Inner or nested classes
-
GURU's only!:eek: I have a class "hidden" inside my main class, a kind of inner class if U like.
class a : public CObject { DECLARE_DYNCREATE(a) public: a(); class b : public CObject { DECLARE_DYNCREATE(b) public: b(); }; };But the IMPLEMENT_DYNAMIC macro expansion baffles the compiller's brainIMPLEMENT_DYNCREATE(a, CObject) IMPLEMENT_DYNCREATE(b, CObject)with the following messages: error C2653: 'b' : is not a class or namespace name error C2061: syntax error : identifier 'b' I have tried everything but write my own body for CreateObject() so I can get runtime class info, doingIMPLEMENT_DYNCREATE(a::b, CObject)Seems logical, but does not hel, since a is nit a namespace or so the compiller says.:( Conrad - conradb@adroit.co.za Always do badly to start off, that way when you get the hang of it suddenly, everyone is surprised. -
