Remarks
ClassWizard and AppWizard insert specially formatted comment delimiters in your source code files to mark the places in your files that ClassWizard can write to. AFX_DISP_MAP is used to mark the beginning and end of OLE Automation mapping in a class’s implementation (.CPP) file:
//{{AFX_DISP_MAP(classname)
...
//}}AFX_DISP_MAP
