I don't want to stop the user from accessing anything else in Windows, but only one application(other than the one I am running). What I want to do is force the user to type something in the InputBox before they can continue working. Is there any way of doing that?

If not, is there a form's method that is called when a form is brough back to the top. I though Activate would work, but it does. I also tried Show, Paint, and Refresh.
