title: Is there a Windows API hook for "this application wants attention"?
body: <p>In Windows XP, when a program wants the user's attention, it'll flash its taskbar button orange.  Anyone with an IM program is probably familiar with this behavior.  But when I'm playing a fullscreen-mode game, I don't see that, and messages go unanswered.</p>
  <p>Now I'm writing a game engine of my own, and I'd like to be kind to my users.  Is there any Windows API call I can write a hook for that will notify my program whenever any other program just set its taskbar button to &quot;orange flashing mode&quot;?  That way, I could notify the user when it happens.</p>
  <p>I'd be surprised if this isn't available.  I saw a Mac OS Classic screensaver that was able to do this way back in the mid-90s.  That's where I got the idea from.</p>
