RE: Missing error in WSAAsyncSelect event completion in x64 enviro

Hi Timothy,
I am not sure if I totally understand your scenario. To let me better
understand your issue, could you please describe your issue more detailed
or send me (changliw_at_microsoft_dot_com) your test project for further
research?

My server side code snippets are as follows and it worked fine with
listenning set up:
---------------------------------------------------------------------------
int APIENTRY _tWinMain(...)
{...
WSADATA wsd;
SOCKET Listen;
SOCKADDR_IN InternetAddr;

WSAStartup(MAKEWORD(2,2), &wsd);
Listen = socket (AF_INET, SOCK_STREAM, IPPROTO_TCP);

WSAAsyncSelect(Listen,hWnd, WM_SOCKET, FD_ACCEPT|FD_WRITE|FD_READ);

InternetAddr.sin_family = AF_INET;
InternetAddr.sin_addr.s_addr = htonl(INADDR_ANY);
InternetAddr.sin_port = htons(5150);

bind(Listen, (PSOCKADDR) &InternetAddr,sizeof(InternetAddr));
listen(Listen, 5);
......
}

LRESULT CALLBACK WndProc(...)
{
......
SOCKET Accept;

switch (message)
{
case WM_SOCKET:
if (WSAGETSELECTERROR(lParam))
{
closesocket( (SOCKET) wParam);
break;
}

switch(WSAGETSELECTEVENT(lParam))
{
case FD_ACCEPT:
// Accept an incoming connection
Accept = accept(wParam, NULL, NULL);

// Prepare accepted socket for read,
// write, and close notification
WSAAsyncSelect(Accept, hWnd,
WM_SOCKET,FD_READ|FD_WRITE|FD_CLOSE);
break;

case FD_READ:
// Receive data from the socket in wParam
break;

case FD_WRITE:
// The socket in wParam is ready for sending
data
break;
case FD_CLOSE:
// The connection is now closed
closesocket( (SOCKET)wParam);
break;
}
break;
......
default:
return DefWindowProc(hWnd, message, wParam, lParam);
}
return 0;
}
----------------------------------------------------------------------------

If you have any other questions or concerns, please feel free to let me
know. It is my pleasure to be of assistance.
