Amen! And this is an extremely important point. With the "RAD" (which really should be called RUID) tools like Delphi, BCB, VB etc. it's way too easy to intermingle your GUI and core logic, and this becomes really messy. Keep your "OnClick" (etc.) routines simple, calling into separate modules.

I've gotten burned on this one myself.  Just because it looks like a duck, walks like a duck, & quacks like a duck ... Doesn't mean it's a complete duck.
