c++ need help about read/write process memory

hey guys!

firstly i am not american or something so my English isn't good.sorry about it.I want to make bots,hacks for games.I met with c++,read/write process memory.I tried first money,hp,mana shower.but as you guess i couldn't.so i want to help from you.actually i made a video about what i did but video was 4gb so i couldn't upload it to youtube.whatever;

i'm opening game,cheat engine and c++ as administrator,i'm searching my money on cheat engine then i found.i found one adress.then i went to game.I spent my money some.I looked at Cheat Engine and value is changed correctly.then i'm going to c++ writing this codes and run;

Code:

#include <windows.h>
#include <iostream>

using namespace std;

int main()
{
	DWORD address = 0x100579C; // This is the address that we want to read from
int value = 0; // This will store our value. In my case, its an integer, which is the timer
DWORD pid; //This will store our Process ID, used to read/write into the memory
HWND hwnd; //Finally a handle to our window
hwnd = FindWindow(NULL,"EpicDuel - PvP MMORPG Play Now - Opera"); //Finds the Window
	if(!hwnd) //If none, display an error
	{
	cout <<"Window not found!\n";
	cin.get();
	}
	GetWindowThreadProcessId(hwnd,&pid); //Get the process id and place it in pid
	HANDLE phandle = OpenProcess(PROCESS_VM_READ,0,pid); //Get permission to read
if(!phandle) //Once again, if it fails, tell us
		{
		cout <<"Could not get handle!\n";
		cin.get();
		}
		while(1)  //Forever, or until you force close the program
		{
		ReadProcessMemory(phandle,(void*)0x068474A8,&value,sizeof(value),0); //i changed adress with what i found on cheat engine.
		cout << value << "\n"; //Display it
		Sleep(1000); //I was reading the timer which increases every second, so I made my program go through that loop every second
	}
		return 0;
		}

and my c++ program is showing value 0 or 503150133 something like this.cheat engine is working finely.but c++ is not.help me please.

i cant write code for you, but if the Pointer in CE is "green" (static) you need the Process Entry Point of the Memory too.
In CE it Looks like:

Code:

Process.exe + 2B11810

In Pascal it looks like this:

Code:

uses Classes, SysUtils, StdCtrls, Windows, JwaTlHelp32; 
...
function GetBasePointerOfModule(ProcessId: DWORD; Modulename: string): Int64;
var
  FSnapshotHandle: THandle;
  FModulEntry32: MODULEENTRY32;
begin
  Result := 0;
  FSnapshotHandle := CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, ProcessId);
  try
    if FSnapshotHandle <> INVALID_HANDLE_VALUE then
    begin
      FModulEntry32.dwSize := SizeOf(FModulEntry32);
      if Module32First(FSnapshotHandle, FModulEntry32) then
      repeat
        if FModulEntry32.szModule = Modulename then
        begin
          Result := Int64(FModulEntry32.modBaseAddr);
          break;
        end;
      until (not Module32Next(FSnapshotHandle, FModulEntry32));
    end;
  finally
    closeHandle(FSnapshotHandle);
  end;
end;

On 32 Bit Processes you need integer instead of int64

thank you.that adress wasn't static.All i want to do making bots.bot firstable i want to make showers.like mp,hp,money and something like these.For this i'm trying to learn read process memory.After i make showers i will make bots.

I want to understand what's probblem of my program.

Taking a quick look I think u used the dynamic address read the address from. Basically everytime you start up the program that address will be a different one.

So you will have to find a (multilevel)pointer to health to have a consequent reading on it.

i actually knew that.but i don't know how to code with pointers.i know just with dynamic addresses.could you help me? if i start searching i will confuse.i read sometopics from here.people of here are knowledge i think.

I'm not simular with C++ but i just tried your Code example in VS 2015 with another Game, which is 64 Bit and with a Float Value of 20.59332275 on Address 0x162D9A53C
There was a problem with the constant String Title, i have fixed with google.

Code:

#include "stdafx.h"
#include <windows.h>
#include <iostream>

using namespace std;
wchar_t *convertCharArrayToLPCWSTR(const char* charArray)
{
	wchar_t* wString = new wchar_t[4096];
	MultiByteToWideChar(CP_ACP, 0, charArray, -1, wString, 4096);
	return wString;
}
int main()
{
	DWORD address = 0x100579C; // This is the address that we want to read from
	float value = 0; // This will store our value. In my case, its an integer, which is the timer
	DWORD pid; //This will store our Process ID, used to read/write into the memory
	HWND hwnd; //Finally a handle to our window#
	char* WindowName = "Batman™: Arkham Knight";


	hwnd = FindWindow(NULL, convertCharArrayToLPCWSTR(WindowName)); //Finds the Window
	if (!hwnd) //If none, display an error
	{
		cout << "Window not found!\n";
		cin.get();
	}
	GetWindowThreadProcessId(hwnd, &pid); //Get the process id and place it in pid
	HANDLE phandle = OpenProcess(PROCESS_ALL_ACCESS, 0, pid); //Get permission to read
	if (!phandle) //Once again, if it fails, tell us
	{
		cout << "Could not get handle!\n";
		cin.get();
	}
	while (1)  //Forever, or until you force close the program
	{
		ReadProcessMemory(phandle, (void*)0x162D9A53C, &value, sizeof(value), 0); //i changed adress with what i found on cheat engine.
		cout << value << "\n"; //Display it
		Sleep(1000); //I was reading the timer which increases every second, so I made my program go through that loop every second
	}
	return 0;
}

This was the output of the Process:

Code:

I think your Code works

Easiest way would be

Code:

ReadProcessMemory(phandle,(void*)(((clienbase + value) + offset1) + offset2), &value, sizeof (value), 0)

Change this:

Code:

char* WindowName = "Batman™: Arkham Knight";

To:

Code:

w_char* WindowName = L"Batman™: Arkham Knight";

And there is no need to convert

how should i change the codes? for example my pointer is 24124125 and offset is 14 how should put these to code?

thank you again

Something like this?

Code:

ReadProcessMemory(phandle,(void*)(( 0x24124125 ) + 0x14), &value, sizeof (value), 0)

Code:

int value = 0;
int pAddress = 0;
ReadProcessMemory(phandle, (void*)24124125, &pAddress, sizeof(pAddress), 0); // If 24124125 is Hex Value, you need to modify
printf("0x%X Points to -> 0x%X\n", 24124125, pAddress);
ReadProcessMemory(phandle, (void*)(pAddress + 0x14), &value , sizeof(value), 0);

My fail, thx, but i will anyway prefer Pascal ^^

thank you very very much both of you.i want to last thing from you.i'm having problem with founding pointers.most of time i can't find even adress.i'm writing value but Cheat Engine doesn't show me.I have ollydbg too but i don't know how to use this.

guys i can't find pointer .s i hacked paint but samething happened.

when i started program with just adress.its okay.but i can't with pointer.and i guess i don't know how to find pointer.i looked at google i'm doing samething i guess but there is a problem.if you tell me once more maybe i can.please guys.

bytheway if you are know too i want to learn ollydbg.but cheat engine is okay too.

Just do Cheat Engine Tutorial

Youtube for stephen chapman cheat engine tutorial. They are great.

guys for example i just tried find pointer of login's id place.i couldn't again.i found adress this time with string search.then i clicked "find who writes to this adress" then i wrote something to login place.then things came.i clicked them they said your pointer is probably ...... i searched at 2 byte hex that pointer.and there was so many results.i will look at your channel now bytheway.

and once i did cheat engine tutorial.but i still can't.

i guess i am not smart.

man i wasn't know that unknown thing.thanks really. i will watch all of them.tomorrow i will wrtie results here both of you thanks so much.i loved this forum.
