Parameters
dwFlags

Remarks
COM Signature
From designer.idl:
HRESULT ISelectionContainer::CountObjects(
[in] DWORD dwFlags,
[out] ULONG * pc
);
Many windows support only single item selection; they do not allow multiple items to be selected at any one time. Single selection windows always return one for their object count regardless of how dwFlags is set.
