>Hi, I´m programming in VPF for about a year. I have finished seven Single User Apps but now i´m working in my first multiuser app (it´s a stock and inventory system, it has been working fine on a single computer but now i have to make it work for six users, i have a DBC with four main tables and my server has win2k) I want to ask you for suggestions because i´m very confuse with the use of Datasessions, Transactions, Buffers, etc. What is the best way to do the job ?

You should investigate one of the commercial frameworks available for VFP. This will make your life much easier.
