One thing to remember when looking at "Samples", is that they are intended for illustrative purposes, and typically have the minimum amount of code necessaery to demonstrate specific functionallity.

In 99% of the cases, they are NOT indicitive of "Best Preactices" and are not "Production Quality" code. It is VERY VERY rare that you can copy/paste from a reference sample into a "real" program and have anything approaching a robust architecture and design.
