<div class="markdown level1 remarks"><p>
     All messages are sent to the <b>WndProc</b> method after getting filtered through the <a class="xref" href="https://learn.microsoft.com/dotnet/api/system.windows.forms.control.preprocessmessage">PreProcessMessage(ref Message)</a> method.
     </p>
<p></p>
<p>
     The <b>WndProc</b> method corresponds exactly to the Windows WindowProc function. For more information about processing Windows messages, see the WindowProc function documentation in the Windows Platform SDK reference located in the MSDN library at http://msdn.microsoft.com/library.
     </p>

  <b>Notes to Inheritors:</b> Inheriting controls should call the base class's <b>WndProc</b> method to process any messages that they do not handle.
