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.
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. Fields with a DefinedSize greater than 255 bytes are treated as variable length columns.
