Why is my listbox not filling?????

I am missing something, just not sure what.
I am filling a listbox using a dataset.  There is 1 record in the table and when I do message boxes to show if there are any items in the listbox, it shows that there is the 1 item, but the item does not show in the list box.
What am I doing wrong???
Below I use messageboxes to check that there is an item.
Private Sub FillTaskList(Optional ByVal bStartUp As Boolean = False)
        Dim cT As New cTasks(ConnectionString)
 
        cT.FillList(Me.lstTasks)
        MessageBox.Show(Me.lstTasks.Items.Count)
        If bStartUp Then
            cT.SetupTaskLUGrid(Me.fpGrdTasks)
            MessageBox.Show(Me.lstTasks.Items.Count)
            Me.lstTasks.SelectedIndex = -1
            MessageBox.Show(Me.lstTasks.Items.Count)
        End If
    End Sub
 
I fill the list using
Private Function SQLCombo() As String
        Dim str As String
 
        str = "SELECT TaskID, " _
        & " TaskName " _
        & " FROM TasksLU " _
        & " ORDER BY TaskName"
 
        Return str
 
    End Function
 
 
 
 
    Public Sub FillList(ByVal cnt As ListBox)
        Dim ds As New DataSet
 
        If DatabaseToUse() = BizObjs.DBType.Access Then
            'Access Database
            Dim dc As New OleDb.OleDbConnection(ConnectionString)
            Dim da As New OleDb.OleDbDataAdapter(SQLCombo, dc)
 
            Try
 
                da.Fill(ds)
                dc.Close()
                cnt.DataSource = ds.Tables(0)
                cnt.DisplayMember = "TaskName"
                cnt.ValueMember = "TaskID"
 
            Catch ex As Exception
 
                MessageBox.Show(ex.Message)
                ''Throw ex
 
            Finally
                dc.Close()
                da.Dispose()
            End Try
        End If
 
    End Sub

This is a windows form VB 2008 net app and the listbox does not have a databind property.
Thanks
