Greetings mortals.
what i am about to ask might sound a Like its been asked before, but its not...
i need to change the value of a memory address.
say the process name is: "bobdole.exe" (not the same process as the application it self)
memory address: "04A96990"
memory type: "float"
i already know how to do this:
i found this code on a tutorial on this site, and managed to fixe it with some help.
CODE
#include <windows.h>
#include <tlhelp32.h>
#include <conio.h>
#include <stdlib.h>
#include <stdio.h>
bool ChangeMemVal(const char * ProcessName, LPVOID MemAddress, int NewVal, int size);
int main()
{
printf("=== Pinball Trainer Example. Made by <your name here> ===\n\n");
if(ChangeMemVal("PINBALL.EXE", (void*) 0xA90C62, 100000000, 4))
printf("The score has been edited successfully.\n");
else
printf("An error occured while attempting edit the score.\n");
system("PAUSE");
return 0;
}
/* This function modifys a memory address according to its arguments.
Arguments :
ProcessName - the process we want to modify
MemAddress - the memory address we want to modify
NewVal - the value we want to change the memory address to
size - the size of the memory address
Returns :
the success of the edit.
*/
bool ChangeMemVal(const char * ProcessName, LPVOID MemAddress, int NewVal, int size)
{
HANDLE hProcessSnap;
HANDLE hProcess = NULL;
PROCESSENTRY32 pe32;
hProcessSnap = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS, 0 );
pe32.dwSize = sizeof( PROCESSENTRY32 );
Process32First(hProcessSnap, &pe32);
do
{
if(!strcmp(pe32.szExeFile, ProcessName))
{
hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pe32.th32ProcessID);
break;
}
}
while(Process32Next(hProcessSnap, &pe32));
CloseHandle( hProcessSnap );
if(hProcess != NULL)
{
WriteProcessMemory(hProcess, MemAddress, &NewVal, size, NULL); // write the value
CloseHandle(hProcess);
return true;
}
return false;
}
the problem is that the address, sometimes don't stay the same. some addresses change every time the program starts.
i know this requires that we know what writes to that address. lets say we know what writes to that address. how would i go about to change this code and make it follow the thing that writes to this address and figure out the address.
simplified: address a writes to address b we know wat a is. we try to find b by knowing that a writes to it
any help would be greatly appreciated.
sob sob sob. cry cry. YELL . cut cut. pass out...
