re: The return value of a method can be intercepted using BindEvent

Thank you Clavin for your response :-) but, sorry, I'm not undarstanding :-(

In your previous post "What to do with the Bindevent return value?" you wrote:

"Event handlers handle events. They don’t have return values (...)."

and

"... that was changed for the released version of VFP9: the Return value of the original method is used. That way, the behavior is consistent and predictable. Also, adding a BindEvent to code won’t change the original author’s intended return value."

Something is not clear to me: may be the chages apply only when BindEvent() binds to a method and not to an Event (like Init, Keypress, MouseMove...) ?

Also in this post you write:

"... BindEvent is being used to bind to the Init event, meaning that the Return value is lost."

It is lost because overwritten by the last callede delegate return value, I'm right?
