To upgrade a Visual Basic 6.0 project to Visual Basic .NET 
----------------------------------------------------------
1. Open your project in Visual Basic 6.0. On the File menu, choose 
   Make projectname. Run the application and make sure that there 
   are no errors. 

2. Start Visual Studio .NET. On the File menu, choose Open, Project. 

3. In the Open Project dialog box, browse to the location of the 
   Visual Basic 6.0 project and select the project (.vbp) file. 
   This will launch the Visual Basic Upgrade Wizard. 

4. On the second page of the wizard, choose from the available 
   upgrade options. The options will vary depending on the type of 
   project being upgraded. 
   TIP:  For an explanation of available options, press F1 while in 
         the wizard.

5. On the third page of the wizard, enter the location where the new 
   project will be created. 
   NOTE:  Each Visual Basic .NET project must be in its own folder. 
          If you specify a folder that contains files, you will be 
          prompted to choose a different folder.

6. On the fourth page of the wizard, click Next to begin the upgrade 
   process. When the process is complete, the new project will appear 
   in Solution Explorer. 

7. In Solution Explorer, double-click the _UpgradeReport.htm node to 
   open the upgrade report. 

8. Review the upgrade report. Any errors must be fixed before you can 
   run the application. Any warnings should be examined to make sure 
   that they do not affect application behavior. 
   TIP:  For an explanation of any error or warning, click on the 
         description to display a Help topic.

9. On the Debug menu, choose Start. Run the application and make sure 
   that there are no errors and that the behavior is the same as it 
   was in Visual Basic 6.0. 
   NOTE:  The Upgrade Wizard cannot catch all possible incompatibilities; 
          it is possible that you will encounter additional errors when 
          you run the application.
