> I think you didn’t get me correctly. My intention is not to beat the
security of Windows NT. I don’t want to show a fake dialog box during a
CTRL+ALT+DEL key combination. Instead when my application is running, for
some action by the user I need to pass control onto the “Windows NT
Security” dialog box which pops up when you press the CTRL+ALT+DEL key
combination. I think I made myself clear.
What you want is a part of the security subsystem. NT has been designed
to prevent what you want. It is off limits. It might not be totally
impossible but it’s probably close enough to unpractical. One way I can
think of would be a programmable device hooked up to the keyboard and
mouse.
