Not reponsive form

[Albert Chua via .NET 247]

I am developing a client/server application using VB.NET inVS.NET 2002. The client application have a form (Form A) thatquery the server application via Winsock and once Form Areceived the server's response (DataIn event) it launch Form Band hide Form A. The problem that I am having is that Form B isnot responsive after it's launched. What is the problem? Pleasehelp?

I tried launching Form B using a button in Form A and it worksperfectly. But Form B is not responsive when it's launched to inthe DataIn event, it's not responsive at all. Please help.

Hi Albert,

This is probably because Form B is being launched on another thread. If so,
you'll need to add a method to Form A that launches Form B and then use
BeginInvoke from the Datain event handler. It would look something like
this:

In Form A

Public Sub ShowFormB()
Me.Hide
Dim fb as New FormB()
fb.Show()
End Sub

In Datain event handler

Me.BeginInvoke(New MethodInvoker(AddressOf Me.ShowFormB)

Hope this helps,
