    woot!
    with the following I think I am now getting what I am looking for.
    Thank you very much for your help
    void ListAllLinkUrls(mshtml::HTMLDocument *myDoc)
    {
            mshtml::IHTMLElementCollection *elementcollection =
    dynamic_cast<mshtml::IHTMLElementCollection*>(myDoc->all);
            if (elementcollection) {
                    System::Collections::IEnumerator *ienum =
    elementcollection->GetEnumerator();
                    while (ienum && ienum->MoveNext()) {
                            mshtml::IHTMLElement *elem=dynamic_cast<mshtml::IHTMLElement
    *>(ienum->Current);
                            if (elem) {
                                    if (elem->tagName->Equals(S"FRAME")) {
                                            mshtml::HTMLFrameBase *fb = dynamic_cast<mshtml::HTMLFrameBase*>(elem);
                                            Interop::SHDocVw::IWebBrowser2
    *wb=dynamic_cast<Interop::SHDocVw::IWebBrowser2*>(fb);
                                            if (wb) {
                                                    mshtml::HTMLDocument
    *myDoc2=dynamic_cast<mshtml::HTMLDocument*>(wb->get_Document());
                                                    ListAllLinkUrls(myDoc2);
                                            }
                                    }
                                    else if (elem->tagName->Equals(S"LINK")) {
                                            mshtml::HTMLLinkElement *le =
    dynamic_cast<mshtml::HTMLLinkElement*>(elem);
                                            Console::WriteLine("have link {0}",le->href);
                                    }
                            }
                    }
            }
    } // ListAllLinkUrls
