Changing memory values.

tarafından **EMO** Salı Mayıs 31, 2011 2:53 am

here is the code i found that will achieve this in c++.net

CPP / C++ / C Code:

#include
#include
#include
#include

bool ChangeMemVal(const char * ProcessName, LPVOID MemAddress, int NewVal, int size);

void main()
{
printf("=== Pinball Trainer Example. Made by ===\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;
}

Re: Changing memory values.

Well that's definititly a windows program.
I did get this program to compile on a '98 machine using the regular old mingw gcc compiler.
Had to make a few simple changes but ...no .NET was needed. Want to 'learn' how?
What is your OS , your compiler and what EXACLY are the error messages you get.
How did you get that memory address specified in:

CPP / C++ / C Code:

if(ChangeMemVal("PINBALL.EXE", (void*) 0xA90C62, 100000000, 4))
printf("The score has been edited successfully.n");

??? , the 0xA90C62...
hmm, I see the virtual address within the programs' allocation...
btw, cheaters never win
