Re: v13 - how to manage not enough stack space error

2018-11-15 Thread Ingo Wolf via 4D_Tech
In such cases I use a longint parameter "level" to the recursive method. On 
first run this parameter is set to 1 and is incremented with every level of 
recursion. I then test for an arbitrary "level" (e.g. 1000) and abort the 
further recursion.

Re: Query Editor Date format not available...+

2018-01-11 Thread Ingo Wolf via 4D_Tech
The bug with the numeric format (1) is fixed in a recent v16.

In regard to 2) there is a workaround: in the upper left corner of the query 
editor there's a menu. One of the menu entries is ~ "Reset". Clicking this 
entry resets the query editor, so one can continue to query without closing the 
process or restarting the client.

Re: 4D_Tech Digest, Vol 123, Issue 23

2017-08-14 Thread Ingo Wolf via 4D_Tech
>Like to hear what other alternatives any of you have implemented to make sure 
>4DRemote as Web server is always operational.

I had once a 24/7 online payment system running for a customer. We had three 4D 
Server (all windows), each one (potentially) serving directly the web, with 
attached 4D Clients (all windows) for sending emails, generating PDFs, doing 
payment transactions etc. They were all behind the firewall. In the DMZ there 
was a load balancer together with some apache server (with automatic failover), 
which served static content. All three 4D Server replicated all changes via 
custom programming in near real time. Two of the 4D Server ran without journal 
file and without backup, the last one with journal file and backup. Dynamic 
content was requested from one of the three 4D Servers via reverse proxy. No 
load balancing here, exactly one of the three was the 'active' Server. Which 
one of them was configured in the config files of the apache servers. With this 
setup we could always take one 4D Server down for update or maintenance and 
have the other one active with the third as fail over. The attached clients 
were monitored (and automatically restarted if necessary) by 'robot watchdog' 
from Jens Blomster.

Re: Best solution for printing Enterable PDF docs from 4D v15

2017-06-21 Thread Ingo Wolf via 4D_Tech
Chuck,

we create the PDFs with Adobe Acrobat, not from within 4D. Here's an example of 
an xdp file:







Firmenakte
$PrimaryKey$
  
 $Kundenname$
 $Strasse$
 $Ort$
 $PLZ$
 http://www.xfa.org/schema/xfa-data/1.0/; 
xfa:contentType="image/gif">
  



http://ns.adobe.com/xdp/pdf/;>
   



Table name and primary key are right after . These tags will be 
returned 1:1. All xml tags between  and  correspond to 
form fields in the pdf form (case sensitive). If the same form field has to 
appear multiple times in the pdf form, the corresponding xml tag has to appear 
the same number of times in the xdp (and can have different values!). Use 
CDATA, when the content of the field can have "xml forbidden" characters (e.g. 
"&", "<", ">"). These tags will be returned with whatever content the user has 
entered in the pdf form. You can even fill picture fields (BASE64 encoded).
The pdf file (converted to BASE64) itself has to be placed between  and 
.
In Adobe Lifecycle Designer we add a button to the pdf form with the action 
"send via email". This sends the form fields as xml (xdp, can even include the 
pdf with user modified form fields as BASE64) to a predefined mail address, 
where a 4D process periodically checks the mails and parses the xml attachments 
for updating the records. In Adobe Lifecycle Designer one can also add 
validation code (javascript), e.g. for the email button to be hidden until all 
required fields have been entered.

Sorry, no documentation links at hand, most of this found out by trial

Re: Best solution for printing Enterable PDF docs from 4D v15 or

2017-06-14 Thread Ingo Wolf via 4D_Tech
Hello,

we do exactly what you describe via xdp-files. That are pdf forms encapsulated 
in some xml. The forms are created with Adobe Acrobat and enhanced with 
Livecycle Designer. The pdf is then converted to Base64 and embedded in a xdp, 
wich is xml following some specs from adobe. From 4D we set the values of 
certain xml tags (via PROCESS 4D TAGS), which have the same names as the form 
fields of the pdf form. Adobe Acrobat Reader then feeds these values 
automatically into the corresponding form fields (upon opening the .xdp-file). 
The maybe changed form field values are then sent via email as xml file to 4D 
and imported back into the database records. For linking with the original 
records we have xml tags containig the primary keys.

This is needed and works on both Mac and Windows.

Re: Web Areas On Form Page >1

I did run into this issue, too. At the end of the "On load" form event i set a 
flag and run Set timer. In the "on timer" event i check if the flag is still 
set and if i'm on the page with the web area. If yes, i do WA OPEN URL and 
clear the flag.
My understanding of this is that the web area isn't 'instantiated' until the 
form page containing it is shown for the first time.
