Just to update you on how my web page thumbnails generator (described in my post my WebBrowser experiment ) goes on...

Since this is used on a server, it , as expected, crashed a couple of times per load test... that's not very useful... I brought a little modification to it...  and it didn't crashed since then.... (note that this is not on production servers)

So the first thing I do is that I load the web page using HttpWebRequest and get its stream from HttpWebResponse.GetResponseStream. Once I get the stream I create a new WebBrowser but instead of opening the page from a URL (with WebBrowser.Navigate), I load the stream that I got from HttpWebResponse into my  WebBrowser's DocumentStream property. And that's it! the rest is the same as before! It's even nicer since I just get the WebBrowser.DocumentCompleted  called once... I don't need to look at the URL to see if it's my main page or an embedded Flash stream... and no more about:blank called after it is completed.

So here is my new method that I have added to my ScreenCapturerSTA class:

private void CaptureMS(object obj)

{

    m_byteImg = null;

    MemoryStream ms = obj as MemoryStream;

    try

    {

        using (WebBrowser webBrowser = new WebBrowser())

        {

            webBrowser.DocumentCompleted += 

                new WebBrowserDocumentCompletedEventHandler(webBrowser_DocumentCompleted);

            webBrowser.Height = 1000;

            webBrowser.Width = 1000;

            webBrowser.ScriptErrorsSuppressed = true;

            webBrowser.ScrollBarsEnabled = false;

            webBrowser.DocumentStream = ms;

            while (!m_done)

            {

                Application.DoEvents();

            }

        }

    }

    catch (Exception ex)

    {

        Trace.WriteLine(ex.ToString());

    }

}

So, just a coincidence? I mean, the WebBrowser still has to load the content...  at least it seems more stable now... 

Next step? hmmm, I'm tempted by a MONO/GECKO experiment...  I might give it a try...
