To me VB 6 was the height of RAD IDEs

You could throw together a CRUD app in under an hour interactively.

VB was the GUI equivalent of Dataflex - you could design the screen and it would automagically create the data structures under it. I also remember, from the same period, Mantis (from Cincom Systems) that did the same for 3270 terminals and IBM mainframes.

I often say Deteflex is Ruby on Rails for the VT100.
