How to: Connect to a Remote Instance of SQL Server by Using Windows Authentication in Visual Basic .NET

This section describes how to write an SMO application in Visual Basic .NET that connects to a remote instance of SQL Server by using Windows Authentication.

When you connect to an instance of SQL Server by using Windows Authentication, you do not have to specify the authentication type. Windows Authentication is the default.

  1. Start Visual Studio 2005.

  2. From the File menu, select New Project. The New Project dialog box appears.

  3. In the Project Types pane, select Visual Basic. In the Templates pane, select Console Application.

  4. (Optional) In the Name box, type the name of the new application.

  5. Click OK to load the Visual Basic console application template.

  6. On the Project menu, select Add Reference item. The Add Reference dialog box appears. Select Browse and locate the SMO assemblies in the C:\Program Files\Microsoft SQL Server\90\SDK\Assemblies folder. Select the following files:





  7. On the View menu, click Code.-Or-Select the Module1.vb window to display the code window.

  8. In the code, before any declarations, type the following Imports statements to qualify the types in the SMO namespace:

    Imports Microsoft.SqlServer.Management.Smo
    Imports Microsoft.SqlServer.Management.Common
  9. Insert the code that follows this procedure into the main program.

  10. Run and build the application.

The example is Visual Basic .NET code that connects to the remote instance of SQL Server by using Windows Authentication.

'Connect to a remote instance of SQL Server.
Dim srv As Server
'The strServer string variable contains the name of a remote instance of SQL Server.
srv = New Server(strServer)
'The actual connection is made when a property is retrieved. 
'The connection is automatically disconnected when the Server variable goes out of scope.

The string variable strServer contains the name of the remote instance.
