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
int count;//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
WSADATA WSAData;
BOOL flag;
SOCKADDR_IN saClnt;
int saClntLen;
BOOL Isconnect;//是否连接论文网http://www.751com.cn/
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);2358
