I've been spoiled by Visual Studio 2008 and Eclipse and have to do a little maintenance work on a Visual Basic 6.0 (VB6) application.
Is there an alternative/ updated IDE for Visual Basic 6.0?
A rewrite is not an option. I'm just fixing a couple of bugs and it's a big codebase.
I have never heard of an alternative IDE for Visual Basic 6.0 (VB6). However, these two (free) VB6 add-ins are indispensable and will make your life easier - especially if there is a lot of code. They are equally effective for VBA in Microsoft Office.
MZ-Tools: provides a superb collection of IDE tools - finding unused variables, unused methods, a great "search all", code snippets. Written by Carlos J. Quintero, to whom I now owe hours and hours of time.
And SmartIndenter, which takes care of all the auto-indenting. It does one thing and it does it well.
