Re: WAN vs LAN Cache

[Jeffrey Kain via 4D_Tech]

In v17R5 that number changes if you use different instances of 4D.  As long as 
you use the same copy of the 4D application then it uses the same cache folder.

Is this on Mac or Windows, and where is your 4D application installed?

Re: Long running reports

[Jeffrey Kain via 4D_Tech]

Hey John - 

If it's on a Windows server, check out Process Monitor (procmon). It runs in 
the background and gives you a log of every filesystem activity. It's pretty 
amazing the stuff it reveals... but it should be able to track down who/when 
deleted your file:

Re: Drop User NOT working (after client disconnected using Force Quit)

This is what I do as well.  Drop User doesn't work at all in v17R5, but killing

The issue of ghost users sounds like our experience when we tried the 
not-so-new network layer. We don't see it very often at all with the legacy

You can specify a larger maximum but it doesn't work.

Also, the documentation also says 32000 is the maximum size of a text variable, 
which is wrong.

Overreact much?  Yesterday I needed 32023 bytes.  Fixed it, moved on, posted a 
light-hearted comment to this thread that maybe something got overlooked.

Re: NTK 32K limit in TCP Receive

[Jeffrey Kain via 4D_Tech]

Two problems;

First, the maximum size of a text variable isn't 32000 bytes anymore, which 
leads me to believe this was an oversight and not a feature... :)

Second, it was easy to receive text until a stop character is received, as long 
as the data is less than 32K.  When your packets become larger than 32K it 
becomes more complicated.  In my use case it was easy since we'll only ever 
receive one 'packet' per connection, but the code grows more complicated if you 
need to support an arbitrary number.

What's the problem with removing the arbitrary 32K limit?

Nope, it's for real.

Re: 4D Application as a 3-tier System

[Jeffrey Kain via 4D_Tech]

I don't manage them, but we use A10 load balancers for our 4 4D Client 
instances running as virtual machines that serve web service requests from our 
website and a variety of other non-4D applications. The 4D Clients are running 
an HTTP server based on NTK (very very similar to the sample HTTP server 
provided with NTK). It's pretty easy to add and remove clients if we need to 
beef up the number of 4D Client instances for a big event, or scale back if a 
VM goes offline or whatever

https://www.a10networks.com/products/thunder-adc/

I remember at Orchard that some of our more advanced customers also installed 
load balancers in front of 4D Client-based 4D web servers, pretty much on their 
own.  Your 4D code has no idea that there's a load balancer running, so you 
don't have to write anything special for it.

HTH (better) :)

Re: MySQL connection from 4D

[Jeffrey Kain via 4D_Tech]

If you don't get anywhere with SQL LOGIN (which should work, given the right 
driver settings), Pluggers Software sells the MyConnect plug-in which works 
perfectly and is very fast/reliable.

https://www.pluggers.nl/product/myconnect-plugin/

We've been using it for many years performing crucial functions interfacing 4D 
with our web stack that run 24x7x365.

Re: Capturing barcodes without a 'text' field

[Jeffrey Kain via 4D_Tech]

If you want to use a USB barcode scanner and still have complete control, you 
can use ON EVENT CALL to manage this. You'll need to program a prefix character 
and a suffix character into the barcode scanner, and have your ON EVENT CALL 
method watch for these characters to determine what to do.

For example, if you scan the text 123, and your barcode prefix character is 
 and the suffix character is , the stream passed to 4D will look like 
this:

123

So - for those forms where you want to process a barcode, you install an ON 
EVENT CALL method that's waiting for an  keypress event. When it sees one, 
it starts collecting the subsequent characters into a text variable (and 
filtering them from the event stream that would otherwise pass those characters 
to the form) until it sees an .

When it sees an , it stops collecting characters and then passes the 
buffer of what it collected back to the form (CALL FORM or CALL PROCESS if 
you're on an older version of 4D).

It's a fair amount of code and it takes awhile to shake out all the bugs, but 
it gives you complete control over the barcode scanner.

Re: QUERY WITH ARRAY - SQL Equivalent?

[Jeffrey Kain via 4D_Tech]

SELECT ... FROM Table WHERE [ID] in ( comma separated list of IDs )

ID is a reserved word in sql so if that’s the name of your field you need to 
escape it (I use brackets in 4D).

Re: Object property inheritance - why does this this not work ?

[Jeffrey Kain via 4D_Tech]

I think you should stop thinking about dot notation as object orientation. 
Concepts like classes and inheritance aren't supported yet, and saying 
$animal:=$dog isn't inheritance -- it's just assigning one object's reference 
to another and kind of backwards at that.

Don't try to fit a square peg into a round hole just yet. 4D has said these 
things are coming.

4D had a weird example in their blog, though... you could make a method called 
"New Animal" (yes, with a space... cheap trick), that creates an object and 
sets some properties for all animals. Then you could write

$dog:=New Animal

... and then start customizing the properties of dog based on the 
not-really-a-superclass Animal. 

I think this is a waste of time knowing that a proper implementation is coming 
someday... and having a space in the method name is bad enough, but there's no 
proper support for this in the language, debugger, or compiler yet, and you'll 
probably end up rewriting it all someday relatively soon anyway.

Re: Overlapping Objects in Data Segment #65

[Jeffrey Kain via 4D_Tech]

It seemed to be a problem with the address table. I had to end task while 
indexing during an R5 upgrade of one of our mirrors due to the cache memory 
release issue in current versions, and address table errors during journal file 
integrations appeared shortly after bringing the mirror back online in R5.

I restored that data file back to the 17.1 version and verified it and it came 
back with a completely clean bill of health.  I'll try the R5 reindex once 
again after I figure out how to get it to complete without locking up when the 
cache memory (~ 400GB) is full.  

I'm thinking I'll set the cache very high (higher than physical memory) and let 
Windows handle the memory overflow, so 4D never has to release cache memory. Or 
buy more RAM.

Jeff

P.S. - I think issues in the .4DIndy are always indicated by a reference to the 
table "Resources".

Re: can't load internal 4D component

We had similar errors on Mac due to our anti-malware package which actually

Re: 4D v17r4 Windows Print To PDF ignoring PAGE SETUP

[Jeffrey Kain via 4D_Tech]

Paper names also differ across different drivers on the same platform.  In 
64-bit Mac 4D, SET PRINT OPTION fails with an OK of 0 if you specify a paper 
name that doesn't exist on your current printer, so you either need to get an 
array of all the available paper types and write some code to figure out what 
you want, or specify height and width in pixels.

Re: 4D v17r4 Windows Print To PDF ignoring PAGE SETUP

[Jeffrey Kain via 4D_Tech]

On 64-bit Mac, if you specify a paper size that does not exist in your driver, 
OK gets set to zero and your job won’t print. This is new behavior.  Best to 
set pixels for page width and height.  Even different drivers on Macs have 
different names for paper sizes.

Re: 4D v17r4 Windows Print To PDF ignoring PAGE SETUP

[Jeffrey Kain via 4D_Tech]

When we upgraded to v17 64-bit, the biggest thing we had to change were old 
printing forms.  To get them to work, I changed old reports that relied on 
saved page setups to use the equivalent SET PRINT OPTION command, and it worked 
in all cases...

Re: 4D v17r4 Windows Print To PDF ignoring PAGE SETUP

The newest versions of 4D do better if you set these options in code instead of 
a saved page setup.  Try using SET PRINT OPTION to change it to landscape mode.

Re: Macs slow down generating PDFs

[Jeffrey Kain via 4D_Tech]

Interesting - Mac 32-bit is blazing fast and doesn't have this issue.  64-bit 
Mac can crank about a one per second (slowing down to a handful per minute 
after a few hours). Windows 10 is steady at about 1 per second on very fast 
hardware.  My 2017 iMac running v17 32-bit can rip through about 3 per second 
and it doesn't slow down.

Macs slow down generating PDFs

[Jeffrey Kain via 4D_Tech]

Anyone notice that generating a large batch of PDFs on MacOS slows down? I'm 
trying to generate several thousand PDFs, and it starts out (on my Mac) at a 
clip of over 1 per second... after an hour it's down one every few seconds... 
after a few hours its a couple of PDFs per minute.

Same code on Windows doesn't have this gradual slowdown.

Username/password dialog timeout in v17

[Jeffrey Kain via 4D_Tech]

Does anyone know if the timeout that 4D Server will allow 4D Remote to stay at 
the username/password dialog can be adjusted?

I don't remember a timeout in previous versions, but it appears that there is 
one now. If you leave it for too long and then sign in, you get a "The 
connection to the database has been interrupted" message.

This is 4D Server 17.1 HF2 and 4D Remote 17.1.


Thanks...

Re: Window type -724 (more info)

You should look at the v17 docs for the window types that will work going 
forward.  A lot of these old window types won’t work on 64-bit - it won’t crash 
but some odd things happen like opening the new form in the existing window, 
etc. 

Stick to the v17 documented window types for best results going forward

Re: Konstants - trying to determine where it is defined

[Jeffrey Kain via 4D_Tech]

Is a Konstant a Russian version of a constant? :)

Constants are normally defined in an xliff file in Resources (for a 4D 
structure), or inside the bundle of a plug-in or component (probably also in 
Resources).  For example, our application's constants file is named 
Constants_Sweetwater.xlf and sits in the Resources folder next to the .4DC file.

Re: Benefits of 64-bit 4D Remote

[Jeffrey Kain via 4D_Tech]

There's really no compelling reason if you're still on v16.  32-bit works fine. 
 As Arnaud wrote things may be changing in the Fall with the next release of 
macOS. My guess is that some kind of virtualization will be required to run 
32-bit stuff at that point.

Also, the 64-bit version of 4D v17 is a lot better than v16.

Re: SET PRINT OPTION Fails on a New Macbook Air

[Jeffrey Kain via 4D_Tech]

Not sure if you're on 32-bit or 64-bit, but printing on 64-bit is fussier -- it 
wants to have paper sizes assigned with SET PRINT OPTION that match exactly the 
printer you're printing to, otherwise it sets OK to zero and it won't print.  
The workaround I found, since different drivers have wildly different paper 
sizes, is to use the variation of the command that specifies a print area in 
pixels instead of a named paper size.

 Running 4D Server under Windows Server is pretty straightforward. I don’t 
 know about specific WS 2016 issues, but in general there are only a few 
 things to set for 4D Server to run best. 
 
 One thing to make sure is to set it to be optimized as a data server, not 
 a file server. In WS 2008 that setting was in the “Performance Options” 
 control Panel, but may be elsewhere in v2016.

One point - in Windows Server 2016, Windows Defender is turned on by default

Re: I really recommend the 4D World Tour

[Jeffrey Kain via 4D_Tech]

I agree - it's easy to cherry-pick examples that are well-suited to ORDA.  The 
ORDA engine is definitely fast, but our tests show that the classic commands 
are still faster overall.  You just have to write a lot more code.

In my tests in client/server mode (and 4D always demos ORDA in single-user 
mode), ORDA is usually about 10x faster than equivalent SQL, but still several 
times slower than classic (and OMG 10x faster! .. but we're talking 
milliseconds usually). If all you care about is raw speed, then classic 4D is 
probably still the fastest... but ORDA is very elegant, and it makes 
development easier and fun.

If you get into tokenization vs. strings, then the picture gets muddier... but 
once 4D gives us the option to have a text file-based structure then a whole 
new world of tools open up for maintaining and refactoring code (with a steep 
learning code). Times are changing. 4D is joining the rest of the programming 
language world (and not forcing us to rewrite).

Re: LEP - hide console?

[Jeffrey Kain via 4D_Tech]

Hi Pat,

Did you try calling SET ENVIRONMENT VARIABLE with the _4D_OPTION_HIDE_CONSOLE 
option?  It works with normal batch windows... not sure about PowerShell 
windows.

PDF viewing alternative in v17/64 bit

[Jeffrey Kain via 4D_Tech]

Just ran into a nice surprise in 4D v17 on 64-bit using the embedded "Blink" 
web area... it has a very nice cross-platform PDF viewer built in. Just pass 
the path of a PDF into WA Open URL and it will display exactly the same on both 
Mac and Windows -- no plug-ins or extra configuration required.

That's the point of workers.

You queue up messages for the worker to handle, in order, so your calling

4D Server v17.1 and time change

[Jeffrey Kain via 4D_Tech]

Did anyone else have any weirdness with their 4D Server v17.1 and the change to 
Daylight Savings Time this morning?

Most, but not all, of our users got disconnected around the time of the change, 
the SQL server and the 4D Server UDP port that broadcasts the server name 
stopped responding (we have Nagios checks on both of these and they both 
started alerting), and when we went to quit 4D Server it just quit immediately 
without giving the usual chance for a countdown.

Could be a fluke I guess? But it seems awfully suspicious that it happened 
right around the time change, so I'm just curious if anyone else saw anything 
weird?

Re: Closing a window with another application in focus

Kirk/Albert Brooks pointed me in the right direction -- if you open the window 
with Open Form Window, then the behavior is just automatic. If you open the

write a handler for that event.  

64-bit seems pickier/more consistent than 32-bit.

Closing a window with another application in focus

[Jeffrey Kain via 4D_Tech]

On macOS - some of the windows in my application will close if I click on the 
close box while another application has the focus, but others don't.

Does anyone know what the secret is for this? They all close fine if 4D is the 
frontmost application - even if other 4D windows are on top I can close 
non-focused window with a single click to the close box.

Re: Does 4D 64-bit Volume desktop use more than 1 core?

[Jeffrey Kain via 4D_Tech]

No, not at all. You have to first mark the method that's called first from New 
Process as preemptive. That method, plus all methods called by that method, and 
all methods called by those methods, must be written in a preemptive-safe 
manner (i.e. no UI, no unsafe commands, no plug-ins).

If all that happens, that process will be scalable across cores.

Re: Does 4D 64-bit Volume desktop use more than 1 core?

[Jeffrey Kain via 4D_Tech]

Compiled 64-bit Volume Desktop can use more than one core, depending upon how 
you write your code. 64-bit 4D is required, as is being compiled, in the 
current implementation.  

You need to write preemptive-safe methods and your methods need to be marked as 
preemptive in the method properties.

Re: 4D Server V17.0 crashing on database open

[Jeffrey Kain via 4D_Tech]

Have you tried rebooting the server? Once in awhile our server will get into a 
pattern like this and the only solution is a reboot. I believe, but haven't 
proven yet, that it has something to do with 4D Server not closing all of its 
ports correctly when you shut down.
