well doesn't appear like your pointer has an offset there so it's not necessary. however it is necessary to dereference 'direccion' by giving it a type DWORD* and then dereferencing that. eg.

Code:
DWORD* dynamicAddress = *(DWORD*)0x0x00C1AE9A;

Thanks for reply!

I put:

DWORD* direccion = *(DWORD*)0x00C1AE9A;
const long nuevaPuntuacion=999999;

But:
In function `int WinMain(HINSTANCE__*, HINSTANCE__*, CHAR*, int)':

And

invalid conversion from `long unsigned int' to `DWORD*'

You'll be changing the data in your own process if you do it like that. Unless this is a DLL.

No, look...

Code:
#include<windows.h>
#include<stdio.h>


int WINAPI WinMain (HINSTANCE hThisInstance,
HINSTANCE hPrevInstance,
LPSTR lpszArgument,
int nFunsterStil)

{
DWORD* direccion = *(DWORD*)0x00C1AE9A;
const long nuevaPuntuacion=999999;

long viejaPuntuacion;
char mensaje[256];


HWND hwnd;
DWORD pid;
HANDLE phandle;


hwnd = FindWindow(NULL, "3D Pinball Windows: cadete espacial");
if(!hwnd)
{
MessageBox(NULL, "No se esta ejecutando Pinball", "Error", MB_OK | MB_ICONERROR);
return -1;
}
GetWindowThreadProcessId(hwnd, &pid);
phandle = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);
if(!phandle)
{
MessageBox(NULL, "Error al obtener el handle del proceso", "Error", MB_OK | MB_ICONERROR);
return -2;
}

ReadProcessMemory(phandle,(LPVOID)direccion,(LPVOID)&viejaPuntuacion,sizeof(viejaPuntuacion),0);
WriteProcessMemory(phandle, (LPVOID)direccion, (LPVOID) &nuevaPuntuacion, sizeof(nuevaPuntuacion), 0);

sprintf(mensaje, "Tu puntuacion ha cambiado de %ld a %ld", viejaPuntuacion, nuevaPuntuacion);

MessageBox(NULL, mensaje, "Listo", MB_OK);

return 0;
}


but the error is: invalid conversion from `long unsigned int' to `DWORD*'


Thanks for reply!

is probably going to blow up in your face if it even somehow compiled.
even if you had it correct, you'd just be reading garbage.

delete this.

Read the value in that address with ReadProcessMemory. Add whatever offset you have to that value and then you have the address to use Read/WriteProcessMemory on.

I did!
The error was:
Code:
DWORD* direccion = *(DWORD*)0x00C1AE9A;


And now work:
Code:
DWORD* direccion = (DWORD*)0x00C1AEBA;



Now i have another problem... The dinamic address of a game... Is a IP, this ip connect with the server game. I want edit this ip with writeprocessmemory but i canīt see the pointer becouse the dinamic address (the IP), isenīt change (the value of IP)

Can somebody help me? Thanks!

Sorry for my english i am from argentina.

it could have an offset, it could be hiden.

u could try or the pointer works without an offset by restarting the prgram, if it still has the value u want, its good, otherwise there is an offset which is harder to find,

and u could google for, Readprocessmemory and wirteprocessmemory

There is no offset. You can tell from his cheat table

mov [eax],ecx can be rewritten as
mov [eax+0000000000000000000000000000000000000000],ecx

I'd say the offset is 0000000000000000000000000000000000000000

so, read the 4 byte value at the given address
apply the offset (0000000000000000000000000000000000000000)
read the address this new value represents
and you have the final address

also,because 0x00C1AE9A isn't shown as green, I doubt it's a static address. But with some luck it'll stay the same.( It's low enough to get the same address each time)
