CAsyncSocket::Connect() keeps returning WSAENOTSOCK The descriptor is not a socket.

Hi there,

I'm trying to build a MFC-based Client app using the CAsyncSocket class and I keep receiving this error when I
try to connect to the specified address and port. A portion of my code is provided below:

if (!AfxSocketInit())
//Display error
else
{
CClientSocket* pSock = new CClientSocket;
if (!pSock->Create())
{
//Display error
delete pSock;
}
//Else created socket
}

...
int nError;
const char *addr = "xxx.xxx.xxx.xxx";
if (!CAsyncSocket::Connect(addr, 3490))
{
nError = CAsyncSocket::GetLastError();
if (nError == WSAEWOULDBLOCK)
//Asynchronous Attempt started
else
//Display error -THIS IS WHERE I GET TO!
}

This is where I keep receiving the (WSAENOTSOCK The descriptor is not a socket. - 10038) error. I have debugged it all the way to the point where ConnectHelper() is called and the returned m_hSocket handle is invalid. The SockAddr structures are getting filled correctly too. I really don't understand what I'm doing wrong. The included header file is <afxsock.h>. I know that the server is working because I have another test program (client) that uses the <winsock2.h> file, the server can communicate with the client. I really need some help. Thanks in advance.

try to bind the socket before the Connect(). Maybe that helps.

Please post code that would compile. Yours obviously would not. For example, CAsyncSocket::Connect is a member function, not a static function, so this line of code makes no sense at all, and could notpossibly compile

Code:

---

if (!CAsyncSocket::Connect(addr, 3490))

---

Please also use [ code ][ /code ] tags to format you code neatly.

PS: for a client, there is no need to call bind() explicitly. The call to connect() implicitly binds the socket.
