Conversion of Fox 2.6 (DOS & WIN) to VFP6

[Grimwaldi]

I am looking into converting our old faithfull 2.6 Fox Apps to VFP6. I am not going to do a partial convertion as this will take more time in the end, but I am puzzled by the best approach.

I am in two minds as to go for 2-Tier, ie Form front end using business rules in objects, ie Customer form using bisCus class's methods and attributes.

Or to go for classic data bound to form, which either calls external progs in procedure or call new methods created on form.

Oh I am also looking into using a framework, should I use the standard one or use codebook's?

Any comments

Thanks in advance.

Visual ProMatrix is a good framework.

Obviously much depends on your needs - size of the app, it's complexity and "unique" requirements, your experience, the time you have to learn a framework and the money you have to spend. For some prelim comparisons, check out

We've been doing this over the past year. FWIW I would really try to upgrade to vfp 8 for the conversion. I had ambitions of a major rewrite but life being what it is we are starting with a pretty straight port of the 2.6 apps - advantage is the users are not confused - minimal training curve. Also, I find that getting on top of OOP is no small deal.

There are numerus medium apps accessing the same tables, ie the tables are 260MB in size.

It varies from sales, to despatch software. It's the reports that I think will be difficult as they use overlays for the output, so this will be a lot of work converting, but what about databases vs free tables?
