Why is sometimes WebBrowser.Dispose() launching Internet Explorer?

Question

When I do the following (Actually I repeat the same whole code with different web pages):

        Navigator nav;
        nav = new Navigator();
        nav.B         


        

Answer 1

I had the same problem when I tried to invoke Dispose() function of a WebBrowser in a ThreadPool Queued executing.

I started a Timer in the delegated of Control.Invoke to resolve it. This is my code:

    public delegate void SucceedDelegate();
    // calling by ThreadPool.QueueUserWorkItem(succeed);
    protected void succeed(Object obj){
        Application.OpenForms[0].Invoke(new SucceedDelegate(succeed0));
    }
    private void succeed0()
    {
        Timer timer = new Timer();
        timer.Interval = 1;
        timer.Tick += succeedHandler;
        timer.Start();
    }
    private void succeedHandler(object sender, EventArgs e)
    {
        ((Timer)sender).Stop();
        succeed00();
    }
    private void succeed00()
    {
        //call WebBrowser.Dispose() here
    }

It's ugly, but working well.
