I have some C++ code that includes a method called CreateDirectory(). Previously the code only used STL and Boost, but I recently had to include <windows.h> so I could look-up CSIDL_LOCAL_APPDATA.

Now, this code:

filesystem.CreateDirectory(p->Pathname()); // Actually create it...

No longer compiles:

error C2039: 'CreateDirectoryA' : is not a member of ...

Which corresponds to this macro in winbase.h:

#ifdef UNICODE
#define CreateDirectory  CreateDirectoryW
#else
#define CreateDirectory  CreateDirectoryA
#endif // !UNICODE

The pre-processor is redefining my method call. Is there any possible way to avoid this naming collision? Or do I have to rename my CreateDirectory() method?

    You will be better off if you just rename your CreateDirectory method. If you need to use windows APIs, fighting with Windows.h is a losing battle.

    Incidently, if you were consistent in including windows.h, this will still be compiling. (although you might have problems in other places).
