LOCK OS

[Fei]

Hi,

Is here a way to Lock OS ? Suppose I write an application. However, I
don't want user to use Alt-Tab or any key such as Win key to do anything
else. The user has to shut down application first. Then he/she can use OS as
usual.

Any suggestions/ideas/links would be great to me. Thanks !

I've tried doing this to no avail. The OS message queue, which is at a
higher priority than the application queue, traps Windows shortcut keys and
processes them before allowing an application to process its messages (this
is why Ctrl+Alt_Delete works so well).

I used a Windows Journey Hook to trap keystrokes and failed to see any
Windows shortcut keys on examination of the trace. All my input (keyboard
and mouse) was captured perfect with the exception of Windows shortcut keys.

Any additional info from anybody else who might have achieved this would be
fantastic.
