In my project I want to load a jpg image from file, but the result always is 0x0000000. i have tried more than more. if anyone knows what is the problem please tell me.

i have used:

#include <string>
#include <gdiplus.h>
#include <iostream>

using namespace std;
using namespace Gdiplus;

#pragma comment(lib,"GdiPlus.lib")

and my code is :

    wifstream infile("jpgfiles.txt")
while(!infile.eof()){

    WCHAR _file[MAX_PATH];

    infile.getline(_file,MAX_PATH,'\n');


    Bitmap* gpBitmap = new Bitmap(_file);
            int e = GetLastError();
            char num1[10];
            itoa(e,num1,10);
            MessageBoxA(0,num1,"error",MB_OK);
    }

the messagebox always prints 0 and gpBitmap is 0x00000000.
thank you.
