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.

Sorry, I realize that I did not provide you with any decent resources to help aim you in the right direction, should you so choose to look into my suggestions.
Here's link that will provide you with best practice guidelines for naming conventions and a host of other coding topics. Whether you agree with my thoughts or not, this will help you to understand my perspective.
Ps. I dig your efforts, and I gave you 5 regardless of not reading your update. I have read your code in the past, and you demonstrated a good working knowledge of a host of networking topics. And, simply because I love all efforts in network programming! Keep coding! This thread is merely a suggestion on formatting, not a flame!
Only those who attempt the absurd, can achieve the impossible.
