I'm trying to figure out how to disable ctrl-alt-delete. I tried this code:

On Error GoTo exitsub
AppActivate "Windows Task Manager"
thesendkeys = "%{F4}"
SendKeys (thesendkeys)
Exit Sub
exitsub:
Exit Sub

But it sometimes doesnt work. Does anyone know the name for the delete key...like WM_DELETE or something, because I was thinking of setting a hotkey that is ctrl-alt-delete, and when you pust it it sends keys to windows taskmanager "%{F4}". Anyways please help.
