body: <p>I want my <code>ProgressBar</code> starting in some point in my code and run total of seconds until my file finish, and of course I know how long the run of my file will take.
  I try to read on MSDN but I did not understood how to use it.</p>
  
  <p>My application run files (wireshark file, send the packet using bittwist) and each file will run few seconds and I want the option to see the progress ongoing.</p>
