Q: Shutdown WindowsAnswerCall the ExitWindowsEx API function. void __fastcall TForm1::Button1Click(TObject *Sender) { ExitWindowsEx(EWX_SHUTDOWN, 0); } Note: The second argument to ExitWindowsEx is ignored by the OS. The first argument controls how the function behaves. The possible values are listed below. You can combine commands using a bitwise OR. EWX_FORCE Forces programs to close without sending WM_QUERYENDSESSION and WM_ENDSESSION messages to notify them that Windows is shutting down. With any of the other flags, programs have the power to abort the shut down. EWX_LOGOFF Closes all programs and then logs the user off. EWX_POWEROFF Powers down the computer if it supports it. EWX_REBOOT Reboots the machine. EWX_SHUTDOWN Shuts the machine off without restarting it. Note: The ExitWindowsEx function starts the shut down process and then returns to the calling function. The shut down completes sometime after the function returns. If you don't specify the EWX_FORCE flag, Windows will send messages to each running program to ask permision to complete the shutdown. Note: ExitWindowsEX returns TRUE on success and FALSE if an error occurred. Note: EWX_LOGOFF has some problems on Windows 95. For more details, consult Microsoft knowledge base article Q149690. Note: On Windows NT, you must ensure that your program has the proper security rights to shutdown the system before you call ExitWindowsEx. Your program must have the SE_SHUTDOWN_NAME privilege. | ||||||
