Called by the framework to notify this socket that there is data in the buffer that can be retrieved by calling the Receive member function.
virtual void OnReceive(
int nErrorCode
);
Parameters
nErrorCode
The most recent error on a socket. The following error codes apply to the OnReceive member function:0 The function executed successfully.
WSAENETDOWN The Windows Sockets implementation detected that the network subsystem failed.
Remarks

Example
void CMyAsyncSocket::OnReceive(int nErrorCode) // CMyAsyncSocket is
// derived from CAsyncSocket
{
static int i = 0;
i++;
TCHAR buff[4096];
int nRead;
nRead = Receive(buff, 4096);
switch (nRead)
{
case 0:
Close();
break;
case SOCKET_ERROR:
if (GetLastError() != WSAEWOULDBLOCK)
{
AfxMessageBox (_T("Error occurred"));
Close();
}
break;
default:
buff[nRead] = _T('\0'); //terminate the string
CString szTemp(buff);
m_strRecv += szTemp; // m_strRecv is a CString declared
// in CMyAsyncSocket
if (szTemp.CompareNoCase(_T("bye")) == 0)
{
ShutDown();
s_eventDone.SetEvent();
}
}
CAsyncSocket::OnReceive(nErrorCode);
