you misunderstand typename. it must be used at each usage of the
type-dependant type. I.e. either [untested code coming up]

template <class LB> class C
{
public:
	typedef typename LB::DataType DataType;
	void FillBox (DataType &);
}
template<class LB> void C<LB>::FillBox(DataType &info)
{
        ;
}

or
template <class LB> class C
{
public:
	void FillBox (typename LB::DataType &);
}
template<class LB> void C<LB>::FillBox(typename LB::DataType &info)
{
        ;
}
