How do you prevent a user from changing forms

I need to know how to lock a user on to a window form.

Example: User is on form A. He clicks a button and it opens form B. If he click on form A, form b would blink and windows would make a sound, and form b would still be in focus.

Just open form b with ShowDialog( ). This opens it as a modal form with the behavior you've described.

Thanks a ton. It works perfect.
