    Bonjour,

    Suite à mon précédent post: http://www.developpez.net/forums/sho...d.php?t=552899

    J'ai voulu créer un programme sous visual studio 2008 avec des windows form application me permettant de gérer les 2 moteurs.
    Cependant j'ai des erreurs, et je ne sais pas comment les corriger:

    Voici mon programme form.h:
    #pragma once
    #include "stdafx.h"
    #include "Form1.h"
    #include "E:\Stage_robot\Stepper Bee +\stp.h" // rename the header file

    Je ne comprend pas mes erreurs car comme vous pouvez le voir sur le précédent post, en win32 application tous fonctionner correctement.

    Merci d'avance

    ps: désolé pour la longueur du message mais je n'arrivais pas à l'éditer autrement.

    Bonjour.

    Il semblerait que tu déclares les valeurs de "InitStp, RunMotor1, etc..." dans le fichier robot_control_ER1.cpp. Le fichier "form.h", ne peut pas connaître ces valeurs.

    Toute valeur déclarée dans un .cpp ne peut pas être connue par un .h.

    Plusieurs possibilités, par exemple, avec un .h :

    Code : Sélectionner tout - Visualiser dans une fenêtre à part
    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
     
 
// global.h
 
extern Type_InitStp InitStp;
extern Type_RunMotor1 RunMotor1;
extern Type_StopMotor1 StopMotor1;
extern Type_RunMotor2 RunMotor2;
extern Type_StopMotor2 StopMotor2;
extern Type_SetStepMode SetStepMode;
extern Type_GetCurrentStatus GetCurrentStatus;
    Ensuite inclure ce fichier dans "form.h".

    Dans la FAQ C++, tu dois avoir quelques renseignements sur le bon usage des fichiers d'en-tête. Un petit tour serait le bienvenu.
