ClassWizard Comment Delimiters 
  In order for ClassWizard to distinguish between code entered by the user and code created by ClassWizard, several types of special delimiters are used. These delimiters are formatted to appear as comments in the code. Therefore they are never compiled or modified by anything except ClassWizard. 
 
  The following is a list of the ClassWizard comment delimiters. For more information, see the topics in this section.
