    Name: String;

    CheckpointData: TCheckpointData;

    RaiseEvent: Boolean;

    s: String;

begin

  MyListBox.Items.Clear;

  CheckpointData := MyRichView.GetFirstCheckpoint;

  while CheckpointData<>nil do 

  begin

    MyRichView.GetCheckpointInfo(CheckpointData, Tag, Name, RaiseEvent);

    s := Format('Name:"%s" Tag:"%s"', [Name, Tag]);

    MyListBox.Items.Add(s);

    CheckpointData := MyRichView.GetNextCheckpoint(CheckpointData);

  end;
