winsock problem

Heres the code, for a basic client/server app which i got from a tutorial as a base.

Code:

#include <iostream.h>
#include <winsock2.h>

const unsigned int maxchars = 200;

void client()
{
    char dest_ip[15];

    cout << "Destination IP Address: ";
    cin >> dest_ip;
    cout << endl;

    SOCKET exp;

    if (exp = socket(AF_INET,SOCK_STREAM,0))
	   cout << "--- Sending socket created successfully." << endl;
    else
    {
	   cout << "Can't create sending socket. Aborting." << endl;
	   WSACleanup();
	   exit(0);
    }

    sockaddr_in target;

    target.sin_family = AF_INET;
    target.sin_port = htons(5656);
    target.sin_addr.s_addr = inet_addr(dest_ip);

    if (connect(exp,(LPSOCKADDR)&target,sizeof(target)) == SOCKET_ERROR)
    {
	   cout << "Can't connect. Aborting." << endl;
	   WSACleanup();
	   exit(0);
    }
    else
    {
	   cout << "--- Connected successfully." << endl;
	   cout << " -| Enter 666 when you want to end the session." << endl;

	   char buff[maxchars];

	   while(buff[0] != '6' || buff[1] != '6' || buff[2] != '6')
	   {
		  cin.getline(buff,maxchars);
		  cout << "Enter data: ";

		  if (buff[0] != '6' || buff[1] != '6' || buff[2] != '6')
			 send(exp,buff,sizeof(buff),0);
		  else
		  {
			 send(exp,buff,sizeof(buff),0);
			 closesocket(exp);
			 cout << "--- Session closed." << endl;
			 WSACleanup();
			 exit(0);
		  }
	   }
    }
}

void server()
{
    SOCKET imp;

    if (imp = socket(AF_INET,SOCK_STREAM,0))
	   cout << "--- Receiving socket created successfully." << endl;
    else
    {
	   cout << "Can't create receiving socket. Aborting." << endl;
	   WSACleanup();
	   exit(0);
    }

    sockaddr_in addr;

    addr.sin_family = AF_INET;
    addr.sin_port = htons(5656);
    addr.sin_addr.s_addr = htonl(INADDR_ANY);

    if (bind(imp,(LPSOCKADDR)&addr,sizeof(addr)) == SOCKET_ERROR)
    {
	   cout << "Error binding. Aborting." << endl;
	   WSACleanup();
	   exit(0);
    }

    if (listen(imp,1) == SOCKET_ERROR)
    {
	   cout << "Error listening. Aborting." << endl;
	   closesocket(imp);
	   WSACleanup();
	   exit(0);
    }
    else  
    {
	   SOCKET client;

	   client == accept(imp,NULL,NULL);

	   if (client == INVALID_SOCKET)
	   {
		  cout << "Can't accept connection. Aborting." << endl;
		  closesocket(imp);
		  WSACleanup();
		  exit(0);
	   }

	   else 
	   {
		  cout << endl;
		  char buffer[maxchars];

		  while(buffer[0] != '6' || buffer[1] != '6' || buffer[2] != '6')
		  {	 
			 buffer[0] = 6;
			 buffer[1] = 6;
			 buffer[2] = 6;
			   
			 recv(client,buffer,sizeof(buffer),0);
		 
			 if (buffer[0] != '6' || buffer[1] != '6' || buffer[2] != '6')
			 {
				if(strlen(buffer) > 0)
				    cout << "Message Received: " << buffer << endl;
			 }
			 else
			 {
				closesocket(imp);
				cout << "--- Session closed." << endl;
				WSACleanup();
				exit(0);
			 } 
		  }
	   }

    }
    
}

void main()
{
    
    WSADATA w;

    if(WSAStartup(0x0202,&w))
    {
	   cout << "Can't initialize WinSock. Aborting." << endl;
	   exit(0);
    }
    else
	   cout << "--- WinSock initialized successfully." << endl;

    if (w.wVersion != 0x0202)
    {
	   cout << "Wrong version. Aborting." << endl;
	   WSACleanup();
	   exit(0);
    }
    else
	   cout << "--- Version 2.2 accepted." << endl << endl;


    int o = 1;
    while (o != 1 && o != 2 && o != 3);
    {	   
    	   cout << "1 - Run Server" << endl;
	   cout << "2 - Run Client" << endl;
	   cout << "3 - Exit" << endl;
	   cout << "Enter 1,2 or 3: ";
	   cin >> o;
    }
		   
    switch(o)
    {
	   case 1:
		  server();
		  break;
	   case 2:
		  client();
		  break;
	   case 3:
		  exit(0);
		  break;
    };		
}

When I connect to the server with the client the only message thats repeated constantly in the server is this:

Message Received: ♠♠♠⌂≈

Outline the design via pseudo. You posted arbitrary code.

Kuphryn

Code:

<client function>
	create object of SOCKET, exp
	determine socket descriptor, assign to exp
	create object sockaddr_in, target
	assign target values
	connect
	enter data to be sent
	send data to server(exp)

<server function>
	create object of SOCKET, come
	determine socket descriptor, assign to come
	create object of sockaddr_in, addr
	assign addr values
	bind
	listen
	create object of SOCKET, client
	assign client value returned by accept
	recv message
	display message

<main function>
	Initialize WinSock2.2
	Display list: client,server,or exit
	enter data, then run appropriate function

Thanks, so its an error with recv...

Gives me a start, thanks again.
