im trying to extend pelle's win32 sample code by adding a URI
listener.
i inherited & stubbed nsIURIContentListener in webbrowserchrome.
i added this line after baseWindow->Create():
//rv returns 0
rv = webBrowser-
>SetParentURIContentListener((nsIURIContentListener*)(chrome.get()) );
i get a unhandled exception (0×0041b025) when i click on a link. here
is the stack:
nsCOMPtr_base::assign_with_AddRef()
nsCOMPtr::operator=(nsIWebBrowser * rhs=0×025371d0)
WebBrowserChrome::SetWebBrowser(nsIWebBrowser *
aWebBrowser=0×025371d0)
im new to mozilla stuff - am i creating the listener correctly? do i
need to replace the assignment with some sort of addref?
thanks
