ComPtr for Visual Studio 2010

If you aren't using Visual Studio 2010, then you might like to use this class if your doing C++ and COM:

template <typename T>
class AutoPtr {
private:
    T* FData;
    
public:
    AutoPtr(T* Value) {
        FInterface = Value;
    }
    
    ~AutoPtr() {
        if (FData != NULL) {
            FInterface->Release();
        }
    }
    
    operator T* () const {
        return FInterface;
    }
    
    T&amp; operator* () const {
        return *FInterface;
    }
    
    T* operator->() const {
        return FInterface;
    }
    
    T** operator&() {
        return &FInterface;
    }
    
    T* operator=(const T * rhs) {
        FInterface = rhs;
        return FInterface;
    }
    
    T* operator=(const IUnknown * rhs) {
        FInterface = rhs;
        return FInterface;
    }
};
