Hello,
I want to read memmory with pointer, me code without pointers:
| Code: |
#include <windows.h>
#include <iostream>
int main()
{
SetConsoleTitle ("Test");
DWORD processId;
HANDLE hProcess;
DWORD address = 0x000AA768;
processId = 6336;
hProcess = OpenProcess(PROCESS_ALL_ACCESS, false, processId);
int value;
ReadProcessMemory(hProcess, (LPVOID)address, &value, 4, 0);
std::cout<<"Value:"<<value<<std::endl;
return 0;
}
|
Cheat engine:
"game.exe"+00EE1C00
pointer = 320
so "game.exe"+00EE1C00+320 = address
how to get full address with ponter?

Pointer: "game.exe"+00EE1C00
Offset1: 320
| Code: | DWORD Pointer, Offset1, Resultado;
Pointer = ((DWORD)GetModuleBaseAddress(processId , "game.exe") + 0x00EE1C00);
printf("Pointer: 0x%08X \n", Pointer);
ReadProcessMemory(hProcess, (void*)Pointer, &Offset1, 4, NULL);
Offset1 += 0x320;
printf("Offset1: 0x%08X \n\n", Offset1);
ReadProcessMemory(hProcess, (void*)Offset1, &Result, 4, NULL);
printf("Result: %i \n\n", Result); |

| Code: | template <class T>
void read(DWORD addy, T& var) {
ReadProcessMemory(m_prcHndl, (LPCVOID)addy, &var, sizeof(var), NULL);
}
template <class T>
T read(DWORD addy) {
T temp;
ReadProcessMemory(m_prcHndl, (LPCVOID)addy, &temp, sizeof(temp), NULL);
return temp;
}
template <class T>
void readPtr(int numOfOffsets, DWORD offsets[], DWORD base, T& var) {
DWORD temp = read<DWORD>(base);
int i;
for (i = 0; i < numOfOffsets - 1; i++) {
temp = read<DWORD>(temp + offsets[i]);
}
read<T>(temp + offsets[i], var);
} |
Just a snip from my simple memory class. Pseudo code for the usage:
| Code: | DWORD address = 0xDEADBEEF;
DWORD offsets[] = { 0xFE, 0xBE, 0xAD, 0xDE };
DWORD result;
readPtr<DWORD>(4, offsets, address, result); |
Good luck,
Krampus

The code in the first post worked. I just don't want to search for the PID every time I restart the game.
1. How to grab PID from active window?
2. How to grab all PIDs from programs with certain window title?
I tried #1, but this code seems to be giving me random numbers (The PIDs I get do not match any process in my task manager). Each run gives a different result, even though cmd.exe window is focused every time.
read_test3.cpp
| Code: |
#include <iostream>
#include <string>
#include <windows.h>
int main()
{
int pid = GetCurrentProcessId();
std::cout<< pid << "\n\n\n\n\n\n\n\n\n";
return 0;
} |
PS I'm fairly new in c++. Seems odd that I can't even add "sleep 2000;" in there w/o compiling errors.

You get a different PID because the executable is a different process than your command prompt.
If you look in your Task Manager, you'll notice cmd.exe is there and when you run your test, read_test3.exe pops up briefly.
Same can also be true for some games. The process you attach isn't necessarily the window.
To find the PID of a window, you can use:
| Code: | HWND WindowHandle = FindWindow(nullptr, L"Window Title");
DWORD PID;
GetWindowThreadProcessId(WindowHandle, &PID);
PVOID hProcess = OpenProcess((0x0010) | (0x0400), 0, PID); |
You should have access to "Sleep(2000)" since you included <Windows.h>.
I do believe it needs to be capitalized.

If you want to get the active / foreground window there is:
- GetForegroundWindow
If you want to find all windows matching the same name, you can use:
- FindWindow
- GetWindow
You would call FindWindow with the name of the window title or class name you wish to look for, then inside of a loop you would call GetWindow with the GW_HWNDNEXT definition as the 2nd parameter. Like this:
| Code: | auto hWnd = ::FindWindow(nullptr, "Minesweeper");
while (hWnd != 0)
{
hWnd = ::GetWindow(hWnd, GW_HWNDNEXT);
} |
