网络编程已经成为一种时髦，以TCP/IP协议的网络更为流行.自己编一个服务器与客户机互相传送消息的程序,以便增加自己网络编程的经验。下面我就介绍一下我编的程序。 首先介绍服务器程序： 1.创建一个名为"server"的项目,单文档界面. 2.在serverview.h中加入代码：
#include "winsock.h" 添加变量：
CSize sizeTotal;//控制滚动条intcount;//信息条数CString m_data[1000];//信息存放char Hostname[260];char Hostaddress[20];//主机IP地址SOCKET m_sock;HANDLE m_hListenThread;//线程BOOL m_bInitialized;//是否初始化WSADATAWSAData;BOOL flag;SOCKADDR_IN saClnt;int saClntLen;BOOL Isconnect;//是否连接 3.在serverview.cpp中重载CServerView()构造器,创建并绑定嵌套字：
CServerView::CServerView(){ // TODO: add construction code here Isconnect=FALSE; flag=FALSE; sizeTotal.cy=350; sizeTotal.cx=300; m_hListenThread; count=5; int status; WSADATA wsaData; m_data[0]="initializing Windows Sockets DLL...."; if((status=WSAStartup(0x0101,&wsaData))==0) { m_data[0] ="Succeeded"; m_bInitialized=TRUE; } else { m_bInitialized=FALSE; } m_sock=socket(AF_INET,SOCK_DGRAM,0); m_data[1]="Creating socket...."; if(m_sock==INVALID_SOCKET) { m_data[1] ="Failed"; } m_data[1] ="Succeeded"; m_data[2]="Binding socket...."; sockaddr_in sa; sa.sin_family=AF_INET; sa.sin_addr.S_un.S_addr=htonl(INADDR_ANY); sa.sin_port=htons(5050); if(bind(m_sock,(PSOCKADDR)&sa,sizeof(sa))==SOCKET_ERROR) { m_data[2] ="Failed"; closesocket(m_sock); } m_data[2] ="Succeeded"; m_data[3]="Creating listener thread...."; unsigned long idThread; m_hListenThread=CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)Listen,(void *)this,0,&idThread); if(m_hListenThread) { m_data[3] ="Succeeded"; m_data[4] ="Listening...."; } else m_data[4] ="Failed";} 4.在析构函数中完成必需的清除操作:
CServerView::~CServerView(){ if(m_bInitialized) WSACleanup(); closesocket(m_sock); if(m_hListenThread) ::TerminateThread(m_hListenThread,0);} 5.定义接收和处理消息的线程:
long WINAPI Listen(CServerView *pView){ char msg[2000]=""; intnchar; SOCKADDR_IN saClnt; int saClntLen; while(1) { saClntLen=sizeof(saClnt); nchar=recvfrom(pView->m_sock,msg,1024,0,(PSOCKADDR)&saClnt,&saClntLen); if(nchar<0) { pView->m_data[pView->count ] ="Error in recvfrom\n"; pView->InvalidateRect(NULL); } else { switch(msg[0]) { case'A': wsprintf(msg,"A: Client from %s attached\n",inet_ntoa(saClnt.sin_addr)); pView->m_data[pView->count ]=msg; pView->flag=TRUE; pView->InvalidateRect(NULL); pView->Isconnect=TRUE; pView->saClnt=saClnt; pView->saClntLen=saClntLen; sendto(pView->m_sock,msg,1024,0,(PSOCKADDR)&saClnt,saClntLen); break; case 'D': wsprintf(msg,"D: Client form %s detached\n",inet_ntoa(saClnt.sin_addr)); pView->m_data[pView->count ]=msg; pView->flag=TRUE; pView->InvalidateRect(NULL); pView->Isconnect=FALSE; sendto(pView->m_sock,msg,1024,0,(PSOCKADDR)&saClnt,saClntLen); break; case 'R': saClntLen=sizeof(saClnt); pView->m_data[pView->count ]=msg; pView->flag=TRUE; pView->InvalidateRect(NULL); break; default: break; } } } return(0);} 6.在程序菜单项中添加"本机IP地址":
void CServerView::OnIp() { int WSAReturn; WSAReturn=WSAStartup( 0x0101, &WSAData ); if( WSAReturn == 0 ){ gethostname( Hostname, 260 ); struct hostent *pHostEnt; pHostEnt = gethostbyname( Hostname); if( pHostEnt != NULL ){ wsprintf( Hostaddress, "%d.%d.%d.%d", ( pHostEnt->h_addr_list[0][0] & 0x00ff ), ( pHostEnt->h_addr_list[0][1] & 0x00ff ), ( pHostEnt->h_addr_list[0][2] & 0x00ff ), ( pHostEnt->h_addr_list[0][3] & 0x00ff ) ); CString out; out.Format(Hostaddress); AfxMessageBox(out); } }} 7.在程序菜单中添加"发送消息"：
void CServerView::OnSendmessage() { // TODO: Add your command handler code here char msg[2000]; Csend Sendmessage; if(Sendmessage.DoModal() ==IDOK&&!Sendmessage.m_Message.IsEmpty()) { wsprintf(msg,"R: " Sendmessage.m_Message); sendto(m_sock,msg,1024,0,(PSOCKADDR)&saClnt,saClntLen); m_data[count ]=Sendmessage.m_Message; flag=TRUE; InvalidateRect(NULL); }} 8.为发送消息项添加一个对话框的类,名为send,有一个文本框,用来发送消息.并为文本框添加CString m_Message 变量,并在ServerView.cpp中添加#include "send.h" 9.为发送消息项添加一个判断函数:
void CServerView::OnUpdateSendmessage(CCmdUI* pCmdUI) { // TODO: Add your command update UI handler code here pCmdUI->Enable(FALSE); if(Isconnect) pCmdUI->Enable(TRUE);} 10.再窗口显示消息:
void CServerView::OnDraw(CDC* pDC){ if(flag) { sizeTotal.cy =20; for(int j=65;jTextOut(10,y,m_data[i]); y =20; } // TODO: add draw code for native data here} 11.在Project中点击Settings中选择Link项添加wsock32.lib. 最后编译程序,就可以得到Server.exe程序. 共2页。 1 2 :
