title: Custom window minimize animation
body: <p>I am developing a taskbar for the seconds screen and can't get this thing to work..</p>
  
  <p>When I minimize an application on the seconds screen it will show the minimize animation to the main screen (vista &amp; 7 aero). What I am trying to do is show the animation to my own taskbar on the seconds screen. I know it is possible because Displayfusion and Acual Multi Monitor also have this feature. So after a bit of research I discovered that you can set the minimize position with the SetWindowPlacement API. However, I can't get this to work. The window will still show the minimize animation the the main screen.</p>
  
  <p>This is what I have tried so far: First hide the taskbarbutton of the window that is on the second screen with ITaskbarList DeleteTab method. Then I use this function to set the minimize position and minimize the window:</p>
  
  <pre><code>public void ShowHideAnimated(IntPtr Handle, Boolean show)
          {           
              WINDOWPLACEMENT wp = new WINDOWPLACEMENT(); 
              GetWindowPlacement(Handle, out wp);
  
              wp.length = Marshal.SizeOf(typeof(WINDOWPLACEMENT));
  
              wp.flags = WPF_SETMINPOSITION;
              wp.ptMinPosition.X = -500; //(-500,200) is a point on the second screen
              wp.ptMinPosition.Y = 200;
  
              if (!SetWindowPlacement(Handle, ref wp))
              {
                  Debug.WriteLine( Marshal.GetLastWin32Error() );
              }
  
              if(!show)
              {            
                  ShowWindowAsync(Handle, SW_MINIMIZE);
              }
              else
              {
                  ShowWindowAsync(Handle, SW_RESTORE);
              }                 
          }
  </code></pre>
