You can use LINK Server of SQL Server. This allow Fox DB to be like part of SQL Server then You can now query FoxDb via TCP/IP or SQL name Piple.The most benefits is you are using Client/Server not the File Sharing Approach just like sharing Folder.In case you only pass SQL Command to the network and get the result. By then you can now easy integrate it to your web.

EXEC sp_addlinkedserver
  'FOXDB',
   '',
   'VFPOLEDB.1',
   'D:\nosij\vinstron\MIS\Data\mis.dbc',
   NULL,
   'VFPOLEDB.1'

To Execute Query

Select *
 from FOXDB...Sales

Hope this will help
