Happens when the user, or some program, requests the operating system (and your program) to shut down.


Args

ARG(1) is 0 if the user clicked the Logoff or Shutdown button in the Shut Down Windows dialog box. ARG(1) is nonzero if the user clicked the End Task button in the Task List dialog box.


Return

An empty string to prevent shutdown, or 0 to allow it.


Notes

If you allow shutdown, then an ENDSESSION event will happen.

If you do not handle this event, then the operating system will assume that your script intends to allow the shutdown.
