thanks for answer, but what i mean with my question was the syntax use of
#define DECLARE_MESSAGE_MAP ...etc
i don't know if it means that

private: \

static const AFX_MSGMAP_ENTRY _messageEntries[]; \
protected: \
static AFX_DATA const AFX_MSGMAP messageMap; \
static const AFX_MSGMAP* PASCAL _GetBaseMessageMap(); \
virtual const AFX_MSGMAP* GetMessageMap() const; \

will be replaced every time in the program is DECLARE_MESSAGE_MAP as if it
was a constant or if the function block operate like a macro called by
DECLARE_MESSAGE_MAP...

I know about 2 uses of #define:

1: declaring costant
#define max 100
2: declaring macros
#define swap(x,y,z) (z=x);(x=y);(y=z);

i don't see any of those uses looking at DECLARE_MESSAGE_MAP...
i'm maybe ignoring something ?

DECLARE_MESSAGE_MAP is a macro. It is replaced with the lines of code
each place that it appears in the program. This is exactly like
#define max 100
except the "100" part is several lines of code.
