Get part of a bitmap ressource

Hi all,

What I want to do is to load a "big" bitmap ressource as a library, and then just take a part of it to display as an icon.

The goal is to have a "table" of icons, for exemple 10x10, to just load 1 bitmap ressource and not have to declare 100 ressources ...

An idea ?

Regards.
