Deletes a member by DISPID.
HRESULT DeleteMemberByDispID( DISPID id );
Member identifier. Uses GetDispID or GetNextDispID to obtain the dispatch identifier.
Returns one of the following values:
Member exists but cannot be deleted.
If the member is deleted, the DISPID needs to remain valid for GetNextDispID.
If a member with a given name is deleted and later a member with the same name is recreated, the DISPID should be the same. (Whether member names that differ only by case are the "same" is object-dependent.)
BSTR bstrName; DISPID dispid; IDispatchEx *pdex; // Assign to pdex and bstrName if (SUCCEEDED(pdex->GetDispID(bstrName, fdexNameCaseSensitive, &dispid))) pdex->DeleteMemberByDispID(dispid);
