Как сделать так, чтобы запущенная программа не была видна на панели задач?

type
  TForm1 = class(TForm)
    Label1: TLabel;
    RxTrayIcon1: TRxTrayIcon;
    procedure FormCreate(Sender : TObject);
    procedure RxTrayIcon1DblClick(Sender: TObject);
  private
    { Private declarations }
    procedure ApplicationMinimize(Sender : TObject);
    procedure ApplicationRestore(Sender : TObject);
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.FormCreate(Sender: TObject);
begin
Application.OnMinimize := ApplicationMinimize;
Application.OnRestore := ApplicationRestore;
ShowWindow(Application.Handle, SW_HIDE);
end;

procedure TForm1.ApplicationMinimize(Sender : TObject);
begin
ShowWindow(Application.Handle, SW_HIDE);
end;

procedure TForm1.ApplicationRestore(Sender : TObject);
begin
ShowWindow(Application.Handle, SW_HIDE);
end;

procedure TForm1.RxTrayIcon1DblClick(Sender: TObject);
begin
Application.Restore;
Application.BringToFront;
end;
