Remarks

In Visual Basic 6.0, data-bound forms were automatically created when you dragged database elements from a Data Environment onto a form. The Data Environment handled all the mapping between Visual Basic 6.0 and the ADO data layer. When an application is upgraded to Visual Basic, a BaseDataEnvironment is created to enable the ADO-related code.

Note

Functions and objects in the Microsoft.VisualBasic.Compatibility.VB6 namespace are provided for use by the tools for upgrading from Visual Basic 6.0 to Visual Basic 2008. In most cases, these functions and objects duplicate functionality that you can find in other namespaces in the .NET Framework. They are necessary only when the Visual Basic 6.0 code model differs significantly from the .NET Framework implementation.
