Type 'SQLDataSetCommand' is not defined. ??

Ok, I'm trying to use a Code Behind with a Datagrid that simply pulls info out from a MS SQL DB
However, i get the error: Type 'SQLDataSetCommand' is not defined.  What gives?  I am copying the source code from: http://www.dotnetjunkies.com/tutorials.aspx?tutorialid=54

Also, can you recommend any good sites to learn more about code behind's?  I am looking into 4guysfromrolla now.

THANKS!



Here is my code:

Option Strict Off

Imports System
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.Web.UI.HtmlControls
Imports System.Data
Imports System.Data.SQLClient

Public Class myPage : Inherits Page

     Public myDataGrid As DataGrid
     Public myLabel As Label
     
     Public Property myProp As String
          Get
               Return myLabel.Text
          End Get
          Set
               myLabel.Text = Value
          End Set
     End Property
     
     Public Sub Page_Load(Source As Object, E As EventArgs)
          Dim ds As New DataSet
          Dim dsc As SQLDataSetCommand
          DIM dsc = New SQLDataSetCommand("SELECT CompanyName, ContactName, ContactTitle FROM Customers", _
                                                  "server=localhost;uid=sa;pwd=;database=Northwind;")
          dsc.FillDataSet(ds, "Customers")
          myDataGrid.DataSource = ds.Tables("Customers").DefaultView
          myDataGrid.DataBind()
     End Sub


End Class
