Setting Field To Integer From SqlDataAdapter

How do i get the result 'puzzle' from the SQL and assign it to Integer and use it to compare with Request.Form ? 

 Protected Sub Page_Load(ByVal sender As Object, _

                      ByVal e As System.EventArgs) Handles Me.Load

 

            Dim connString As String = _           ConfigurationManager.ConnectionStrings("Local_LAConnectionString1").ConnectionString

 

           Dim strsql As String = _

           "Select CustomerID,CustomerNo,dbo.LA_DEC(Passkey) as passcode,dbo.LA_DEC(PuzzleKey) As puzzle, PuzzleFlag, NickName from Customers Where CustomerNo = '" & myAccount & "'"

            Using myConnection As New SqlConnection(connString)                  Dim myCommand As New SqlCommand(strsql, myConnection)

 

                  myConnection.Open()

                   Dim PuzzleDataSet As New DataSet

                  Dim PuzzleAdapter As New SqlDataAdapter(myCommand)                                    //                              <----    Coding here

 

 

 

                   myConnection.Close()

         End Using

 

End Sub
