Code error (socket prgm)

Hi guys,
I've tried the socket programming for the first time a very simple one, however I encountered some problems...
here's the code...
====================

Code:

#include <stdio.h>
#include <winsock.h>
#include <iostream.h>
void main()
{
	afxsocketinit();
	int nRet,sd=0;
	int port_to_connect_to = 5555; //port no.
	short nPort;

	Csocket.socket;

	socket.create();

	if(!socket.Connect(10.1.3.40,5555))
	{
	  int err = socket.GetLastError();
	  cout << err << endl;
	}

}

=========================================

Gives me the following errors!!
est_wskp2.cpp
C:\C++\IP2\Fe96_vp\Test_wskp2.cpp(11) : error C2065: 'afxsocketinit' : undeclared identifier

===========================================

Please can some one help me out with this!!
Basically its to do with making a connection to a server on a port.
If the return code is -1 the connection failed else success

Many Thanks!

I haven't used asfsocketinit(), but MSDN says it's declared in "Header file: Declared in Afxsock.h"

>Csocket.socket;
What's this?

>void main
main returns an int, so use int main().

Try that for starters.

And please use code tags.

why not just use the plane old SOCKET structure instead of your fancy Csocket's?

In the furture please use Code Tags. People will be much more likely to help you if you do. And they'll be happy about it

Inluding the proper header file should get you further down the road.

I am also playing with some network programming, and I have found that it is MUCH easier if you derive a class from CSocket. It has built in funcitons that are called when data is received on your socket. If you don't use a derived class, you will constantly have to check the stream to see if there is data waiting. By deriving a class from CSocket you can overide the OnReceive() function and execute the proper code there.
