        dialogOpenFiles.Filter = "All Files (*.*)|*.*"

        If dialogOpenFiles.ShowDialog Then
            Dim i As String
            For Each i In dialogOpenFiles.FileNames
                Dim s() As String = i.Split("\")
                For j As Integer = 0 To UBound(s)
                    If j = 8 Then
                        'Me.ListBox1.Items.Add(s(8))
                    ElseIf j = 7 Then

                        'Me.ListBox2.Items.Add(s(7))
                    ElseIf j = 6 Then

                        'Me.ListBox3.Items.Add(s(6))
                    ElseIf j = 5 Then
