Bonjour, ayant eu des problèmes sur un programme pour faire avancer une progressbar j'ai voulu faire un programme de test, mais problème dans celui ci je n'arrive pas à créer la barre de progression.
Le code d'erreur est 1407 (impossible de trouver la classe de fenetre).
Je ne vois pas ce que j'aurais pu oublier.
Mon code
#include <windows.h>
#include <stdio.h>
#include "main.h"
#include <commctrl.h>
