this problem is caused by several #defines in windows.h and other header
files like:

#ifdef _UNICODE
#define GetObject GetObjectW
#else
#define GetObject GetObjectA
#endif

so your code gets preprocessed to
resources->GetObjectA instead of
resources->GetObject

solution is to undef the offending define like
#undef GetObject or
#define GetObject GetObject
