WebBrowser as VisualBrush ?

Question

HI first :

Hi I try to catch my 

LoadCompleted event and i can't success any suggestions ?

<Grid>

<WebBrowser x:Name="WebBrowserTest" Loaded="WebBrowser_Loaded"  

LoadCompleted="wb_LoadCompleted"

ClipToBounds="True" />

</Grid>

</UserControl>

 
Code behind :

private void WebBrowser_Loaded(object sender, RoutedEventArgs e)

{

WebBrowser wb = sender as WebBrowser;

// wb.LoadCompleted += new LoadCompletedEventHandler(wb_LoadCompleted);//something i try.

wb.Source = new Uri ( http://www.google.com, UriKind.RelativeOrAbsolute);

}

void wb_LoadCompleted(object sender, NavigationEventArgs e)

{

throw new NotImplementedException(); // also a break point //

}

The final use of the WebBrowser in as a resource.

and i can't find the way to use webbrowser as visualbrush ?

Thanks.

Answer 1

 A WebBrowser hosts an HWND. You can't use it as the source for a Visual Brush.

Tim,  that's not strictly true. You can use a windows forms web browser as the source of a visual in WPF.
although I suspect it would now be infinately easier using 3.51 than the nasty device context twiddling I did.
more details of the WinForms version is on my blog (its pretty old now and was a proof of concept - putting Virtual Earth on a WPF form) but that should be a lot easier now.

I was meaning to do the same with 3.51, but just don't have the time at the moment! :(

cheers

Hi Epsilone3,
    I've just tried a quick example project with a web browser control from 3.5sp1 and it doesn't seem to want to be uses as the source for a visual brush at all. No amount of fiddling calling refresh methods etc will get it to show up.
I suspect that there's some wpf trickery going on behind the scenes here and it's still just a winforms browser in WPF clothing.

unless of course, any of the MS guys know better ;)

cheers,
Rob

Answer 6

I think this is a good example of why decent DWM access would be so powerful.  If we could use a DWM texture as a VisualBrush, we could surely do some cool stuff with Win32 (hWnd) controls.

Answer 7

Hi, I would like to retrun to the first question - me too can't get the LoadCompleted event. Anybody knows the answer? Or is it a bug?

Thanks!
