服务程序中的WinSock消息

Question

请教大家在服务程序中(windows服务程序，没有窗口的那种）,能否接收（或是触发）winsock消息，例如：能够触发OnAccept，如果能，应该怎样做。我的程序是这样的，从CAsyncSocket类继承了一个新的类，在该类中处理winsock事件。在对话框测试中，都很正常，包括心跳包等都测试通过，但在服务程序中，只能建立连接，没有触发OnAccep（但是客户端显示连接上了），请教大家，这是为什么？

Answer 1

CAsyncSocket需要创建一个窗口的阿，是系统自己创建的
可以考虑用一个线程，用wsaselect帮定SOCKET的事件，用WSAFORMUTIPLEOBJECT来检视有没有网络时间，用WSAEnumNetworkEvents来确定是哪个网络消息

以下是我在pda上面用倒的，可以参考

DWORD dwRet = WSA_WAIT_EVENT_0;
CString strErr; CTCPClientCE *pSocket; WSANETWORKEVENTS netEvents;
//得到CTCPClientCE实例指针
pSocket = (CTCPClientCE*)lparam;
//定义读事件集合
for(;;)
{
dwRet = WSAWaitForMultipleEvents(2, pSocket->m_hWSAEvent, FALSE, WSA_INFINITE, FALSE); switch(dwRet)
{
