Shutting the system down

[Baal80]

Hello!

I have a following problem - I want to shut the system down from within my application. I'm using the following code:

[first, if Windows version is WinXP or Win2000 or Win2003 I set the necessary privilege (SE_SHUTDOWN_NAME) - this WORKS, I'm sure about this part]

and then:

unsingned long a;
ExitWindowsEx(EWX_POWEROFF+EWX_FORCEIFHUNG,a);

Everything works fine on XP, 2000 and 2003. But:
- on Windows98SE the system just logs off and waits for the user to log on,
- on Windows NT4.0 with SP5 the system RESTARTS (doesn't shut down).

Can you tell me what am I doing wrong?
Or maybe these systems just don't support the "power-off feature" as described in Builder's Help?

Thanks in advance guys for your help.

Unfortunately yes. I have the necessary privileges. This behaviour is strange to me. I managed to use another function to shutdown Win98SE (my app determines the Windows version) - "RUNDLL.EXE user.exe,exitwindows" - called by ShellExecute. Well, shutting down NT still causes a problem

I don't know if these sites will help or not. Here is some source code for Delphi:

If you want a third party program that your program can call, you can use:

Finally, there is documentation for Native API (a hidden API) at:

Well... I found a *very* interesting site

http://www.robvanderwoude.com/shutdown.html

- I reprogrammed functions to behave differently depending on the OS version (95/98+Me/2k+XP, NT is not supported) and the only thing I want to do know is to check if that works... As I have XP system, XP shutdown works fine for me, but what about 95/98/Me/2000... Does anybody have these systems nowadays?

Does anybody have these systems nowadays?"

you seem to think everybody ran off the cliff like good little lemurs following microsoft and XP.
