I have tried SaveR*FToStream and LoadR*VFromStream, but they did nothing.

Please help.

<<Below is source>>

unit Unit1;

interface

uses

  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

  Dialogs, StdCtrls, RVStyle, RVScroll, RichView, RVEdit;

type

  TForm1 = class(TForm)

    RichViewEdit1: TRichViewEdit;

    RVStyle1: TRVStyle;

    Button1: TButton;

    Button2: TButton;

    procedure FormCreate(Sender: TObject);

    procedure FormDestroy(Sender: TObject);

    procedure Button1Click(Sender: TObject);

    procedure Button2Click(Sender: TObject);

  private

    stream: TStream;

    { Private declarations }

  public

    { Public declarations }

  end;

var

  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);

begin

  stream := TMemoryStream.Create;

end;

procedure TForm1.FormDestroy(Sender: TObject);

begin

  stream.Free;

end;

procedure TForm1.Button1Click(Sender: TObject);

begin

  richviewedit1.SaveRVFToStream(stream,false);

end;

procedure TForm1.Button2Click(Sender: TObject);

begin

  richviewedit1.LoadRVFFromStream(stream);

  richviewEdit1.Format;

end;

end.
