How To Upgrading Applications Created in Visual Basic 6.0

Visual Basic 2008 provides the ability to upgrade applications created in Visual Basic 6.0 so that you can continue development, taking advantage of the benefits of the .NET Framework. When you first open a Visual Basic 6.0 project file (.vbp), the Upgrade Wizard appears. A command-line tool is also provided for upgrading projects outside the development environment.
With Visual Basic 2008, you can upgrade applications created in Visual Basic 6.0 so that you can continue development, taking advantage of the benefits of the .NET Framework. When you first open a Visual Basic 6.0 project file (.vbp), the Upgrade Wizard appears. You can also upgrade projects outside the development environment with the provided command-line tool.
The upgrading tools modify code in your project to comply with Visual Basic 2008 syntax and replace any forms and controls with Visual Basic 2008 equivalents. Because of the differences between Visual Basic 6.0 and Visual Basic 2008, some parts of your project may not upgrade correctly. In these cases, you receive an upgrade report to guide you through the process of modifying the application.

If you are not ready to upgrade your Visual Basic 6.0 application, you can still take advantage of the benefits of the .NET Framework by using Interop Forms Toolkit 2.0. Interop Forms Toolkit 2.0 enables you to create new forms or UserControls in Visual Basic 2008 and use them in your Visual Basic 6.0 application.
Interop Toolkit 2.0 can be downloaded for free from the page on the MSDN Web site
