How to put an icon into the tray

This may be really easy, but I am looking for a way to put an icon into the tray (95/98/NT) when my program is running and not have it appear on the task bar.  Any clues?

here an example for a animated icon in the tray:

const
  WM_MYTRAYICONCALLBACK = WM_USER + 1000;

type
  TForm1 = class(TForm)
    PopupMenu1 : TPopupMenu;
    Close1     : TMenuItem;
    Restore1   : TMenuItem;
    Timer1     : TTimer;
    procedure Close1Click(Sender: TObject);
    procedure Restore1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
    procedure Timer1Timer(Sender: TObject);
  private
    { Private declarations }
    HIcon1, HIcon2 : HICON;
    MyTrayIcon: TNotifyIconData;
    procedure AppMinimize(Sender:TObject);
    procedure WMMyTrayIconCallback(var Msg:TMessage);
                       message WM_MYTRAYICONCALLBACK;
  public
    { Public declarations }
  end;

{...}

procedure TForm1.FormCreate(Sender: TObject);
begin
  { load our icons }
  HIcon1 := LoadIcon(0, IDI_WINLOGO);
  HIcon2 := LoadIcon(0, IDI_HAND);

  { set TApplictaion.OnMinimize to our new event }
  Application.OnMinimize := AppMinimize;

  { start our application minimized to the System Tray }
  Visible := FALSE;
  Application.ShowMainForm := Visible;

  { required to set cbSize to SizeOf our structure }
  MyTrayIcon.cbSize := SizeOf(TNotifyIconData);

  { handle to main window }
  MyTrayIcon.Wnd    := Handle;

  { identifier of our icon }
  MyTrayIcon.uId    := 1;

  { flags showing what we are using in the other members below }
  MyTrayIcon.uFlags := NIF_ICON or NIF_TIP or NIF_MESSAGE;

  { our user defined message }
  MyTrayIcon.uCallBackMessage := WM_MYTRAYICONCALLBACK;

  {  set our icon to the first one loaded above }
  MyTrayIcon.hIcon  := HIcon1;

  { help message of the icon }
  MyTrayIcon.szTip  := 'Lou''s Delphi Tip of the Day [MyTrayIcon]';

  { add our icon to the tray }
  Shell_NotifyIcon(NIM_ADD, @MyTrayIcon);
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
  { remove our icon from the tray }
  Shell_NotifyIcon(NIM_DELETE, @MyTrayIcon);
end;

procedure TForm1.AppMinimize(Sender:TObject);
begin
  { hide our application }
  Visible := FALSE;
  Application.ShowMainForm := Visible;
end;

procedure TForm1.WMMyTrayIconCallback(var Msg:TMessage);
var
  CursorPos : TPoint;
begin
  case Msg.lParam of
    WM_LBUTTONDOWN :
      begin
        { get mouse cursor position }
        GetCursorPos(CursorPos);
        { popup our TPopupMenu }
        PopupMenu1.Popup(CursorPos.X,CursorPos.Y);
      end;
  end;
end;

procedure TForm1.Close1Click(Sender: TObject);
begin
  { close our application }
  Close;
end;

procedure TForm1.Restore1Click(Sender: TObject);
begin
  { restore our application, or minimize if already
    in a restore mode }
  Visible := TRUE;
  Application.ShowMainForm := Visible;
  SetForegroundWindow(Application.Handle);
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  { change our icon to the opposite one loaded }
  if MyTrayIcon.hIcon = HIcon1 then
    MyTrayIcon.hIcon := HIcon2
  else
    MyTrayIcon.hIcon := HIcon1;

  { tell the SystemTray to modify our changes }
  Shell_NotifyIcon(NIM_MODIFY, @MyTrayIcon);
end;

Perhaps I am doing something wrong.  Got to ftp://ftp.cdrom.com/pub but there wasn't anything in delphi_www and the full path of each of these was unavailable.

devgr is for delphi 2, and it doesn't include the code only the dcu.  I'm looking for how to do it.  I will wait a few hours and try to get into the htp you reccomended.

Sorry, I am still unable to access the sites other than the one that has no source and is for delphi 2.  Perhaps I can get another answer.

I think you know how to add icon to the tray (from Raymond's suggestion)

All you want know now is "how we can hide a program from TaskBar?", right?

This is a command to hide program from Taskbar.

  ShowWindow(Application.Handle,SW_HIDE);

and this is a command to show them again
  ShowWindow(Application.Handle,SW_SHOW);
