vbeTwister is a Windows (XP - 8.1) 32 bit add-in for Microsoft VBA (MS Office 2000 - 2013, ...) and Microsoft Visual Basic 6.
The VBA IDE (VBE6.DLL) was released by Microsoft in 1999 as part of MS Office 2000. Since then Microsoft didn't improve the software at all. As a result it lacks a lot features other code editors/IDEs nowadays use to have. During the years many third party software vendors (like AutoDesk etc.) licenced the VBA technology (language including the VBE) to upgrade their program into a plattform.
Microsoft Visual Basic 6, released by Microsoft in 1998, is a very simular IDE and provides the same add-in API. Still thousands of developers are using these two products, maintaining and developing Visual Basic (for Applications) software. The add-in vbeTwister upgrades the IDE by adding a bunch of features and increases therefore the coding comfort and the productivity.
