Как получить картинки из MessageDlg?

Code:

procedure TForm1.Button1Click(Sender: TObject);

var

Ic: TIcon;

begin

Ic := TIcon.Create;

Ic.Handle := LoadIcon(0, IDI_APPLICATION);

Form1.Canvas.Draw(1, 1, Ic);

Ic.Handle := LoadIcon(0, IDI_ASTERISK);

Form1.Canvas.Draw(32, 1, Ic);

Ic.Handle := LoadIcon(0, IDI_EXCLAMATION);

Form1.Canvas.Draw(64, 1, Ic);

Ic.Handle := LoadIcon(0, IDI_QUESTION);

Form1.Canvas.Draw(1, 32, Ic);

Ic.Handle := LoadIcon(0, IDI_HAND);

Form1.Canvas.Draw(32, 32, Ic);

Ic.Handle := LoadIcon(0, IDI_WINLOGO);

Form1.Canvas.Draw(64, 32, Ic);

Ic.Destroy;

end;
