I am using Visual Studio 2003 to develop a windows application in which I
allow the users to just press Enter, while the focus is on a textbox, in
order to perform a search. My problem is that sometimes Keypress event
stops being raised. I have found that I can reproduce this behavior by
performing a search, opening up another form, then trying to perform another
search. The second search will NEVER work.
How can I fix this problem?
Thanks,

I think we will need some simplified code that demonstrates the problem to
help you out.

Does the second form you're bringing up have a button that is the form's
default? That might be stealing your keypress event so it's never raised.

When you say opening up another form, do you mean another instance of
the same form?

I think Brian's hit the nail on the head.
Hi
I agree with Brian's suggestion.
Also I can not reproduce the problem with the code below.
Private Sub customerNumberS earch(ByVal sender As Object, ByVal e As
System.Windows. Forms.KeyPressE ventArgs) Handles txtCustomerNumb er.KeyPress
If e.KeyChar = Chr(13) Then
dim fm as new form
fm.show
End If
End Sub
You may have a try and it is better to provide a reproduce sample.
Thanks.

Todd,
When you test this, than it is maybe easier when you want to emulate
situoations which takes a time to try just routines as
Private Sub customerNumberS earch(ByVal sender As Object, ByVal e As
System.Windows. Forms.KeyPressE ventArgs) Handles txtCustomerNumb er.KeyPress
If e.KeyChar = Chr(13) Then
threading.threa d.sleep(7000)
End If
End Sub
That gives you in my opinion more the change to isolate your problem.
Just as idea

No, just opening up another form in my project.
At this point, I have been trying to use a process of elimination to
determine what is causing the problem. I have been removing steps from the
process and trying to determine which step causes the functionality to
break. Right now it seems to have something to do with the fact that when I
return to my 'main' form and change my search criteria and press the Enter
key it is trying to do the button-click that opened up the second form
instead of my search. Any ideas on how I can prevent this action?
