Hi,
If it's OK, I'd like to take this a little further. I was thinking
about my little chess move validation project. I thought I would sit
down and try to write out a little plan, because my book says that the
nouns become objects, but I started to get confused when I asked
myself this question. Do the pieces move, do the squares on the board
somehow get pieces, or does some controller in the sky move the
pieces? In the real world, the controller would be the player who is
moving the pieces. The pieces can't move them selves, and all the
board can do is sit there and have pieces on its squares. The rules
would be another object, would they not? Oh my head.

Hi,
I found this humorous.
Understanding the Parts of VBA "Speech"
If you were going to play soccer using BASIC, the instruction to kick
a ball would look something like
"Kick the Ball"
Hey---this is how we talk! It makes sense. You have a verb (kick) and
then a noun (the ball). In the BASIC code in the preceding section,
you have a verb
(print) and a noun (an asterisk). Life is good.
Here is the problem. VBA doesn't work like this. No object-oriented
language works like this. In an object-oriented language, the objects
(the nouns) are
most important (hence, the name: object oriented). If you are going to
play soccer with VBA, the basic structure would be:
Ball.Kick
You have a noun---the ball. It comes first. In VBA, this is an object
. Then you have the verb---to kick. It comes next. In VBA, this is a
method.
The basic structure of VBA is a bunch of lines of code where you have
Object.Method
Sorry, this is not English. If you took a romance language in high
school, you will remember that they used a "noun adjective" construct,
but I don't know
anyone who speaks in "noun verb" when telling someone to do something.
Do you talk like this?
Water.Drink
Food.Eat
Girl.Kiss
Of course not. That is why VBA is so confusing to someone who
previously stepped foot in a procedural programming class.
Let's carry the analogy on a bit. Imagine you walk onto a grassy field
and there are five balls in front of you. There is a soccer ball, a
basketball, a
baseball, a bowling ball, and a tennis ball. You want to instruct the
kid on your soccer team to
Kick the soccer ball
If you tell him kick the ball (or ball.kick
), you really aren't sure which one he will kick. Maybe he will kick
the one closest to him. This could be a real problem if he is standing
in front of
the bowling ball.
