    flags As UInteger, _
    <OutAttribute> ByRef pc As UInteger _
) As Integer

public virtual int CountObjects(
    uint flags,
    out uint pc
)

public:
virtual int CountObjects(
    unsigned int flags, 
    [OutAttribute] unsigned int% pc
)

abstract CountObjects :

public function CountObjects(
    flags : uint, 
    pc : uint
) : int

Parameters

flags
Type: UInt32

[in] This is either GETOBJS_ALL to count all objects, or GETOBJS_SELECTED to count only the selected objects.

pc
Type: UInt32%

[out] Returns the number of objects.

Return Value

Type: Int32
If successful, returns S_OK; otherwise, returns an error code.

Implements

ISelectionContainer.CountObjects(UInt32, UInt32%)

Remarks

This method is used to handle multiple selectable objects in the Properties window. A language service typically needs only the one DocumentProperties object and the base method handles this automatically.

This method is an implementation of the CountObjects method on the ISelectionContainer interface.

The base method returns a count of 1 if the DocumentProperties object is visible; otherwise, the base method returns 0. The base method always returns a success code of S_OK.
