ISelectionContainer.CountObjects(UInt32, UInt32) Method

Definition

Returns either a count of the total number of objects available or a count of the objects in the current selection.

public:
 int CountObjects(System::UInt32 dwFlags, [Runtime::InteropServices::Out] System::UInt32 % pc);
int CountObjects(unsigned int dwFlags, [Runtime::InteropServices::Out] unsigned int & pc);
public int CountObjects (uint dwFlags, out uint pc);
abstract member CountObjects : uint32 * uint32 -> int
Public Function CountObjects (dwFlags As UInteger, ByRef pc As UInteger) As Integer

Parameters

dwFlags
UInt32

[in] Flag that specifies which type of count to return. If set to GETOBJS_ALL, CountObjects returns the total number of objects. If set to GETOBJS_SELECTED, CountObjects returns the number of selected objects.

pc
UInt32

[out] Pointer to the requested object count.

Returns

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

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.
