TabControl problem...please help. :(

[clifgriffin]

Okay...this is driving me crazy. I have a text box named txtDisplay in a Tab Control named TabControl1 on page 2 named Tab2.

How do I reference it correctly from the code???

I keep getting a "Index and length must refer to a location within the string." error.

This is the code I'm currently using..


Private Sub DisplayText(ByVal t As String)
txtDisplay.AppendText(t)
End Sub


If I move the text box off of the tab control it works...

How do I properly reference the text box??

Thanks in advance!

That works fine for me, maybe its something else. How are you adding the textbox to the tabpage? I assume just drag and drop. Wierd.

[clifgriffin]

Yes...drag and drop.

I'm using the Microsoft example of using chat in with tcp sockets. Works like a charm if I drag it off the tab page...broke when I drag it back on.

Thanks for the reply.

If anyone can help me...I need it!

Thanks,
Clif

Maybe it just removed the Handles blah blah event info for any events you were using. Sometimes the IDE does that if you move or cut and paste controls. So if the error message doesn't directly relate to the control then maybe it is a logic error caused by event code not firing.

It compiles fine...upon execution it throws this message though...

Does this change your diagnosis...and what would I do to restore the handles?

Thanks!

Check either of these lines:
Klip.Form1.DisplayText(String t) in C:\Documents and Settings\Clifton Griffin\My Documents\Visual Studio Projects\Klip\Form1.vb:line 423

Klip.Form1.Form1_Load(Object sender, EventArgs e) in C:\Documents and Settings\Clifton Griffin\My Documents\Visual Studio Projects\Klip\Form1.vb:line 368

The Handles bit may be nothing, it really depends on what the code is suppose to do. It seems like the textbox is suppose to have text in it and doesn't or if the length of the text is wrong or something.
