ERREUR: Échec de vérification de l'exécution # 2 - La pile autour de la variable 'fichier' a été corrompue

using namespace std; 

const int file_l = 100;

int main()

} 

ci-dessus est mon code. Je suis un débutant. Programmation C++, en utilisant Visual Studio 2010

Je continue à avoir l'erreur: «d'exécution Échec de la vérification # 2 - Stack autour de la variable « fichier » a été corrompu »
ce que je pensais que je ne devrais pas faire le "* char fichier [file_l]; *" la même longueur que les autres, donc je l'ai changé pour "* fichier char [fichier_l + 1]; " Apparemment, le problème a résolu, plus d'erreur. Pourriez-vous s'il vous plaît laissez-moi savoir si c'est la bonne façon de corriger cette erreur?

En outre, le programme n'a pas imprimer tout le code HTML de la page Web dans le fichier "" Summer Research tests.txt "*" comme je le voulais. il n'a pas imprimé à partir de la ligne 1 et a toujours arrêté à la ligne 209. J'ai changé les choses, mais très peu de progrès. aidez s'il vous plaît.

Toute aide est grandement appréciée!

Answer 1

Copier de mes commentaires au message d'origine:
file [read] = '\ 0'; provoquera un comportement indéfini si read == 100 puisque vous accédez 1 après la fin du tableau de fichiers. Votre solution pour ce correct:

char file[file_l+1]; 

Pour le problème de sortie:
vous terminez d'utiliser la première lecture toujours en ne délivrant ce qui était dans le fichier avant que la boucle while et aussi ne montre pas ce qui était dans le tableau de fichiers sur le dernière lecture si la taille de lecture n'était pas de 100 octets.

Pour résoudre ce problème, je réécris votre boucle while un peu:

InternetReadFile(hURL, file, file_l, &read); 
while (read > 0) 
{ 
    // Something was read we should output it now! 
    file[read] = '\0'; 
    cout << file; 
    fout << file; 
    InternetReadFile(hURL, file, file_l, &read); 
} 

En déplaçant le deuxième InternetReadFile() pour après le code qui les délivre nous se ne jeter la première lecture sans délivrer en sortie. Aussi j'ai changé la comparaison pour lire> 0 pour résoudre 2 problèmes: Les lectures de moins de 100 octets et la lecture finale.

J'ai inclus les corrections dans mes modifications apportées à votre code ici:

#include <string> 
#include <iostream> 
#include <fstream> 
#include <windows.h> 
#include <wininet.h> 
#include <winsock.h>

{ 
    HINTERNET hOpen, hURL; 
    LPCWSTR NameProgram = L"Webreader";    //LPCWSTR == Long Pointer to Const Wide String 
    LPCWSTR Website;      
    char file[file_l+1]; // Add an additional character for '\0' 
    unsigned long read; 

    //Always need to establish the internet connection with this function. 
    if (!(hOpen = InternetOpen(NameProgram, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0))) 
    { 
     cerr << "Error in opening internet" << endl; 
     return 0;

    ofstream fout("Summer Research testing.txt"); 

    InternetReadFile(hURL, file, file_l, &read); 
    while (read > 0)

Answer 2

lire ne devrait jamais être> = file_l! Cela signifie que vous devez écrire

while (read == file_l - 2) 

et

file[read-1] = '\0'; 

(file_l - 2 parce que le dernier octet doit être réservé pour « \ 0 ») J'espère que vous vous rendez compte que la boucle while vos déclarations seulement si le tampon "read" (qui devrait être de type LPVOID et non char *) est plein. Par ailleurs, votre application est presque entièrement écrite en C, pas en C++.
