    WriteProcessMemory doesn't work

    Hey guys, Ive got a problem, I want to have noRecoil and noFlash so I opened the process like this
    Code:
    mw2_hwnd = FindWindow(NULL,L"AlterIWNet");
    GetWindowThreadProcessId(mw2_hwnd,&mw2_pid);
    mw2_process_w = OpenProcess(PROCESS_VM_WRITE,false,mw2_pid);
    then wrote the new hexcode like this
    Code:
    #define ADDR_FLASH	0x00457310
    BYTE NoFlash[6] = {0xB8, 0x00, 0x00, 0x00, 0x00, 0xC3};
    WriteProcessMemory(mw2_process_w,(PVOID)(ADDR_FLASH),&NoFlash,6,NULL);
    but in game nothing happens.
    What do I have to do?

    Code:
    mw2_hwnd = FindWindowA(NULL, "alterIWnet");
    If nothing happens then try to call the VirtualProtectEx(), maybe the address is write protected.
