1. Chat Message过程

* 向Server发信息

CChatMainDlg::SendData()

CChatSession::SendData()

CConfSession(ISessionClient)::SendData()

CConference::SenddData()

CConfPort::SendData()                                                            // reliable or assitant connection ? 2011/12/04

CConfConnection::SendData()                                               // package 的优先级处理。2011/12/04

Server

 

* 从Server接收信息

Server

CConfConnection::OnReceiveData()

CConference::OnReceiveData()                                              // Why not CConfPort this time ?

                                                                                                        // 是否因为CConfPort提供了reliable/assistant connection选择，而receive的时候不需要？ 2012/04/06

CConfSession(ISessionClient)::OnReceiveData()

CChatSession::OnReceiveData()

CChatMainDlg::OnReceiveData()

CChatMainDlg::Display Chat Message

 

CConfManage -> CConfSession-> CConference -> XXXConnection -> Server ?

 

2. step-by-step running

 

Loaded 'C:\WINDOWS\system32\wshtcpip.dll', no matching symbolic information found.

A: The IP changed to 172.16.14.3

Q: Why no issue for Controller ?

Q：如何给chat module的DllMain()设置break point？

      A：这是不可能的。只有当dll加载后才能调break point，而如果dll已经被加载，则意味着DllMain()已经执行过了。

3. rtchat.dll加载过程：

注：在SessionCreateRequest的响应中，创建Chat Component，并将Session与其绑定？

4. conference/session/component 创建过程

CMainFrame::OnCreate()->

CConfManage::CreateConference() -> CConfManage::JoinConference()

CConference::HandleJoinConfRspn()-> Enroll Conf Request -> 

CConference::HandleEnrollConfResp() ->

CConfManage::OnConferenceJoinConfirm() -> 

CConfManaage::CreateAllSessions() -> 

CConference::CreateSession() ->

......

CConference::OnReceiveData() -> CConference::HandleSessionCreateIndicate() -> OnSessionCreateConfirm() ->

CConfManage::CreateComponent() -> 

component dll loaded.
