List Box preselected row does now work correctly with up/down arrows

[Bill Hernandez-2]

I have been trying to set the initially selected line for a Dialog  
displaying a three column "List Box". Everything appears pretty  
straight forward, and when the dialog is displayed the correct line is  
selected.

The problem I am having is that let's say I pre-select row 5 during the
: (Form Event = On Load) phase, when the dialog displays line 5 is  
selected, BUT when I hit the "down arrow", the selected line jumps to  
line 1, instead of going to line 6.

I have simulated the problem below so that I don't have to post my  
database in order to get someone to look at it to see if they can spot  
the problem.

I found "4D Objects.4dbase" at http://www.4d.com/us/support/resources/exampleapplications.html
and from the File Menu -> 4D Objects Demo, and from the "Direct  
Access" popup menu I selected "List Box".

I went to the :

"Design Menu -> Project Forms -> Objects -> Page (6/22) -> Reset Button"

and added the following code to simulate the problem.


   `---- 4D Objects.4dbase
   `---- Object Method: Objects.Bouton10
   `---- Project Forms : Objects : Page (6/22) : Reset Button

C_LONGINT($i;$no_of_elements)
$no_of_elements:=Size of array(vGridTool)
For ($i;1;$no_of_elements)
        vGridTool{$i}:=False
End for
vGridTool{5}:=True

   `---- NONE OF THESE HELP THE PREVIOUS LINE
   `---- vGridTool:=5
   `---- vArray1:=5
   `---- vArray2:=5
   `---- vArray3:=5

When you run the demo again, and use the "Down Arrow" to scroll  
several lines (Not 5) and hit reset, line 5 is selected correctly, but  
as soon as you hit the down arrow, you get the incorrect line selected.

Any Ideas ?

I have been trying to figure out this for the last couple of days all  
to no avail.

I want to preselect the line base on stored data, and don't want the  
user to have to click on the line in order to get this to work.

Any Ideas ?

I am assuming the you called SCROLL LINES before you called SELECT  
LISTBOX ROW. If not, give that a try.

Phillip,

The above didn't work either...

The title for this email should really be :

SUBJECT : List Box - up/down arrows do not synchronize with pre-
selected List Box row...
REPLACES : List Box preselected row does now work correctly with up/
down arrows

Phillip,

This solved the problem...

SELECT LISTBOX ROW(*;"GridTool";5)

Thanks for pointing me in the right direction...

[Philipp van der Torre]

Since October of last year we have the following problem, and now also  
send this Email to this list, with the hope you can help us:

Problem 1) We send an Email with a problem, and following our Email we  
received a revised database, which did not work either (see point 2):

Case of
        : (Before)
                InInput:=True
                If ([Facturas SUN]Nº Factura=0)
                        [Facturas SUN]Nº Factura:=Sequence number([Facturas SUN])-593
                        [Facturas SUN]Nº Albaran:=Sequence number([Facturas SUN])-630
                        [Facturas SUN]Fecha Factura:=Current date
                        ORDER BY([Line Items]Invoice ID;[Line Items]Item Nº;>)
                End if
        : (During)
                CalcInvoice
End case


1A) Problem: The above method is to give new invoice numbers. Works  
okay with 4d SQL 11.2 mono-user, however, does not work with 4d SQL  
11.2 server/client, due to the following error: when cancelling the  
operation, a new number is added anyway.


   ` bAdd button script
   `
CREATE SET(TheFile->;"Current Selection")
Repeat
        ADD RECORD(TheFile->;*)
        If (OK=1)
                ADD TO SET(TheFile->;"Current Selection")
        End if
Until (OK=0)
USE SET("Current Selection")
CLEAR SET("Current Selection")
SetWindowTitle


2) Here also the revised structure that was sent by 4D was going  
completely wrong as well: when we cancel the operation 4D Client  
simply ignores cancel and adds a numer to the secuence. Then when you  
again want to add a record, for example, an invoice, the secuence  
number is not correct at all! This problem does not exist with 4D  
Professional 11.3, and only with the Server solution!!! We need a  
rapid solution for this all.


Case of
        : (Before)
                InInput:=True
                If ([Facturas SUN]Nº Factura=0)
                        [Facturas SUN]Nº Factura:=Sequence number([Facturas SUN])-595
                        [Facturas SUN]Nº Albaran:=Sequence number([Facturas SUN])-632
                        [Facturas SUN]Fecha Factura:=Current date
                        ORDER BY([Line Items]Invoice ID;[Line Items]Item Nº;>)
                End if
        : (During)
                CalcInvoice
End case


Thanks in advance for your kind help.

Best regards, Philipp
