>I have put some code in a valid event, which if not valid produces a messagebox that informs the user of the problem. However, I can't seem to avoid the wait window that says 'invalid input'. Is there a way to disable this, or customize it? On another note, can someone tell me why I would need a VALID event versus using the LOSTFOCUS?

Just return 0 from the valid event instead of .F. This prevents the use rform leaving, but suppresses the VFP message.
