I got this error:

System.InvalidCastException was unhandled by user code

This error I get with that:

 while (webBrowser1.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents();

I dont know why I get that error, on the other applications this has worked.


Here is the complete function:

private void timer1_Tick(object sender, EventArgs e)

If I call

MessageBox.Show(webBrowser1.IsBusy.ToString()) I got the exception that user code was unhandled ......
and the same here MessageBox.Show(webBrowser1.ReadyState.ToString())

It seems like that webbrowser1 doesnt works at all???
Maybe I forgot something ???

Please I realy need help, I'm stucked here for 4 days .....
