{
    System.IO.FileStream streamR = new System.IO.FileStream(System.Windows.Forms.Application.StartupPath + "\\sample.rtf", System.IO.FileMode.Open);
    rtfRTF.Load(streamR, RichTextType.Rtf);

    System.IO.FileStream streamH = new System.IO.FileStream(System.Windows.Forms.Application.StartupPath + "\\sample.html", System.IO.FileMode.Open);
    rtfHTML.Load(streamH, RichTextType.Html);
}
Private Sub Detail_Format(ByVal sender As Object, ByVal e As System.EventArgs) Handles Detail.Format
    Dim streamR As New System.IO.FileStream(Application.StartupPath & "\sample.rtf", IO.FileMode.Open)
    rtfRTF.Load(streamR, RichTextType.Rtf)
