VC(MFC)实现 简单的聊天室程序.doc

网络程序设计课 程 设 计 报 告 书题 目： 简单的聊天室程序 专 业： 网络工程 完成日期： 2012年6月7日 一、 题目:简单的聊天室程序要求:本题是一个简单的聊天室程序，采用客户/服务器模式，分为客户端程序和服务器端程序。由于服务器只能支持一个客户，实际上是一个点对点通信的程序。客户端程序和服务器程序通过网络交换聊天字符串内容，并在窗口的列表框中显示。l 。二、 系统概要设计聊天室是分客户端和服务端两个应用程序的， 两个应用程序要想实现交互必 须编写相应的指令和识别指令的代码，我写的这是个指令依次是 启动 停止 用户退出 的命令，但用户想要进行以上动作中的任何 一个时，在用户按下按键的时候，客户端都是向服务端发送相应的指令，再由服 务端实际的执行。三、系统详细设计对概要设计中提到的功能函数进行详细设计。服务器端：/ ChatRoomServerDlg.cpp : implementation file/#include stdafx.h#include ChatRoomServer.h#include ChatRoomServerDlg.h#include ListenSocket.h#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE = _FILE_;#endif/ CAboutDlg dialog used for App Aboutclass CAboutDlg : public CDialogpublic:CAboutDlg();/ Dialog Data/AFX_DATA(CAboutDlg)enum IDD = IDD_ABOUTBOX ;/AFX_DATA/ ClassWizard generated virtual function overrides/AFX_VIRTUAL(CAboutDlg)protected:virtual void DoDataExchange(CDataExchange* pDX); / DDX/DDV support/AFX_VIRTUAL/ Implementationprotected:/AFX_MSG(CAboutDlg)/AFX_MSGDECLARE_MESSAGE_MAP();CAboutDlg:CAboutDlg() : CDialog(CAboutDlg:IDD)/AFX_DATA_INIT(CAboutDlg)/AFX_DATA_INITvoid CAboutDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CAboutDlg)/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CAboutDlg, CDialog)/AFX_MSG_MAP(CAboutDlg)/ No message handlers/AFX_MSG_MAPEND_MESSAGE_MAP()/ CChatRoomServerDlg dialogCChatRoomServerDlg:CChatRoomServerDlg(CWnd* pParent /*=NULL*/): CDialog(CChatRoomServerDlg:IDD, pParent)/AFX_DATA_INIT(CChatRoomServerDlg)/ NOTE: the ClassWizard will add member initialization here/AFX_DATA_INIT/ Note that LoadIcon does not require a subsequent DestroyIcon in Win32m_hIcon = AfxGetApp()-LoadIcon(IDR_MAINFRAME);void CChatRoomServerDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CChatRoomServerDlg)DDX_Control(pDX, IDC_BUTTON_STOP, m_IDC_BUTTON_STOP);DDX_Control(pDX, IDC_BUTTON_START, m_IDC_BUTTON_START);/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CChatRoomServerDlg, CDialog)/AFX_MSG_MAP(CChatRoomServerDlg)ON_WM_SYSCOMMAND()ON_WM_PAINT()ON_WM_QUERYDRAGICON()ON_BN_CLICKED(IDC_BUTTON_START, OnButtonStart)ON_BN_CLICKED(IDC_BUTTON_STOP, OnButtonStop)/AFX_MSG_MAPEND_MESSAGE_MAP()/ CChatRoomServerDlg message handlersBOOL CChatRoomServerDlg:OnInitDialog()CDialog:OnInitDialog();/ Add About. menu item to system menu./ IDM_ABOUTBOX must be in the system command range.ASSERT(IDM_ABOUTBOX & 0xFFF0) = IDM_ABOUTBOX);ASSERT(IDM_ABOUTBOX AppendMenu(MF_SEPARATOR);pSysMenu-AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);/ Set the icon for this dialog.
