IEnumXXXX::Reset
Resets the enumeration sequence to the beginning.
HRESULT Reset(void);
Return Value
S_OK
Remarks
A call to this method, resetting the sequence, does not guarantee that the same set of objects will be enumerated after the reset, because it depends on the collection being enumerated. A static collection is reset to the beginning, but it can be too expensive for some collections, such as files in a directory, to guarantee this condition.
