Assertion on CSocketFile construction

Hi,
i have this code:

      CSocket sock;
      sock.Create();
      sock.Connect("localhost",80);
--->      CSocketFile file(&sock);
      CArchive in(&file,CArchive::load);
      CArchive out(&file,CArchive::store);

and i get this debug assertion on the marked line:
SOCKCORE.CPP, line 964:
      ASSERT(m_pSocket->m_hSocket != INVALID_SOCKET);

(m_pSocket is &sock)

and two other ones 4 lines later:
      ASSERT(m_pSocket->GetSockOpt(SO_TYPE,&nType,&nTypeLen));
      ASSERT(nType == SOCK_STREAM);

after that it crashes... of course the http server is running.
any clues?

Did you check the return code from the Connect & create calls?  The assertion you're getting basically states that the socket is not valid, thus the association is failing.  My guess is that the Sock Connect call is failing.  Try using the nErr=sock.GetLastError() and looking up the error code.  This might give us more info.

Hey sneedwt,
yes there is a problem, but with .Create, GetLastError returns 10093 and of course connect fails, too (10022)
I traced it back to this line in CAsyncSocket::Socket():

m_hSocket = socket(nAddressFormat,nSocketType,nProtocolType);

(nAddressFormat=2; nSocketType=1; nProtocolType=0)

This fails (m_hSocket stays INVALID_SOCKET), but i don't know why...

Call the AfxSocketInit function in your CWinApp::InitInstance override to initialize Windows Sockets.

The error code 10093 is WSANOTINITIALISED.
