title: WS_EX_LAYERED windows does not move with respect to its parent window
body: <p>I have created a window which has WS_EX_LAYERED extended style.
  After that I changed parent of this window as acall to SetParent.
  But When I move parent window on desktop my window is not changing its position with respect to its parent.</p>
  
  <pre><code>int translevel = 50;  /* 0 - 255 */
        SetWindowLong(m_hWnd,GWL_EXSTYLE,GetWindowLong(m_hWnd,GWL_EXSTYLE)|WS_EX_LAYERED );
        ::SetLayeredWindowAttributes(m_hWnd,RGB(0,0,0),translevel, 0x02);
  
        HWND hParent  = ::FindWindow(TEXT("TSSHELLWND"), NULL);
  
        ::SetParent(m_hWnd, hParent);
  </code></pre>
  
  <p>Note:- TSSHELLWND is the mstsc session window. I would like to make my window as a child of mstsc session window.</p>
  
  <p>Is it not moving because I applied LAYESRED attribute on a child window????</p>
