ADO DefinedSize and ActualSize Properties
 Complete Field Object Reference
The DefinedSize property returns a long value that indicates the
defined size of a field (in bytes).
The ActualSize property is a read-only property. It returns a long value that
indicates the actual length of a field's value. If ADO cannot determine the length of the Field object's value,
it returns adUnknown.
The DefinedSize property defines how long a field's value can be, while ActualSize
tells how long it really is.
