Bonjour à tous,
Je souhaite utiliser une DLL fournie par GFLSDK, mais j'ai quelques soucis dans la déclaration de mes structures, ce qui me déclenche des "Fatal Error". Je ne sais pas trop quels types de données je dois déclarer. D'après l'aide fournie par GFL, pouvez-vous m'indiquer le code correspondant pour déclarer la structure sous WD ?
Merci d'avance !
Grum.
