you need to move the execution to another thread. Do the following:

  1. Show the 'Processing' Message
  2. Spawn another thread to perform your calculation
  3. When the thread completes processing it should trigger an event in the main thread
  4. As a part of the event handler replace the "processing' message with the "Completed' message
