>I've been thinking about this this morning. Who invented the zero based approach, which applies to a lot of things in several development environments, including, among others, .NET. This is always a waste of time trying to understand/find which one applies to a specific component. I mean, when I start counting, I start at 1, right? lol

Michel,

Think about it. You are starting at 0 when counting.

You have nothing.
you count 1
you have nothing + 1 = 1
Where did you start?
Nothing!

It is not what you count what matters it is what you have that matters.
