Cam,

Can it be that you have inserted somewhere End instead of completely End If
or something?

It sounds like this.

Hello,
>
I am using Visual Basic.Net 2008 I have created about 3 forms working OK
in the past, but now I doesn't work anymore. When I try to start to
run/debugging the program it starts to open the form in a second and close
quickly. I don't know why this is happening. I add a treeview control,
but I don't think that is the problem. I just don't know what I did. Any
tips will be appreciated. Thank you in advance.

Cheers.

I recommend you to check your startup form's load event. There might
be some code that closes your form because of conditional statements,
or another program on your system may be killing your application.

Plus you can use a technique to catch close reason by putting in your
FormClosing event as follows:

Private Sub Form1_FormClosi ng(ByVal sender As Object, _
ByVal e As System.Windows. Forms.FormClosi ngEventArgs) _
Handles Me.FormClosing

' See close reason on exit
Msgbox(e.CloseR eason.ToString)

End Sub

Hope this helps,

Onur G.

Don't forget that you can start the debugger using Step Into (F8). That
enables you to trace the execution from the very first command, before the
form is shown.
