If you stop the clock, you'll probably need to use DOS. Explain what you mean.

If you want to prevent altering the time, use an external time source (like the web) and check it...

I am not aware of any way to lock the system clock. You can set the time, you can sync the time you can even do it in a timer if need be so any changes get set back to the proper time when the timer fires but locking it would seem to have little purpose so I doubt there is a method provided to do so.

Think about it. Remove battery, unplug, and unplug network card. You want PC to self-destruct?

Ahh, only problem is that would terminate the program

I think you can make windows rights so restrictive, users can't change the time anyway.

That's what a SERVER is for. Active Directory can run ONLY your app on the desktop when someone logs in. As soon as they QUIT the app, they're logged off. Microsoft called the demo JOE LOCK-OUT when Windows 2000 was new

You could always hide the clock. I'd do that, especially if you do not want users to be able to change the time while your app is running.
