GetExtension not working

User (Legacy)

Recommended Posts

I can't get the GetExtension function to work. Can you tell me what I am 

doing wrong?

Sample code: (Using VC++, DLL, Latest service pack)

// Add the annotation extension

IAnnListPtr pAnnList;



// Now try getting it back.


HRESULT HR = pChart->raw_GetExtension("AnnotateX.AnnList", &pList);

HR now contains CO_E_CLASSSTRING ("Invalid class string.") I tried

"AnnotationX.AnnList" as well, since I saw the other post in this newgroup,

but I get the same HRESULT. What string should I be using?
