Bonjour tout le monde
Voila j'ai un probleme avec un programme de reconnaissance vocal en C#
J'ai fais comme dans le tuto microsoft mais le problème est que quand je dit lecture il me synthétise le texte
mais après le programme plante et il me dit :
"La référence d'objet n'est pas définie à une instance d'un objet"
voir miniatures en dessous !
Voila tout le code de applications :
Merci d'avance pour l'aideCode:
