title: Differences between Excel's Form Controls & ActiveX Controls
body: <p>Why are there <strong>2 types of controls</strong> available in Excel?  <em>(2 buttons, 2 combo boxes, 2 check box, etc...)</em></p>
  
  <p>What's the difference between  <strong>Forms Controls</strong> and <strong>ActiveX Controls</strong>?  Which one should I use?</p>

  <p>Some code samples I find online work with my controls, but others do not.  How come?  </p>
  
  <p>How do I work with each type, and how can I tell the difference? </p>
