Integrating GCC MinGW with Eclipse IDE

Recently, i need to work with C/C++ projects which i’ve never done it before in my job. I was working with HTML5/Javascript using Eclipse as it’s the Smart TV main IDE. I always know that Eclipse is a good guy and it should be able to do C/C++ development since i’ve seen C/C++ developer edition in download page, now the challenge is how to make my current eclipse (Smart TV IDE) able to compile and run the C/C++ codes.

Counting Size of Struct in C

First, i didn’t guarantee that this post will give a true answer for any problem because this conclusion just made by myself based on my observation on some codes. It’s very welcome to give another opinions or answers to share more knowledge and better solution.

This post will discuss about how much a struct take a memory? because of structs is a user-defined data structures, it’s size will be relative to the content that the struct stores. For beginning let’s refresh our memory (brain) about two most-used primitive data types size.

  1. int (4 bytes / 32 bits)
  2. char (1 bytes / 8 bits)

Writing Object to XML using XmlSerializer C# Source Code

How to write an object to a file with XML format? There is a class from .NET System.Xml.Serialization.XmlSerializer which can help to completely serialize the objects from program to a XML formatted files.

Suppose that we want to save the data of a person which has attributes:

  1. Name
  2. Age
  3. Height
  4. Weight

And the Person class:

public class Person
{
    public string name;
    public int age;
    public int height;
    public int weight;

    public Person() { }

    public Person(string name, int age, int h, int w)
    {
        this.name   = name;
        this.age    = age;
        this.height = h;
        this.weight = w;
    }
}

Simple HTTP Proxy Server C# Source Code

This time my next step for building the M-NIC Projects, creating a HTTP Proxy Server which is actually just an HTTP Relay :D. The concept just take everything from applications which HTTP Proxy server is set to my application then relaying the request to the destination server then relay again the response from destination server to client application.

The method? Just ordinary Socket Programming in C# (System.Net) Socket.Send(), Socket.Receive(), etc. First let’s take a look to the Server Listener, every server must listen to the incoming client connection. In this application, i’m using TcpListener for that.

using System.Net;
using System.Net.Sockets;

namespace SimpleHttpProxy
{
    class ServerListerner
    {
        private int listenPort;
        private TcpListener listener;

        public ServerListerner(int port)
        {
            this.listenPort = port;
            this.listener = new TcpListener(IPAddress.Any, this.listenPort);
        }

        public void StartServer()
        {
            this.listener.Start();
        }

        public void AcceptConnection()
        {
            Socket newClient = this.listener.AcceptSocket();
            ClientConnection client = new ClientConnection(newClient);
            client.StartHandling();
        }

    }
}

How it works? See the main method implementation below. Just initiate server listener object which is listen to port 9000 (this port number is up to you, but make sure you’re choosing free port number), then start the server to make the server ready to accept incoming connection and do the magic loop (actually just an infinite looping) to accept the incoming connection.

Get All Local Network Interface Card (NIC) C# Source Code

Yeah, actually i’m back to blogger activities… This is the part of my next projects, M-NIC Projects. The goal is to get all information of our network interface card (NIC) information such as IP addresses, link speed, name, etc. So after doing some head-to-head within some programming languages, my choices is C# .NET, because i think it’s easiest way to get that. The result is something like below, i retrieve all of my NIC which status is UP

Name            : Wireless Network Connection 2
