I''m just trying to make a simple program that connects two computers then sends a simple mess from one to the other. Everything works fine until I ask the server to call recv(..). I end up getting the error message WSAENOTCONN (Socket is not connected). Here''s the source:

// included the winsock library


#include <winsock.h>
#include <iostream.h>

#define NETWORK_ERROR -1
#define NETWORK_OK     0

int main()
{
	WORD sockVersion;
	WSADATA wsaData;
	int error = 0;

	char buffer[256];		

	sockVersion = MAKEWORD(2, 0);

	WSAStartup(sockVersion, &wsaData);

	SOCKET listeningSocket;

	listeningSocket = socket (AF_INET, SOCK_STREAM, IPPROTO_TCP);

	if (listeningSocket == INVALID_SOCKET)
	{
		cout << WSAGetLastError() << endl;
		
		WSACleanup();
		return NETWORK_ERROR;
	}

	SOCKADDR_IN serverInfo;

	serverInfo.sin_family = AF_INET;
	serverInfo.sin_addr.s_addr = INADDR_ANY;
	serverInfo.sin_port = htons(8888);

	error = bind(listeningSocket, (LPSOCKADDR)&serverInfo, sizeof(struct sockaddr));

	if (error == SOCKET_ERROR) 
	{
		cout << WSAGetLastError() << endl;
		
		WSACleanup();
		return NETWORK_ERROR;
	}

	error = listen(listeningSocket, 10);

	if (error == SOCKET_ERROR)
	{
		cout << WSAGetLastError() << endl;
		
		WSACleanup();
		return NETWORK_ERROR;
	}
	
	cout << "listening for client" << endl;
	SOCKET theClient;
	theClient = accept(listeningSocket, NULL, NULL);
	if (theClient == INVALID_SOCKET)
	{
		cout << "accept(listeningSocket, NULL, NULL) failed" << endl;
		WSACleanup();
		return NETWORK_ERROR;
	}
	cout << "client connected" << endl;
	
	error = recv(listeningSocket, buffer, 256, 0);

	if (error == SOCKET_ERROR) 
	{
		cout << WSAGetLastError() << endl;
		WSACleanup();
		return NETWORK_ERROR;
	} 
	
	cout << buffer << endl;

	closesocket(theClient);
	closesocket(listeningSocket);


	// Shutdown Winsock

	WSACleanup();
	return NETWORK_OK;
}

Let me know if you need to see the client source (I can''t imagine why you would...but who knows)

I remember looking at that and thinking something was off, but then forgot all about it a minute later.

Thanks for your help...works perfectly now.
