Re: Bug or feature?

[Keisuke Miyako via 4D_Tech]

JSON Parse error can be handled with ON ERR CALL, because it is not a runtime 
error.

"Current method name" requires range checking (see docs), but that is unrelated.

you just have to be aware that OK isn't updated,
you can consult "OB Is defined" instead.

Hey Tim,

Thank you for the references. You are always so prompt with spot on links
like that.

I get the thinking about runtime errors - but in the absence of a workable
way to test the validity of a JSON string in compiled mode it seems a good
place for an actual method to do this. Or writing in something in the JSON
Parse methods that throw that error as something that can be trapped. Not
to re hash this discussion but it sure seems like a real problem.

Re(2): "Goodbye 4D Write" email

[Don Lapin via 4D_Tech]

Hi Brian,

You did not answer the question regarding whether 4D will continue to work with 
4D Write (the regular version, not the Pro). That's my primary concern at the 
moment. 

Since my rep told me that it would continue to work at the last developer event 
in San Jose, I don't understand why I would be getting a "Goodbye" email at 
this point. Was he wrong? Did I understand him incorrectly? This product is 
based on the functionality and capability of 4D Write, as painful as it was to 
write those lines of code.

With regard to Pro, last I looked it had a ruler which blocks a much larger 
amount of the writing area (*thick* vertically), making the writing area too 
small on detailed forms. 

The existing 4D Write menus and toolbar use about 2.5 cm on the form, leaving 
about 8.5 cm of useful area (before zoom) for composing. The example you linked 
to, of a 4D Write Pro toolbar and menu combination, is about twice as thick. I 
think I have seen that example before.

How would someone be able to use a word processing area over half of which is 
taken over by those thick elements? 

Fold in:
 
- the apparent absence of the rich command set available in 4D Write, 
particularly commands involving procedural generation of forms and style sheets;
- the absence of control for placing graphics on forms;
- the absence of Word-compatible style sheets;
- the absence of a Word export;

...what is left that's of any utility?

Given how intuitive the existing 4D Write interface is for the average, 
word-processing-type user, why would 4D abandon that? Why do the 4D developers, 
rather than the developers of 4D, need to spend hours trying to reproduce a 
detailed, compact interface that was already in the product?  

Please find some answers if you can. A negative answer to the first one would 
make a product that I have spent most of my time working on since early 2015 
become useless in new versions of 4d. These are all Windows users, so I have no 
interest in 64-bit stuff.


Thank you for responding, 
Don

Re: Bug or feature?

[Kirk Brooks via 4D_Tech]

Has anything moved on this issue?

Just today I was getting runtime errors on the server. You know, the open
dialog, processes hung up. Sigh. It was in a component so i dug into to see
why the error was propagating to the level of stopping things and found
exactly this situation.

Even more, in the midst of looking at things I noticed this quote on the JSON
Parse 
docs:

"This string must be formatted correctly, otherwise a parsing error is
generated. JSON Parse can therefore be used to validate JSON strings."

​And thought: uh - cool. I'll just make a method to test strings more
completely. And ran right into this issue when it's compiled. ​


I hate this sort of stuff.

ImageCaptureCore - to Variable?

[Keith Culotta via 4D_Tech]

Hello,

I'm experimenting with 4d-plugin-ica and it's working.  Is it possible to avoid 
scanning to a disk file?
I tried ICA SET SCAN OPTION ($scanner;Scanner transfer mode;String(Scanner 
transfer mode data))
and can see a BLOB is being built.

Using BLOB TO PICTURE  and BLOB TO VARIABLE (with a picture variable) do not 
result in an image.

Is an image available somewhere using this option?

Thanks,

Keith - CDI

RE: Problems installing built application

[Timothy Penner via 4D_Tech]

> I will experiment with signing BUT I really don't think this is the issue

A quick test to see if your application is in a Translocated (Read-Only) 
quarantine is to run the following code:

ALERT(APPLICATION FILE)

Then check the output.

If the Path is correct and matches where the application is actually installed, 
then you have successfully bypassed GateKeeper.

If the Path is wrong and looks like it begins with a UUID, then your 
application is being Translocated to a Read-Only quarantine due to GateKeeper.

You can do this with the default data file. The new model allows you to startup

on the server, the key.pem file must be near the 4db file. But I don't know 
were to put it if the web server is a client using a "web server for 4d client" 
licence. Wondering about local ressources, near the 4db "clone" but I did not

Re: Problems installing built application

[macjimbo via 4D_Tech]

Thanks for your replies to this. I will experiment with signing BUT I really
don't think this is the issue, for 2 reasons:

1. I've had this problem since before Gatekeeper was invented.
2. I'm familiar with the Gatekeeper dialogs and this isn't one of them.
Gatekeeper would normally prevent the app being opened, but this can be
bypassed by right-clicking the app and selecting 'open'. That's not the
problem here.

This does seem to be some weird permission scenario but I can't get to the
bottom of it. Details of any other successful runtime installations would be
helpful - especially where problems have been found and overcome.

Finally, you are right that the app ought to be a good candidate for using a
default data file, but unfortunately the previous developer built some code
that required the use of the data file as a temporary store for building
certain reports. It's annoying, but I don't have time to unpick all that
stuff! So, for now, the data file will have to stay outside the app.

Thanks!

Array of objects and collection

[Arnaud de Montard via 4D_Tech]

Hi all, 
I have the following piece of code code in a v14R5 DB:

$type:=OB get type($obj;"attrib")
case of
  :($type=is object)  //38
  :($type=is array object) //39
else
  unexpected  //error
end case

It reads a home made json that defines a home made listbox description. 

When upgrading to v16R5, the code goes to unexpected because $type returns Is
