HOWTO: Connect to SQL Server Using a Trusted Connection in VFP

• Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 6.0

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 via the ODBC dialog box in the Windows NT Control Panel, there is a check box in the lower left corner with the label, "Use Trusted Connection." 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 on a Windows NT machine:

1. Create a DataSource on the Windows NT machine 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.

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.
   
   
   1. Visual FoxPro 5.0 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.
