>>How do you define a handler for the undefined WM_ messages in straight VFP? Inquring minds and all that?

>Like you would with any other language, I suppose: you'd have to know what the messages are ahead of time. I guess I'm confused (easily done) as to how this would be an issue with VFP vs. C++. I mean, if I get something like WM_MYSPECIALMESSAGE, if it isn't documented what that integer is and I haven't accounted for it, it's just going to fall through the message loop in any language, right?

And how do you add VFP code to the loop to intercept a message that isn't currently handled by VFP's Event loop monitor? You need to add a handler to be dispatched, and without the ability to specify an entrypoint for dispatch on message receipt, you're kinda stuck - sort of like you were with VB4, before AddressOf() was a reality.
