问题 I've connected to foxpro databases before, but only ones that have both a .dbf and .idx file. I register the Microsoft Ole DB Provider for Visual Foxpro 7.0 and use the following type of code: string sqlSTR = "SELECT * FROM TableName"; string strConnect = @"Provider=VFPOLEDB.1;Data Source=C:\Stuff.dbf;Extended Properties=dBASE IV;" And open the connection. This file, though, has a .dbf and .cdx file (which, reading online seems to be the structure of the database). When I use the connection

问题 I need to use Windows Search within my .NET application to search for certain files containing certain keywords. All of this seams easy enough using OLE DB to connect to the Windows Search data store on Windows 7. I have what I hope is a seriously easy question. I have been searching high and low for the field definitions for the SQL Query for Windows Search so I can simply work out what I can search on and what I can get back in my result set.
