Hi,
I have succeed added my tabstrip with the codes below :
For Each DR In DS.Tables("Webform").Rows
Dim t As New Tab

I have a discretized simulation model, that has a heirarchical structure.
1 Top level class
   M second level classes stored in top level class
       N third level classes, stores in each second level class.

Moving to .NET from former VB6 and Java background.  One thing I don't
understand is why class members are not-overridable by default.  The
class author has to specifically say that a member is
virtual/overridable in order to allow another author to extend that

I'd like to get some feedback on preferred practices for indexes on
databases, and their use outside the database.
The situation I am trying to address is this.  I have a set of XML documents
that I want to have hold collections of indexes that will be used to make

Does anyone else agree with me that the WebRequest object SHOULD NOT throw
an exception when the web server returns a status code of 500? I mean, 500
is a valid response and should be expected by the caller. The
HttpWebResponse object already has a StatusProperty, why can it ...

SP1 client scripting appears to have some problems.  The VALIDATION controls
will validate a form but not perform a postback after validation.
Only solution is to uninstall the SP and reinstall the framework without the
SP.

I get the following message as soon as I copy all the project's files on the
network and try to run it from there: (Even Build don't give me an error)

I'm trying to test MSMQ on windows 2003 but I keep on getting
"System.Messaging.MessageQueueException: Queue is not registered in the DS",
when I try to create the queue.
I have windows 2003 installed in workgroup mode.

I've ran into the issue that while sending a MailMessage with
MailAttachments, an exception is thrown because of network issues.  It
appears that the attachment file is still locked (documentation does state
that during the email xfer, the file is locked).  I can't see a way to

I am attempting to use APIs via vb.net to view and ultimately modify
file permissions. I made it part way and got stuck. I am able to use
GetExplicitEntriesFromAcl and get the number of ACEs, but I can not
find a way to get at the individual ACEs in the returned array.

When I do a windows update I noticed that the Net Framework 1.1 SP1 is
available.  The question I have is, does that mean that there is a SP
available somewhere for Visual Studio.NET 2003?
I would think that a SP for both would be required if there are changes to

The application I am developing needs to update/delete records from an
Oracle 8i database once a day. Together, the tables have more than 500.000
records.
At this moment, I am using an Oracle job to do the work but I am considering

Microsoft is teasing developers with some beta technologies, like
.NET Framework 2.0 and Visual Studio 2005, which are currently in beta1
development cycle
SQL Server 2005 Express which is in beta2, and I did notice that beta3 will

I was hoping someone might be able to shed some light on this bizarre
behaviour.
I have observed some strange behaviour with System.IO.FIle.Move where it
seems to be copying a file as opposed to actually moving it. The following is
