Re: Using CAsyncSocket as a server.

Just to add to Scott's comment's (since I am bored)

Here is what my listen socket looks like:

CListenSocket::CListenSocket()
{
}

CListenSocket::~CListenSocket()
{
}


// CListenSocket member functions

//LSMsgReceiver is an abstract class that
//has methods I need to call as a result
//of some socket operations like OnAccept, OnReceive....
BOOL CListenSocket::Listen(UINT Port, LSMsgReceiver *Parent,DWORD &Error)
{
m_Parent = Parent;
m_Port = Port;
if (CSocket::Create(Port))
{
if (CSocket::Listen())
{
return TRUE;
}
}

Error = MAKELONG(1,GetLastError());
return FALSE;
}

void CListenSocket::OnAccept(int nErrorCode)
{
if (m_Parent)
{
CSocket Socket;
if (Accept(Socket))
{
//Note that in my OnAccept I detach the socket handle before sending
it to the NewUser method.
//that's because I don't know which CSocket Derived class NewUser
want's to create. I let him
//create it.
SOCKET hSocket = Socket.Detach();
m_Parent->NewUser(m_Port,hSocket);
}
}

CSocket::OnAccept(nErrorCode);
}

AliR.
