Before I wrote a single line of code or used a single component in my project I
identified:

1. the defaults I wanted for each of the components that are going to be used;

2. the behaviour that I wanted to be specific to the project at hand.

The purpose is to derive all components I use from existing components and
modify the defaults and behaviour to suit the project. I learnt this lesson in
other projects.

This is not only expected in an object-oriented environment, it is essential and
reduces development time and reduces the occurrences of bugs. Also, further
changes are more-easily incorporated.

Most components from nearly all of the multitude of component sets I will use in
the current project will be sub-classed.

Simple example:
I will one component that is specifically for read committed transactions and
another for table locking; there are also other changes required too.

You wouldn't believe what I've done to a ListBox component! (I cannot tell you
what it does, but there are an additional 15,000 lines of (non-blank) code.)
