ATL Basics

Hey all,

I'm trying to write some simple ATL stuff. I've never used ATL before
and it's been several years since I've used C++, so I'm just a little
rusty... :) I have a class that's using a CAutoPtr and CAtlArray.
The class looks something like the code below. Is this the correct
way to use the ATL stuff? My code is working (thankfully), I just
want to make sure I'm things the right way and cleaning everything up
correctly. Thanks in advance!

class SimpleClass
{
public:
    SimpleClass()
    {
        classA *cA = new classA();
        m_pClassA.Attach(cA);

        classB *cB = new classB();
        m_pClassBArray.Add(cB);
    }

    ~SimpleClass()
    {
        for (int i = 0; i < m_pClassBArray.GetCount(); i++)
        {
            classB *cB = m_pClassBArray.GetAt(i);
            delete cB;
        }
        m_pClassBArray.ReleaseAll();

        // m_pClassA is automatically taken care of
    }

private:
    CAutoPtr<classA> m_pClassA;
    CAtlArray<classB *> m_pClassBArray;
}
