Cheers for that, This will indeed show the include heiarachy, which is a great place to start for a manual search. The problem is I was looking for something a little more complex. What I would like is a tool that would look at the include files listed in a CPP and indicate if the included file is actually not needed. Or where a header is included in another header where a predeclaration could be used instead. i.e. #include "cBar.h" class cFoo { cBar *mValue; } Should be... class cBar; class cFoo { cBar *mValue; } DAve
