Perfect... Thanks much!
Also, thanks to Chip Scheide for the same advice.
Working perfectly in V17 now!

I have been experimenting with V17 and so far it looks good and solid.
However, there is one issue, new behavior, that has me struggling to figure
out. I have a number of local interpreted databases that generally run in
Custom mode. In those I have a "Quit to User" menu item that has no

in either stand alone, or C/S (on the server)
I have deamons running (process which execute in a repeat until(exit
4D) loop)
There is no reason (see below) based on the code in the deamons, that
these deamons can not be set to run in preemptive mode.

Why not? It isn't supported? I just checked In Transaction in trigger is a
preemptive compliant. It means, preemptive mode does expect transaction. Any
hidden constraint?
Without transaction, trigger is meaningless. When a trigger invoked, mulitple
tables might be updated inside the trigger.
Well, the engine does handle preemptive threads completely transparently since
version 11. We're talking about code that you write for your custom application.

I don't need preemptive client side on data updates. I care about server side
only. Data entry/updates are human works in our case, one at a time (one entry
per second through barcode scanner). If triggers on server could be completed
in less time
even when server loading is heavy, it won't
That sounds really useful!

Hi Rudy,
yes of course I tried all this by myself. With my scenario, in way of working,
in my samples.
But I think that this goes beyond the purpose of this discussion list. I think
discussing possibilities would not help you. I recommend you to contact your
local 4D support subsidiary. And
Is it just me, or does anyone else expect that a database engine would handle
preemptive threads, transactions and concurrence transparently?
Why would I need to know about cooperative versus preemptive threads in the
best of worlds?

Does it make sense for most triggers? Usually you want to know for sure that
code in a trigger has completed before doing anything else in the
table/process, which is kind of the opposite of a preemptive thread.
I suppose for some triggers it would be suitable.

That's what I understand in the first place as following.
- do data entry in a form (UI in application process)
- in the form, I click a button call SAVE RECORD (in the same applicaation
process)
- As long as all codes in the trigger are preemptive compliant, the trigger
would be running in
Achim, have you tried this yourself?
I think it is not possible in 4D Write PRO v17 to select 1 or more cells in a
table and then be able to get the cells reference by code.
Just follow this scenario:
- the user creates a table in 4D Write PRO (by clicking a button containing the

I'm a bit confused.
When I just call SAVE RECORD in data entry form (cooperative process), I was
told it's not OK because it's from a process that have UI. Now, your latest
reply claimed it's OK. Or only if there's no trigger and transaction?
If I create a new process that contain "no" UI from
transactional data entry is kind of task you would typically want to avoid
using preemptive mode.
DB4D requests (19814) are all preemptive since v11,
so if you call the command SAVE RECORD on the client side (a cooperative
process),
the request is still processed on the server side in
Thanks. OK. Forget about the syntax, just the idea.
- open data entry dialog
- check button value
- if button value is validate, save all new value in an object, then call
worker with object and form window process as parameters
- the worker process create new/load an existing record and modify
I tested the KB http://kb.4d.com/assetid=77204, its 4d14 but i forced upgrade
to v16.
The demo has a problem with the video stream, it only shows fragments of the
video from isight.
The capture is as bad as the stream.
Have someone made a 4dv16 version that gives full video quality?

Before you asked for text. I told you how to replace, using WP SET TEXT on a
selection. Now you want to do a different thing, to work on a cell as whole. In
this case you have to select the complete cell and get its reference with WP
Table get cells. This reference on the cell is the parameter
Simply put, preemptive triggers are not for client/server operations even all
