If you haven't already done so, please open a tech support case on taow.4d.com
or file a bug report on forums.4d.fr so that someone investigates this for you.

our list boxes I would expect this to be
slower. In a previous email I mentioned that I do dynamic list boxes
every where I use them.
I always (generic code) append the new column(s).
Listbox Insert column(listbox;size of listbox+1; colname; etc)

That's not surprising, IMHO, it's like concatenation:
hi Alan,
Maybe calling the average was a bit misleading after all :
So I created a demo database with 1 form
On this form I have 12 listboxes with 1 column
On load of each listbox I insert 20 columns with LISTBOX INSERT COLUMN
Inspecting the 4D debug log I am seeing something I did mention
Hi Chip,
When the form is first displayed there are no elements in one of the arrays in
the listboxes
Only after certain user action, like pressing a button, the arrays are
populated, so this isn't the problem
Furthermore, I am not able to test with local 4D data because, surprise, we
don't us

I assumed you built LB with one method per LB.

I assumed that you were "appending" co
24G memory
When showing the listboxes for the first time the arrays have 0 elements (after
on load they are populated via 4D for OCI commands)
Maybe it does matter how many listboxes are on the form?
Maybe LISTBOX INSERT COLUMN becomes slower when more columns are inserted?
Miyako explained clearly
I just tested LISTBOX INSERT COLUMN command on array based LB that takes only 0
to 1 ms to complete on my MBP 2.90GHZ with 16G memory. I'm not sure if size of
array is the factor.

Did your customer try to put up more resources on hardware? Investing 32G+
memory on 4.0Ghz+ machine with great grahic chip for big monitor to run your
application might be helpful especially populating 27 listbox with
thinking aloud, does it make any difference if you insert 400 empty arrays,
and then populate (copy array) the rows,
instead of inserting arrays that already contain data?

Sorry, maybe you are right and I shouldn't have called it poor performance, but
it was my feeling because the command takes 10 times longer to exec
in my view,
I think we need to set reasonable limits on how the commands is expected to be
used,
before we device that its performance is "poor".
is it really reasonable to insert 400 columns in one call?
at what point in developer did you notice the "poor performance"?
did you gradually extend
in all the development and testing when
creating this command nobody ever used it to the high level that you are and
noticed the poor performance.

Hi,
In search of a performance problem in 1 of our forms I am asking for some
advice.
I have succeeded in analyzing 10 4DDebuglog.txt files (using an Oracle DB by
the way) and have come to following :

Yes, you can declare a 2D array of each type and then just allocate listbox
columns as needed from the 2D arrays.

In my case I am flattening out c_objectc/fields. By definition I don’t know how
many keys will be in whatever I’m finding. So I have to pre-declare my best
guess + 10 to have them ready.
I think. There isn’t a way to do this in real time, is there?

Thank you Arnaud, that made me check and I realized that my arrays were local,
not process. Oops.

I forget how v13 may have accomplished this... In v15 the contextual menu has
"Add column before", "Add column after" options. You should also be able to
grab the Header cell of the column and drag it left and right.

If I do that the column is added at the right hand side, then how do I move
it between existing columns 2 & 3.
And how do I delete a column?

Hi
I cant find how to do this.
I have an array based listbox, with several columns.
I now want to add another column between my existing column 2 and column 3
not by code, but in the design environment
Ive tried adding a new column at the right hand end and dragging it, I cant
find an insert column
