{//×Ô¶¨Òå½ÓÊÕ¿Í»§»úÇëÇóµÄÏûÏ¢ ON_MESSAGE(WM_CLIENT_ACCEPT,OnAccept)
if (WSAGETSELECTERROR(lParam))

}
WSAAsyncSelect(Client,m_hWnd,WM_CLIENT_READCLOSE,FD_READ|FD_CLOSE);

}
list.InsertString(0,"连接");
return 0L;
}
1。WPARAM wParam,LPARAM lParam这两个参数什么意思？
2。这个函数在#define WM_CLIENT_ACCEPT WM_USER+101发生时会调用，他是怎么发生这个事件的。是SOCKET对象产生的么？
3。WSAAsyncSelect(Client,m_hWnd,WM_CLIENT_READCLOSE,FD_READ|FD_CLOSE);这句会把FD_READ和FD_CLOSE转化成WM_CLIENT_READCLOSE事件么？怎么转化的？
