   Dim table1 As DataTable = MakeTable ( "idTable1", "thing1" )
   Dim table2 As DataTable = MakeTable ( "idTable2", "thing2" )
   myDataSet.Tables.Add ( table1 )
   myDataSet.Tables.Add ( table2 )
   Response.Write ( myDataSet.DataSetName, _
      myDataSet.Tables.Count )
End Sub

Private Function MakeTable ( c1Name As String, _
      c2Name As String ) As DataTable
   Dim myTable As New DataTable
   Dim myColumn As DataColumn
   ' add two DataColumns
   myColumn = New DataColumn ( c1Name, _
      System.Type.GetType ( "System.Integer" ) )
   myTable.Columns.Add ( myColumn )
   myColumn = New DataColumn ( c2Name, _
