求教一下程序段的讲解

DWORD WINAPI CChatDlg::ListenThread(LPVOID p)
{
	CChatDlg* pDlg = (CChatDlg*)p;
	CSocket ListenSocket, AcceptSocket;
	if (ListenSocket.Create(pDlg->m_ListenPort) == FALSE)
	{
		ListenSocket.Close();
		::PostMessage(pDlg->m_hWnd, WM_ERROR, 1, 1);
		return 0;
	}
	if (ListenSocket.Listen() == FALSE)
	{
		ListenSocket.Close();
		::PostMessage(pDlg->m_hWnd, WM_ERROR, 1, 2);
		return 0;
	}
	CString ip;
	ListenSocket.GetSockName(ip, pDlg->m_ListenPort);
	pDlg->m_ServerOnline = TRUE;
	::PostMessage(pDlg->m_hWnd, WM_SERVER_CREATED, 0, 0);
	while (pDlg->m_ServerOnline)
	{
		if (ListenSocket.Accept(AcceptSocket, NULL, NULL) == FALSE)
		{
			pDlg->m_ServerOnline = FALSE;
			::PostMessage(pDlg->m_hWnd, WM_ERROR, 1, 3);
		}
		if (pDlg->m_ServerOnline == FALSE)
		{
			break;
		}
		CString strIP;
		UINT nPort;
		AcceptSocket.GetSockName(strIP, nPort);
		::PostMessage(pDlg->m_hWnd, WM_CONNECT, (WPARAM)AcceptSocket.Detach(), 0);
		AcceptSocket.Close();
	}
	ListenSocket.Close();
	::PostMessage(pDlg->m_hWnd, WM_SERVER_CLOSED, 0, 0);
	return 0;
}

void CChatDlg::OnClientConnect(SOCKET AcceptSocket, LPARAM lParam)//这一段两句代码不懂什么意思，以及什么情况下会执行这段语句，和上面的::PostMessage(pDlg->m_hWnd, WM_CONNECT, (WPARAM)AcceptSocket.Detach(), 0);有什么关系吗
{ 
	m_ServerSocket.push_back(new CServerSocket(this));
	m_ServerSocket.back()->Attach(AcceptSocket);
}

    m_ServerSocket.push_back(new CServerSocket(this));
    m_ServerSocket.back()->Attach(AcceptSocket);

这两句代码是什么意思

ListenThread监听线程，处理客户端的连接。 放入服务器容器连接列表中，由于MFC CSocket在多线程中使用的问题，需要先Detach(),再Attach() ,处理最新的客户端连接
