You should put that file in every PRG, Form, Class file that was created BEFORE you add this file in project (of course if you need to).
I don't know why but that is the MS decision :-)
But have:

#include [full path to H]SomeHFile.H

** code here

and than get an error? I never saw this.
Be careful, VFP is not a strong typing language. Compiler didn't raise errors when it saw not defined variables. So it threads FCREATE_READWRITE as a variable that shoulw come from some other module (like private or public variable).
