I finally got around to doing a little Windows Sockets programming in VC++ 
4.0 today and was quickly greeted with an ugly problem--I can't get it to 
create a socket.

The CSocket::Create() function consistently failed, and 
CSocket::GetLastError() returned WSAEPROTOTYPE. I tried running the CHATTER 
sample program, and its socket creation failed with the same error.

Then I tried tried straight socket API calls (as opposed to using the CSocket 
or CAsyncSocket classes). The "socket" function also failed with the 
WSAEPROTOTYPE error.

Finally, I tried some simple sockets code in VC++ 1.52c and VC++ 2.2. The 
code *worked* in both cases. The *exact same code* works fine when compiled 
with 2.2 but fails when compiled with 4.0.

Here's a sample of my test code:

  WSADATA wsadata;
  WSAStartup( 0x0101, &wsadata );

  SOCKET sock;
  if( INVALID_SOCKET == (sock = socket( PF_INET, SOCK_STREAM, 0 )) )
	{
	int i = WSAGetLastError();
	}

  WSACleanup();

Two other tidbits:  I'm running NT 3.51, and Microsoft's knowledge base 
contained nothing about this problem.

Has anyone else out there encountered this problem?  Is anyone using sockets 
successfully with VC++ 4.0?
