This code does not drag anything:

Private Sub clsTVItemDrag(ByVal sender As Object, ByVal e As
System.Windows.Forms.ItemDragEventArgs) Handles Me.ItemDrag
    Dim n As TreeNode = DirectCast(e.Item, TreeNode)
    Dim filePaths(0) As String
    Dim DragDropEffect As DragDropEffects
    Dim data As DataObject

    filePaths(0) = n.Name

    If filePaths.Length > 0 Then
      data = New DataObject(Windows.Forms.DataFormats.FileDrop, filePaths)

      DragDropEffect = Me.DoDragDrop(data, DragDropEffects.Copy Or
      If _HighlightedNode Is Nothing = False Then
        _HighlightedNode.BackColor = System.Drawing.Color.White
      End If
      If DragDropEffect = DragDropEffects.Move Then
        RaiseEvent DeleteFiles(n, New DeleteFilesEventArgs(filePaths))

      End If
    End If
  End Sub
