Enumeration vs making a list

[Willam Roberts]

To me, when you enumerate, you make a list of specific items, like
enumerating controls in a form. Am I missing something? I mean is there
something more to the meaning of the term "enumeratio n" or "enumerate" (in
programming context) other than just sounding technical. i.e. is it more
than just making a list of items? Are they the same thing? Please excuse my
'dah' factor, but it is really bugging me.

I don't agree with your opening sentence. To me, when you enumerate, you
**take an existing list** and go through it (i.e., count it) one line at a
time; you don't **make** the list. In VB, that definition broadens a little
bit. For example, you can enumerate the controls on a form using code
similar to this

Dim ctrl As Control
For Each ctrl In Controls
If ctrl.Name Like "My*" Then
Debug.Print ctrl.Name
End If
Next

What is happening here is that the For-Each statement is calling up the
controls contained in the Controls collection (which VB maintains
automatically for us), one at a time, looking to print out (in the Immediate
window) all those whose name starts with the letters "My".

So, enumureating does not mean making a list, rathers its going through one,
that makes sense!

No, and yes. "To enumerate" is nothing more than "to count". You don't
*make* a list, you just go thru an allready existing one (Like Rick allready
mentioned).

Ofcourse, sometimes that list is somewhat hidden to the programmer's eye,
and/or you enumerate some list to retrieve some specific data outof it
(which you maybe use to store in a user-viewable form).

For example : think about enumerating entries outof a directory (using
"dir(filema sk)" ). The list (directory-entries) is allready there, you just
retrieve them one-by-one, maybe storing (partial) results into a list- or
tree-view.

You're excused. You do *not* want to know the number of questions I did say
"duh !" to when it was explained to me, and thereby the obviousness of it
became clear to me ( the world-famous 20-20 hindsight :-)

Thanks Rudy,

I appreciate your thoughts. You and Rick have helped me through one of my
weaknesses, i.e. at times I tend to make things over-complicated when I
strive to understand them.

Kind Regards,
