Good evening, I would like to modify in c ++ the values of addresses of 64 bit games. The following code is 32-bit. What should I change ?

#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
#ifdef __MINGW32__
#include <windows.h>
#endif

using namespace std;
int main(){




DWORD Target = 0x22ACBA164D0;
SIZE_T bytes = 0;
BYTE exampleBytes[5] = { 0x8B,0xFF,0x55,0x8B,0xEC };

HWND hWnd;
while( !( hWnd = FindWindow( NULL, "Calculatrice" ) ) )
Sleep( 100 );

DWORD PID;
while( !( GetWindowThreadProcessId( hWnd, &PID ) ) )
Sleep( 100 );

// as learn_more said, you need process handle.
HANDLE hProcess;
while( !( hProcess = OpenProcess( PROCESS_VM_OPERATION | PROCESS_VM_READ | PROCESS_VM_WRITE, 0, PID ) ) )
Sleep( 100 );

WriteProcessMemory( hProcess, (PVOID)Target, exampleBytes, 5, &bytes );
system("pause");
return 0;
}

I would try replacing DWORD with int where applicable.
A 64bit compiler will make them 64bit ints.
You might want to read up on the compiler's help and the docs of the API you are trying to use.

DWORD can be replaced with DWORD_PTR for 64bit compatibility. However, it is recommended to avoid Microsofts Windows-implemented typedefs like these and use the newer standard types.

ie. in this case, you'd want to use intptr_t / uintptr_t.
