I don''t understand why you need to use the preprocessor, when this does the same thing...
void BLAH(char* name){ cout << name;}
class IFactory {virtual void* create(ID id);};//Creation policyclass ICreationMethod {virtual void* create();};class SingletonCreation : public ICreationMethod {void* create() {//create as a singleton and manage as a singleton...}}template <class TYPE, class CREATION_METHOD>class FactoryItemCreation : public CREATION_METHOD<TYPEA>, public ICreationMethod {};template <class T>class Factory : public IFactory {void* create(ID id) {return (getCreationMethod.create());}ICreationMethod* getCreationMethod(ID id) {//find the creation method of id...}bool addType(ID id, ICreationMethod* pCreator){//insert new entry...}};quote:Original post by Erzengeldeslichtes
... and then within the CPP I can do the modifications on how to create the object from a string.

Hey, why not make a templated version of the factory?
like:
[snip]
Something like that, think its better than messing around with macros.
template<typename T> inline std::string nameOfClass() { return typeid(T).name();}class Factory { template<typename T> register() { register(nameOfClass<T>(),&T::create); }}
