How to refresh listview without loosing selected item?

I have searched google but no luck.... :(

I am creating a process explorer like application in visual studio 2005 (vb.net)
and when i click the refresh button my current selected is gone, now i dont know how to keep the selected item even i click the refresh button
here is my code for the listview:

'list all processes in to a listview

Private Sub ListProcesses()
      Dim ps() As Process
      Try
          ps = Process.GetProcesses()
          lvProcesses.BeginUpdate()
          lvProcesses.Clear()
          lvProcesses.Columns.Add("Name", 100, HorizontalAlignment.Left)
          lvProcesses.Columns.Add("ID", 60, HorizontalAlignment.Left)
          lvProcesses.Columns.Add("Priority", 60, HorizontalAlignment.Right)
          lvProcesses.Columns.Add("Memory(bytes)", 100, HorizontalAlignment.Right)
          Dim p As Process
          For Each p In ps
              Dim lvi As ListViewItem = New ListViewItem()
              lvi.Text = p.ProcessName
              lvi.SubItems.Add(p.Id.ToString())
              lvi.SubItems.Add(p.BasePriority.ToString())
              lvi.SubItems.Add(p.WorkingSet64.ToString())
              lvProcesses.Items.Add(lvi)
          Next p
          lvProcesses.EndUpdate()
      Catch e As Exception
          MessageBox.Show(e.Message)
      End Try
  End Sub

'refreshbtn

ListProcesses()

Dim selectedit As String
selectedit = lvProcesses.SelectedItems(0).Text
Me.lvProcesses.Items(selectedit).Selected = True

'listview
'selected item @ listview

lvProcesses.SelectedItems(0).SubItems(0).Text
