Indicates the actual length of a field's value.
Settings and Return Values
Returns a Long value. Some providers may allow this property to be set to reserve space for BLOB data, in which case the default value is 0.
Remarks
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.
The ActualSize and DefinedSize properties are different as shown in the following example: a Field object with a declared type of adVarChar 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.
