How are the Data Environment modules upgraded to Visual Basic .NET?
Visual Basic 6.0 data environment modules have the file name extension .dsr. They contain information used to create ADO connections and commands to access data, which are upgraded to VB .NET using classes in the Microsoft.VisualBasic.Compatibility.VB6.BaseDataEnvironment, ADODB.Connection and ADODB.Command namespaces, respectively. The upgrade wizard converts Active Designer (.dsr) files to .vb files. Each .vb file contains a class that inherits from Microsoft.VisualBasic.Compatibility.VB6.BaseDataEnvironment.
