[IronPython] Best way to stop script execution?

[Jimmy Schementi]

When running in a non-UI thread in Silverlight, you can dispatch back to the UI thread for UI interaction. Every UIElement has a "Dispatcher" property, so you just need to grab that and call BeginInvoke, passing a delegate.

// In some background thread
Application.Current.RootVisual.Dispatcher.BeginInvoke(delegate() {
  HtmlPage.Document.GetElementById("foo").SetProperty("innerHTML", "hi!")
});

What about if we need access to the HTML DOM (It's a silverlight application) from that thread? During execution of scripts there might be printouts to the DOM. But how can we do that without illegal cross-threading?

Thanks for the reply.

No, we haven't placed the script execution in their own thread. I guess the best way must be just to place the exec command in that thread. I'll check out Thread.Abort.

Are the user scripts already running in a thread of their own? If they are you can abort the thread (with all the consequences that brings) using Thread.Abort.

Thanks for help!
