Hi François,

Does the following "Ask-Reuben" topics answer your questions?

We have  been reading the "Front-end termination" page of the manual (https://4js.com/online_documentation/fjs-fgl-manual-html/#fgl-topics/c_fgl_programs_010.html) so we mostly understand how 4GL generally handles that

Sorry for my typing, I am not used to not being able to correct a post.

When the Google Chrome browser is killed (using the Windows task manager), the 4GL code keeps running (until  some sort of GAS timeout, where the VM gets killed).

Is there a way to get the 4GL pre-notified before the VM gets killed by the GAS?

I meant GBC, not GWC.

When we use:

OPTIONS ON  CLOSE APPLICATION CALL end_app

upon closing the closing of the entire Google Chrome window, Google Chrome closes immediately, but the 4GL code keeps running until the end_app() function completes.

This is mostly good, but is there a way to hold off Google Chrome closing until the 4GL completes?

Also when the tab is closed, could the same holding off be implemented?

Hi,

Targeting Genero 4.01 GWC via GAS.

When writing a simple Hello World GUI with only 1 label ("Hello World"), how can the Google Chrome window.closed / window.closing event ('beforeunload' event) be trapped to tell the 4GL that the web client is closing?

Is there a way to add the following javascript to the web page served by the GAS?

<script type="text/javascript">
window.addEventListener('beforeunload', function (e) {
  // Tell the 4GL program that Google Chrome is closing
});
</script>

If you are trying to import a CSV file with a header using the LOAD command, you can use the IGNORE keyword to skip the first line of the file. Here’s an example:
basket random
LOAD DATA INFILE 'filename.csv'
INTO TABLE tablename
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 ROWS;

The IGNORE 1 ROWS statement tells MySQL to skip the first row of the file, which is the header. This will allow you to import the data from the CSV file without including the header row.

Many thanks for that solution.

Regard,
Clifton Evans

[Next GDC 4.01.07 release - New compatibility plan]

Next GDC 4.01.07 release - New compatibility plan

Dear customers,

Genero Desktop Client (GDC) 4.01.07 will be delivered in the second half of February 2024, and it comes with a new compatibility plan.

GDC 4.01.07 and Genero compatibility:

   GDC 4.01.07 can run in direct mode (SSH) with FGLGWS 4.01 and FGLGWS 3.21.

   GDC 4.01.07 can run on the UA protocol using FGLGWS 4.01 + GAS 4.01 and FGLGWS 3.21 + GAS 3.21.

   When using FGLGWS 3.21 (direct mode or UA protocol), GDC uses native rendering.

   When using FGLGWS 4.01 and above (direct mode or UA protocol), GDC uses universal rendering.

   The Genero Report Viewer (GRV) 5.00, which is included in the GDC, is compatible with FGLGWS 4.00 and FGLGWS 3.21.

 

Warning:

GDC 3.21 will no longer be supported after this release. We will only fix issues in the latest supported GDC version.



What are the advantages for you?
 
1/ You can update progressively to new versions. If one part of your application works with FGLGWS 3.21 and the second part works with FGLGWS 4.01, you can open a single GDC to handle both parts.

2/The GDC will always be working with the latest QT libraries. What does it mean for you?

• The GDC is working with OpenSSL 3
  
• The GDC is working with the latest QtWebEngine to display your web components and Universal Rendering; the latest QtWebEngine uses Chromium as the backend.
  

Compatibility summarized: Look at the attached image.





 

Hello Paul,
 
May I ask you if you get the same problem in Genero BDL 4.01.06 or the latest Genero EAP V5?
 
Thank you,

Hi,

As suggested by Reuben you should check the version you are using, to see if it contains the fix of WCG-145.
Anyway, the best would be to report this problem to your support center with a test case reproducing it.

Regards,
Bernard
