🔍 Simple Memory Reading Writing 🔧

🔍 Very Simple Template to read / write Process Memory with C++ 🔧

🔍 Read Process Memory (ReadProcessMemory) 🔍

#include <iostream>
#include <Windows.h>
using namespace std;
int main(){
int readTest = 0; // We store the Value we read from the Process here
HWND hwnd = FindWindowA(NULL, "Tutorial-x86_64"); // HWND (Windows window) by Window Name
// Check if HWND found the Window
if (hwnd == NULL) {
cout << "Can't find Process." << endl;
Sleep(2000); // Sleep 2 seconds
exit(-1); // Exit the program if it did not find the Window
} else {
DWORD procID; // A 32-bit unsigned integer, DWORDS are mostly used to store Hexadecimal Addresses
GetWindowThreadProcessId(hwnd, &procID); // Getting our Process ID, as an ex. like 000027AC
HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, procID); // Opening the Process with All Access
if (procID == NULL) {
cout << "Can't find Process." << endl;
Sleep(2000); // Sleep 2 seconds
exit(-1); // Exit the program if it did not find the Window
} else {
// Read the Process Memory, 03007640 is the Address, we read the Value from and save it in readTest
ReadProcessMemory(handle, (PBYTE*)0x03007640, &readTest, sizeof(readTest), 0);
cout << readTest << endl;
Sleep(5000); // Sleep 5 seconds
}
}
}

🔧 Write into Process Memory (WriteProcessMemory) 🔧

#include <iostream>
#include <Windows.h>
using namespace std;
int main() {
int newValue = 5000; // The new Value we set on the address
HWND hwnd = FindWindowA(NULL, "Tutorial-x86_64"); // HWND (Windows window) by Window Name
// Check if HWND found the Window
if (hwnd == NULL) {
cout << "Can't find Process." << endl;
Sleep(2000); // Sleep 2 seconds
exit(-1); // Exit the program if it did not find the Window
}
else {
DWORD procID; // A 32-bit unsigned integer, DWORDS are mostly used to store Hexadecimal Addresses
GetWindowThreadProcessId(hwnd, &procID); // Getting our Process ID, as an ex. like 000027AC
HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, procID); // Opening the Process with All Access
if (procID == NULL) {
cout << "Can't find Process." << endl;
Sleep(2000); // Sleep 2 seconds
exit(-1); // Exit the program if it did not find the Window
}
else {
// Write the newValue into the Process Memory, 03007640 is the Address
WriteProcessMemory(handle, (PBYTE*)0x03007640, &newValue, sizeof(newValue), 0);
Sleep(5000); // Sleep 5 seconds
}
}
