from 
fractional seconds. Instead, these symbols must be included in the custom format string as 
string literals. For example, "dd\.hh\:mm" defines a period (.) as the separator between days 
and hours, and a colon (:) as the separator between hours and minutes.

Hi Stuart

Well, yes for the format string, but "any" separator is not (can not) be used to separate the value and the format string; it has to be a colon:

string s = string.Format("{0:hh\\:mm\\:ss}", ts);

Subject: [dba-VB] closing your connections
Message-ID: <BANLkTi=pYcQzgN1Dr5yn2ZHtS0E-8AAxRw@mail.gmail.com>

so I have a vb.net app (visual studio 2008) and I am making some sproc calls
like so:


 conn = New SqlConnection(My.MySettings.Default.dbConn)
            cmd = New SqlCommand("dbo.stp_PCO", conn)
            cmd.CommandType = CommandType.StoredProcedure
            conn.Open()
            da.SelectCommand = cmd
            da.Fill(dtCTable)

I've also tried closing my connections after usage by using the following
closing statments

dtCtable.Dispose()
dtClockTable = nothing
cmd.Dispose()
cmd = nothing
da.Dispose()
da = nothing
conn.close()
conn.Dispose()
conn = nothing

but when I check my sql server I still see sleeping entires in the activity
monitor suggesting that a connection is still active.  How do I sever the
connection completely?  I know a connection is alive and well because I
noticed that if I completely close the application the connection goes from
sleeping to gone.  I want my connections to close once the data has been
retrieved to allow the server to reuse that memory if needed.

in vb 6 it used to be so simple with just ado :(

your help is of course appreciated!

Message-ID: <BANLkTimdMvEjYF1wTBfHqP+3tXXXJ8DsSw@mail.gmail.com>

This is what I do with SQLCE when I need to modify the SDF, which shouldn't
differ too much from SQL Server:

        Dim strCEconn As String = "Data Source = " & strPath & strFileName
        Dim CEconn As SqlServerCe.SqlCeConnection = New
SqlServerCe.SqlCeConnection(strCEconn)
        CEconn.Open()
        Dim CEcmd As SqlServerCe.SqlCeCommand = CEconn.CreateCommand

        CEcmd.CommandText = "CREATE TABLE InvoiceOrderJunct([InvNo]
[nvarchar](8) NULL, [OrderID] [int], [AMNo] [nvarchar](10) NULL)"
        CEcmd.ExecuteNonQuery()

        CEcmd.Dispose()
        CEconn.Close()
        CEconn.Dispose()


I had to do this in one of my webservice functions, when we had weird
issues:


   <WebMethod()> _
Public Function InsertInvHdr(ByVal strInput As String, ByVal dsIn As
DataSet) As String

        Dim errNum As Integer
        Dim errMsg As String
        Dim myConnection As SqlConnection
        Dim myCommand As SqlCommand
        Dim row As DataRow

        Call fUnSecureString(strInput)

        Try
            'Following parameters are determined from strInput hash saved as
global variables
            myConnection = New SqlConnection("server=" & ServerName &
";uid=" & strUid & ";pwd=" & strPw& ";database=" & strDBname)
            myConnection.Open()
            myCommand = New SqlCommand
            myCommand.Connection = myConnection

            For Each row In dsIn.Tables(0).Rows
                myCommand.CommandText = "EXEC stpInsertIntoInvHdr '" &
row("ICNo").ToString() & "', '" & row("StoreNo").ToString() & "', '" &
row("CustNo").ToString()
                myCommand.ExecuteNonQuery()
            Next

            Return "InvHdr data inserted"
            'myConnection.Close()

'******************************************************************
            ' Added the 2 IF statements below on 8/4/2010 to see if it
clears out sleeping processes
            If (Not (myCommand) Is Nothing) Then
                myCommand.Dispose()
                myCommand = Nothing
            End If
            If (Not (myConnection) Is Nothing) Then
                myConnection.Close()
            End If
            '********************************************************
        Catch ex As Exception
            errNum = Err.Number
            errMsg = ex.Message
            Return "SQL/WS Error: WS.InsertInvHdr - " & errNum & ":" &
errMsg
            'Finally
            '   myConnection.Close()
        End Try
    End Function

Hi Gustav --

That was "miPtySing".
I meant .NET Framework's built-in System.TimeSpan struct not TimeStamp
(which doesn't exist).
I typed my code snippet from memory and my "brainputer"'s memory obviously
"got a Glueck" after a heavy duty working day of a large batch of VS2008
projects conversion to VS2010.

Correct sample code snippet should have been something like the following:

// Define TimeSpan value equal to
// 10 hours 11 minutes and 12 seconds
TimeSpan ts = new TimeSpan(10, 11, 12); 
// correct TimeSpan value formatting
string s = string.Format("Correct = {0:hh\\:mm\\:ss}", ts); 
System.Console.WriteLine(s);
// incorrect TimeSpan value formatting
try
{
    s = string.Format("Incorrect = {0:hh:mm:ss}", ts);
    System.Console.WriteLine(s);
}
catch (Exception ex)
{
    System.Console.WriteLine("Error: {0}", ex.Message);   
}

Thank you.

Subject: [dba-VB] A windows Service or Not a service?
Message-ID: <BANLkTik7A6UN=bkCrsz06WGL4QPpSrp8jg@mail.gmail.com>

I wrote a simple application that has a form and two buttons (along with a
timer).  My initial idea was that I would write this to be a windows service
so it would auto-start whenever a specific server would reboot etc.  The
purpose is that I need to get new records created by a "Vendor" application
and have them sent to a Second "Vendor" system.  I call a custom view that I
wrote that collects that last set of changes, then record by record calls a
webservice on our SAP system and pushes in the new changes.  My sql server
version is Sql Server 2000 so it's not as easy as just writing a soap object
to make the webservice call, I think it was much easier to just write the
app in c# and make the call that way, which works.  NOW for the tricky
part.  I wanted to write up the app to create a windows service installer so
that my admins could log into the windows server and either start or stop
the application, I also wanted to provide a gui view to the windows service
so that they could choose a different timer so it could run every 1 minute
(every 2 minutes, etc..) what ever they would choose.

after reading MS's description on windows service classes, I noticed that
supposedly the .Net Studio does not support this, but I've seen other apps
that DO provide a gui view to the windows service that they introduce.  so
my question to the group is, have you done this before? and if so how did
you go about it?

I too need to know this.  A service cannot directly support a user interface because if there is no 
one logged in there is no place to put the user interface (no screen to draw it).  My guess is that 
the user interface somehow calls functions to get information, or perhaps hooks a data "service" 
channel to read / write to the service application.

I'm wondering about that too, does that mean that I need to package "2"
applications?  one service with a port that will talk to the gui so that a
user can modify a specific setting (namely, how often it checks for new
records).

How about having a little config file that goes along with the service that
you could edit in notepad or xml note pad since .NET loves xml files.

Hi Francisco,

I have written a few real life WinServices working 24x7x365 for a few years.
When a Windows Service Project is created its base class has code snippet as
the following:

public partial class MyService : ServiceBase
{
 ...
       protected override void OnCustomCommand(int command)
        {
	switch(command)
             {
                case 503:
                      CustomCommand503();
                      return;
                 ...
              }	
        }
} 

It allows to define as many custom commands as you wanted to have.
You comunicate with a Windows Service using that custom commands' IDs - here
is a code snippet showing how to find your installed and runing Windows
Service and to pass to it your custom command ID:

public static void RunCustomServiceCommand(string serviceName, int
commandId)
{
    foreach (System.ServiceProcess.ServiceController service in
                System.ServiceProcess.ServiceController.GetServices())
    {
        // juts a test output - commented it when not needed
        System.Console.WriteLine("[{0}].[{1}].[{2}]", 
                                    service.MachineName, 
                                    service.ServiceName, 
                                    service.DisplayName);     
        if (string.Compare(service.ServiceName, serviceName, true) == 0)
        {
            service.ExecuteCommand(commandId);  
        }
    }
}

When I need to pass to a Windows Service more parameters than command id
then I use inderect/intermediate media: files, database tables, ... 

Another issue is to smoothly install, run, stop, uninstall  a Windows
service - there should be more info on Internet and MSDN about that
issues...

Thank you.

An NT Service (as you are calling it a Windows Service) is an executable
that is running on your machine and it has several different
'properties'.

First, the type of startup... either manual, disabled or automatic.
Automatic starts when you computer starts.  Disabled means the service
won't start.

Secondly, there is an 'interactive' option, that determines if a service
can run with an interface.  For this to work, it has to have user
credentials.

Services with a user interface can run into all sorts of issues. I
personally haven't built a service in .net yet, but have had lots of
experience with them in VB 6.

What you really want to do is build a service that has no interface, and
then build a program that 'controls' that program. This can be done in
many ways, either you can have the control change values in a database
or file, that the service utilizes, or you can create various 'talking'
methods, like named pipes, tcp/ip comms, etc, that allows the
controlling program to directly talk to the service.

Subject: [dba-VB] A windows Service or Not a service?

I wrote a simple application that has a form and two buttons (along with
a
timer).  My initial idea was that I would write this to be a windows
service
so it would auto-start whenever a specific server would reboot etc.  The
purpose is that I need to get new records created by a "Vendor"
application
and have them sent to a Second "Vendor" system.  I call a custom view
that I
wrote that collects that last set of changes, then record by record
calls a
webservice on our SAP system and pushes in the new changes.  My sql
server
version is Sql Server 2000 so it's not as easy as just writing a soap
object
to make the webservice call, I think it was much easier to just write
the
app in c# and make the call that way, which works.  NOW for the tricky
part.  I wanted to write up the app to create a windows service
installer so
that my admins could log into the windows server and either start or
stop
the application, I also wanted to provide a gui view to the windows
service
so that they could choose a different timer so it could run every 1
minute
(every 2 minutes, etc..) what ever they would choose.

after reading MS's description on windows service classes, I noticed
that
supposedly the .Net Studio does not support this, but I've seen other
apps
that DO provide a gui view to the windows service that they introduce.
so
my question to the group is, have you done this before? and if so how
did
you go about it?

The Windows service classes supported by the .NET Framework do not
support
interaction with interactive stations, that is, the logged-on user. The
.NET
Framework also does not include classes that represent stations and
desktops. If your Windows service must interact with other stations, you
will need to access the unmanaged Windows API. For more information, see
Window
Stations<http://msdn.microsoft.com/en-us/library/ms687096%28v=VS.90%29.a

Desktops<http://msdn.microsoft.com/en-us/library/ms682573%28v=VS.90%29.a

the Platform SDK documentation.

Nope, too much money for me.

If they would do it for $199 I would have it on order already.
