Another advantage I see is that with all the data on a "real" server, it doesn't matter what is the front end. My front end is and will continue to be VFP. I'm 58 and see no point in learning another language especially since new programming languages are on the way. Rick Hodgin is working on VFPFree, I really hopes that he finishes this product. Alaska Software are working on a new version of Xbase which will be much more compatible with VFP, the realse date is not published yet. And Chuanbing Chen has already created a 64-bit compiler for VFP. Whoever said that VFP is dead, is wrong. It may be dying, or it may survive, only the future will tell.

>>>>Forget about that approach, you are only creating problems for yourself. Either you follow some of the tips I gave you, or you use for instance MSSQL server as data storage. I do the latter, it's much more stable, it's faster with many users and it's expandable. I now only use DBFs for some lookup tables which I include in the exe, for everything else I use SQL server and cursors.
