minimize to tray

I am trying to make my application run only in the system tray.  I have it set to hide when minimized but it only works once.  The hide seems to have no effect the second time.

I am using the trayicon component and applicationevents component of Delphi 2009 running on WindowsVista
procedure Ttcau.ApplicationEvents1Minimize(Sender: TObject);
begin
  hide;
end;
 
procedure Ttcau.ApplicationEvents1Restore(Sender: TObject);
begin
  show;
  bringtofront;
end;
 
procedure Ttcau.TrayIcon1DblClick(Sender: TObject);
begin
 if visible then
   begin
     application.Minimize;
     hide;
   end
     else
    begin
      application.Restore;
      show;
      application.bringtofront;
    end;
 end;

you'll need to remember the state of the application too in a separate variable
there is different places the form can be hidden or closed ...

this adds a menu option to the TrayIcon1 to close the application

Hitting the close button of the form, minimizes it to the tray
type
  TForm1 = class(TForm)
    TrayIcon1: TTrayIcon;
    PopupMenu1: TPopupMenu;
    popCloseApplication1: TMenuItem;
    procedure TrayIcon1DblClick(Sender: TObject);
    procedure FormCloseQuery(Sender: TObject; var CanClose: Boolean);
    procedure popCloseApplication1Click(Sender: TObject);
  private
    fAppVisible: Boolean;    
    fAppClosing: Boolean;
  public
    constructor Create(AOwner: TComponent); override;
  end;
 
constructor TForm1.Create(AOwner: TComponent);
begin
  inherited Create(AOwner);
  fAppVisible := True;
  fAppClosing := True;
end;
 
procedure TForm1.FormCloseQuery(Sender: TObject; var CanClose: Boolean);
begin
  CanClose := fAppClosing;
  if not CanClose then
  begin
    Hide;
    fAppVisible := False;
  end;
end;
 
procedure TForm1.TrayIcon1DblClick(Sender: TObject);
begin
  if not fAppVisible then
  begin
    Self.Show;
    Self.BringToFront;
  end else
  begin
    Self.Hide;
  end;
  fAppVisible := not fAppVisible;
end;
 
procedure TForm1.FormCloseQuery(Sender: TObject; var CanClose: Boolean);
begin
  CanClose := fAppClosing;
  if not CanClose then
  begin
    Hide;
    fAppVisible := False;
  end;
end;
 
procedure TForm1.popCloseApplication1Click(Sender: TObject);
begin
  fAppClosing := True;
  Close;
end;

It worked except I needed to change:

constructor TForm1.Create(AOwner: TComponent);
begin
  inherited Create(AOwner);
  fAppVisible := True;
  fAppClosing := False;
end;

Thank you very much!
