如何用Socket发送两个回车换行符号，udp协议的。

Question

如题：麻烦大家了

Answer 1

char szsend[4];
sprintf(szsend,"\r\n\r\n");
int iSend=m_socket.Send(szSend,4,0);

Answer 2

char szsend[4];
sprintf(szsend,"\r\n\r\n");
UINT iport=80;//设置端口号
int isend=m_udpsock(szsend,4,iport,"127.0.0.1",0);

Answer 3

在vckbase.com里看的：
void CFasonDlg::OnSend() 
{
// TODO: Add your control notification handler code here
UpdateData(TRUE);
CString m_Getstring;

this->m_Cob.GetLBText(m_Cob.GetCurSel(),m_Getstring);
if(m_Getstring==_T("Red"))
yuan1.color=1;
if(m_Getstring==_T("Green"))
yuan1.color=2;
if(m_Getstring==_T("Blue"))
yuan1.color=3;

yuan1.x=m_x;
yuan1.y=m_y;
yuan1.r=m_r; p=&yuan1; CDSocket m_hSocket;
m_hSocket.Create(2330,SOCK_DGRAM);
m_hSocket.SendTo( p,sizeof(yuan1),3550,"127.0.0.1");    m_x=0;
m_y=0;
m_r=0;
m_hSocket.Close();
UpdateData(FALSE);
}
