Hi i have coded a program that can lock the computer (WIN98). i Use it in school but as you can understand some people doesn't care about my locker program and just restart the computer so i wonder if anyone knows how to turn off the shutdown button in Windows 98. My School use NetWare Novell as login client. The computer restore it self with a Security card so it will be the same every time i turn on the computer. Is there anyway to turn the security Card off ?? or make Novell Help me ???[/quote]

No non-server class computer has it, I think. There is no protection against restarts even on NT machines, because you can always hit the power/restart button -OR- plug out the power-cord.

Then you can log in with your own account.

I can suggest you maybe look at the shutdown API and catch that behaviour. Maybe then you can intervene and stop the shutdown process. I haven't got any other good ideas

maybe somehow block/remove executing system32\shutdown.exe?

There is an API function for that, AbortSystemShutdown. However keeping pressed the shutdown button for 3 seconds on an ATX computer is enough to turn it off.

you can also make your locker write itself to Run in registry, so it will run anyway. This could keep off less experienced guys

I Can not run AbortSystemShutdown and use system32\shutdown.exe? becouse it is a 9x System. and i cna not do anything to the registry becouse it will restore when the computer is restared

what about patching ExitWindows in user32.dll?

vasilev: probably not a good idea, it's a school computer

Why not:



I have used this in the past.
