how to using CriticalSection

struct CParam
{
    BOOL bActive;
    int nCount;
    CCriticalSection CriticalSection;

    CParam();
};

CParam::CParam()
:bActive(TRUE)
,nCount(0)
{

}

DWORD WINAPI MyThread(LPVOID lpParameter)
{
    CParam *pParam;
    pParam = (CParam*)lpParameter;
    pParam->bActive = TRUE;

    while(1)
    {
        pParam->CriticalSection.Enter();
        ++pParam->nCount;
        pParam->CriticalSection.Leave();
        Sleep(1);
    }

    pParam->bActive = FALSE;

    ExitThread(0);
}



void InitThread()
{
    HANDLE hThread;
    DWORD ThreadId;

    CParam param;
    hThread = CreateThread(NULL, 0, 
        (LPTHREAD_START_ROUTINE)MyThread, (void*)¶m, 0, &ThreadId);

    while(param.bActive == TRUE)
    {
        param.CriticalSection.Enter();
        Sleep(100);
        cout << param.nCount << "\n";
        param.CriticalSection.Leave();
        
    }

    CloseHandle(hThread);
}


int _tmain(int argc, _TCHAR* argv[])
