title: Anchor buttons in a dialog when using SW_MAXIMIZE
body: <p>This should be a simple one:</p>
  
  <p>I have a CDialog with 2 buttons.
  The dialog is always opened in full screen (No title bar \ Status, etc...) using <code>m_pMainWnd-&gt;ShowWindow(SW_MAXIMIZE);</code></p>
  
  <p>I want my buttons to snap to the edge of the screen.</p>
  
  <p>There are no resizing or anything.</p>
