How can I access the ui thread in an asynchronous httpwebrequest callback in a bho

I'm struggling to get access to the ui thread in an asynchronous httpwebreques开发者_如何学Pythont callback in a browser helper object. The current document and windows don't reflect those witnessed on the calling thread, so I can't update the UI as required.

Can anyone help?

Cheers

I'm not certain what context you're in, but in WinForms, you can access the main Form's UI thread from another thread with form.Invoke() like this:

        // Assuming the following Form and method:
        Form form = ...
        Action method = ...

        // Invoke the method like this, so it is run in the UI thread.
        if (form.InvokeRequired)
        {
            form.Invoke(method);
        }
        // If we are already in the UI thread, 
        // just run the method without an invoke.
        else 
        {
            method();
        }
