Is there any way to get the gui thread dispatcher when you have no reference to any elements..

A:
Use the Dispatcher.CurrentDispatcher property.
Note that you need to get it from the UI thread.

You can use that static property without any references to UI objects, as long as you're on the UI _thread_.

If you're not sure, you probably are. (Are you using the `Thread` or `ThreadPool` classes?

Is your code running there?
SLaks

yes its running on a separate thread but not when the tread is started?

Then you'll need to get `CurrentDispatcher` in the UI thread and pass it to the other thread.

A:
You can grab the UI Dispatcher from the static application instance: Application.Current.Dispatcher
You may want to check Application.Current for null first, as it can be cleared during a shutdown sequence.
