{
    // Make sure there is text.
    if (e.Result.Lines.Count == 0)
    {
        tbResults.Text = "No text found.";
        return;
    }

    // Read the text and print it to a TextBlock.

    foreach (Line l in e.Result.Lines)
    {
        foreach (Word w in l.Words)
        {
            sb.AppendFormat("{0} ", w.Value);
