How to: Create a Full-Text Search Service in Visual Basic .NET
This section describes how to create a full-text search service in Visual Basic .NET.
The code example creates a full-text search catalog for the ProductCategory table in the AdventureWorks sample database. It then creates a full-text search index on the Name column in the ProductCategory table. The full-text search index requires that there is a unique index already defined on the column.
Creating a full-text service
Start Visual Studio 2005.
From the File menu, select New Project. The New Project dialog box appears.
In the Project Types pane, select Visual Basic. In the Templates pane, select Console Application.
(Optional) In the Name box, type the name of the new application.
Click OK to load the Visual Basic console application template.
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
On the View menu, click Code.-Or-Select the Module1.vb window to display the code window.
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.CommonInsert the code that follows this procedure into the main program.
Run and build the application.

'Reference the AdventureWorks database.
Dim db As Database
db = srv.Databases("AdventureWorks")
'Reference the ProductCategory table.
Dim tb As Table

Dim ftc As FullTextCatalog

ftc.IsDefault = True
'Create the Full Text Search catalog on the instance of SQL Server.
ftc.Create()
'Define a FullTextIndex object varaible by supplying the parent table argument in the constructor.
Dim fti As FullTextIndex
fti = New FullTextIndex(tb)
'Define a FullTextIndexColumn object variable by supplying the parent index and column name arguements in the constructor.
Dim ftic As FullTextIndexColumn
ftic = New FullTextIndexColumn(fti, "Name")
'Add the indexed column to the index.
fti.IndexedColumns.Add(ftic)
fti.ChangeTracking = ChangeTracking.Automatic
'Specify the unique index on the table that is required by the Full Text Search index.
fti.UniqueIndexName = "AK_ProductCategory_Name"
'Specify the catalog associated with the index.
fti.CatalogName = "Test_Catalog"
'Create the Full Text Search index on the instance of SQL Server.
fti.Create()
