C++ vector<T> where T is a struct inside a class

I have a class that looks like this:

template<typename T>
class MyContainer
{

public:

    struct Handle
    {
        public:

            T* Resolve();
    };

private:

    vector<Handle> mHandles;

};

It seems like they won't compile the iterator for the handles when I am using:

vector<Handle>::iterator iter = mHandles.begin();

If I change it to auto it works:

auto& iter = mHandles.begin();

Am not suppose to use the type explicitly?

vector<Handle>::iterator is a dependent name, hence you must include a typename before it, when you use it inside a template function/class

Simply change

vector<Handle>::iterator iter = mHandles.begin();

to

typename vector<Handle>::iterator iter = mHandles.begin();

will work.
