not found too, I guess that when you use MFC in combination with the
Classwizard things are handled hidden for the programmer. Nonetheless:
I give you the following information for the better of it:

im my .h file

afx_msg LPDISPATCH GetRelationQuerierEx(const VARIANT FAR& vaIDs,long
lDummy);

the first argument is the safearray, the second the long

in my .cpp file

DISP_PROPERTY_PARAM(CDispCore, "RelationQuerierEx",
GetRelationQuerierEx, SetNotSupported, VT_DISPATCH, VTS_VARIANT
VTS_I4)
