clq	2008-10-4 17:48:30 发表编辑一般来说是要在一个线程中不停地检查连接是否是连上的，断开了的话要再连接，所以要有检查函数 BOOL CConnectManager::WaitForConnected ( int nTimeoutSec, DWORD pdwStatus/=NULL/ ) { DWORD dwStartTime = GetTickCount (); BOOL bRet = FALSE; while ( GetTickCount ()-dwStartTime < (DWORD)nTimeoutSec 1000 ) { if ( m_hConnection ) { DWORD dwStatus = 0; HRESULT hr = ConnMgrConnectionStatus ( m_hConnection, &dwStatus ); if ( pdwStatus ) *pdwStatus = dwStatus; if ( SUCCEEDED(hr) ) { if ( dwStatus == CONNMGR_STATUS_CONNECTED ) { bRet = TRUE; break; } } } Sleep ( 100 ); } return bRet; } 最后要记得释放连接 void CConnectManager::ReleaseConnection () { if ( m_hConnection ) { ConnMgrReleaseConnection(m_hConnection, FALSE); m_hConnection = NULL; } } 参见: [url] http://www.cnblogs.com/jsjkandy/archive/2008/08/06/1262445.html
