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!

Hello Willam, To me, when you enumerate, you make a list of specific items, like
enumerating controls in a form. Am I missing something?
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.

I definitely have a problem to build a clean data structure. I would be

Here is my problem:

-> I would like to link each keyword with a string.
-> I should be able to access the string of a given keyword via that
keyword.

I have a question about enumeration and how to populate them during

I am using vb.net but will happily take any advice in c# as well.
Here is an example to help illustrate what I am after.
Create a class named “clsMyItems” and in that class place an enum.
Public Enum Items
Item1 = 0
Item2 = 1
Item3 = 2

Feedback is appreciated. I'm hoping to provide a "one obvious way" to
do enumerations in Python.

Hi:
How would I bind a list to an enumeration so that enumeration value becomes
list values and enumeration constants becomes list text? Do you loop
through enum and add manually or is there a way to databind like when using
a table as list backing store?

I'm trying to create a simple type that holds two different types. The first is IDREF and the second is an enumeration of string. When I generate a sample xml, I can enter any ID previously stated in the xml and validates correctly. When I try to use one of the enumeration in the drop down list, the xml will not validate.
When I validate the xml in xmlspy, i get the error message "IDREF 'endofprogam': referenced ID 'endofprogam' was not found."...
