Question

Is there any hack I could use to do this:

template <class TYPE>
class Hello
{
     TYPE _var;
};

I would like a way to store

Hello<int> intHello and Hello<char*> charHello

into the same Container such as a Queue / List.

No, because they are different and completely unrelated types.

You can, however, use inheritance and smart pointers:

class HelloBase 
{
public:
    virtual ~HelloBase(); 
}

template <class TYPE>
class Hello : public HelloBase
{
    TYPE _var;
}

std::vector<boost::shared_ptr<HelloBase> > v;

shared_ptr may be supported by your implementation either in the std::tr1 or std namespace; you’d have to check.
