See my earlier post for a brief description of what’s going on and note the following:
- The main class of interest is CjcWebBrowser. It starts a worker thread to take snapshots of the browser control and updates the WriteableBitmap through Dispatcher.Invoke.
- There’s some obsolete code in there (mainly in the NativeMethods folder). It could use some refactoring 🙂
- It’s tempting to revert to using the Windows Forms WebBrowser control (instead of the WPF/3.5 one). It already has a ‘DownloadProgress’ event and seemed to perform a bit better (but I could be wrong on that). Let me know if you get chance to try it…
