> On west wind technology I download document and shareware for study,I think it's a good product and good for VFP base.But I'm not sure it's good for develope by SQL SERVER base.Do you have any idea.

Sure, West Wind works fine with SQL Server backend, with your coding done in VFP. In fact, the most recent versions of Web Connection have the capability built-in to store some of the necessary "system" tables in SQL Server. Take a close look also at the wwSQL class, which can handle queries.

All around, it's a very good product, with new features added on a regular basis and very good tech support from the author as well as many of the developers using it.
