Hi,

>>Can you clarify what you mean here. It sounds as if you expect to place a copy of a SQL database on the customers machine and access it via the VFP OLEDB drivers without an installed instance of SQLServer. You can't do that.

Sorry, but I'm still not clear on what you are proposing. It still sounds as if you intend for customers to have their own copy of the data on their machine. If so, regardless of whether you are accessing it from VFP or .NET, they will need an instance of SQL server installed. The only alternative (AFAIK) would be to use the CE standalone database (SDF) files. In that case there are a small set of .NET DLLs that can be embedded in your application so that no SQL installation is required. That may or may not be a viable option - this information might help: http://download.microsoft.com/download/A/4/7/A47B7B0E-976D-4F49-B15D-F02ADE638EBE/Compact_Express_Comparison.doc
