Open only once

How do I stop the user from opening my app more than once?

when it exits, shell to another app that deletes it. Why do you want to do this?

VB Code:

Private Sub Form_Load()
If App.PrevInstance = True Then Unload Me
End Sub

Oh, I thought he meant only run it once and never again. Sorry. Ignore my last post.

thanks doods! :D
