Hidden. Returns an IEnumVARIANT interface pointer.

The IEnumVARIANT interface is used by low level language like C++ to enumerate collection keys. Item value associated with each key can be retreived with the Item property. High level languages do not use this interface directly, but automatically throught their enumeration implementation (For Each in VB, foreach in C#, ...). Collection items cannot be added, removed or modified during an enumeration.
