title: Message boxes (VBA): how can I include/use them in my Excel Macros?
body: <p>I'm teaching myself (read hacking) through some old Excel Macros that are quite long. However, as I change quite a few lines I want to be sure that I know when and where my new and re-hashed elements are occuring - or not. So my question/s is:</p>
  
  <ul>
  <li>How do I insert a simple message box function that will pop up when a loop/procedure/event has finished? </li>
  <li>Add text to it explaining what happened (hard coded ofcourse)? </li>
  <li>Also, include an "OK button" that makes it start the next procedure?</li>
  </ul>
  
  <p>The breakpoint process may be the most effective way of doing this, but I would like to use the message box approach so that I can show my colleagues what is happening. Also it would be something that I'd like to incorporate into future projects.</p>
  
  <p>Many thanks for any examples, links or helpful hints.
  Michael.</p>
