title: How to release the occupied memory
body: <p>I have a main window in my project, and numerous other child widows inside the main.<br>
  I have noticed that. When I open the main window occupies 1500K of memory, when open one child window then adds in occupied memory 6000K.<br>
  When I open the second window doing the same. When I close the two child windows the occupied memory is not released.<br>
  So What I want is to release the occupied memory when ever I close child windows.<br>
  How I can do that?<br>
  Please advice me with some code example in vb.net if it is possible.<br>
  This problem often sawing in the computers on the Local NET not in my computer (developer computer which has the SQL server on it).   </p>
