Dim FD As OpenFileDialog = New OpenFileDialog()
FD.Filter = "Journal files(*.jnt)|*.jnt"
If FD.ShowDialog() = Windows.Forms.DialogResult.OK Then
    Dim jntStream As Stream = Nothing
    Dim xmlStream As Stream = Nothing
    Try
        jntStream = FD.OpenFile()
        If Not IsNothing(jntStream) Then
            xmlStream = JournalReader.ReadFromStream(jntStream)
            Dim xmlDoc As XmlDocument = New XmlDocument()
            xmlDoc.Load(xmlStream)
            Dim xmlTW As XmlTextWriter = New XmlTextWriter(Console.Out)
            xmlTW.Formatting = Formatting.Indented
            xmlDoc.WriteTo(xmlTW)
            xmlTW.Flush()
        End If

    Catch ex As Exception
        ' handle exception
    Finally
        If Not IsNothing(jntStream) Then
            jntStream.Close()
        End If
        If Not IsNothing(xmlStream) Then
            xmlStream.Close()
        End If
    End Try

End If

OpenFileDialog FD = new OpenFileDialog();
FD.Filter = "Journal files(*.jnt)|*.jnt";
if (FD.ShowDialog() == DialogResult.OK)
{
    Stream jntStream = null;
    Stream xmlStream = null;
    try
    {
        if ((jntStream = FD.OpenFile()) != null)
        {
            xmlStream = JournalReader.ReadFromStream(jntStream);
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(xmlStream);
            XmlTextWriter xmlTW = new XmlTextWriter(Console.Out);
            xmlTW.Formatting = Formatting.Indented;
            xmlDoc.WriteTo(xmlTW);
            xmlTW.Flush();
        }
    }
    catch
    {
        // handle exception
    }
    finally
    {
        if (null != jntStream) { jntStream.Close(); }
        if (null != xmlStream) { xmlStream.Close(); }
    }
