title: What's a nice way of building a wParam or lParam in C#? (Something friendlier than shift operators?)
body: <p>When the WIN32 docs says something like:</p>
  
  <pre><code>wParam
      The low-order word specifies the edit control identifier.
      The high-order word specifies the notification message. 
  </code></pre>
  
  <p>What's a nice way of building that wParam?</p>
