描述:
哪位知道在VC中如何使用Winsock控件？哪里有关于VC中使用Winsock控件的全面介绍？
在OnConnectionRequest事件中我加入了一个ctrlWinsock.Accept(requestID)接受远程连接（详见下面源代码），但是测试时，发现客户端刚连接上，马上server端就断了，再去连接还会重复这个现象，这是怎么回事？
下面是部分代码：
void CMyTest::OnButtonListen()
{
// TODO: Add your control notification handler code here
VARIANT localport;
VARIANT localip;
CString strport;
CString strip;
VARIANT vtCommand;
CString m_command;
VARIANT vtData;
VARIANT vtType;
localport.vt=VT_BSTR;
localip.vt=VT_BSTR;
strport="1234";
strip="192.168.1.1";
vtCommand.vt=VT_BSTR;
m_command="Server Send";
vtData.vt=VT_BSTR;
vtType.vt=VT_ERROR;
localport.bstrVal=strport.AllocSysString();
localip.bstrVal=strip.AllocSysString();
m_ctrlWinsock.SetProtocol(1);// 选择UDP协议，1=UDP, 0=TCP
m_ctrlWinsock.Bind(localport, localip);
m_ctrlWinsock.Listen();
}
void CMyTest::OnConnectionRequestWinsockServer(long requestID)
{
// TODO: Add your control notification handler code here
m_ctrlWinsock.Accept(requestID);
}
void CMyTest::OnButtonStop()
{
// TODO: Add your control notification handler code here
m_ctrlWinsock.Close();
}
void CMyTest::OnCloseWinsockServer()
{
// TODO: Add your control notification handler code here
m_ctrlWinsock.Close();
m_ctrlWinsock.Listen();
}
