lock screen:i need a java source program that when i try execute it.........

Question

i need a java source program that when i try execute it.it lock my windos desktop screen and i can't click any icon.and just can move mouse.

Answer 1

I don't know if there's a Java function for it, but the Windows shell command is:

rundll32 user32.dll,LockWorkStation

That's a period, then a comma -- no spaces in the second part. Maybe someone can point out how to do a subprocess.
