var

if not Shell_NotifyIcon(NIM_ADD, @IconData) then

end;

procedure TForm1.ShowBalloonTips;

end;

procedure TForm1.DeleteSysTrayIcon;

DeallocateHWnd(IconData.Wnd);
if not Shell_NotifyIcon(NIM_DELETE, @IconData) then
ShowMessage('delete fail');
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
AddSysTrayIcon;
ShowBalloonTips;
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
DeleteSysTrayIcon;
end;

end.

anyway i use more Cbuilder than Delphi

i´ve made a small component for it that works was a tray
icon and displays messages like:

Form1->MaDTrayIcon->ShowBalloonHint(AnsiString
Title, AnsiString Text, IconType, int duration);

tanks and sorry the bad inglish
