Question

I’m having trouble compiling one of our legacy COM components. I get the following compiler error:

error C2501: 'IXMLDOMNode' : missing storage-class or type specifiers
error C2061: syntax error : identifier 'IXMLDOMNode'

On this line of code in a .h file:

IXMLDOMNode* CreateChildNodeOfItem(IXMLDOMNode* pNode, DOMNodeType nodeType, CString strName);

I assumed IXMLDOMNode was coming from this library:

#include <msxml.h>

Do I need to install a missing SDK?

Edit:

// stdafx.h : include file for standard system include files,
//  or project specific include files that are used frequently, but
//      are changed infrequently

#endif // _MSC_VER > 1000

#include <msxml.h>

I changed the way I’m including msxml and it seems to have fixed the compiler errors. I changed:

#include <msxml.h>

to

#import <msxml.dll> raw_interfaces_only
using namespace MSXML;
