This is an object for assignment in DataDictionary objects to database fields with the Field_Value_Table property. It provides both values for insertion into the database and descriptions to explain each value. It is the superclass of a hierarchy of more-capable and -complex validation classes, but is usable in its own right in simple, static situations.

If the Validate_State property is set to False, entries are permitted that are not in the list; in its default True state, it requires an entry that matches one of the existing table items. If the Static_State property is set to False, the list will be filled every time the table is activated; in its default True state, the object is loaded with its list only once in each session.

You can use Find_Code_Description to retrieve the description for a given code in the DescriptionValidationTable.
