Class and template questions

I've got a bit of code that looks something like this:

Code:

template <typename T>
class A
{
private:
	class B
	{
	public:
		B() { count = 0 }
		T data;
	private:
		unsigned int count;
		friend class A;
	};
public:
	A();
	B* do_stuff(T some_data);
};

template <typename T>
A<T>::B* A<T>::do_stuff(T some_data)
{
	B* temp = new B;
	temp->data = some_data;
	++(temp->count);
	return temp;
}

The highlighted bit is where I'm stuck. I get the error:

'A<T>::B' : dependent name is not a type

I think I'm on the right track, but now I'm totally lost. Any advice?

On a related note, in main() I'm looking to create a vector of B*. Is there any way of me doing that without having to declare the whole mess public? I want to do this:

Code:

int main()
{
	A<int> MyClass;
	vector<A<int>::B*> my_vector;
	for(int i = 0; i < 10; ++i)
	{
		my_vector.push_back(MyClass.do_stuff(i));
	}
	return 0;
}

However, I don't want to whole world access to anything inside of B. What am I forgetting to do?

Try "typename A<T>::B*" instead of "A<T>::B*" on the line in question

Ah, works like a charm. Thank you.

Any ideas about the last part?
