ActualSize property (ADO)

  • Article

Applies to: Access 2013, Office 2013

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. 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.
