There are two different libraries supplied by ADO for use in your projects. To add either of these libraries, you must select Project | References from the VB IDE. In the list of libraries, you will find two libraries relating to ADO, the Microsoft ActiveX Data Objects 2.0 Library (ADODB) and the Microsoft ActiveX Data Object Recordset 2.0 Library (ADOR). The ADODB library contains the complete ADO object model and full ADO functionality; you will use this library for most of your full-scale applications.
