write following statement at the begining of ur code
#import "msxml.dll"

this should work otherwise
try including the header file for _variant_t class too.
i.e. comutil.h

Sorry if u felt for what I said Smile | :)

I just wanted to tell u that never ever post ur project code (change name of classes & DS) and post only related code.
Ok coming back to the point..
actually two weeks before i was facing the same problem
i wanted to read a xml file
& I did whatever I told u before but,
i don't know what u hv done so far & Y from the hell the problem is coming to u .
by the way I did all these things on VS2005

one more thing i would like to mention that
import the dll where u are declaring
IXMLDOMDocument* m_pIDomDoc

I mean in main frame

MainFrm.h

#pragma once
#import "msxml.dll"

class YourClass
{
public:
IXMLDOMDocument* m_pIDomDoc;
}
try this.
