Hi Dave,
Chip's suggestion is what I do with my Uninstall program. You will note
depending on what tree view item is selected I enable the button corresponding
to it. So, my program has everything there you will need. Maybe I lacked in
organization for once I wrote it I did not have time to go back and clean it
up...
So take a good look at the mainproc and how I enable those buttons. Also
download my Uninstall program and get the entire picture on it.

David,
I think your intuition is good here; when you have choices broken into groups
or categories, and especially when the number of these groups might vary so
that you can’t design a static dialog setup for just these groups, then a
treeview (a multi-select treeview in your case) does sound like the best choice.
Perhaps you’ll want to add a command button so that it will read out to the
user a summary of the items which are selected under the current top-level
grouping, if that information makes sense for a user to want in your
application.
Good luck,
Chip
p.s.
I think there are several apps from GW (Aaron) which show the use of
treeviews (one called TreeView, another is UIDesign, and you can still get to
older versions of the appGet app to see their source code, and it used a
TreeView).

Well fact is, that the project is going to have more like 50 entries on the
main level, and up to five sub-level on some of the entries. That is why, I
don't think a load of checkboxes would do. It would not even fit into a screen.
The total list, including all sub-lists, holds more than 300 entries.
And, you are not just to decide Shirt, Pant or Socks. You will also choose
the color, and if available the shade. So, you can choose only pants (with no
color choice), and Shirt with the color green, and for socks, you can choose
both black and Blue. Do you choose blue socks, there is the choices of Skyblue,
Navy or Ocean blue. If you have the chance, please look at the short list I
provided, and pay attention to the levelling of each entry, and you will see
how they are connected with each other.
I could have made a multi-selection list, but then the user will have to
scroll through a ton of colors, for each piece of cloth. All of this, was the
reason, why I thought of a treeview, as it would give the user a quick way of
scrolling down to the cloth he wanted, then expand that one, and check the
colors he wanted.
But apparently I was not explaining this well enough. Thanks anyway for the
ideas. They would have worked in a simpler project, but I have a feeling it
would be hard to have to tab through several hundred checkboxes for putting
together an outfit. :)

Hi David,
Here’s a lazy man’s point of view: why not just have 3 groups of
checkboxes in one dialog; the first group (at the top of the dialog) would be
“shirt”, the second (below the “shirt” group), would be “pants,” and the third
group (below “pants”) would be “socks.” So, all you would need to do is tab
around and check/uncheck to your heart’s content.
Cheers,
Rod

Subject: Suggestion needed, is a Treeview the right thing?
I am about to start out on a new project. But I want to do things the
better way, first go. .)
If I, in short terms, would describe the feature I am trying to figure how
to, let me give this example.
Imagine we have three main levels. Let's for the ease of the example, say
they are:
Shirt
Pant
Socks
. Now imagine, we have subcategories of each, giving different colors, and
maybe even subcategories from there, giving the shades. So, the whole
structure, would look like this:
Shirt
Green
White
Blue
pant
green
red
black
socks
green
light
dark
white
blue
sky
ocean
navy
Black
Yellow.
My first idea, would be to put all of this into a treeview. Thing is, that
I wanted to have the chance of "checking" the different entries. That is, a
person should be able to put a check mark, at the Green, under both Shirt and
Pant. Maybe even check both Green and and white, for the shirt, and green for
the pant.
I have never constructed a treeview, and I don't even know, if it is
possible in a rather simple way - to accomplish what I here am attempting to
do. Hence, my first question would be, is a treeview the right way to go?
Secondly, is it even possible to do what I want? And thirdly, is there any
tutorial, or scripting samples, that would address this kind of task.
Preferably, something that does not contain thousand of lines, in a high-tech
and fancy script.
Ok, I do understand, I would have to deal with dialogs, and treeviews or
whatever, from an XML. Fine enough, but what would be suggested from some of
you more experienced developers out there?
Thanks alot for any feedback,
