memset(m_pDeviceStatus, 0, 128);
        //cout << "m_pDeviceStatus: " << (int)m_pDeviceStatus[0] << endl;
        WORD state=dsoHTGetState(m_nDeviceIndex, m_pDeviceStatus);
        //cout << "m_pDeviceStatus: " << (int)m_pDeviceStatus[0] << endl;
        //cout << "dsoHTGetState: " << state << endl;

        if (!(m_pDeviceStatus[0] & 2))
        //if (!(state & 2))
        {        cout << "数据不可读取" << endl;
                return false;}

打印了一下m_pDeviceStatus[0]=56，这是什么意思，用的VCdemo里的代码
