[Boost-users] lexical_cast question

Hello, I have implemented the following template: template<typename Value> struct Validator { typedef bool result_type; bool operator()(const std::wstring& newVal)const { boost::lexical_cast<typename Value>(newVal); return true; } }; now here is the problem that for pointers the lexical cast doesn't work. I have now made the following declaration: boost::lexical_cast>::type>(newVal); It works now for pointers too, but now I have the problem with the char type. First I have made a specialization for this type. Is it here also possible to make only one specialization or have I to provide both for pointer and value? Is there another way to solve that problem? best regards Hansjörg
