ADO DefinedSize and ActualSize Properties

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.
