shutdown wpf while messagebox open

Question

I try to automatically shut down an wpf application at midnight with:

Dispatcher.BeginInvokeShutdown(DispatcherPriority.Normal);

This works very well in general, but when there is a message box opening waiting for user response, the application fails to shutdown. Is there a way to shut down the application regardless of the opening messagebox?

Answer 1

For WPF Applications use

Application.Current.Shutdown();

Answer 2

Maybe you can use Environment.Exit (immediately exits...very naughty to do on a GUI app) or find the MessageBox window and send them a close message, or hook the creation of any native MessageBox Dialogs (...i.e. track the Window handle, so you can then close them).

• Close C# Console Application after MessageBox click

• Force to close MessageBox programmatically

• Closing Applications

• Right way to close WPF GUI application: GetCurrentProcess().Kill(), Environment.Exit(0) or this.Shutdown()

And a very very naughty way:

Process.GetCurrentProcess().Kill()
