wpf method to start the application message loop

Question

Hi All,

I need to create a Form in a different thread and keep it ranning until a user performe some action in the main thread (click a button).

It is not very difficult to do using

System.Windows.Forms.Application.Run(new ApplicationContext());

that starts an application message loop in the current thread. But this solution requires the usage of System.Windows.Forms namespace, which in not a wpf namespace.

Do you know a wpf-way of achieving this goal? =)

P.S. without starting an application message loop the thread will be imidiatly terminated after processing of the last expression in it. So, the Form will appear only for a moment and will be closed. =(

Answer 1

Use System.Windows.Threading.Dispatcher.Run()

Answer 2

Does this help ?

Answer 3

And, there's also Dispatcher.PushFrame

This is handy because it allows you to run the messageloop until a stop criterion you define, for instance while a progress dialog is on the screen.
