The following works when run in Winxp but when transported to WinMe
m_pDocument is null after CoCreateInstance. Thus, trapping on
m_pDocument->load().


#include <msxml2.h>
....
CComPtr <IXMLDOMDocument> m_pDocument;
....
hr = m_pDocument.CoCreateInstance(CLSID_DOMDocument);
....
VARIANT_BOOL loadResult;
COleVariant fileName(m_ConfigFileNameWithPath);
hr = m_pDocument->load(fileName, &loadResult);


Any ideas on root problem and solution? Something to do with msxml2
not existing in WinMe maybe? Is so, what does exist?

Thanks...

It would appear from the code that WinMe machine doesnt have the relevant
COM server installed. You will need to install it first. I have no idea if
its even supported on that OS. Good luck.

Thanks for the reply.

Further info, CoCreateInstance hr = 80040154 = REGDB_E_CLASSNOTREG =
Class not registered.

File %SystemRoot%\System32\msxml2.dll does not exist and I'm thinking
I need this. Although Msxml.dll does exist. Best I can tell, this
will install version 2:

I agree with Ajay.

Moreover, if you are interested in XML parsing, you might consider also
TinyXML:
