title: Why "@echo off" is not making a difference?
body: <p>In a .bat file like this :</p>
  
  <pre><code>@echo off
  start C:/my_test.exe
  </code></pre>
  
  <p>Why the first line is making no difference ? I thought with "@echo off", it won't open the command window, but it still flashed and then closed, it has the same effect as without the first line. How to avoid the command window to open at all ? In other words, how to write the .bat file, so that when it runs, ONLY my exe file opens, the Windows command prompt window won't show up at all.</p>
  
  <p>I want the app to run at start up, so I was told to create the bat file and put it in the Start up folder, so to not having the command prompt window show up at all, I was suggested to create a short cut, how to create a short cut and save it in the start up folder, I need to do it from my app, what does the DOS command look like ? It need to first find where the start up folder is, then create and save the shortcut in the start up folder.</p>
