gmBasic: Upgrade Engine

gmBasic is a code transformation tool that reads, interprets, and rewrites VB6/ASP/COM systems to one of the .NET languages (C# or VB.NET). Based on feedback from our clients and migration projects in the field, we are continuously improving gmBasic so as to help users more easily produce cleaner and more correct results. Most recently, this work includes the general improvements needed to produce build-complete C# code for a Courier Management System. This application includes 5 VB6 Dlls coded as 300K LOC of VB6 and over 150 ASP pages containing 40K LOC or markup and over 100K LOC of client-side VBScript. This distribution, Version 40.09, includes several enhancements:

  • Improves support for rewriting client-side VBScript to JavaScript in ASP to ASP.NET translations
  • Improves support for rewriting stand-alone VBScript files as JavaScript files with VBSTranslate command
  • Improves GenericCollections feature
  • Improves support for migrating Scripting.Dictionary in ASP codes
  • Improves performance of translation process (larger systems complete up to 20% faster)
  • Improves COM interface description files containing classes named "...Events"
  • Improves stub framework methods to throw NotImplemented exception
  • Improves processing Print statement with international characters
  • Continues work to allow more organization of runtime support framework
