Take control of the screen

Hi Guys,

Please I writing a program that puts a shield on computers runinng in a public place. I need this program to bar access to the screen until users enter valid codes to unshield the systems and let them use these computers. The program is running well except that when people start playing certain games that invoke certain screen modes, the shield becomes ineffective, and can't bar them from using the computers.

Please using VB, how can I make my shield have priority of all screen modes.

Thank you

I'm not sure what type of window you want, but if it's one that can be made as "System Modal", then the user WILL HAVE to use that window.

Thanks,

When a game is launched, it could directly call up screen drivers, and run in a screen mode seperate from the normal windows desktop.

What I need is a way of restoring the screen back to the normal windows desktop so that my program can take control from there.

For example, when a game launches in such a mode that bypasses the normal windows desktop, if you press the windows key on the keyboard, it brings up the start menu, and overrides the game.

Thanks
