特别活动通过联系点处理。 你们需要写你们自己的目录,以落实你们感兴趣的任何活动。 然后,你需要将其与引起事件的COM物体连接起来。 首先,ConctionPointContainer在座标,然后找到古董会相应链接点。 你称其咨询方法将其与你的活动汇合。

class CSrvrSessionEvents: public _ISrvrSessionEvents
{
public:
    HRESULT OnLogin(long LoginResult)
    {
        // do something
        return S_OK;
    }
    // implement rest of _ISrvrSessionEvents
};

ISrvrSession* pSrvrSession = ...; // get ISrvrSession from somewhere
_ISrvrSessionEvents* pSrvrSessionEvents = new CSrvrSessionEvents();
IConnectionPointContainer* pCPC = NULL;
pSrvrSession->QueryInterface(IID_IConnectionPointContainer, &pCPC);
IConnectionPoint* pCP = NULL;
pCPC->FindConnectionPoint(__uuidof(_ISrvrSessionEvents), &pCP);
DWORD dwCookie = 0;
pCP->Advise(pSrvrSessionEvents, &dwCookie);
pSrvrSession->Connect(); // I assume this fires some events
pCP->Unadvise(dwCookie);
