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- Very Happy 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 Sad

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

Why not:

Quote:
The WM_QUERYENDSESSION message is sent when the user chooses to end the Windows session or when an application calls the ExitWindows function. If any application returns zero, the Windows session is not ended.


I have used this in the past.
