<div class="markdown level1 remarks"><p>All messages are sent to the <b>WndProc</b> method after getting filtered through the PreProcessMessage method.</p>
<p></p>
The <b>WndProc</b> method corresponds exactly to the Windows <b>WindowProc</b> function. For more information about processing Windows messages, see the <b>WindowProc</b> function documentation in the Windows Platform SDK reference located in the MSDN library at http://msdn.microsoft.com/library.
<p></p><b>Notes to Inheritors:</b><p></p>
Inheriting controls should call the base class's <b>WndProc</b> method to process any messages that they do not handle.
