le problème c'est tu effectues ce long traitement dans le thread principal.
Je te conseille de créer un nouveau thread qui fera ça en arrière plan, ca permettra à ton application de continuer à "vivre" normalement.

ok j'y connais rien en thread mais je vais essayer de m'y mettre
quelque chose me dit que je vais revenir poser des questions

sinon le fait que ça freeze dans le thread principale ça veut bien dire que quelque chsoe plante dans ma fonction qui envoi un message non? peut etre que je passe mal les parametres...
une idée?
