Help with TWebBrowser and Silverlight 1

[EnduranceMan]

Hey all

Really hoping someone can shed any sort of light on this, even a light glimmer would be nice .

I have a form with a TWebBrowser on it coded in Delphi7 as a Win32 app. If i try to browse to a silverlight application the application crashes without raising any exception. I have an exception handler around the .navigate() but it never fires, the window just closes, and recently has caused my machine to crash and restart with no warning.

The other peculiar thing about this is some Silverlight pages open fine, and others crash. And then if I browse to a page that worked 5mins later it sometimes crashes!

Any help on this would be greatly appreciated. If you could try recreate this behaviour that would be a relief to, i know im not going mad.

Regards

From testing about half or more of the links on that page cause the error.

Any feedback on this subject?

as I said, tested with TWebbrowser without problems, so the problem may lie in your code.

Hi Daddy, sorry about delay, been at Uni all week.

Did you test just the link i sent you or did you browse a few of the sample web pages?

Try these links:

ok,
testing with the the first link, gives trouble (my browser window just dissapears). I will try to look deeper into it and see what I can find.

Thanks man, much appreciated.

ok, this is really a problem.
my app just hard crashes (no exception dialog box) with those links. I am going to recreate an app in ms visualstudio to see if I have the same problem. I suspect there's something wrong between the ms activex control and silverlight.

it appears that D2009 suffers from the same problem:

My .NET test app does not crash.

so let's wait and see what embarcadero comes up with...

Thanks for the help daddy, that solves that, well for me anyway. Looks like we'll have to put silverlight aside for a while.
