Using directives in Resource File

I am using the directive   "#if defined(MACHINING_CTR)" in the resource (.RC) file.  If I put a "#define MACHINING_CTR" command in the .RC file then the #if directive works correctly.  However if instead of using the "#define" statement, I define the MACHINING_CTR as a Preprocessor Definition then the "#if" directive does not work.  Does the resource file not recognize Preprocessor Definitions?

>>>> Does the resource file not recognize Preprocessor Definitions?
No, the resource file was compiled by the resource compiler (rc) and not by C++ compiler which firstly invokes the C/C++ precompiler.

You can add directives for the rc when opening the resource file and go to 'Edit - Resource Includes ...'. Here you have two multi-line edit boxes where you could add #include or #define statements. Or you use global environment variables which should work as well.
