Preprocessor directives from C++ code (_VARIADIC_MAX)

Question

Please how to define preprocessor directive _VARIADIC_MAX=10 from C++ code? For now I set it in Property Page -> C/C++ -> Preprocessor -> Definitions but I need it in each project. Will be cool to define it one time in some common.h file and use in every project by including such header.

Answer 1

You can do it like this:

#define _VARIADIC_MAX 10 

Answer 2

You can add this definition for current user throught user property sheet: Open one of your project, select View -> Property Manager. Then open property Microsoft.Cpp.Win32.user, and add your constant like earler (Common Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions). Save and restart visual studio.
