Examples working for M5 dart version!

• When clicking on any column, we don't see any feedback it was clicked
• No filter applied when clicked on column anyway

1. Listen music that make you happy. It does not really matter what music it is. The key is, it does make you feel great!

2. Surround yourself with those kind of people. Let sad and crying people disappear from your life. Connect to happy and active people. Collaborate. Sometimes their look or smile or small talk will give you push to the right direction.

3. Be proactive. Turn TV/PC off. Go walk on the fresh air. Any routine action we produce, put us on specific track were we stop thinking and doing mechanical actions. Stop live by inertia.

4. Do something different/exceptional. It means be also open minded! To think different, to considerate, to take view of another person.

1. Close button in every window is located in the upper left corner. Its quite annoying especially after years working with close button located on the upper right corner. I am not really need it, since i working with shortcuts a lot, but still.. It just annoying :)
2. Menu bar on the desktop is looks reversed. In English version task-bar clock should be on the bottom left side, where in Hebrew version it located on the bottom left. Annoying as well.
3. Main GUI in Windows 8. In English version groups of icons arranged automatically from left to right, were in Hebrew version it quite opposite. Super annoying!

Points of Interest 

1. 1. CLR (Common Language Runtime) transform our code into MSIL (Microsoft Intermediate Language).
2. 2. CLR compile MSIL into platform-specific code.
3. 3. In case we run program, MSIL turns into machine code by JIT.

using (TextWriter w = File.CreateText("log.txt"))
{
    w.WriteLine("This is line one");
}

    
    bool flag;
    TextWriter w = File.CreateText("log.txt");
    try
    {
        w.WriteLine("This is line one");
    }
    finally
    {
        flag = w == null;
        if (!flag)
        {
            w.Dispose();
        }
    }

  for (int i = 0; i < 3; i++)
  {
     Console.Write(i);
  }

    bool flag;
    int i = 0;
    while (true)
    {
        flag = i < 3;
        if (!flag)
        {
            break;
        }
        Console.Write(i);
        i++;
    }

Create Console Application and put following code in Main() method and press F5:

using (TextWriter w = File.CreateText("log.txt"))
{
    w.WriteLine("This is line one");
}

Now press Open button in JustDecompile and then File(s) and choose exe file from project you just build (usualy can be found in  ..... /Bin/Debug/) Expand left panel of the  JustDecompile application as shown and you will see the desired result:
