A class with event handlers for TCP, UDP or ICMP sockets; includes ping, traceroute, whois, ARP, and IPHelper functions and raw packets forging/ capturing.

Because of errors between VS 2002 and 2003, I've decided to put the two projects to solve resx and obsolete warning troubles.

Sample Image - networkstuff.jpg


This code contains a class for socket: ICMP, TCP, UDP, raw TCP, raw UDP, raw IP, and a class for IPHelper functions. All the classes for socket are made with the same view: provide handler for events like connected, closed, closed_by_remote_side, data_arrival, error ....

The sample project is included in beta version, it provides a graphical interface for Telnet, ping, traceroute, whois, packet capture, packet forging, scanning, viewing stats (IPHelper sample), sending ARP, DNS, wake and shutdown on LAN.

How to use

See the following sample for TCP:

easy_socket.tcp.Socket_Data clt;
clt=new easy_socket.tcp.Socket_Data();

// add events
clt.event_Socket_Data_Closed_by_Remote_Side+= new 
clt.event_Socket_Data_Connected_To_Remote_Host +=new 
clt.event_Socket_Data_DataArrival +=new 
// connect

// handlers
protected void 
    socket_closed_by_remote_side(easy_socket.tcp.Socket_Data sender, 
    EventArgs e)

  // handler code

protected void 
    socket_connected_to_remote_host(easy_socket.tcp.Socket_Data sender, 
    EventArgs e)
  // handler code

protected void socket_data_arrival(easy_socket.tcp.Socket_Data sender, 
                         easy_socket.tcp.EventArgs_ReceiveDataSocket e)
    string strdata=System.Text.Encoding.Default.GetString(e.buffer, 
                                                0, e.buffer_size );

protected void socket_error(easy_socket.tcp.Socket_Data sender, 
                         easy_socket.tcp.EventArgs_Exception e)
    string strerror=e.exception.Message;

As you can see, you can save a lot of time using these classes.

No, it's got nothing to do with stealing code. I head up two open source projects that are released under the Apache License. They're free. Because of GPL licensing, though, I can't use any GPL code in my free projects. Would you claim that the Apache projects aren't in the spirit of open-source?
Most Code Project visitors work for companies that have internal applications. They don't sell these applications - they're purely to support their business. GPL code requires that you release your code for all...something that causes problems when you're dealing with intellectual property issues.
I'd strongly recommend publishing it under the LGPL or something more flexible like the BSD, MIT or Apache licenses.
I'd like it if Code Project didn't allow GPL code, since it's too restrictive.
