Size Property (ADO Stream)
Indicates the size of the stream in number of bytes.
Returns a Long value that specifies the size of the stream in number of bytes. The default value is the size of the stream, or -1 if the size of the stream is not known.
Size can be used only with open Stream objects.
Any number of bits can be stored in a Stream object, limited only by system resources. If the Stream contains more bits than can be represented by a Long value, Size is truncated and therefore does not accurately represent the length of the Stream.
