Windows broadcasts a message (WM_QUERYENDSESSION) to all top-level windows when a shutdown begins. ExitWindowsEx() initiates the shutdown. Because the message is broadcast using SendMessage(), you can suspend the shutdown process until the user finishes interacting with your application by manually pumping window messages. When the user is done, exit the manual message pump and return TRUE to the caller to let the shutdown continue. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 VerifyMyPC v1.0: "A stable PC is a happy PC."
