How to debug macros efficiently in VS?

Question

I\'ve got a pretty complicated macro inside my (unmanaged) C++ code. Is there any way to expand macros in VS debugger? Or maybe there is another way to debug macros there?

I learned from http://www.codeproject.com/Tips/320721/Macro-expansion-in-VCplusplus the best way to debug macros.

And what i do is to create a cxx file named "test.cxx" and inside i only put the macro and a some uses example of a test.cxx:

#define GetMacro(param1) \
  public: void Get##param1(){ return m_##param1; }

GetMacro(MyVariable);

and in a command line i enter:

c:\ cl /EP test.cxx > output.cxx

When i open the output.cxx file there should be some blank lines and at the bottom the expanded macro, like:

public: void GetMyVariable(){ return m_MyVariable; };

You can test macros without compiling and that makes it quick.
