title: C# WinForm - loading screen
body: <p>I would like to ask how to make a loading screen (just a picture or something) that appears while the program is being loaded, and disappears when the program has finished loading.  </p>
  
  <p>In fancier versions, I have seen the process bar (%) displayed.  how can you have that, and how do you calculate the % to show on it?</p>
  
  <p>I know there is a Form_Load() event, but I do not see a Form_Loaded() event, or the % as a property / attribute anywhere.</p>
