How to: Set Various Properties Before an Object is Created in Visual Basic .NET

SQL Server 2005

This section describes how to set required properties before you create an object.

The code example shows how to directly set the AnsiNullsStatus property of the Table object, and how to create and add columns before you create the Table object.

  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.

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Create a new table in the AdventureWorks database. 
Dim db As Database
db = srv.Databases("AdventureWorks")
Dim tb As Table
'Specify the parent database, table schema and the table name in the constructor.
tb = New Table(db, "Test_Table", "HumanResources")
'Add columns because the table requires columns before it can be created. 
Dim c1 As Column
'Specify the parent table, the column name and data type in the constructor.
c1 = New Column(tb, "ID", DataType.Int)
tb.Columns.Add(c1)
c1.Nullable = False
c1.Identity = True
c1.IdentityIncrement = 1
c1.IdentitySeed = 0
Dim c2 As Column
c2 = New Column(tb, "Name", DataType.NVarChar(100))
c2.Nullable = False
tb.Columns.Add(c2)
tb.AnsiNullsStatus = True
'Create the table on the instance of SQL Server.
tb.Create()
