Hello, I would like to know how we can recover a pointer address in C ++ (64 bits)?
In order to change a value with WriteProcessMemory.

example my baseadress = base;

WriteProcessMemory (hProc, (LPVOID) (((uint8_t *) base) + ?????, & array, number_BYTE, NULL);

If what you mean is how to get the offset, then subtract the module base from your address. 14257890-14000000 (base). Else I don't know what you mean.
