Event COM client C++

[Albuquerster]

Hi,
I need to develop in C++ event handling of a COM object. I imported the .tlb file and noticed the following definition in the .tli file:

//
_IEvnt: Idispatch
{
HRESULT OnFire ();
};

Question: What instructions should I program in C ++ to receive this event in the client code?

Thanks
