Indicates the defined size of a Field object.
Return Values
Returns a Long value that reflects the defined size of a field as a number of bytes.
Remarks
Use the DefinedSize property to determine the data capacity of a Field object.
The DefinedSize and ActualSize properties are different as shown in the following example: a Field object with a declared type of adChar and a maximum length of 50 characters returns a DefinedSize property value of 50, but the ActualSize property value it returns is the length of the data stored in the field for the current record up to 50.
