Problems with ExitWindowsEx

Hi.
I am trying to shut down my comp. (or turn off power) with if but I fail. Log off does work, to bad Power off doesn't . So can anyone help me with this problem?

Code:

This DOES work:

    if ( Attempts <= 1 ){
    ExitWindowsEx(EWX_LOGOFF,0);
    } 

This DOESN'T work:

    if ( Attempts <= 1 ){
    ExitWindowsEx(EWX_POWEROFF,0);
    }

Off Topic: Sorry for the first post but why can't I post on a old thread?

>>> why can't I post on a old thread?

You did read the rules before posting didn't you? Let me help, Rule 5...

Ow ok, I am sorry now I know the rules but I still don't know my problem. Just need to wait some longer, thanks anyway.

As mentioned in the other thread, you need to enable the SE_SHUTDOWN_NAME privilege. You can do this with my EnableProcessPrivilege function:

Code:

EnableProcessPrivilege(SE_SHUTDOWN_NAME, TRUE);
