To je to jel tako e sad na primer hocete da ugasite komp?!?!
Znaci kad uzmemo win32 devlopers reference tu nadjemo da ima ovo:
Citat:
BOOL ExitWindowsEx(
UINT uFlags, // shutdown operation
DWORD dwReserved // reserved
);
Komanda iz Delphi-ja: ExitWindowsEx(EWX_SHUTDOWN,i);
U quick infu import library mu je user32.lib herm...
Znaci kako ja sad ovo da izvedem na istu foru kao sto ovaj daje komandu da pokrene browser?!?!
