I recommend Network Programming for Microsoft Windows, Second Edition by Anthony Jones and Jim Ohmund. Kuphryn

Yes, that's the better method, but you stated that you wish to use the before method, and I prefer to respect ppl. wishes ;-) Anyway, this is much better what you do now, the messaging part (window) is useful only when you have to handle the winsock 1. Only disadvantage is that you have two threads - mean the whole design is more complicated due to resource locking etc. I usualy trying to design it that it uses only one thread for all that tasks. But it really depends on the application, so there cannot be a general advice except that I said. wish you good luck!

thanks...i get it now :)

Maybe this article will help you? http://www.codeproject.com/shell/dlgdhtmlevents.asp[^] Philip Patrick Web-site: www.stpworks.com "Two beer or not two beer?" Shakesbeer

It would be helpful to show the route I've been taking: CComPtr spDisp; hr = m_spBrowser->get_Document( &spDisp ); CComPtr spDoc2; hr = spDisp->QueryInterface( &spDoc2 ); CComPtr spWindow; hr = spDoc2->get_parentWindow( &spWindow ); spDoc2 = NULL; spWindow->get_document( &spDoc2 ); CComBSTR bstrParentUrl; spDoc2->get_URL( &bstrParentUrl ); In bstrParentUrl I get a bizarre value like "res//C:\DOCUMEN~1\...." I've tried many other approaches and either get an empty string or this value. Thanks Melinda.

You cannot inherit from two interfaces derived from IDispatch, because the IDispatch is not a virtual base class ( as the error message is saying, the compiler cannot decide which base class to consider for casting).You can disambiguate the cast by specifying which base class to consider ( (IDispatch*)(IInterface1*)this). Another issue is that you will have DISPID clashes from the two interfaces ( id 1 assigned to method "test" in iface 1, and for method "clone" for iface2). The solution is dispid encoding ( you can find an article on codeguru about this), manually implementing IDispatch or using tear-off objects.

I'm replying to my own thread, heh. I could use a HTML control and host it in the explorer bar. Then I could use IWebBrowser2::Navigate() to browse around the Internet because the HTML control has a member CComPtr. I read that I could use the ATL class CAxWindow<>...how do I create that as the host in the explorer bar? Thanks. Melinda.
