please give me some advices.

I get a compile error,when to index on base class member.

the codes are listed below:

struct Foo { int a; };

struct Bar : public Foo { int b; }; <snip> member < Bar,int,&Bar::a> <snip>

Error 1 error C2440: 'specialization' : cannot convert from 'int Foo::* ' to 'int Bar::* ' and the codes are compiled in boost 1.40, vs 2008 sp1

You can use the base class in member: member<Foo, int, &Bar::a> In Christ, Steven Watanabe
