The Windows message to applications for shutdown is WM_close or
WM_ENDSESSION.
Hence I would interrogate for this message in the formclosequery proc of
your
program, and carry out the necessary actions according to the state of
WM_close.
Try the code out below and put a break on the wm_close line to see if the
message returns true (Im not sure)
move your cursor over both wm_xxxx on break to see the state of both
messages.
For example:
procedure TForm1.FormCloseQuery(Sender: TObject; var CanClose: Boolean);
begin
// Ask user if shutdown should occur.
if (wm_close or WM_ENDSESSION) and (MessageDlg('Are you sure?',
mtConfirmation, mbYesNoCancel, 0) = mrYes)
then CanClose := true // Allow Windows to shut down.
else CanClose := false; // Prevent Windows from shutting down.
end;
