Thread: Memory Hacking with C and CheatEngine, writing to Process Memory

Learn to create a trainer (a program that writes to remote process memory) in C++ using a Calculator as an example. There are also references to cheat engine.

Source Code

#include <iostream>

#include <windows.h>

 

// FindWindow();

// GetWindowThreadProcessId();

// OpenProcess();

 

// WriteProcessMemory();

 

// CloseHandle();

 

using namespace std;

 

int main()

{

    int newValue = 500;

 

    HWND hWnd = FindWindow(0, "Calculator");

 

    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, &newValue, (DWORD)sizeof(newValue), NULL);

 

            if (isSuccessful > 0) {

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

            } else {

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

            }

 

            CloseHandle(hProc);

        }

    }

 

    return 0;
