title: Please explain the late binding process
body: <p>I'm trying to make a simple addin. The developers documentation states this:</p>
  
  <blockquote>
    <p>Late bind to <strong>ETABS.exe</strong>, create an instance of the <strong>ETABSObject</strong>, and get a reference to the <strong>cOAPI</strong> interface.</p>
  </blockquote>
  
  <p>I'm very confused on how to late bind to an already running exe. If you could give me an example or point me in the right direction I would really appreciate it. I've been banging my head on wall for days.</p>
