Visual Basic Upgrade Wizard
Visual Basic .NET enables a fundamental shift from traditional Windows development to building next-generation Web and n-tier applications. For this reason, your code will need to be upgraded to take advantage of Visual Basic .NET.
This happens automatically when you open a Visual Basic 6.0 project in Visual Basic .NET: the Upgrade Wizard steps you through the upgrade process and creates a new Visual Basic .NET project (your existing project is left unchanged). This is a one-way process; the new Visual Basic .NET project cannot be opened in Visual Basic 6.0.
When your project is upgraded, the language is modified for any syntax changes and your Visual Basic 6.0 Forms are converted to Windows Forms. In most cases, you will have to make some changes to your code after it is upgraded. This is required because certain objects and language features either have no equivalent in Visual Basic .NET, or have an equivalent too dissimilar for an automatic upgrade. After the upgrade, you may also want to change your application to take advantage of some of the new features in Visual Basic .NET.
To help you make the changes, after your project is upgraded, Visual Basic .NET adds an upgrade report to your project itemizing any problems, and inserts comments into your upgraded code alerting you to statements that will need to be changed. Because these comments are displayed as 'TO DO' tasks in the new Task List window, you can easily see what changes are required, and navigate to the code statement simply by double-clicking the task. Each task and item in the upgrade report is associated with an online Help topic giving further guidance as to why the code needs to be changed, and what you need to do
