CEvent MFC replication

继续进行一系列MFC类复制（对于知识渊博的），这是Cevent类复制：

class CEvent {
    HANDLE m_hEvent;
public:
    CEvent(
        BOOL bInitialState,
        BOOL bManualReset)
    {
        LPSECURITY_ATTRIBUTES lpEventAttributes = NULL;
        m_hEvent = CreateEvent(lpEventAttributes, 
                                bManualReset,
                                bInitialState,
                                NULL);
    }
    ~CEvent()
    {
        m_hEvent = NULL;
    }
    BOOL SetEvent()
    {
        return ::SetEvent(m_hEvent);
    }
    BOOL ResetEvent()
    {
        return ::ResetEvent(m_hEvent);
    }
    HANDLE GetHandle()
    {
        return m_hEvent;
    }
    operator HANDLE()
    {
        return m_hEvent;
    }
};

该代码已与答案进行了考虑。
