>I am about to start a new system manufacturing system in vfp7. There will be only about 10 users, security is not an issue however the system is extensive. I am an experiecned developer for whom code is not a problem. Should I investigate a framework such as Visual ProMatrix?

Hi,
in my opinion, the choice depends on the scale of the application. If you will have only a few data entry form and the rest of the application is data processing and analyzing, the framework will not help you vastly. Contrariwise – it could bring your application redundant complexity and ungainly. But if you have to develop large application with many repeatedly used complicated rules (I mean the when and valid fields clauses as well as fonts, colors …) the framework will be very useful for you.
