How can I work this out? I've tried with auto_ptr<object> but its copy-constructor is explicit and didnt worked anyway. (MSVC71). What I wanted is a vector of variant and I dont want object1 and object2 to be copied because it is expensive. But Im not figuring out how to do this... tried boost::ref either with no success... :/ Any information is appreciated, thanks in advance, Felipe. -- Felipe Magno de Almeida Developer from synergy and Computer Science student from State University of Campinas(UNICAMP).
