hvordan fungerer den??

ret& = ExitWindowsEx(EWX_FORCE Or EWX_SHUTDOWN, 1)

sådan??

Ovenstående fungerer med Windows 95, 98 og ME. På NT baserede systemer som Win2000 og XP skal din proces have de rette privilegier for at lukke systemet. Så derfor kan du bruge flg. i et modul i stedet:

Du kalder så ShutDownSystem med de samme flag som før:
    EWX_LOGOFF = 0
    EWX_SHUTDOWN = 1&
    EWX_REBOOT = 2&
    EWX_FORCE = 4&
    EWX_POWEROFF = 8&
    EWX_FORCEIFHUNG = 10& ' kun NT5
Bemærk at EWX_POWEROFF er den parameter der lukker computeren og slukker for strømmen.

Et GÆT:

msgbox "Nu lukker diin PC"
Shell "shutdown -s"

msgbox "Nu genstarter din PC"
Shell "shutdown -r"

Ved ikke om det virker, men gør det, er det ret simpelt :o)

martin_moth din "version" virkede :) jeg tror jeg tager den, det er den nemmeste.. Tak for svar alle sammen!!

Hvordan du vil håndterer kørende programmer, når du så brutalt lukker PC'en, ved jeg ikke. Men det har du sikkert tænkt på

Hermed et svar :o)

Det er ikk noget særligt stort program jeg bruger :) men har da en måde... Først sætter jeg den til at lukke computeren... men en shutdown -s -t 10 så venter den jo 10 sek med at lukke ned, så kan jeg oz nå at lukke programmet :)
