systray menu

Bonjour,

Je suis en train de faire un menu qui apparaitra dans la barre des
taches.
Ca marche plutot bien sauf que :

1 - l'ic=F4ne n'apparait pas m=EAme si l'emplacement est disponible et que
les actions de la souris y sont disponnibles. Tout ce passe comme si
l'application ne trouvait pas le visuel de l'ic=F4ne.

2 - j'ai mis une action close qui appelle DestroyMenu(hmenu); Elle
marche et fait disparaitre le menu, mais en suite il n'est plus
disponible.

Je suis sous xp familial.

Voici le code source complet, cr=E9=E9 en partie par le appwizard :

#include "stdafx.h"
#include "neurocom.h"
#include "shellapi.h"
