title: slowly loading forms
body: <p>I've been writing a C# .NET application. i'm using WinForms.
  so, I've some forms that load really slowly especially due to the fact that they fetch some data from some XML files and display them in ListBox controls.</p>
  
  <p>What I'm asking is : how do I make the forms load faster. or how do I proceed to show some image of rotating wheel (the one you usually see when waiting for an action to be completed by a software).</p>
  
  <p>Thanks.</p>
