Getting IMarkupServices from IHTMLDocument2

I'm trying to get an IMarkupServices interface pointer (amonst other things) from an IHTMLDocument2 pointer which was obtained from a Running object (Internet explorer application already loaded with a web page). I noticed that I also couldn't place the document into edit mode using IHTMLDocument2::put_designMode(L"On") which returns E_INVALIDARG.

//IHTMLDocument2 *pIHTMLDoc2; // valid pointer to document
IMarkupServices *pIMS;

hr = pIHTMLDoc2->put_designMode(L"On"); // returns E_INVALIDARG
.
.
// following returns E_NOINTERFACE
hr = pIHTMLDoc2->QueryInterface(IID_IMarkupServices,(void **)&pIMS);

This is exactly how microsoft says to do it, yet it doesn't work? Any ideas? Is it because iexplore.exe limits its mshtml editing somehow?

Hi Chuck,

I know this is a bit late... Windows 2000, VC++ 6.0 and no SDK gets the same results.

If I install latest SDK (March 2006), I get a Link Error 1103 - LNK1103 - UUID library is corrupt. M$ no longer supports VC++ 6.0. I'm told to rollback to February 2003. I'm trying to find a disc now...

Code:

---

CComPtr< MSHTML::IHTMLDocument2 > Document;
S_OK = Document.CoCreateInstance( CLSID_HTMLDocument );
...
//
E_NOINTERFACE == 0x80004002
E_NOINTERFACE = Document->QueryInterface( IID_IMarkupServices );
