Description:

This is a virtual base class for all ADO objects. This should not be used directly. You can create your own ADO controls by extending this class. Notice that is called ADO Control (from Microsoft's ActiveX Data Objects) only for compatibility. These controls have a behavior similar to MS ADO objects, but are not bound to Microsoft technologies.
