A development tool has to support these 3 concepts before it can be called OO: encapsulation, polymorphism and inheritence. Since VB 6 lack the third one, it is called Object Based and not OO.

RaiseEvent and early binding are great tools, but they are not part of the OO concept.

VB 7 look very impressive indeed (inheritence, strong typing, etc.) I will surely use it more often as a front end and keep VFP for the middle tier. I will also take a good look at the new C# which give me a good impression.
>VB has some great features that makes it nice for building OO apps. Like RaiseEvent, typing, early binding and multiple interfaces. But trying to get inheritance is painful. (Using hooks is not inheritance ... dBase for DOS can implement hooks.) Hopefully VB7 will silence the laughter when you mention 'VB inheritance' to developers using other OO languages.
