title: Alternative to GetClientRect?
body: <p>I am monitoring DirectX application that is in windowed mode on Vista. GetClientRect reports correct size until application is minimized and restored then it always returns the preview size (106x160).</p>
  
  <p>Is there any other way to query window for client area than use GetClientRect WinAPI? Perhaps sending message to the window, or checking what Windows knows about window client area?</p>
  
  <p>Any help would be appreciated and if you can use C# or .NET it would be a bonus but any other language would do</p>
