课程设计报告 课程名称：面向对象程序设计C+ 设计题目： 简易聊天程序设计 专 业：计算机科学与技术 姓 名：金文 学 号： 指导教师：李 晓 虹2015 年 1 月 10 日（一） 系统需求分析用户角度考察系统应具有哪些功能及非功能性需求。能实现用户注册、用户的登录、各客户端能连接起来，服务器能与客户端相连实现用户之间信息的发送与共享。（二）总体设计1、初始化socket，创建服务器端2、维护一个链表，保存所有用户的IP地址、端口信息3、接受用户传送来的聊天信息，然后向链表中的所用用户转发4、接受用户传送来的连接判断命令，并向用户发出相应命令根据连接启动的方式以及本地套接字要连接的目标，套接字之间的连接过程可以分为三个步骤：服务器监听，客户端请求，连接确认。聊天系统客户端服务器用户登录用户注册建立连接监听客户用户数据操作聊天交互（三） 详细设计ChatClient:运行界面：连接服务器：类名变量名函数操作CLoginm_strImagem_strNamem_strSeverIPCLogin(CWnd* pParent /*=NULL*/)DoDataExchange(CDataExchange* pDX)IDD_SENDDLG：对话框名类名变量名相关函数IDD_SENDDLGCChatClientViewcfmAssertValid() constCChatClientView()CChatClientView()Dump(CDumpContext&dc) constGetDocument()OnColor()OnConnect()OnCreate(LPCREATESTRUCT lpCreateStruct)OnDestroy()OnDisconnect()OnFilter()OnInitialUpdate()OnPreparePrinting(CPrintInfo* pInfo)OnSend()PreCreateWindow(CREATESTRUCT& cs)TextOut(LPCTSTR lpszMessage, COLORREF clr)对话框名类名变量名相关函数IDD_ABOUTBOXCOlineListm_imgListAddItem(short i, char* name, char* text)COnlineList()COnlineList()OnCreate(LPCREATESTRUCT lpCreateStruct)OnDblclk(NMHDR* pNMHDR, LRESULT* pResult)Remove(char *name)类名变量名相关函数COlineBarm_ListCtrlAddExStyle(DWORD dwNewStyle)COnlineBar()COnlineBar()OnCreate(LPCREATESTRUCT lpCreateStruct)类名变量名相关函数CMainFramem_wndOnlinem_wndSendm_wndSatusBarm_wndToolBarAssertValid() constCMainFrame()CMainFrame()CMainFrame:Dump(CDumpContext& dc) constOnAddMember(WPARAM wParam, LPARAM lParam)OnCreate(LPCREATESTRUCT lpCreateStruct)OnDblClickItem(WPARAM wParam, LPARAM lParam)OnRemoveMember(WPARAM wParam, LPARAM lParam)OnShowWindow(BOOL bShow, UINT nStatus)PreCreateWindow(CREATESTRUCT& cs)类名变量名相关函数CChatSocketm_pDocCChatSocket(CChatClientDoc* pDoc)CChatSocket()CChatSocket()OnReceive(int nErrorCode)类名变量名相关函数CChatClientViewm_bConnectedm_bFilterm_pArchivelnm_pArchiveOutm_pFilem_pSocketm_strHandlemsgAssertValid() constCChatClientDoc()CChatClientDoc()ConnectSocket(LPCTSTR lpszHandle, LPCTSTR lpszAddress, LPCTSTR m_strImage, UINT nPort)CreateClientItem(REOBJECT* preo) constDisconnect()DisplayMsg(LPCTSTR lpszText)DisplayRecMsg(int type, CString from, CString to,BOOL sec, CString str, COLORREF clr)Dump(CDumpContext& dc) constOnNewDocument()ProcessPendingRead()ReceiveMsg()SendMsg()Serialize(CArchive& ar)talk(int type, CString form, CString to, CString str, COLORREF clr)类名变量名相关函数CChatClientCntrItemAssertValid() constCChatClientCntrItem(REOBJECT* preo, CChatClientDoc* pContainer)CChatClientCntrItem()Dump(CDumpContext& dc) constCChatClientView* GetActiveView()CChatClientDoc* GetDocument()类名变量名相关函数CChatClientAppCChatClientApp()Initlnstance()OnAppAbout()重要代码：void CChatClientDoc:talk(int type, CString form, CString to, CString str, COLORREF clr)CChatClientView* pView = (CChatClientView*)GetView();if(form != m_strHandle & to != m_strHandle & m_bFilter)return;CString temp,to2,first,second;if(type 32 | type TextOut(LPCTSTR)form, RGB(0,0,255);pView-TextOut(LPCTSTR)first, RGB(0,0,0);pView-TextOut(LPCTSTR)to, RGB(0,0,255);pView-TextOut(LPCTSTR)second, RGB(0,0,0);pView-TextOut(LPCTSTR)str,clr);pView-TextOut(LPCTSTR)rn,clr);elsefirst=temp;second=： ;pView-TextOut(form,RGB(0,0,255);pView-TextOut(first,RGB(0,0,0);pView-TextOut(second,RGB(0,0,0);pView-TextOut(str,clr);pView-TextOut(rn,clr);void CChatClientDoc:Disconnect()msg.type = -2;msg.m_bClose = TRUE;msg.from = m_strHandle;msg.to = 所有人;msg.secret = FALSE;msg.m_strText =Hello;msg.color = RGB(0,136,255);
