DOCUMENT:Q159590 20-OCT-2000 [foxpro] TITLE :HOWTO: Connect to SQL Server Using a Trusted Connection in VFP PRODUCT :Microsoft FoxPro PROD/VER::2.5,2.6,3.0,3.0b,5.0,6.0 OPER/SYS: KEYWORDS:kbinterop kbDatabase kbODBC kbvfp300 kbvfp500 kbvfp600 kbGrpDSFox kbGrpDSMDAC kbDSuppor ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 6.0 - Microsoft Data Access Components versions 2.5, 2.6 ------------------------------------------------------------------------------- SUMMARY ======= SQL Server can be installed utilizing either Standard, Windows NT Integrated or Mixed security. The Trusted Connection is available only under Windows NT. When creating a new DataSource to SQL Server via the ODBC dialog box in the Control Panel of a client machine, there is a radio button check box in step 2 with the label "With Windows NT authentication using the network login ID." Checking this option requests a trusted connection to SQL Server regardless of the security mode of the server. For information about the SQL Server login security mode and trusted connections, see the Microsoft SQL Server Administrator's Companion. Once a DataSource has been created using a Trusted Connection, a connection can be created without supplying a user name and password. The user's Windows NT userid must exist on SQL Server. To connect from Visual FoxPro via an available DataSource: 1. Create a DataSource with the Trusted Connection box checked. 2. In a program or Command window type: x=sqlconnect("datasource name here"). 3. Print the value of x, such as "? x". If x returns a positive number, then a valid connection was established. To connect from Visual FoxPro via an available connection from a Window NT machine: 1. Open up a project in Visual FoxPro. 2. Select Connections. 3. Select New. 4. Choose a valid DataSource with the Trusted connection option checked. 5. Leave the userid and password text boxes empty. a. Visual FoxPro 5.0 and 6 allows you to verify the connection via a command button. 6. Select Remote Views from the project. 7. Select New. 8. Use the Connection created by the steps above.
