前一阵子，产测上需要这么一种功能------检测电脑是否睡眠过，现在记录一下主要的实现代码。

// TODO: 在此添加额外的初始化代码
    	CString strCommandLine = GetCommandLine();
    	strCommandLine.TrimLeft().TrimRight();
    	CString strTimeout;
    	int idx = strCommandLine.Find(_T(" "));
    	if (idx != -1)
    	{
    		strTimeout = strCommandLine.Mid(idx+1);
    		strTimeout.TrimLeft().TrimRight();
    				
    		//m_nTimeout = _ttoi(strTimeout);
    		//======================================================//
    		m_nTimeout = 50;
    	}
    	
    	TRACE(_T("m_nTimeout = %d\r\n"),m_nTimeout);
    
    	SetTimer(TIMER1,TIMER1_INTERVAL,NULL);

LRESULT CPowerMonitorDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
    {
    	// TODO: 在此添加专用代码和/或调用基类
    	//TRACE(_T("%04x\r\n"),message);
    	switch (message)
    	{
    		
    
    	case WM_POWERBROADCAST:
    		{
    			TRACE(_T("%04x\r\n"),wParam);
    			//系统睡眠了
    			if(wParam == PBT_APMSUSPEND)
    			{
    				m_bAPMSUSPEND = TRUE;
    			}
    			//系统唤醒了
    			else if (wParam == PBT_APMRESUMESUSPEND)
    			{
    				m_bAPMRESUMESUSPEND = TRUE;
    			}
    		}
    		break;
    	default:
    		break;
    	}
    	return CDialogEx::WindowProc(message, wParam, lParam);
    }
