I'm working with existing code, where I've found that I have to modify some #include preprocessor directives. For example, to change
I include the original line in a comment just above the changed line:
/* #include "myhdr.h" original */ #include "..\hfiles\myhdr.h"
When I do this, some subsequent preprocessor lines appear grayed-out. It doesn't always occur, and it's not consistent. I've tried to find what this means by searching the MS help, which triggered an error in their search engine. Can some kind soul please provide a clue as to what it means, and what might be going on?
