title: How can I create a "Yes To All" Button using WinAPI?
body: <p>We have a legacy application written in C that uses WinAPI.  We'd like to add a "Yes to All" button to a few of our dialog boxes.  Unfortunately, the existing MessageBox function does not allow for custom buttons or button captions.</p>
  
  <p>What's the best way to do so?  Is there a slick hack to easily add a custom button?  Or should we create our own MessageBox replacement?</p>
