How can I upgrade a Visual Basic 6.0 application that accesses ODBC or OLE DB data sources to Visual Basic .NET?
You must upgrade the programmer interface used to interact with the data source. Depending on the data source, this interface will be DAO, RDO, or ADO. Information on how to upgrade DAO, RDO, and DAO code is provided in Chapter 12, “Upgrading Data Access.” However, if the resources are available to do so, it is recommended that you upgrade any data access interfaces to ADO.NET.
