Problème avec timer

Bonjour,

Le programme vise à gérer une pédale et qu'elle puisse être à nouveau détectée si on venait à la débrancher puis à la rebrancher.
Voici le main :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

int _tmain(int argc, _TCHAR* argv[]) {   //log(WITH_TIME, SCORE_CLASS_INSTANTIATION); static score& My_Score = score::getInstance();   pedal My_Pedal;   My_Pedal.enumerate_pedal();   if (My_Pedal.search_pedal_port()) My_Pedal.activate_pedal();   //My_Pedal.enumerate_pedal();   Jeu jeu; jeu.executer();   //My_Score.execute(); //My_Score.parse(XmlFilename);   std::cin >> key;   My_Pedal.deactivate_pedal();   return 0; }

Et voici la classe pedal : le header :

En l'état, enumerate ne fait rien hormis d'afficher un message toutes les 2 secondes.
Il y a une séquence d'initialisation de la pédale et si OK alors on vient interroger par timer la pédale toutes les 200 ms avec une attente de données de 20 ms.
Tout cela fonctionne à merveille.
Maintenant je souhaiterais déplacer :

Code:

---

1 2	if (My_Pedal.search_pedal_port()) My_Pedal.activate_pedal();

---

pour le mettre dans enumerate.

Si je fais celà, le timer initialisé par wait_for_reply() ne se lance pas et donc je boucle dans le premier while de la méthode search_pedal_port().
Je ne comprends pas pourquoi ....


Un tout petit peu d'aide serait bienvenue ... Merci
