Thank you but it does't work. I always have 0x8000ffff failure code.

In fact i get a web browser like this :
	nsCOMPtr<nsIWebBrowser> webBrowser;
	rslt =3D serviceManager->\
		GetServiceByContractID(\
		"@mozilla.org/embedding/browser/nsWebBrowser;1", \
		NS_GET_IID(nsIWebBrowser), \
		getter_AddRefs(webBrowser));=09

is that correct ?=20

After i put the lines
	nsCOMPtr<nsIWebNavigation> nav  =3D do_QueryInterface(webBrowser);

	nsCOMPtr<nsIDOMDocument> doc;
	rslt =3D nav->GetDocument(getter_AddRefs(doc));
	if(NS_FAILED(rslt)) return rslt;

but "doc" is still and always NULL...

I think the problem is how i can get a correct webBrowser object.

someone has an idea of the reason of the problem ?
