Question

We have a SmartClient built in C# that stubornly remains open when the PC its running on is being restarted. This halts the restart process unless the user first closes the SmartClient or there is some other manual intervention.

This is causing problems when the infrastructure team remotely installs new software that requires a machine reboot.

Any ideas for getting the SmartClient app to recognize the shutdown/restart event from Windows and gracefully kill itself?

UPDATE: This is a highly threaded application with multiple gui threads. yes, multiple gui threads. Its really a consolidation of many project that in and of themselves could be standalone applications – all of which are launched and managed from a single exe that centralizes those management methods and keeps track of those threads. I don’t believe using background threads is an option.

OK, if you have access to the app, you can handle the SessionEnded event.

... Microsoft.Win32.SystemEvents.SessionEnded +=new   Microsoft.Win32.SessionEndedEventHandler(shutdownHandler);  ...  private void shutdownHandler(object sender, Microsoft.Win32.SessionEndedEventArgs e) {   // Do stuff }
