Hi,

I am trying to load a web page content in a bho project
in DISPID_DOCUMENTCOMPLETE using the code below:

But I can not detect whether the page contains frame or not. Because

if(Doc->get_frames(&Frames)==S_OK)

return always S_OK whether the page contains frame or not.
So, I can not load web pages which doesn't contain any frame.

Any help will be highly appreciated!

Thanks in advance!

          if(!pDispParams) return E_INVALIDARG;
          CComQIPtr<IWebBrowser2, &IID_IWebBrowser2>m_spWebBrowser2Tmp;
