title: SendMessage not working for windows 8 metro apps using win32 lib
body: <p>I already know how to minimize any desktop app window from my win32 app in vc++ using SendMessage(). But it fails if that window is of Windows store app(Metro App). So which API to use for minimizing any windows store app window.
  And it is different from the other question(<a href="https://stackoverflow.com/questions/7465517/how-can-a-metro-app-in-windows-8-communicate-with-a-backend-desktop-app-on-the-s">question</a> because i am writing only desktop app. I just want a code to minimize any metro app window using vc++ win32 lib. And other question is about IPC between two apps where both apps are being written by us.</p>
