Re: [ANN] AJ_MATH 1.2

[GI - AJAR via 4D_Tech]

Hi,

Effectively, there was a trace of a method from the AJ_Tools_UnitTest component 
in the AJ_Math component that makes an unwanted dependency.

This is fixed and you can now download the 1.2.2 version which doesn’t have any 
dependencies.

If you want to look at the unit tests, you must launch the "Math-unit-test” 
project. The "AJ_Math.4dbase" is a component and should not be launched by 
itself, but should be put in the “Components” folder inside another project.

Thanks for the feedback.

Best Regards,

Hi,

We already reported a bug. And yes the way before the fix is to call it twice.

Hi Jeremy,

Thanks for your interest. It is true that I have forgotten to change the color 
of the SQL statements, I rarely use SQL so until today I didn’t face this 
problem. I will update the preferences file on the dropbox.

My 4D Experience Blog

[GI - AJAR via 4D_Tech]

Hi Everyone,

I would like to share with you my blog about my experience with this great 
development tool (for those who didn’t see it yet).

I write my ideas, and experiences I can have within my company AJAR SA as a 
consultant, first level support and 4D developer.

I wish to write more posts but it can be time consuming and time is always 
missing. I have a growing list of stuff I would like to write on it, mainly 
based on trying to explain how 4D work in deep. Let me know if you have any 
ideas on how to improve my blog.

As a small gift for the readers, I have put a small spoil of what coming next 
in the AJ Suite components. I’m sure it will be well appreciated in the 4D 
community.

Here is the link : https://www.my4dexperience.com 


Thanks for your attention.

Re: Dialog (;*) question

[GI - AJAR via 4D_Tech]

Hello Peter,

This is a good question. The actual behavior you are encountering is because 
the process will die after the execution of the code.

Thanks to the worker it is now possible to use a worker to display dialog with 
the * parameter. A worker never die until you kill it with KILL WORKER.

This pattern will allow you to open a new dialog in a worker process called 
“main_windows”.

C_BOOLEAN($1)

If (Count parameters=0)
CALL WORKER("main_windows";Current method name;True)
Else 

$ref_win:=Open form window("myDialog";Plain form window)
DIALOG("myDialog";*)

End if 

Hope it helps.

Best Regards,

Gabriel Inzirillo

Re: $D V17 as a service

[GI -AJAR via 4D_Tech]

Hi Pat. 

We had the same issue some time ago and figured out how to solve the problem. 
The issue was that we use the new architecture for deploymemt and with this new 
architecture, the datafile location is stored in a xml file in the user appdata 
of the user which launch the application the first time. In our case it was the 
Administrator. Because as a Service it was Local System user, 4D stop to run 
because he could not find a datafile to open. The solution was to move this xml 
file in the appdata of the Local System user (located in a deep hidden place 
but findable). This solve our issue.

I dont know if it is the same for you. But I assume you launch 4D as 
Administrator when you launch it normally(not as a service). 

You can also get some more informations in the event logs of windows and get 
the log of why 4D stops. In our case it was written « cannot open a datafile » 
or something like that. 

Hope ut can help.

Re: Delay Worker Process

[GI -AJAR via 4D_Tech]

Hi,

Why do you need to run the check after few seconds?  We use this same kind of 
worker to write logs in files. As you said, the worker assure the file not to 
be opened. So in this contexte you know your file is accessible. You can still 
have an error handler to handle the case where there is an unexpected issue. We 
have a log table for those rare cases. 

I didn't try but a delay process should work in a worker but I would say it is 
not optimal as it will make the stack of the messages to wait seconds before to 
be processed. A worker should be fast so the next messages can be process 
quickly. But it depend on the number of log request you send to the worker.

Re: 4D V16 R6 Vs 4D V16.5

[GI -AJAR via 4D_Tech]

Hi,

For me too it is not confusing. Actually to call it V17 beta is not only more 
confusing but it is wrong. 

Actually you can see v17 as a 16 R7 if you like.

R release make it easier to go through the new features 4D implement by having 
them little by little instead to have a full load of new features after 1 and 
half year. I really think this way of doing is more performant and more nice 
for developers to test things and to give feedback.

I think it improve the quality of 4D.
