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;
HostEnt = 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;j< m_data[count-1].GetLength();j++)
sizeTotal.cx+=15;
OnInitialUpdate();
flag=FALSE;
}
CServerDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
int y=10;
for(int i=0;i< count;i++)
{ pDC- ＞TextOut(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.
现在介绍客户机程序:
1.创建一个名为"client"的项目,单文档界面.
2.在clientview.h中加入代码：
添加变量:
CString m_data[1000];
HANDLE m_hListenThread;
SOCKET m_sock;
SOCKADDR_IN m_saSrvr;
BOOL Isconnect;
int count;
CSize sizeTotal;
BOOL flag; |
3.在构造函数中初始化变量:
CClientView::CClientView()
{ // TODO: add construction code here
Isconnect=FALSE;
sizeTotal.cy=350;
sizeTotal.cx=300;
flag=FALSE;
} |
4.在析构函数中完成清除操作，代码如上:
5.在菜单中添加"拨号"项:
void CClientView::OnDial()
{// TODO: Add your command handler code here
count=5;
if(m_bInitialized)
{ AfxMessageBox("Already dialing");
return;
}
Cdial dial;
if(dial.DoModal()==IDOK&&!dial.
m_HostAddress.IsEmpty())
{m_saSrvr.sin_family=AF_INET;
m_saSrvr.sin_addr.S_un.S_addr
=htonl(INADDR_ANY);
m_saSrvr.sin_addr.S_un.S_addr
=inet_addr(dial.m_HostAddress);
m_saSrvr.sin_port=htons(5050);
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(0);
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]+="Waiting....";
}
else
m_data[4]+="Failed";
InvalidateRect(NULL);
}
} |
