There are two problems here. First, OLEDB Providers do not show up in ODBC because they aren't ODBC. Second, you need a 64 bit OLEDB Provider for VFP and Microsoft has not and will not create one. There are some third-party ones that may work.

>I want to know if there is any way to connect VFP9 database from any other language/software like Sharepoint or SSRS. I want to read data from VFP9 database for deploying some reports to SharePoint 2010 using SSRS (SQL Server Reporting Services). SSRS and Sharepoint is installed on Windows Server 2008 64bit. Is there any ODBC (VFP9) driver which I can install on this OS?
>I have installed VFPOLEDB but still there is no drivers appear in ODBC window.
