[02/03] Error with label retrieve from database

[JuzMe]

I have these codes and I could not get the values of my database to the label

My presentation layer:

Public Class searchSyllabus
    Inherits System.Web.UI.Page
    Dim a As New BusinessLayer1.Service1
    Private designerPlaceholderDeclaration As System.Object
 
    Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
        
 
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim name As String = Request.QueryString("Module")
        Dim ds As DataSet
        ds = a.getModuleAll
        Label10.Text = Convert.ToString(ds.Tables("ModuleName"))
        Label8.Text = Convert.ToString(ds.Tables("ModuleName"))
        Label9.Text = Convert.ToString(ds.Tables("ModuleCode"))
        Label7.Text = Convert.ToString(ds.Tables("Aim"))
        Label15.Text = Convert.ToString(ds.Tables("Objectve"))
        Label13.Text = Convert.ToString(ds.Tables("PreRequest"))

    End Sub
 
 
    Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
        Response.Redirect("staff.aspx")
    End Sub
 
    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Dim ds As DataSet
        ds = a.getModuleML
        Dim id As String
        id = Convert.ToString(ds.Tables("ML"))
        If id = id Then
            Response.Redirect("UpdateSyllabus.aspx")
        ElseIf id & id Then
 
 
 
        End If
 
    End Sub

My business layer as follows:

<WebMethod()> _
    Public Function populateStaffData() As DataSet
 
        Dim dataLayer As New CAPS_DATA.Service1
 
 
        Dim ds As New DataSet
        'getDataSet
        ds = dataLayer.getDataSet("SELECT * FROM staff")
 
        Return ds
    End Function
 
    <WebMethod()> _
   Public Function populateNotAssignedData() As DataSet
 
        Dim data As New CAPS_DATA.Service1
 
 
        Dim ds As New DataSet
        'getDataSet
        ds = data.getDataSet("SELECT [Module Code],[Module Name] FROM assignmodules WHERE status = 'not assigned' ")
 
        Return ds
    End Function
    <WebMethod()> _
  Public Function populateAssignedData() As DataSet
 
        Dim data As New CAPS_DATA.Service1
 
 
        Dim ds As New DataSet
        'getDataSet
        ds = data.getDataSet("SELECT [Module Code],[Module Name] FROM assignmodules WHERE status = 'assigned' ")
 
        Return ds
    End Function
 
    <WebMethod()> _
  Public Function getModule() As DataSet
 
        Dim data As New CAPS_datalayer.Service1
 
 
 
        Dim ds As New DataSet
        'getDataSet
        ds = data.getDataSet("SELECT [Module Code] FROM Module ")
 
        Return ds
    End Function
    <WebMethod()> _
  Public Function getModuleAll() As DataSet
 
        Dim data As New CAPS_datalayer.Service1
 
 
 
        Dim ds As New DataSet
        'getDataSet
        ds = data.getDataSet("SELECT * FROM Module when ModuleCode = code ")
 
        Return ds
    End Function
 
    Public Function getModuleML() As DataSet
 
        Dim data As New CAPS_datalayer.Service1
 
 
 
        Dim ds As New DataSet
        'getDataSet
        ds = data.getDataSet("SELECT    ML FROM         Module WHERE     ModuleCode = 1123")
 
        Return ds
    End Function
 
    Public Function updatemodule() As DataSet
 
        Dim data As New CAPS_datalayer.Service1
 
 
 
        Dim ds As New DataSet
        'getDataSet
        ds = data.getDataSet("Update * when ModuleCode =code")
 
        Return ds
    End Function
End Class
