vb 2005 express and listview ?

Found this article :

http://www.knowdotnet.com/articles/sortedlistview.html

And I have followed the code on that to suit my needs so that I can load printer name, print job name and owner name into a listview and I have installed 2 fake printers and paused them both and send a print job to each and my code seems to work aside from one bug that I have noticed, if I take the lstJobs.List.Clear command out It works the first time I click the button but if I keep clicking it obviously keeps re adding it in and it duplicates itself, yet when I put it back into the code you only see one of the print jobs from one of the printers and not the other one.

Here is the code that I have so far ( Yes I have made a reference to the systems management ) :

Imports System
Imports System.Management

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim oq As New System.Management.ObjectQuery("SELECT * FROM Win32_PrintJob") '
        Dim query1 As New ManagementObjectSearcher(oq)
        Dim queryCollection1 As ManagementObjectCollection = query1.Get()
        Dim mo As ManagementObject
        For Each mo In queryCollection1
            Dim lvi As ListViewItem
            ' lstJobs.Items.Clear()
            With Me.lstJobs

                .Sorting = SortOrder.Ascending
                lvi = .Items.Add(mo("DriverName").ToString())
                lvi.SubItems.Add(mo("Document").ToString())
                lvi.SubItems.Add(mo("Owner").ToString())

                Me.Label1.Text = "ListItem(0).SubItems: " & .Items(0).SubItems.Count
            End With
        Next mo




    End Sub 'Main

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        lstJobs.Columns.Add("Printer", 200, HorizontalAlignment.Center)
        lstJobs.Columns.Add("Document", 200, HorizontalAlignment.Center)
        lstJobs.Columns.Add("Owner", 200, HorizontalAlignment.Center)
    End Sub
End Class

Hi gecko_au2003;

You have the Clear command in the For Each loop so every time it goes for the next item to put in the ListView control it clears it first. Place it befor the loop.
   
    lstJobs.Items.Clear()
