EVC检测GPRS链接代码(转)

BOOL CRasMonitor::CheckConnectState()
{
    DWORD m_con_cnt = 0;
    RASCONN m_ras_conn;
    m_ras_conn.dwSize = sizeof( RASCONN );
    DWORD dwSize = sizeof( RASCONN );
    DWORD m_ret = RasEnumConnections( &m_ras_conn, &dwSize, &m_con_cnt );
    if ( (0 != m_ret) || (m_con_cnt <= 0) )
        return FALSE;

    RASCONNSTATUS m_ras_state;
    memset( &m_ras_state, 0, sizeof( RASCONNSTATUS ) );
    m_ras_state.dwSize = sizeof( RASCONNSTATUS );
    if ( 0 != RasGetConnectStatus( m_ras_conn.hrasconn, &m_ras_state ) )
        return FALSE;

    return ( m_ras_state.rasconnstate == RASCS_Connected );
}

 

在WM5上工作很好很正常，在WM6上RasEnumConnections返回的值都是0

RasGetConnectStatus()是用来监测RAS拨号后的状态，要查GPRS连接的状态还是用connmgr.h里面提供的API好一些
