This book does not cover the indepth nature of more obscure DAO commands, and instead makes incorrect assumptions about their usefulness or necessity. For example, with regard to the Refresh parameter (TableDefs). It may not be needed in a single-user database, and in any case using the Refresh method often appears to have no effect. Creating a table, or field, using DAO and then immediately referencing it thru DAO will cause errors because DAO does not see the Table/Field until the Refresh method is used on the collection. For amusement, check out the editor's note on the back cover. This is not a Steve Roman book by a long shot!
