When I create a thread in my VS .NET application (Dim trdSocket As Thread = New Thread(AddressOf Socket.Listen)), when I close the application with the X in the top right corner, my application still in the list of process... I guess I need to kill the thread when I exit the program ? Which event do I need to use and with which method of the Thread class I can kill the thread ?
Thanx a lot!

trdSocket.Abort <br />
End<br />
End Sub<br />

Is there anyway we can design crystal report at VB.NET runtime? I've been doing research about it but couldn't find anyone doing it.
If you know a website where I can buy it, please help. Thanks

it is possible, but is neither easy, nor cheap.
do research on the RDC tool within Crystal. I worked with a group of people who had a .net web app create reports, with both data and formatting done on the fly. No rpt file was ever created on the server. However, with crystal, licensing will bite you in the ass. If you expect to have more than 50 concurrent connections, expect to spend well over $100,000
I should also say that it has been 1.5 years since i've done anything with crystal, and some of what i just said may have changed. I believe we were using 8.5 or crystal 9 at the time.
Have you looked into using Reporting Services[^] from Microsoft? I would suggest using RS over Crystal any day. Only misleading thing about RS is that if you have your web server on one box, and sql on another (as you should), you will need 2 SQL server licenses. SQL Standard is fine if you are fine with windows auth for security, otherwise, you will need at least one of the licenses to be Enterprise.
hope this helps more than it confuses

 I am trying to work out client server application using VB .NET Remoting. MY APPLICATION IS RUNNING AS FOLLOWS:
Server has a set of DLL's to be loaded via reflection from the client.There is also a host application running on server that
returns the reference of an anchored(Not Serializable) object to the client(listening at some port on server machine for
client requests). This Host application is invoked remotely by the client.When i invoke this host application directly from
some DLL (ON CLIENT) & CALL ITS METHODS, it works fine. However when i load some assembly via reflection on the client
(dynamic loading) & that dynamically loaded assembly in turn try to call some method on that object (returned from remote
Host on server) then a SECURITY EXCEPTION IS RAISED.This Security exception is only raised for those methods that accesses
the database on the server & not for any other Methods. I am unable to find a solution to this problem.
CAN ANYBODY HELP ME ?

I like using frames. VB.NET does not (or so it appears). I have a header frame with a navigation sub (Nav) that changes a title grapher (in the header frame) and the URL of the main frame. This works fine when I call it from the header frame, but when in import the header class and call it from the menu frame, it crashes because the focus is on the menu frame and not the header frame. I have tried:
With ("javascript:parent.frames('header').document.items('Image2')) but this does not work. Is this really this hard to do? Here is my subroutine I am trying to use from both the header frame and the menu frame:
Public Sub Nav(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs)
Dim strName As String = e.CommandName
Dim strArg As Integer = CInt(e.CommandArgument)
Dim strURL As String
Select Case strArg
Case 1
Me.Image2.ImageUrl = "images/Page1.png"
Me.Image2.AlternateText = "Welcome"
Case 2
Me.Image2.ImageUrl = "images/Page2.png"
Me.Image2.AlternateText = "About Us"
Case 3
Image2.ImageUrl = "images/Page3.png"
Image2.AlternateText = "Mission"
Case 4
Image2.ImageUrl = "images/Page4.png"
Image2.AlternateText = "Gallery"
Case 5
Image2.ImageUrl = "images/Page5.png"
Image2.AlternateText = "Services"
Case 6
Image2.ImageUrl = "images/Page6.png"
Image2.AlternateText = "References"
Case 7
Image2.ImageUrl = "images/Page7.png"
Image2.AlternateText = "Contact Us"
Case 8
Image2.ImageUrl = "images/Page8.png"
Image2.AlternateText = "Favorites"
End Select
'Response.Redirect(strURL)
End Sub

Your question would be better handled in the ASP.NET Forum. It has nothign to do with VB.NET, even though the code is written in it.
BTW: VB.NET/ASP.NET does work perfectly fine with frames, if done correctly.

Hi all,
Here's my problem. I have an MDI but I don't want the user to be able to open more than one instance of a form at a time. I have written the following function. I think I am close but this still allows more than one instance open at one time or in other words allways returns False:
Private Function checkExistingForm(ByVal frm As Form) As Boolean
checkExistingForm = False
Dim frmArray() As Form
frmArray = Me.MdiChildren()
Dim frmArrayLength As Integer
frmArrayLength = frmArray.Length
Dim i As Integer
For i = 0 To frmArrayLength - 1
If frmArray(i) Is frm Then
Debug.WriteLine(frmArray(i))
checkExistingForm = True
Exit For
End If
Next
End Function
I call the above function in this code:
Private Sub ToolBar1_ButtonClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ToolBarButtonClickEventArgs) Handles ToolBar1.ButtonClick
If e.Button Is Me.tbStock Then
Dim stockForm As New Stock
If Me.checkExistingForm(stockForm) = True Then
Exit Sub
End If
stockForm.MdiParent = Me
stockForm.Show()
End If
end sub
Any help would be greatly appreciated.

Hi ,
Check out this one..........................
Private Function IsFormOpen(ByVal OpenForm As Form) As Boolean
Dim intOpenForms As Integer
Try
Dim formExists As Boolean = False
For intOpenForms = 0 To MdiChildren.Length - 1
If MdiChildren(intOpenForms).Name = OpenForm.Name Then
formExists = True
MdiChildren(intOpenForms).Activate()
Exit For
End If
Next
Return formExists
Catch exc As Exception
Throw exc
End Try
End Function
Private Sub ToolBar1_Buttonclick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ToolBarButtonclickEventArgs) Handles ToolBar1.Buttonclick
If e.Button Is Me.tbStock Then
Dim stockForm As New Stock
If IsFormOpen(stockForm) = True Then
stockForm.Dispose()
Exit Sub
End If
stockForm.MdiParent = Me
stockForm.Show()
End If
end sub

Not without seeing your code, what your trying to print, and how your trying to print it. Are you trying to print straight Text or are you trying to print the contents of a RichTextBox, graphic image, what?
Since your using a dot matrix printer, your going to find a very small base of developers who still use one for any purpose, and hence, a small pool of developers who can help you with this.

good afternoon.
i'm currently using vb.net and sql server.
i just want to ask advice or guidance on how to save microsoft office documents(.doc,.xls,.vsd,.ppt), text files, and html documents, etc. in the database and if i open one of the files, example is a word document, the document will open in the same format as in the ms word.
what appropriate tools should i use? i'm thinking of the saving pictures in blob format but i don't if it is applicable...
thanks in advance...

Hi,
If u r thinking to save Files in dB than better u set Column's datatype as image........
u can easily convert the file into array of bytes as
Dim reader As New FileStream(strFileName, FileAccess.ReadWrite)
ReDim pi_arrbyteFiles(reader.Length - 1)
reader.Read(pi_arrbyteFiles, 0, pi_arrbyteFiles.Length)
reader.Close()
When u want so save the file back on the m/c u can call
Dim strWrites As FileStream
If File.Exists(strFileName) Then
File.Delete(sfdFile.FileName)
End If
strWrites = File.Create(strFileName)
strWrites.Write(pi_arrbyteFiles, 0, arrbyteFiles.Length - 1)
strWrites.Close()
End If
Regards,
Ritesh
