How do you set an interop managed class instance to an
actual com created instance.

why doesn't this work????

CComPtr<IHTMLDocument2> spDoc;

mshtml::IHTMLDocument2* doc=(mshtml::IHTMLDocument2*)

Off the top of my head, can you use

System::Object *pObject =
System::Runtime::InteropServices::Marshal::GetObje ctForIUnknown(spDoc.GetInt
erfacePtr())

and then cast that to your managed interface pointer?

I haven't tested it but it might get you started.
