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

Ce n'est pas du VB6, mais l'unité AviCap.pas en Delphi
Ca peut aider

Code:
