As I blogged before, the release of the VB Upgrade Companion v3.0 is due within the next few weeks. In this version we concentrated on three major areas:
- Automation: We analyzed the data from several million lines of code to determine the most common causes of manual intervention, and, by making some strategic changes to the way the code is generated, managed to reduce the amount of both EWIs (Error, Warning and Information messages) and compilation errors significantly on large (>1 million Lines of Code), complex applications. Also, depending on the VB6 features used, the VBUC now automates the migration of even more smaller applications and components completely!
- New Features: The VBUC v3.0 also contains additional features, such as the migration of the IsMissing statement and increased support for additional third party components. We are also integrating the VBUC with brand new online documentation resources that should help you as you perform the migration!
- Code Quality: The Visual Basic Upgrade Companion always tries to generate high-quality code that looks as if it was originally written in .NET. This increases the maintainability of the migrated application, and allows developers joining the project at a later date to very quickly start working on the codebase. Because of the great differences between Visual Basic 6.0 and VB.NET/C#, however, achieving this goal is not always possible. For this release we continued increasing the quality of the migrated code, including minor refactorings to control structures, and adding things like support for translating additional error handling statements to try/catch statements.
All of these was supported by some significant changes we did under the hood, which should make it easier to add new features in the future (including customer-specific customizations) and reduced the memory footprint significantly, while increasing migration speed. Watch this space for more details as the release date approaches!
