Dear ALL,
I'm trying to lock the Desktop from being accessed by the user unless he enter the correct Username and passswod ....

i managed to lock the desktop from being accessed by mouse ...
but the problem is that he still can use the sys. keys (as CTRL , ALT + TAB , Windows key....etc) in which i want to disable .. so only he can type letters and numbers ..... any suggestion will make me very greatful...

Thanx in advance
