The Containers collection contains zero or more Container object. This
collection can not be created directly.
You can access individual items using the Item method. The Item
method use either an index or the unique identifier of the item. The index is a
number, the first item of the collection has the index 1 and the last item of
the collection has the index equal to the value of the Count property.
The index is a temporary identifier valid only for the life of the collection.
It is better to use the unique identifier of the item (see ID)
to retrieve it. You can parse the collection with two methods. The first method
is to do a loop from 1 to Count property and the second method is to use
the NewEnum property with a "For Each...Next" instruction.
