Object get type no longer returns the Object Array type in v16r6

Object get type has been changed in 16r something. Probably when collections were introduced in r4 but I wasn’t paying attention. The change is it no longer returns the ‘Object Array’ type (39). Any value that begins with a [ is interpreted as ‘Is collection’ (42). Object arrays still work just

I've updated sideORDA

A few folks have asked me to update sideORDA to include the examples I showed in my 4D Method presentation . I've done that

[TIP] Hiding rows of a collection based listbox (you can't and that's OK)

In prior versions of 4D one of my favorite uses of array based listboxes is for displaying lists of things and including a variable the user could type into to filter the list as they typed. The technique involved two things: the listbox had a 'hidden' array specified the code for the search

MSC: why "Checking list of deleted records ..." persists?

A few months ago a bug resulted in a large number of records being created in a table ([email_que]) by mistake. Bug was fixed and 1 or 2 million bogus records were deleted. Since then the data file has been verified and compacted at least once. Just now I was running a verify on the data file

4D Write Pro license question

Does 4D Server require a 4D Write Pro license for non-UI methods? Let's say I have a database with 10 4D Write Pro licenses. I may have more than 10 users and understand how to check and manage licenses available for users. My question is if I have to 'reserve' a license for the server to be

Re: PDF generation on Windows - Latest Thinking

I agree that PDF Creator is terrible on the server. I tried it briefly and it was a headache. In addition to the points Lutz made doing any printing Server side restricts you to a single print job at a time. That can become a problem - you have to write your own print job que. Plus PDFC can throw

Re: Do I want to use SELECTION TO ARRAY instead of GOTO SELECTED RECORD server-side in V17?

Hey David, You know, you say that RAM is the primary limiting factor but then also say you're only interested in actual timing tests. Umm. Seems like the coding version of the the building contractor talking to a client: You can have it fast You can have it cheap You can have it done well Pick

Re: v17 Orda, Transactions, and ListBoxes with related many

Hi Chris, 1) do table forms have any relevance in ORDA anymore? Sure. Personally I am sticking with them for output forms in user mode, for example. And I'm still including a bare bones input form as well. I wouldn't use it for user-facing production forms. I don’t want to mix ‘classic’ 4D in

Re: PDF generation on Windows - Latest Thinking

Peter, Win10 has a native PDF print engine like MacOS does. You can use it. I don't think PDFCreator 1.7whatever will even run on Win10 (but you probably found that out). On Wed, Sep 12, 2018 at 4:06 AM Peter Jakobsson via 4D_Tech < 4d_tech@lists.4d.com> wrote: > Hi > > For years I used PDF

Re: Securing sensitive data in a 4D data file (Chip Scheide)

I've taken the approach of creating a separate table for storing secure data. Each record has a blob to hold the data. The idea is the sensitive data is encrypted into a blob and the blob is saved in one of these records. The record the data belongs to records the secure record id. When the data

[TIP] Moving elements of a collection

Collections are not arrays. So is I have a collection based listbox and want to have a control to allow the user to move a selected element within the collection how do I do that? One way would be to allow her to drag and drop the element to the new position. The other way is a spinner of some

Re: "Attempting to retype using a pointer"

Jeremy, Since you are writing the data to an object what's the value of using the pointer? Why not just write the data? In fact, since TCMGetRow looks like it is simply holding the data for the transfer you could make it a loop: For($i;1;number of objects) $o["_"+string($i)]:=Object get
