Disque tutorial para el contador

Paso 1

Primero que nada quitas el todo esa cosa fea

Luego agregas un botón, te debe de quedar así :

Paso 2

Luego te metes al dlg.h

Para agregar 2 variables, son las de la foto

public:

int m_conteo;

int m_num;

paso 3

agregas el timer,

nadamas sigue los pasos de estas fotos:

Le picas al botoncillo ese que le puse la flecha amarilla luego pues te sale el menú ese de la siguiente foto, buscas el que dice WM_TIMER le picas a su caja, y le picas en add ontimer (así decía, pero pues es que en la foto pues ya se lo puse)

Luego ya te vas al archivo de .cpp

Y en ese borras todo el código y copias el código siguiente, (si tu programa tiene otro nombre, asegúrate de cambiar el MFCApplication3 por el nombre de tu archivo, cambiarlo en todas las partes del código donde lo veas, para que funcione bien tú código
