Need Help Making my first Hack!!
Hello MPGH,
I watched a tutorial on Youtube about memory hacking using c++ . I tried making a hack for MW3, but get alot of errors in cout, cerr, clog and some other stuff, Please help me @Jorndel @master131 and anyone who can help. Thanks Im waiting for your reply ppl.

 
Source Code
Code:
#include <iostream>
#include "stdafx.h"
#include <windows.h>
#include <stdio.h>

 

// FindWindow();
// GetWindowThreadProcessId();
// OpenProcess();
// WriteProcessMemory();
// CloseHandle();

 

using namespace std;

 

int main()

{

    int Score;
	cout<<"Welcome to oTrainer v1 @MPGH.net \n";
	cout<<"Features: \n";
	cout<<"Score Hack \n";
	cout<<"Enter the Score you want:   ";

	cin>> Score;
	cin.ignore();

    HWND hWnd = FindWindow(0, "Call of Duty®: Modern Warfare® 3 Multiplayer");
	
 

    if (hWnd == 0) {

        cerr << "Cannot find window." << endl;

    } else {

        DWORD pId;

        GetWindowThreadProcessId(hWnd, &pId);

        HANDLE hProc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pId);

 

        if (!hProc) {

            cerr << "Cannot open process." << endl;

        } else {

            int isSuccessful = WriteProcessMemory(hProc, (LPVOID)0x000AFCC4, &Score, (DWORD)sizeof(Score), NULL);

 

            if (isSuccessful > 0) {

                clog << "Process memory written." << endl;

            } else {

                cerr << "Cannot write process memory." << endl;

            }

 

            CloseHandle(hProc);

        }

    }



    return 0;

}

Erm, you sure you use right debugger ?
(Not Visual Studio etc)

I might look on it, when I'm done playing

I used: Dec-C++
Here is the code that I used based on yours: (Works)
Code:
#include <cstdlib>
#include <iostream>
#include <windows.h>
#include <stdio.h>

using namespace std;

int main(int argc, char *argv[])
{
    int Score = 3;
    HWND hWnd = FindWindow(0, "Call of Duty®: Modern Warfare® 3 Multiplayer");
    if (hWnd == 0) {

        cerr << "Cannot find window." << endl;

    } else {

        DWORD pId;

        GetWindowThreadProcessId(hWnd, &pId);

        HANDLE hProc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pId);

 

        if (!hProc) {

            cerr << "Cannot open process." << endl;

        } else {

            cerr<<"Set your Score: ";
            cin>>Score;
            int isSuccessful = WriteProcessMemory(hProc,(LPVOID)0x1DB8BD0,&Score,sizeof(Score),NULL);

 

            if (isSuccessful > 0) {

                clog << "Process memory written." << endl;

            } else {

                cerr << "Cannot write process memory." << endl;

            }

 

            CloseHandle(hProc);

        }

    }
    system("PAUSE");
    return EXIT_SUCCESS;
}


Mostly like that |Microsoft Visual C++ 2010 Express| caused the problems here :|
