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
