Messages from sub-components within components.

Hi All,

I am trying to create a component which is a container with 2 Linked
list boxes in. Whatever happens to one list box must happen to the other
( except the lists are different).

The problem is that I am unsure as to how I go about trapping for Scroll
messages on the list boxes.

Does anyone know of a good reference on messages in Delphi and windows?

Thanks.

Kind regards
Andrew Higgs
