A Migration Development Platform which supports our tool-assisted rewrite methodology.
Four types of migrations are supported:
* VB Classic to C#.NET
* VB Classic to VB.NET
* ASP Classic to ASP.NET (web application projects with C#.NET code behind)
* ASP Classic to ASP.NET (web application projects with VB#.NET code behind)
Both VS2005 and VS2005 project formats are supported as well as choice of .NET framework version with VS2008. VS2003 available on request.
gmStudio is a complete migration managment and automation environmnent that support preparation, translation, and verification activities. The gmStudio main form is shown below.

A detailed description of this form and the tool in general is in the gmStudio User's Guide. This tool is designed to support the migration of Visual Basic Applications to .NET via translation to C# or VB.NET. It is a key component of our tool-assisted migration methodology. We use this tool to develop custom translation and refactoring solutions for our clients' migration projects -- large or small. For example, we employed this tool with great success in the BMW Financial Services "Visual Basic Retirement" Project. The purpose of this project was to migrate to .NET their entire enterprise portfolio of about 500 business applications (totaling more than one million lines of VB6 code) via automated translation and refactoring of VB6/COM to C#/.NET. See BMW Financial Services .NET Adoption Case Study
The hallmark characteristics of gmBasic include the following:
* Accurate correctly transforms your application codebase to logically equivalent .NET code
* Flexible can be configured to produce translations that meet your custom restructuring and coding conventions; for example replacing COM components with managed components (e.g., ADODB to ADO.NET)
* Scalable handles multiple related projects (combinations of VB6 components and ASP pages) as a single, logical migration unit, not just a batch of separate translations. The result is a coherent, consistent target codebase with no interop between migrated components.
* Extensible - can be easily extended to recognize additional libraries or restructuring rules. We have an extensive XML-based migration configuration and a migration API.
* Choice of Language - supports translation to both C# and VB.NET. This also applies to conversion of VBScript in your ASP pages to C# or VB.NET code behind.
* Complete - supports all common VB6/ASP language features and COM components distributed with VB and Windows
* Mature - is based on proven principles of compiler design and extensive experience in large scale migration projects.
* Fast! - can translate typical VB projects in a few seconds (e.g., it takes 12 minutes to compile a huge codebase of 175 VBPs, 3000 files, and 1.8 million lines of code).
The best way to learn about gmStudio is to see it for yourself in the context of your application. Contact us to request a demo or to find out about our migration assessment service. You will also find a number of white papers about our technology in the Downloads section.
"Under the hood", gmStudio is a highly configurable, robust computer language processing and transformation system called gmBasic. gmBasic is the result of over thirty years research and development in the area of compiler design and semantic tranlsation. gmBasic has three basic components:
* Compiler: Builds a comprehensive semantic model of the source codebase and external COM components
* Analyzer: evaluates and restructures the model to fit the desired architecture patterns.
* Author: interprets the optimized model to generate clean, correct code that meets custom standards and conventions.
