title: C# transparent winform, capture what is seen through window
body: <p>For a basic personal interest project, I'm trying to make a <strong>C# winform</strong> which is a screen capture device, I want to be able to resize a transparent window, press a button on keyboard and the program save what it can see transparently through itself to a file.</p>
  
  <p>All I need help with is a non-hacky way to <strong>get the image of what can be seen through the transparent window</strong>.</p>
  
  <p>A quick mock up in ms paint: <a href="http://i47.tinypic.com/2eam1iv.png" rel="nofollow">Mock up image</a></p>
  
  <p>Any help would be appreciated.</p>
