Aggregation Mini-Lecture: Day 1
You've been asked by your local veterinarian to write a program for pet owners to help them know how to care for their new pets. The owner will select the type of pet and the type of care, press OK and they will be told what to do. You ask a few questions, find out that the vet only deals with cats and dogs, and go off to write the program.

You compile and test and it works great! You're ready to package it up for the vet, but then you remember what you learned in your VB courses, oh, yeah, I'm not supposed to code everything in the form. That's right. Hmmm. I'm supposed to use a separate class module in case I want to reuse this code later on. Or if I need to fix a bug...that way I can just issue a service patch instead of reinstalling the whole program...
