computer 1 (Mom)
copmuter 2 (son's pc)
using coputer 1, i want to lock and unlock the screen of computer 2 whenever i wanted..
i need a code to lock and unlock screen.
-unable to use alt+tab or close program ..
-unable to do anything

please just a simple code will do .
(for my assignment please help .. )

Is this in relation to your research lab program question?

We can't give code to do this type of stuff.

For this specific scenario, I assume both computers are on the same network and mom owns the PC's. Get Mom to remote desktop into sons computer then she has control whenever she wants to.
