Parameters

dwFlags: Type: System::UInt32

Remarks

COM Signature

From designer.idl:

C++

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.
