title: WPF Fake Full Screen
body: <p>I have a project that automates/controls other Window applications by simulating keystrokes. To simulate keystrokes, I need to bring the window of that application to the front. When this is in progress, you can see the whole process on the screen. </p>
  
  <p>However, I want to have a fake full screen to cover that up. If this is possible, I would also like to display something on the fake full screen, such as the progress bar. </p>
  
  <p>Any suggestion would be helpful. Thanks</p>
