AFX_DATA

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_DATA is used to mark the beginning and end of member variable declarations in your header file (.H) used for dialog data exchange (DDX):

//{{AFX_DATA(classname)
...
//}}AFX_DATA
