I'm new to Vs8 and need a program.

I designed program called 'lock out' years ago in VB6 to keep my oldest son of the PC until a certain time in the afternoon.

I need a similar program to get my second son off the PC at 10 or 11 pm and stay off til morning.

Needs to interrupt anything at a set time and stay on top with the task menu disabled.

Has anybody made or seen something like this?
