Re: WEB SERVICE CALL parsing error

[Keisuke Miyako via 4D_Tech]

when you process the WSDL (if there is one) using the built-in Wizard of 4D,
you would see orange flags, denoting "complex" types.

http://doc.4d.com/4Dv15/4D/15.4/Subscribing-to-a-Web-Service-in-4D.300-3285567.en.html
Note: If the parsing of the WSDL file reveals the presence of complex type 
parameters, the Wizard displays a yellow flag next to the method concerned

they are complex, in that the values are like objects,
so the parse needs to go more levels deep to reach 4D compatible types (scalar 
or array).

it is not impossible to use such services from 4D,
it's just that the auto-mapping feature of the wizard (and WEB SERVICE CALL) 
are literally out of their depth.

JPR - Content of the World Tour 2017 Training Day

[JPR via 4D_Tech]

[JPR]

Hi Guys,

I've got some demands to described a little bit more what is going to be the 
content of the World Tour 2017's Training day. Some developers would like 
(probably) to know if they will not lose time and money to come and listen to 
JPR's speech once more time...

Most of the topic I will cover are new, as well as the examples I will show. 
This training is entirely based on the new horizons brought by 4D versions from 
V15R5 to V16R2, and how to smoothly make the steps that will lead developers 
using 4D for years, to much more powerful, fast, efficient ways of writing the 
code, thus getting full advantage of this brilliant version. We will boldly go 
together where you have never been before...

So this is a detailed description of what I will teach, explain, and 
demonstrate, during the second day (Training day):

- Adding more Objects in your Code:
Objects in programming
Objects as Parameters
Hashing Functions & Arrays
Associative Arrays

- The Data Structure from Schemaful to Schemaflex:
Objects as Fields
Dealing with variable-structure Fields
Adding User-parametrable Fields to an application in few clicks (with 
Component supplied)
Query, Sort, and use of this fields: Now and tomorrow.
The traps of Key-Value Stores.

- From Static to Dynamic Variables:
Form Object Names.
Form Objects & Data Sources.
Extensive use of ListBoxes.
CallBacks.
Concepts on Contexts. (How to deal with all the different levels of 
contexts)

- From Numbers to Names:
Moving slowly from Table number, Field number, Process number, Record 
number, etc. to Names, why and how.

- From 32-bit to 64-bit:
Reasons why to use 64-bit.
The problems of resources on Mac: PICT, cicn, STR#. (with Component 
supplied)

- From CALL PROCESS to CALL FORM:
Getting rid of the Outside Call event.
Getting rid of the On Timer event.
Getting rid of the CallBack Process.
Multiple windows without multiple processes.

- From Process to Worker:
Similarities & Differences between Process and Worker.
Advantages of Workers.

- From Cooperative to Pre-emptive:
Getting prepared for V16 Multithreading.
Parallel & Asynchronous programming.
Pre-emptive Multithreading: How to get prepared.
Understanding Workers, Processes, and Windows contexts.
Messaging, Slicing, Chunking, without (too much) Head-scratching.
How to go on breathing without Inter-process Variables.

Of course, all the examples I will use during this training will be given on 
the USB key. I spend a lot of time to find the easiest and lowest energy path, 
and I think, honestly, that the time you will spend in this one-day training 
will not be lost, for it will save you a lot on trying to break new ground in 
development. I'm 101% sure that the development time you will save worth the 
time you will spend coming to this day. And also the money. And even much 
more...

And if, after the training, you think you have lost your time and money, I 
promise I will make amends and cut a little finger (or a 3D printing of it, 
let's be modern!)

I hope to see you during this Tour, I got so many good memories of the 2015 
Tour! And meanwhile, should you have any questions, please feel free to ask it!

My very best,

JPR

P.S. You didn't ask about the first day, so I will not describe what you will 
see, but be sure it will not only be a lot of very interesting things in the 
topic "Yes you can do this with 4D V16", but it will be also a lot of fun!

WEB SERVICE CALL parsing error

[John Baughman via 4D_Tech]

I am getting the following error…

Error when executing the method "proxy_GetAllProjects" at line number 44

-
Error 9911 (The returned XML is incorrect. : Complex types are not parsed in 
this version.
error at line 1238, column 0: invalid character reference

What does "Complex types are not parsed in this version” mean? 
I have sent a message to the web service to make sure the problem is not on 
their end, but Is there anything I can do on my end to get the response? As it 
is an empty blob is received.

Re: RESOURCE LIST & XLIFF Resource Files

Miyako, rather than creating an array of the strings within a designated list, 
I want to create arrays of the string list ids and resnames analogous to the 
results of "RESOURCE LIST (“STR#”; ResIDs_an;ResNames_at)".  My existing DBs 
rely on these arrays to reference the strings within each list.

Nigel, with a bit of tinkering and lots of testing in the debugger I have 
gotten a variant of the code you posted to work.  In its raw state it is 
already adequate for my immediate purposes, with converted DBs.  But I intend 
to tweak it a bit more so that it can locate the Resource folder in 4dbase 
packages as well.  Mañana.  When it has a bit more polish I will post my code, 
just in case it may be of some use to others.  

Thanks again to both of you.

osx open url vs osascript FYI

[David Ringsmuth via 4D_Tech]

4D v15.2
OSX 10.12+

I tried many different things to launch a .htm on OSX using OPEN URL, and it 
would not automatically open the document.

Included “safari” in the OPEN URL.
Used the “*” parameter in OPEN URL.
Stripped the volume name.
Removed Document Type and Creator, replaced with 4*char(0).
Added the Type in CREATE DOCUMENT.

So I used:

$outputStream_t:=""
$errorStream_t:=""

$LF:=Char(Line feed)

$script_t:="tell application \"Finder\""+$LF
$script_t:=$script_t+"print \""+$Path_Doc_t+"\" as alias"+$LF
$script_t:=$script_t+"end tell"+$LF
LAUNCH EXTERNAL PROCESS("osascript -";$script_t;$outputStream_t;$errorStream_t)

This works great!

Since v11 I use "auto increment": never. 

About index kind, unique _must_ be b-tree. 
Distinct value gives as much items as records? 
Some NaN (not a number) in the values?

Re: 4D v15.4: Sequence number issue / Duplicate key error

[Kirk Brooks via 4D_Tech]

Rudy,
I still use longint IDs as PKs on a lot of tables in v15 with no problems.
All of them autoincrement however. Like I said before if I need to ensure a
sequence I don't use the PK.

RE: 4D 15.4 HF1 (windows) - crashes when run as service

[Timothy Penner via 4D_Tech]

Hi Keith,

> Is this meant as a reminder to 4D to not create a user interface for 4D 
> Server?  ;-)   (4D may be working towards a headless 4D Server?)

That was meant as a reminder for the 4D Community to not activate the user 
interface on service. Here is another reminder:
When 4D Server is launched as a service the 4D Server Administration is not 
displayed; one must interact with the service and choose to display the Admin 
Window from 4D's Window Menu. Interacting with the service is already 
discouraged on the latest versions of Windows and one must modify the registry 
to even see the service. In addition, we have discouraged creating interfaces 
on the server for many versions/years (see forbidden and inappropriate commands 
here: http://livedoc.4d.com/4Dv15.4/help/Title/en/page2759.html and a similar 
list for v11: http://livedoc.4d.com/4D-Serverv11.6/help/Title/en/page316.html)

Yes, using the Administration Window on the 4D Remote (client) is the perfect 
solution for this. As to your catch 22 the best answer is to purchase enough 
license for your users, and then the 2 included licenses from 4D Server could 
be used for Administrator and/or Designer related tasks. Neil and Tom have also 
provided very good responses for this.

> Good to know that this has been fixed, so thanks.

The fixed versions are already available in the Nightly Build forums.

I hope this helps,

Hmmm. I am using
v16HF2 -  64bit

It instantly crashes as soon as I select the "Canvas Plugin Area" plugin
type.

I'll try with the 32-bit version and see if that behaves better.

When 4D Server starts up, have it launch a 4D Client logged into 4D Server. 
That way it will always get the first license and you'll have access to the 
Administration Window.

4D v15.4: Internet commands

[Two Way Communications via 4D_Tech]

Hi guys,

Since my customer is using 4D v15.4 (2 weeks now), he is experiencing frequent 
issues while sending e-mails.

I did have to change SMTP_SetPrefs from (0;1;0) to (1;8;0), but 95% of the 
emails are sent correctly.

For the other 5%, they get an error mail from the provider’s email stating that 
the e-mail could not be delivered.

it says:

Status: 5.1.1
Diagnostic-Code: smtp; 501 5.5.4 Syntax error in BODY parameter


Has 4D something changed in the headers of outgoing mail messages? What is it 
doing different in v15.4?

Re: 4D v15.4: Sequence number issue / Duplicate key error

[Two Way Communications via 4D_Tech]

Hi Arnaud,

Yes, it is only 4D v15.4 (haven’t tried yet with v15R4)

Index kind: I tried all, no difference

It is a small table (20.000 records)

Rebuilding the index fixes the problem for a short while, but it returns. 
Database has been compacted twice, no errors.

I wonder … has anybody else had issues with Primary keys in combination with 
sequence number?

Buy licenses for each user, you get 2 for free with a purchase of a 4D server, 
you can use these as spares :)

Re: RESOURCE LIST & XLIFF Resource Files

[Nigel Greenlee via 4D_Tech]

Steven

I don’t have an exact solution for you. but the following might give you some 
pointers on the way to go. I got this code from the 4DBB-I DID NOT WRITE IT 
MYSELF. it extracts all the 4D constants from the constants xliff file.

C_POINTER($1;$constantNames_p_at)
C_POINTER($2;$constantIDs_p_at)

C_TIME($constantsXLIFFFile_h)
C_TEXT($constantsXLIFFFile_t)
C_TEXT($elementName_t;$elementPrefix_t;$constantName_t;$constantID_t)
C_BOOLEAN($transUnitFound_f;$targetFound_f)
C_LONGINT($SAXEvent_l;$pos_l)

ARRAY TEXT($attributeNames_at;0)
ARRAY TEXT($attributeVals_at;0)

$constantNames_p_at:=$1
$constantIDs_p_at:=$2

$constantsXLIFFFile_t:=(Application file)+Folder separator+"Contents"+Folder 
separator+"Resources"+Folder separator+"en.lproj"+Folder 
separator+"4D_ConstantsEN.xlf"

$constantsXLIFFFile_h:=Open document($constantsXLIFFFile_t;Read mode)

If (OK=1)

Repeat 
$SAXEvent_l:=SAX Get XML node($constantsXLIFFFile_h)
Case of 

: ($SAXEvent_l=XML start element)
SAX GET XML ELEMENT($constantsXLIFFFile_h;$elementName_t;\
$elementPrefix_t;$attributeNames_at;$attributeVals_at)

  // Need to locate the "target" element for each constant "trans-unit".
Case of 
: ($elementName_t="trans-unit")
$pos_l:=Find in array($attributeNames_at;"id")
If ($pos_l>0)
$constantID_t:=$attributeVals_at{$pos_l}
  // Ignore the first trans-unit in each group, it's not a constant.
If ($constantID_t#"@_0")
$transUnitFound_f:=True
$constantID_t:=Substring($constantID_t;3)
Else 

End if 
End if 

: ($elementName_t="target")
If ($transUnitFound_f)
$targetFound_f:=True
$transUnitFound_f:=False
End if 
End case 

: ($SAXEvent_l=XML DATA)
  // With the target located, we have the constant name.
If ($targetFound_f)
SAX GET XML ELEMENT VALUE($constantsXLIFFFile_h;$constantName_t)
APPEND TO ARRAY($constantNames_p_at->;$constantName_t)
APPEND TO ARRAY($constantIDs_p_at->;Num($constantID_t))
$constantName_t:=""
$constantID_t:=""
$targetFound_f:=False
End if 

End case 
Until ($SAXEvent_l=XML end document)

CLOSE DOCUMENT($constantsXLIFFFile_h)
End if

RE: 4D 15.4 HF1 (windows) - crashes when run as service

[Keith White via 4D_Tech]

>Reminder: it is not recommended to create user interface on 4D Server when 
>launched as a service

Tim

Is this meant as a reminder to 4D to not create a user interface for 4D Server? 
 ;-)   (4D may be working towards a headless 4D Server?)

Retaining access to 4D Server's user interface is currently essential for 
system admins to be able to drop users or to see 4D error message dialogs that 
may have appeared on the 4D Server UI.

Good to know that this has been fixed, so thanks.

Now I know you're going to tell me that you can use the 4D Remote 
Administration Window to do the drop-users thing.  Great, but how do you get to 
_that_ if all your 4D connection licenses are currently used up?  Catch-22

Best regards
