Syntax

'Declaration
Function CountObjects ( _
    dwFlags As UInteger, _
    <OutAttribute> ByRef pc As UInteger _
) As Integer
'Usage
Dim instance As ISelectionContainer
Dim dwFlags As UInteger
Dim pc As UInteger
Dim returnValue As Integer

returnValue = instance.CountObjects(dwFlags, _
    pc)

int CountObjects(
    uint dwFlags,
    out uint pc
)

int CountObjects(
    [InAttribute] unsigned int dwFlags, 
    [OutAttribute] unsigned int% pc
)

abstract CountObjects : 
        dwFlags:uint32 * 
        pc:uint32 byref -> int

function CountObjects(
    dwFlags : uint, 
    pc : uint
) : int

Parameters

dwFlags
Type: System.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
Type: System.UInt32%
[out] Pointer to the requested object count.

Return Value

Type: System.Int32
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.
