BOb,

>Perhaps I am missing something obvious, or not so obvious?

The concept I have in mind is outlined in Steve Black's article "Hook Operations" in the 08/97 issue of FoxTalk magazine.

In addition to using the simple hook methods that are currently implemented in the Framework, Steve discusses a more robust solution by greatly expanding the concept of hooks...hook objects, procedural hooks, data-driven hooks.

In the article, Steve outlines the pitfalls of using inheritance to solve the problem of extending the functionality of a class and provides a detailed explanation that it would take quite a while to explain in a single UT message!

After you take a look at the article, let me know what you think.

Regards,
