rkfr.SetValue("fontname", RichTextBox1.Font.Name.ToString)
      rkfr.SetValue("fontsize", Double.Parse(RichTextBox1.Font.Size))
      rkfr.SetValue("fontstyle", RichTextBox1.Font.Style)

RichTextBox1.Font = New Font(rkfr.GetValue("font").ToString, _
      Double.Parse(rkfr.GetValue("fontsize")), rkfr.GetValue("fontstyle"))
