Bonjour,

je cherche à realiser un prgramme C++ qui réalise un screenshot toutes les x millisecondes.

j'ai récupéré le code d'un "timer", mais je n'arrive pas à compiler.

Si qqun a une idée, je suis preneur !

Merci d'avance !

Voici le code :

Screenshot.cpp

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

#include <iostream>
#include "Timer.cpp"
 
using namespace std;
 
int main() {
 
	Timer timer;
	int repetitions = 0;
 
 
	timer.start();
 
	while (repetitions < 100) {
 
		if (timer.getTime() >  500) {
 
			cout << "Répétition n°" << repetitions << endl;
			timer.reset();
			repetitions ++;
		}
 
 
 
	}//Fin boucle
 
	timer.stop();
 
	return 0;
}

Timer.cpp

	resetted = true;
	beg = 0;

}

	return running;
}

	if(running)
		return ((unsigned long) clock() - beg) / CLOCKS_PER_SEC;
	else
		return end - beg;
}
 
 
bool Timer::isOver(unsigned long seconds) {
	return seconds >= getTime();
}

	unsigned long beg;
	unsigned long end;
 
};
 
#endif /* TIMER_H_ */

Et Voici l'erreur que j'obtiens :
