at the moment I try to get access to winRT's geolocation class. This is essencial for me essential, to get GPS data without using serialports. Unfortunately this is not well documented. I'm not a pro c++ developer and more common with c#. I already used c++/cx but because some properties has to be set in the settings which i cannot do from code or with my qt .pro file I have to find an alternative.
C++/CX classes are actually just syntactic sugar that hides away an ugly COM interface. You may access those classes via COM, however it isn't technically "supported."
