This section describes how to call the constructor of a Database object in Visual Basic .NET.

The constructor of any object can be called by using the New operator. The Database object constructor is overloaded and the version of the Database object constructor that is used in the sample takes two parameters: the parent Server object to which the database belongs, and a string that represents the name of the new database.

Calling an object constructor

  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:

    Microsoft.SqlServer.ConnectionInfo.dll

    Microsoft.SqlServer.Smo.dll

    Microsoft.SqlServer.SqlEnum.dll

    Microsoft.SqlServer.SmoEnum.dll

  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.

Example

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Declare and define a Database object by supplying the parent server and the database name arguments in the constructor.
Dim d As Database
d = New Database(srv, "Test_SMO_Database")
'Create the database on the instance of SQL Server.
d.Create()
Console.WriteLine(d.Name)
