Indicates the actual length of a field's value in bytes.
Returns a Long value.
Use the ActualSize property to return the actual length of a Field object's value. For all fields, the ActualSize property is read-only. If ADO cannot determine the length of the Field object's value, the ActualSize property returns adUnknown (-1).
In other versions of ADO the defined size of the field may be different from ActualSize, but as there is no concept of a defined size in ADO VB both these properties are identicial.
