Hi,
here below i have a code.
It reads a line from a text file and then it takes that line to other function (DescargarUrl()).
"DescargarUrl()" prints the line that was readen previously from the text file.
The problem:
depending in the order of the lines 94 y 95 it prints correctly the line that was readen from the text file or not. why?
I mean:
this prints ok the line
this doesn't print ok the line:Code:line 94: printf("DescargarUrl: %s \n", Url); line 95: CInternetSession SesionInternet;
Code:line 94: CInternetSession SesionInternet; line 95: printf("DescargarUrl: %s \n", Url);RegardsCode:// p4_OK.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include "p4_OK.h" #ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__; #endif ///////////////////////////////////////////////////////////////////////////// // The one and only application object CWinApp theApp; int Principal(); using namespace std; int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]) { int nRetCode = 0; // initialize MFC and print and error on failure if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0)) { // TODO: change error code to suit your needs cerr << _T("Fatal Error: MFC initialization failed") << endl; nRetCode = 1; } else { Principal(); } return nRetCode; } char * ExtraerParametros() { char nombre[100]="C:\\Archivos de programa\\Microsoft Visual Studio\\MyProjects\\p3\\ordenes.txt"; FILE *fichero; fichero = fopen( nombre, "r" ); char cad[3]="#\n"; char linea_ord[1000]; fread( linea_ord, sizeof(char), 1000, fichero ); printf ("Los parametros de la linea de comandos de ordenes.txt son los siguientes: \n\n"); printf ("- Primera URL: "); char *ptr; ptr = strtok(linea_ord , cad ); // Primera llamada => Primer token printf( "%s\n", ptr ); char * ptr2; ptr2=ptr; printf("- Segunda URL (archivos a descargar): "); ptr = strtok( NULL, cad ); printf( "%s\n", ptr ); fclose(fichero); return ptr2; } char * DescargarUrl(char * Url, int * Error, long * Tamanyo) { printf("DescargarUrl: %s \n", Url); CInternetSession SesionInternet; // Abrir una sesion de Internet char *a=NULL; return a; } int Principal() { char nombre_img[100]="C:\\Archivos de programa\\Microsoft Visual Studio\\MyProjects\\p3\\imagen.jpg"; FILE *fichero_img; fichero_img = fopen( nombre_img, "w+" ); char * URL1; char * Fichero = NULL; int Error = 0; long Tamanyo = 0; URL1 = ExtraerParametros(); Fichero = DescargarUrl(URL1, &Error, &Tamanyo); return 0; }
