I am in the process of spec-ing a payroll product (we sell to the staffing industry). I am going to define it as a n-tier product. I am going to use VFP in the middle and probably in the back too. The UI is unknown, VB, VFP, ASP ????.

Frameworks is the question. You mentioned WWWC, xworks. What are these and sould I stay with a VFP framework?

Currently we are using an in-house framework and I am not too happy with it, so I am in the market to purchase.

Any help would be welcome. Anyone can help, thanks.
