    Par défaut les paramètres de "AVICAP32.dll"
    Bonjour à tous.
    J'aimerai bien comprendre le sens des paramètres à inclure dans la déclaration et l'utilisation de "AVICAP32.dll". Y a t'il un tuto, ou une documentation qui explique leur utilisation.
    Merci d'avance.

    Bonjour,
    Il semble qu'Avicap32 ne soit pas documenté, il va donc falloir aller à la pêche.
    Par exemple avec http://social.msdn.microsoft.com/Sea...=avicap32&ac=8
