Re: listbox with dynamic filenames "This.timeCreated" how to display time fields

[Christian Sakowski via 4D_Tech]

Hi Ernie,

time columns are supported from 4D v19. As a workaround you can just display 
the time as a String: e. g. String(Time(This.myTime))

Re: entitySelection.add and USE ENTITY SELECTION

[Christian Sakowski via 4D_Tech]

Hi,

i discovered this bug last year. It was registered under:

UID13 - ACI0100101: USE ENTITY SELECTION does not return the correct record in 
selection in C/S-mode if the entity has been added with the method 
'$selection.add'

Answer was:

Problem normally fixed with the Version : 18 build : 243746


Bug Number: ACI0100101

This bug is reproducible with the following 4 versions:

- DEV (243285)
- 18 (243340)
- 17 R6 (243126)
- 17.3 (243342)

ONLY IN CLIENT/SERVER MODE

When creating an entitySelection with newSelection(), USE ENTITY SELECTION does 
not work in C/S-mode. Example:

- Launch the database attached in Client/server mode
-Execute the methode 'P1'

C_OBJECT($selection)
$selection:=ds.T1.newSelection()
$selection.add(ds.T1.get(1))
USE ENTITY SELECTION($selection)

ALERT(String(Records in selection([T1])))

ACTUAL RESULT: 
--> Records in selection([T1]) return 0

EXPECTED RESULT: entitySelection should not change
--> Records in selection([T1]) should return 1

Yes,

just write e. g. „Form.myselection“ in the property-list of the listbox for

Re: maximum number of record

[Christian Sakowski via 4D_Tech]

> a longint value for record numbers - (2^64)-1

The C_LONGINT is 2^32 which is 4 billion. Signed 2 billion.
Starting with v11 (alias 4D 2007), i guess internally the addressable is 128 
bit! Now you can calculate the technical limit of each resource :-)

As i said, the „artificial“ limit is 1.000.000.000:

For Collections and Objects a for-each loop is recommended because it’s easy to

Re: [v17.3] - Clear 4D-Oject

[Christian Sakowski via 4D_Tech]

> I thought that only clears a reference to the object, not the object itself. 

Depends,

if the ref-counter goes to 0, the object itself will be cleared too.

Re: Storage on server suddenly empty

[Christian Sakowski via 4D_Tech]

Hi Jim,

i confirm, we also had this issue with 4D v17R4; never tested R5 (because of 
ORDA-bugs) and now we are testing R6. With R6 we currently have this issue. I 
will let you know if we have this problem again.

Re: How to use collection.query for specific element of embedded collection

[Christian Sakowski via 4D_Tech]

Hi Kirk,

in your example it should work like:

$obj:=New object("id";"some string";"fields";New collection(New 
object("i";0;"name";"value1");New object("i";1;"name";"value2");New 
object("i";1;"name";"value3")))

$selection:=$obj.fields.query("(i == 1) && (name == :1)";"value2")

Re: ORDA and 4D selections

[Christian Sakowski via 4D_Tech]

Chuck and Kirk,

ORDA has many advantages compared to the classic 4D language:
- no side effects,
- no accidentally record locking
- working with (named) relations -> much better readable and very powerful
- much better support and handling of entitySelections (sets)
- now a project method can return an entitySelections in $0 or receive a 
selection as parameter
- display and edit entitySelections directly in a Listbox (without writing any 
line of code!!!)
- display different entitySelections of the same dataClass on a form

just my two zlotychs

Re: ORDA Limiting number of records returned.

[Christian Sakowski via 4D_Tech]

Currently the implementation returns not only a selection, it returns an 
unknown „page“ of records. So there comes maybe hundreds or more records during 
the first query.
The second point is, that when there are object fields in the dataClass, the 
query may be very slow. We discovered a 10-13 seconds delay/latency, when we 
have 1.000 records with 4D Write Pro documents in it.
However, 4D is working on this optimisations. Hopefully.

A small advice:
because 4D sends each dot-statement to the server and back:

ds.Companies.query("…").orderBy(„Name asc")

you can reduce it to just one statement:

ds.Companies.query("… order by Name")

Re: Relation naming for ORDA in v17? Best Practices anyone?

[Christian Sakowski via 4D_Tech]

> I went much simpler…

This is quite the same, but the problem with this approach is, that i cannot 
parse relations generically.

Re: Relation naming for ORDA in v17? Best Practices anyone?

[Christian Sakowski via 4D_Tech]

Yes, since years i use the following:

Given two tables:

[Invoice]
[InvoiceItems]

The id from the invoice is named as:

[InvoiceItems]_Invoice__

(one leading underscore and double underscore as postfix)

For ORDA i name the relation:

[InvoiceItems]_Invoice__MO

(MO means Many to One) which is an entity and

[Invoice]_InvoiceItems__OM

(One to Many) which is an entitySelection

Yes, correct.

When using „use“, all operations are atomic.

Yes, indeed it took some work to rewrite the code to make Plugin-Handles

[ANN] hmReports 6.1 available for 4D v16 and v17

[Christian Sakowski via 4D_Tech]

Today, heubach media released version 6.1 of hmReports.

hmReports is a plug-in developed by heubach media (http://www.hmplugins.com), 
Hamburg, Germany for 4D.

Version 6 is a huge leap for reporting and drawing capabilities in 4D with 
hmReports.

hmReports is fully certified with 4D v16 and 4D v17 and runs with all 32 and 64 
bit versions (Mac+Windows)!

=== New in v6.1 ===
* New PDF tools:
   * hmRep_Create Report With PDF creates a report based on the PDF measures
   * hmRep_Print Over PDF prints a report over a PDF file
   * hmRep_PDF Split splits one PDF into one PDF file per page
   * hmRep_Combine PDF combines two PDF files into one
* The executer and hmReports offscreen areas are thread safe now.
* The parameters of the commands hmX_SET ALLOWED COMMANDS and hmX_GET ALLOWED 
COMMANDS has changed
* New commands hmRep_GET RECT COLUMNS and hmRep_GET RECT ROWS
* New command hmX_Execute to execute a tokenized method
* New command hmX_GET CONTEXT LIST for returning all contexts
* The new command hmRep_Get Current Thread ID returns the current thread ID
* The current tips delay is now supported in hmReports

=== New in v6.0 ===
* Now you can write re-usable code in your reports. You can create 
report-methods and use it everywhere in your reports!
* New rewritten debugger which supports a method stack because of report-methods
* New OPEN/CLOSE PRINTING JOB commands for putting different reports into one 
PDF or printing job
* Change of Object manipulation. $0 can now be any type (also numbers and 
dates). You can set the object's data source to formula to select a data format 
for numbers, dates.
* New text object properties
* SVG output supports styled text now
* and much more (see release notes)

With hmReports we introduced a new dimension of reporting in 4D.
With Multi-Page-Design, Subreports, Barcodes and Editable Preview, hmReports 
offers you long wanted features, which you can directly use TODAY!

=== Multi-Page-Design ===
Now you can add static pages and/or additional iteration pages to a composed 
report. Also, you can design documents with more than one page!

=== Subreports ===
Since Version 3 you can inherit other hmReports documents or pages into new 
documents. For example: You can design one letterhead layout and place it in 
all your reports. If you want to change anything in the header, you only have 
to change the header document and not all of your reports!

=== Barcodes ===
Now you can display any data as a 1D and 2D Barcode without any special fonts. 
hmReports 6 supports over 60 different 1D and 2D Barcode types!

=== Editable Preview===
With hmReports 6, the user can view the final result of the report without 
printing. If data fields and other object don't look good in the preview, you 
can make changes directly in the preview. All changes are automatically saved 
back in the source report and the preview will be updated again, if wanted.

=== Other features of Version 6.0 ===
* Internal PDF rendering engine for creating PDF's on Windows (without 
additional software or printer driver)
* Unlimited Undo/Redo support
* 64 bit Plugin (Mac and Windows)
* Supported languages of the GUI: English, German, French, Spanish, Japanese
* Much better API for guides
* Support of repeating objects
* Variable headers and footers
* Support of Styled Text
* New API for creating a Virtual Structure for Tables, Fields and Variables
* You can now change the name of each section
* New grid
* Arrange objects horizontally and vertically
* Support of line endmarks of line objects
* New Property Palette
* New events for Drag & Drop and printing control
* Direct Copy & Paste from the Finder/Explorer

=== Testimonial ===
Chuck Miller (Informed Solutions, Inc.) about hmReports:

"Your dedication to making products that people can actually use is above and 
beyond. When confronted by a client with a need that makes sense, like 
exporting reports to blob as opposed to text, you take the bull by the horns 
and do it. I can not recommend you or your products any more highly than that."

=== About hmReports ===
You need amazing reports, invoices & documents? Do it with hmReports!
hmReports provides you a powerful tool to create, edit and print powerful 
graphics and reports.

* Create reports without any programming knowledge
* Import SuperReport Pro and 4D Draw documents for a fast crossgrade

Re: Shared Object - NOT!

[Christian Sakowski via 4D_Tech]

Hi Pat,

> But I get an error because $objTriggerState is undefined.

This cannot be true, because you used New shared object.
Please use the debugger and check your code.
I suppose you are using the latest v17 build and you have dot-notation turned 
on.

Re: Scope of entity selection

[Christian Sakowski via 4D_Tech]

> I did not find a way how to do a shared collection from selection, 

You don’t need this. Just pass the object into the process. The object will be 
copied.
If you have performance problems, please let me know your benchmarks.

> creates unordered selection, so order is lost. ds.Table.fromCollection may do 
> that, but at a cost of significant overhead.

Yes indeed.

I create an ordered selection from a collection by doing this:

ARRAY LONGINT($ids;0)
COLLECTION TO ARRAY($collection;$ids)

QUERY WITH ARRAY([table]ID;$ids)
ORDER BY FORMULA([table];Find in array($ids;[table]ID))

Re: Scope of entity selection

[Christian Sakowski via 4D_Tech]

> If not, you could try LONGINT ARRY FROM SELECTION and pack the array into 
> shared object.

Bad idea.

First, you should avoid strongly shared objects in this case.
Second, LONGINT ARRY FROM SELECTION has nothing to do with ORDA.

Third: entities are process depended, because they may use transactions. So you 
cannot pass entities to a new process, because these entities are may be 
invalid.
Fourth: solution: just pass a collection of the ID’s to the new process:

like:
$object.myIDs:=$entitySelection.toCollection("ID“).extract(„ID“)
new process(…;$object)

and in the new process just create the new entity selection:

ds.Table.query(„ID IN :1“;$object.myIDs)

Re: New record numbering system and CALL WORKER

[Christian Sakowski via 4D_Tech]

Tim,

i mainly use Storage as „constants“. I store global attributes and user 
specific options and access rights. Those are in fact mostly read only.

This is not necessary. For just reading you don’t need to use „use“.
For generating sequence numbers, you have to use „auto increment“. Nothing else.
For invoice numbers, you now can save the number to the database within 
transactions with SUSPEND/RESUME TRANSACTION (of course, locking and waiting if 
necessary…)

Re: Adding elements to a listbox containing a collection

[Christian Sakowski via 4D_Tech]

You have to assign the collection to itself:

Form.cColl:=Form.cColl

Then the Listbox will be updated.

Re: collection.min() Returns Null

[Christian Sakowski via 4D_Tech]

Yes, this is expected. You can only do a query() on a Collection with objects.
Where do you get these values? You should select before to get only non-null 
values or remove them from the collection with a For/Each-Loop.

[ANN] hmReports 6.0 available for 4D v16 and v17

[Christian Sakowski via 4D_Tech]

Today, heubach media released version 6.0 of hmReports.

hmReports is a plug-in developed by heubach media (http://www.hmplugins.com), 
Hamburg, Germany for 4D.

Version 6 is a huge leap for reporting and drawing capabilities in 4D with 
hmReports.

hmReports is fully certified with 4D v16 and 4D v17 and runs with all 32 and 64 
bit versions (Mac+Windows)!

=== New in v6.0 ===
* Now you can write re-usable code in your reports. You can create 
report-methods and use it everywhere in your reports!
* New rewritten debugger which supports a method stack because of report-methods
* New OPEN/CLOSE PRINTING JOB commands for putting different reports into one 
PDF or printing job
* Change of Object manipulation. $0 can now be any type (also numbers and 
dates). You can set the object's data source to formula to select a data format 
for numbers, dates.
* New text object properties
* SVG output supports styled text now
* and much more (see release notes)

With hmReports we introduced a new dimension of reporting in 4D.
With Multi-Page-Design, Subreports, Barcodes and Editable Preview, hmReports 
offers you long wanted features, which you can directly use TODAY!

=== Multi-Page-Design ===
Now you can add static pages and/or additional iteration pages to a composed 
report. Also, you can design documents with more than one page!

=== Subreports ===
Since Version 3 you can inherit other hmReports documents or pages into new 
documents. For example: You can design one letterhead layout and place it in 
all your reports. If you want to change anything in the header, you only have 
to change the header document and not all of your reports!

=== Barcodes ===
Now you can display any data as a 1D and 2D Barcode without any special fonts. 
hmReports 6 supports over 60 different 1D and 2D Barcode types!

=== Editable Preview===
With hmReports 6, the user can view the final result of the report without 
printing. If data fields and other object don't look good in the preview, you 
can make changes directly in the preview. All changes are automatically saved 
back in the source report and the preview will be updated again, if wanted.

=== Other features of Version 6.0 ===
* Internal PDF rendering engine for creating PDF's on Windows (without 
additional software or printer driver)
* Unlimited Undo/Redo support
* 64 bit Plugin (Mac and Windows)
* Supported languages of the GUI: English, German, French, Spanish, Japanese
* Much better API for guides
* Support of repeating objects
* Variable headers and footers
* Support of Styled Text
* New API for creating a Virtual Structure for Tables, Fields and Variables
* You can now change the name of each section
* New grid
* Arrange objects horizontally and vertically
* Support of line endmarks of line objects
* New Property Palette
* New events for Drag & Drop and printing control
* Direct Copy & Paste from the Finder/Explorer

=== Testimonial ===
Chuck Miller (Informed Solutions, Inc.) about hmReports:

"Your dedication to making products that people can actually use is above and 
beyond. When confronted by a client with a need that makes sense, like 
exporting reports to blob as opposed to text, you take the bull by the horns 
and do it. I can not recommend you or your products any more highly than that."

=== About hmReports ===
You need amazing reports, invoices & documents? Do it with hmReports!
hmReports provides you a powerful tool to create, edit and print powerful 
graphics and reports.

* Create reports without any programming knowledge
* Import SuperReport Pro and 4D Draw documents for a fast crossgrade
* Exchange and share reports to your customers without recompiling
* Import, edit and export SVG documents
* Open storage format of the report-blob (XML)
* Create vector graphical documents
* Modern graphical API with multiple gradients, alpha/opacity support and 
antialiasing
* Create Text, Rectangles, Lines, Bezier curves, Arcs, Path, Pictures and 
Freehand objects
* Support of stepless zoom
* View and edit multiple reports in one hmReports-area
* Callback routines to manage events
* Break processing with sections
* Support of multiple layers and pages
* Access to the database, arrays, array-elements and variables
* Add scripts to objects and sections
* Support of automatic line height depending of its content. In this case, all 
other objects can be automatically moved or resized.

=== One is not enough ===
hmReports does support multiple detail sections. Now you can create reports 
with real multiple subdetails. For example, you are able to create a report 
with three detail sections (also headers and footers): With hmReports you can 
easily create a customer list with its invoices and for each invoice its 
position.

=== Graphic Editor ===
With hmReports you can create high quality graphics. With the support of layers 
and groups, you can edit complex graphics very easily. Of course you can open, 
edit and save SVG documents as well.

=== hmDraw: hmReports without

Hi,

have you looked at "Selection to JSON" and "JSON TO SELECTION"? But it will not 
cover all field types.

Re: Time stamp with milliseconds

Why not using the command „Timestamp“?
It returns exactly what you need:

[ANN] hmReports 5.2 available for 4D v15 and v16 (32+64 bit)

[Christian Sakowski via 4D_Tech]

Today, heubach media released version 5.2 (Build 28274) of hmReports.

hmReports is a plug-in developed by heubach media (http://www.hmplugins.com), 
Hamburg, Germany for 4th Dimension.

Version 5 is a huge leap for reporting and drawing capabilities in 4D with 
hmReports.

„The main focus for this Version was, to make it rock solid, introducing all 
wishes from Customers, extend existing functions and make it much faster.“ said 
Christian Sakowski, CTO from heubach media.

hmReports is fully certified with 4D v15 and 4D v16 and runs with all 32 and 64 
bit versions (Mac+Windows)!

=== New in v5.2 ===
* New internal script-command _SET ANCHOR to create a table of contents very 
easily. 
* New Undo-commands for creating undo-actions by programming language: 
hmRep_START UNDO RECORDING, hmRep_Validate Undo Recording and hmRep_CANCEL UNDO 
RECORDING

=== In Version 5.0 we made the following improvements ===
* 64 Bit Version for Mac (4D and 4D Server)
* Complete rewritten drawing engine under Windows: Moving from GDI+ to DirectX 
(Direct2D and DirectWrite)
* New commands from copy and paste entire pages: hmRep_GET PAGE and hmRep_SET 
PAGE
* Rewritten intelligent undo/redo functionality:
* New command hmRep_Get Last Event
* Justified alignment is now supported for text objects
* New object properties for setting the visibility of the drag handles
* New command hmRep_Get Section Count
* New section option for page footers: hmRep_svisible_NotOnLastPage
* New options to set the origin of a layer and their objects
* New Undo commands: hmRep_SET UNDO TYPE STATE and hmRep_Get Undo Type State
* New object properties for getting the section of objects in the preview
* New object property to set a custom text for NULL field values
* and much more (see release notes)

With hmReports we introduced a new dimension of reporting in 4D.
With Multi-Page-Design, Subreports, Barcodes and Editable Preview, hmReports 
offers you long wanted features, which you can directly use TODAY!

=== Multi-Page-Design ===
Now you can add static pages and/or additional iteration pages to a composed 
report. Also, you can design documents with more than one page!

=== Subreports ===
Since Version 3 you can inherit other hmReports documents or pages into new 
documents. For example: You can design one letterhead layout and place it in 
all your reports. If you want to change anything in the header, you only have 
to change the header document and not all of your reports!

=== Barcodes ===
Now you can display any data as a 1D and 2D Barcode without any special fonts. 
hmReports 4 supports over 60 different 1D and 2D Barcode types!

=== Editable Preview===
With hmReports 4, the user can view the final result of the report without 
printing. If data fields and other object don't look good in the preview, you 
can make changes directly in the preview. All changes are automatically saved 
back in the source report and the preview will be updated again, if wanted.

=== Other features of Version 5.0 ===
* Internal PDF rendering engine for creating PDF's on Windows (without 
additional software or printer driver)
* Unlimited Undo/Redo support
* 64 bit Plugin (Mac and Windows)
* Supported languages of the GUI: English, German, French, Spanish, Japanese
* Much better API for guides
* Support of repeating objects
* Variable headers and footers
* Support of Styled Text
* New API for creating a Virtual Structure for Tables, Fields and Variables
* You can now change the name of each section
* New grid
* Arrange objects horizontally and vertically
* Support of line endmarks of line objects
* New Property Palette
* New events for Drag & Drop and printing control
* Direct Copy & Paste from the Finder/Explorer

=== Testimonial ===
Chuck Miller (Informed Solutions, Inc.) about hmReports:

"Your dedication to making products that people can actually use is above and 
beyond. When confronted by a client with a need that makes sense, like 
exporting reports to blob as opposed to text, you take the bull by the horns 
and do it. I can not recommend you or your products any more highly than that."

=== About hmReports ===
You need amazing reports, invoices & documents? Do it with hmReports!
hmReports provides you a powerful tool to create, edit and print powerful 
graphics and reports.

* Create reports without any programming knowledge
* Import SuperReport Pro and 4D Draw documents for a fast crossgrade
* Exchange and share reports to your customers without recompiling
* Import, edit and export SVG documents
* Open storage format of the report-blob (XML)
* Create vector graphical documents
* Modern graphical API with multiple gradients, alpha/opacity support and 
antialiasing
* Create Text, Rectangles, Lines, Bezier curves, Arcs, Path, Pictures and 
Freehand objects
* Support of stepless zoom
* View and edit multiple reports in one hmReports-area
* Callback routines to manage events
* Break processing with sections
* Support of multiple layers and pages
* Access to
