I assume you mean Visual FoxPro. I can only consider C# solutions. In fact, my company is switching from VFP to C# largely to address performance problems between VFP and MS SQL 2000. I assume that there is a optimal method in C#.

>Use a vfp COM object to query and process the data or feed the data into a local instance of MSDE/SQL server... There even is an article by Kamal Petal (Kemal Patal ? I am getting old) on using vfp to query .Net Datasets AFAIR.
