RE: Collections Issue

Doug,

Collections all have a “.length”, read only function.

For($i;$Col.length-1;0;-1)
$Col[$i]…

results in alerts for “Curly” and “Moe”. That’s expected because the docs
state “end is excluded”.




*For each* ($name_T;$coll_C;2;0)


*ALERT*($name_T)


*End for each*


results in no alerts. That’s not expected.


How does one iterate backwards through a collection? I realize that I can
reverse the collection and iterate forward through it but there’s
no contraindication to iterating backward.

OSX Catalina, 4Dv17R6 built application, path to datafile not remembering

[David Ringsmuth via 4D_Tech]

We installed our compiled, built 4D v17R6 app on OSX Catalina.

Each time we launch the app, it presents a UI request for the path to the data 
file.

We made the app folder Read Write for all.

It seems this is a Catalina issue.

I need ideas so our users don’t have to find the datafile every launch of the 
application.

Thanks!

RE: Making a package of a built Mac volume desktop

[David Ringsmuth via 4D_Tech]

John,

Apparently, there is some bug, in some OS’s, that importing the Apple Developer 
Cert with KeyChain, it is not recognized. Even with a fresh OS certificate 
import. DropDMG also fails to recognize it.

I don’t know the solution yet….

I wish it was always easy!

> What do you want the package to do when you double-click it?
Good question. When I double-click the the app I would like it to launch with 
the data file. 

I created a folder “Data” and put the various 4D data files in it. Then I put 
the “Data” folder into the My4D.app. The first time it is launched it asks me 
to open a data file. I navigate to and select the data file inside of My4D.app. 
The second time it is launched it remembers where the data file was. So this is 
a good solution to have everything in one .app package. 

But sometimes there will be updates and the old data should be used. The 
everything in one package becomes problematic because it is too hard for the 
user to deal with the data files. It may be better to have the Data folder 
outside of the .app to make it easier for my users to swap in new code. It 
might be tougher for them to locate the old data file.

One other thing. I notice that there is a _CodeSignature file in the app. I 
think the app gets signed in the build interface. Does adding a data folder to 
the app affect the code signing? 

Also I signed up to become an Apple Developer. It took me a couple of days to 
read/skim the 80 page agreement. Now I have to figure out what to do to get 
code signing approval. I think they call it a ticket.

PRINTERS LIST

[David Ringsmuth via 4D_Tech]

Apparently 4D loads it’s copy of current available printers at launch.

Obviously there are times when available printers change during a 4D user login 
session.

There should be an option in the PRINTERS LIST command that causes 4D to 
refresh it’s copy of the available printers.

Should this be a feature request?

RE: Picture Reduction / Conversion (2)

Narinder,

Re: “did you try to re-saving the source PNG image using an external program”

Yes, resaving the PNG using Paint.net made the PNG convert-able to JPG.

I’m guessing the original PNG is a camera photo, and non-standard in some way.

David,

Hmm... tricky one to try and troubleshoot over the list. Picking up on your 
point about trying with Paint.net, did you try to re-saving the source PNG 
image using an external program, also tweaking the compression or other 
parameters of the PNG (assuming that is possible...) and then trying to CREATE 
THUMBNAIL from that? It might help you to narrow down whether the issue is 
internal compression or not?

On a couple of computers an application using NTK 3.1.0 is crashing while 
accessing:

https://maps.googleapis.com/maps/api/geocode/xml?address=

Most of the other computers can access this URL without any problem.

We disabled the firewall and the anti-virus.
We deleted the local application cache.
We installed a fresh 4D v17R4 232574.
We restarted the computer.

It still crashed when NTK 3.1.0 is used to contact googleapis.com.

My next step is to replace the NTK call with 4D’s own HTTP Get.

Suggestions please!

Compiler Speed slow-down after testing Can be run in pre-emptive process

I set one of my processes to “Can be run in pre-emptive process”, just to see

There were so many issues that I set the method back to “indifferent”. I also 
toggled it with “Cannot be run in a pre-emptive process.”

Ever since then, my compiles are running about 2 times slower for this 
application.

I am wondering if these two things are related?

RE: can't load internal 4D component

Lutz,

The six components not loaded were internal to 4D. 4D would not launch because 
of the 2019 compatibility mode not enabled. It never got to “running”, where it 
would be able to open an 4D structure.

Yes, I tested the nightly build of v17R5.239769, and it would NOT run 4D on

Hi David,

a question regarding this compatibility mode: Did you try it with 4D v17R5 too? 
In your first posting you only mentioned v17R4. The Software requirements 
document 
(https://download.4d.com/Documents/Products_Documentation/LastVersions/Line_17R5/VIntl/4D_v17_R5_SystemRequirements_EN.pdf)
 by 4D states 4D v17R5 is supported by Windows Server Systems in the range of 
Windows Server 2012 – Windows Server 2019.
It would be at least disappointing if it we have to switch such a compatibility 
setting on. This means more or less 4D is even not compatible with Windows 
server 2019.

Or is your component the cause of the trouble?

We had similar errors on Mac due to our anti-malware package which actually 
removed contents of the 4D bundle that it thought were unsafe.  Have you

can't load internal 4D component

[David Ringsmuth via 4D_Tech]

4Dv17R4 build 233874
Windows Server 2019 1809 build 17763.397 (64bit)

An installed 4Dv17R4 application began not correctly launching this morning on 
the  error(s).

650 (xbox) Folder (name) not found (path) xtoolbox task 1444
Cannot open the structure of the database development
Can’t load component development.4DC component ‘4DRT’ task 1444

This error occurs for every c:\Program Files\4D\Resources\Internal Components\  
of which there are six internal components.

I re-installed the 4Dv17R4 application and the newly installed app has the same 
error.

I’m suspicious of the OS.

4D Server is running on this same machine and it uses four of the same internal 
components. I’m concerned that if I restart 4D Server it will fail also.

Please help!

RE: $success_f:=PHP Execute($file_path_t;"";$result_t) intermittentfailure

[David Ringsmuth via 4D_Tech]

Paul,

It’s not possible in this application for two calls to PHP Execute to run at 
the same time.

But the default port 8002 may have some other conflict, and I had not 
considered that….

Now I will create a batch file that runs as administrator and displays port 
8002:

Netstat -aon | find “:8002 “
Pause

That should allow me to see if it is a port conflict.

Thanks!

Hello David,

We had a similar problem and there are a number of posts on the form about
it. The most common cause is you have another application using the same
port defined in the database settings PHP. If you got two copies afford the
running there will be conflict using the same php port at the same time
which is why it is intermittent. I think you can only have one PHP call 
running simultaneously.

Been down that road. I have tried running php  based sites ie Joomla! and
WordPress on Windows using IIS. They are very slow compared to a Linux.
WS2008 supports Hyper V so I would run a linux virtual machine on the server
hyper V with WordPress and run the 4D server on the host. You can create a
virtual NIC to allow the 2 to communicate. 

Rather than us an iframe I proxy the requests to redirect between the two
servers. It is transparent to the user and I use the myconnect plugin to
connect to the mysql database from 4D. Allow single logon and so on. 

see https://www.youdohome.com/ the main site is joomla and the quote page is
served by 4D. Setup is as above where joomla is running under hyperv on a
windows 2012 host.

Paul

I’ve not published any Word Press web site and would be helped by anyone here 
who has done so on  a WS2008 box.

Can it be easily done?

Are there things in Word Press that won’t run on WS2008?

If you are using 4D server this can happen when the record has been
loaded/modified on the server. Triggers run on the server. This is one way
you get this sort of situation. The other, which has bitten me before, is
when an EXECUTE ON SERVER method has loaded, but not unloaded, a record.

The data file is in use by 20+ people who are updating it. It can’t be in

RE: Benchmark Speed Test Method

[David Ringsmuth via 4D_Tech]

Steve,

In both v15.6 and v17.4 I had to put nginx in front of 4D Web Server to handle 
heavy loads.

Nginx did SSL termination, and it allows 4D to handle only the http processing.

So both 15.6 and 17.4 failed for me under very heavy loads, without a 
reverse-proxy (nginx) in front of them doing SSL termination.

user-agent html formatting on android outlook

[David Ringsmuth via 4D_Tech]

My 4Dv17/Active4D application has a web form with some minimal attribute.

Bold, Sized text with  at the line endings.

The text displays correctly on most user-agents.

On the android using the outlook application as a web user-agent. the text is 
displayed with no formatting, a large single paragraph with no line endings 

I need suggestions to fix this for the android outlook app user-agent.

Thanks!

Menubar 1

4D v17R4 2323298 64bit Remote

At the end of my startup method Menubar 1 is displayed. 

On some client machines the menu items are not “active”. When selected they do 
not run the assigned method.

On other client machines running the same application at the same time, all

method call chain and collection.indexOf

[David Ringsmuth via 4D_Tech]

For debugging I like method call chains.

Now in v17 with collections, they are easy.

Collection.push(current method name)
// method here!
$TrashThis_t:=Collection.pop()

I found while using the call chain collection that the 
collection.indexof(“Value”) does compile, but it does not work, because 
.indexOf must have a capital “O”.

This is like emca script!

RE: WritePro expression undefined

[David Ringsmuth via 4D_Tech]

Tim!

We have great support from 4D! (Erick)

This is an effective 4D tech support work-around to the problem of “Undefined”.

Here “WParea” is a 4D Write Pro object.

After running this method on our converted 4D Write to 4D Write Pro documents, 
none of the embedded statements return “Undefined”.

It wraps all embedded expressions in an ‘eval(“….”)’. I did not find “eval” as 
a 4D command, but it works!

Off-Topic: Lastly, I must conceive a way to convert the embedded picts…
//-
C_OBJECT($range)
C_LONGINT($start;$end;$i;$type)
C_TEXT($text;$Newtext)

WP SELECT(WParea;wk start text;wk end text)
$range:=WP Get selection(WParea)
$start:=OB Get($range;"start")
$end:=OB Get($range;"end")

ARRAY TEXT($methodArray;0)
APPEND TO ARRAY($methodArray;"eval")
SET ALLOWED METHODS($methodArray)

For ($i;$start;$end)

$type:=ST Get content type(*;"WParea";$i;$i)

If ($type=2)  // found expression
$text:=ST Get expression($range;$i;$i)
$text:=Replace string($text;"\"";"\\\"")
$Newtext:="eval ("+"\""+$text+"\""+")"
ST INSERT EXPRESSION(*;"WParea";$Newtext;$i;$i+1)
End if 

End for

//---

If you observe it, MERRY CHRISTMAS

RE: WritePro expression undefined

[David Ringsmuth via 4D_Tech]

Add,

4D Write expressions did not require a value to be returned, so it was 
acceptable to have embedded Query, Create Set, Intersection, Union, Use Set, 
Selection to Array, etc…, commands in the 4D Write document.

Converted to WritePro, the same expressions return “Undefined”.

It is a change in behavior that requires editing 1000’s of documents.

And WritePro does not provide an easy way to replace those expressions with a 
method call that will not return “Undefined”.

Hi David,

If you are insert an expression into a 4D Write Pro document, the expression 
should return a value.

For example:
100+90
Current date
projectMethodThatReturnAValue

For QUERY command, the execution will produce a selection of record in memory. 
It does not return a value that can be inserted to the document.

How to process all WritePro area expressions for replacement / update?

[David Ringsmuth via 4D_Tech]

I need some code that will process a 4D WritePro area, updating existing 
embedded expressions, replacing them with a different expression.

The command to get an expression, ST Get expression, works on only some 
expressions - data structure only like: [Table]Field.

Editing a WritePro area using the WP Get text returns stylized text, and all 
expressions have a “-d4-ref:’expression_here’”, but these are html and 4D 
command number added expressions.





Even if I replaced the expressions using the WP Get text and updated with WP 
Set Text, we loose embedded pictures. So this wont work for me.

RE: WritePro expression undefined

[David Ringsmuth via 4D_Tech]

John,

We opened a case with 4D.

WritePro optionally displays expressions, or their calculated values.

We may have to parse the converted WritePro objects to replace queryies with a 
call formatted like:

Query_ (->[Student];->[Student]AccountNo;"=";->[Account]AccountNo)
…which does…
QUERY($Table_p->;$Field_p->;$Operator_t;$Value_p->)

It’s a bug. WritePro should not show “Undefined” as the result of a embedded 
query expression.

SET ALLOWED COMMANDS should also work for 4D commands, since if a user is 
allowed to enter expressions, than those expressions should be restrictable.

I see two options:

1. Submit a bug/feature request to 4D and hope they change it to return nothing 
instead of "Undefined".

2. Replace all of your QUERY commands with a method that returns an empty 
string.

I don't use 4D Write Pro, but I think automating the replacement in 4D Write 
before conversion should not be too difficult. I also think it would be a win 
over the way you are doing it because having the project method shows the 
queries, tables, and fields in the design environment referencing. You lose 
that visibility by embedding queries directly in 4D Write documents.

Maybe that does not work if you have end users writing their own queries for 4D 
Write. That seems dangerous to me.

RE: WritePro expression undefined

[David Ringsmuth via 4D_Tech]

John,

WritePro documents may contain references to [Table]Field, which requires that 
the record be present during printing, which may require QUERY commands.

The embedded QUERY commands work, execute properly in WritePro.

But in place of the embedded expression is the value “Undefined”.

We have hundreds of converted documents with queries in them that worked 
correctly in 4D Write. There they executed and did not display “Undefined” in 
the 4D Write document. These should not have to be wrapped commands to work 
without an “Undefined” appearing in the WritePro document.

This in new and apparently wrong behavior in WritePro.

If this is not an error in WritePro, and if it is the intended operation of 
WritePro, then it is a warning to everyone converting from 4D Write documents.

SET ALLOWED METHODS specifies project methods allowed, not 4D commands. So 
unless you named a project method the same as the 4D command QUERY, you are 
using it wrong. And the 4D command QUERY does not return a result, so I'm not 
sure how you would use that in an expression. Of course, you can write a 4D 
project method that uses QUERY and returns a result in $0 as the result of the 
4D Write expression.

I support sites using OSX 4D Server running Active4D, some of which are

We are in the processing of upgrading to v17, which in our case requires 64 bit

4D Write Pro (WP) Area and ST INSERT EXPRESSION

[David Ringsmuth via 4D_Tech]

Insert expression and Get expression seem to not be pre-implemented in the 4D 
v17 Write Pro area.

The documentation indicates this should be managed by the developer, along with 
“Allowed Methods”.

I think the UI for this provide access to allowed tables, fields, methods and 
commands.

If you have already implemented this for a 4D WP area, would you be willing to 
share how you did it?

Thanks!

ARRAY TEXT($DeleteRecord;Get last table number)
ARRAY LONGINT($DeleteRecord_PN;Get last table number)

End use 
Use (Storage.t)
Storage.t.DeleteRecord:=$DeleteRecord_ob // this line generated the

In a 4D v15 application for Windows I want to use just one gmail account for 
authenticating all outgoing emails, but allow a variety of senders to send 
emails that are seen in the recipients' email clients as coming from the 
senders' individual accounts, not from the authentication account. I haven't 
found a way to do that. The following combination of values results in the 
SMTP_Auth username showing up as the sender in the recipient's email client:

SMTP_Auth username: auth-em...@gmail.com
SMTP_From: from-em...@gmail.com
SMTP_Sender: from-em...@gmail.com
SMTP_ReplyTo: from-em...@gmail.com

Is there a way to do this?

Connectwise (ScreenConnect) is the best replacement for LogMeIn.

Cheaper, more features.

But if you share your account, only 1 user can use it at a time. LogMeIn

RE: Converting pictures on 4D forms (Windows) to get transparency

I have used it many times to create a transparent background.

Subject: Converting pictures on 4D forms (Windows) to get transparency

Hi Everyone,

I'm in the process of going through a database to convert all the 
pictures, icons, and such in it so I can use the database with 64-bit 4D 
v16 (and eventually v17).

The documentation is pretty clear that even though any images pasted in 
did not start life as PICTS - and I'm talking about things like arrows, 
some icons, line drawings, navigation tools, etc., that are part of the 
user interface, not actual photo type pictures -  4D would receive and 
store them as PICTS, so you have to find each one and convert it.

To do this, I'm using JPR's Picture Conversion utility that he provided on 
the 2017 4D Road Tour.  It does a fine job as it can scan all the forms, 
find the offending pictures, list them, and then provides a utility where 
you can either convert them and put them into the picture library or 
convert them and put them into an external folder.
 
One thing I'm finding is that the conversion doesn't support transparency, 
so I end up with pictures that have white backgrounds, which doesn't look 
nice.  Here is part of a thread from me to JPR:

Me: When I drag a Static Picture to the converter, then back to the form, 
it seems to lose its transparency, even though the 'Transparent' property 
is turned ON.  How can this be fixed?
JPR> It cannot. The transparency done previously by 4D was just a trick 
replacing the white pixels with the background color dynamically, because 
the concept of transparency didn't exist at this time (like in PICT, JPEG, 
etc.) 
JPR> Now 4D uses the modern toolbox which relies on the picture 
transparency information coming from the alpha channel. So if you want 
transparent pictures, you must convert into a format supporting alpha 
channel (like PNG) and use any software able to add the alpha layer to 
your pictures.  On Mac, the simplest one to add alpha channel is 
PaintBrush (from Soggy Waffles). You add transparency with the paint Fill 
tool


The problem is that I'm on Windows.  Does anyone have a recommendation for 
fast technique that they've used that supports this "alpha channel' so I 
can convert my non-transparent images so that they are transparent again? 
It looks so bad having an arrow on a form with a big white background.

Thank you -

ftp://ftp.4d.com/ - and ftp://ftp.4d.com/PRODUCTS/Current/ contains v14.x 
stuff), nor is it listed at http://www.4d.com/products/4dv16.html

Search on the site didn't find anything newer than v

forums.4d.fr has always confused me, but I couldn't find it there, either.

Is there a new 4D Pack for v16, or have all the 4D Pack commands now been 
built in?

One reason to use a mailing service instead of 4D is - as I recently
discovered - if you send a large number of emails in a batch (let's say
more than 500) your service provider is likely to block them, as it may
appear that your account has been hijacked by a spammer.

I'm not familiar with MailJet so I can't speak for them, but the service we
use (Aweber) offers lots of useful features such as tracking who clicked on
which links in the emails. It would be a lot of work to do that with a
4D-generated email.

RE: Connection is broken, cannot receive request reply

[David Ringsmuth via 4D_Tech]

Tim,

Our current test for the error still going at 3h+, and there is no error.

It was the SET DATABASE PAREMETER(14;1) that kept it going without an error.

I think the problem is solved!

THANKS!

Have you found a network where the error does NOT occur?

If you have reproducible sample that causes the issue on multiple networks then 
then it sounds like the hard part is already done. I would suggest opening a 
case and submitting the sample for further assistance.

Hi David,

Do you have a managed switch on this network?,  it is possible for a switch to 
close a connection with no traffic, which could also result in this message.

The usual wisdom dictate having the timeout set to less than the switch/router 
timeout to prevent the port closing without the application knowing this.  

Cheers,

It seems like something is closing the network connection.

I searched 4D Tech on gmane, read the docs on keeping the connection open, but 
after about 15 minutes of idle time, with no user activity, we get this error 
message (above and below).

A network semaphore with a 300 ms timeout is crashing.
When we remove the network semaphore, we crash on a QUERY in a different method.

This exact same error occurs on our client’s network.

I need help fixing this one.

A serious error occurred while a request was being sent to the server. You 
should quit or restart the database as soon as possible.

Sort the selection by the Date field, take the first Date, and then goto

This avoids loading much, except the date field sort.

Greetings everyone,

Is there a way to get the earliest and latest dates from a selection of

I have sorted the data and captured the first and last dates but this seems
rather a lot of work to get this info.

I believe that I have also used Selection To Array to capture the dates in
the array and then sorted the array.

Surely there is something I've overlooked?

Currently using v13.6.

RE: NGINX Config

[David Ringsmuth via 4D_Tech]

Paul,

I can attest to the speed nginx provides in front of 4D!

But nginx also increases stability. 

Nginx will close stale connections, whereas an extremely busy 4D Server may not 
close stale connections, resulting in eventual crashing with thousands of http 
processes.

To Clarify I use nginx on windows and linux in a hyper v vm to proxy to our
different internal servers for web, testing etc. Each ssl is tied to a
domain however if you enable ssl and 443 on the nginx instance then you 
must have an ssl for each domain listening on port 443. 

It is much faster to have nginx ssl sitting in front of 4d and have proxy to

Subject: Re: NGINX Config

I am having some problems with my Nginx reverse proxy. I'm running 4Dv15,
and Active4D 6.4r3, using the 4D server shell. I have successfully
configured two web roots in Active4D, which run on the same 4D Web Client,
on port 8010. I have two different host names which are pointed to the same
IP address. I'll call them name1.domain.com:8010 and name2.domain.com:8010.
These successfully resolve to the appropriate web root within Active4D,
when I put those two urls in my web browser.

I set up my proxy in nginx two different ways, and neither of them
consistently resolve to the right website:

1: I setup one upstream server and accessed it through proxy_pass from both
server definitions:

upstream 4d_webclient{
server 127.0.0.1:8010;
}

server {
listen 80;
server_name name1.domain.com;

location / {
   root   /location_1
   proxy_pass http://4d_webclient;
   ...
}
}

server {
listen 80;
server_name name2.domain.com;

location / {
   root /location_2
   proxy_pass http://4d_webclient;
   ...
}
}

Please note that I'm just trying to get the reverse proxy to work. Once I
do that, I'll add SSL requirements, and all the necessary rewrites to make
sure people are redirected to our secured interface.

The second way I did it was to create a different upstream for each
website, using the DNS names for each, and then calling the appropriate
upstream proxy from each server definition:

upstream name1_server{
server name1.domain.com:8010;
}

upstream name2_server{
   server name2.domain.com:8010;
}

... (the same as above, except replacing 4d_webclient with name1/2_server
at proxy_pass)

Both ways gave the same results. After restarting my Web Client and nginx
(just to make sure I start from a clean slate), both name1.domain.com and
name2.domain.com resolve to the name1:domain.com:8010 website. However, if
I go to name2.domain.com:8010, then both name1.domain.com and
name2.domain.com will resolve to that website. Going to
name1.domain.com:8010 then causes both portless addresses to resolve there,
until I visit name2.domain.com:8010 directly again.

Obviously, I don't understand the relationship between how nginx deals with
upstream declarations and how that passes along to Active4D. Any help would
be appreciated.

OSX absolute and relative path

On one OSX when creating a file an attempting to launch it the path does not 
contain the Macintosh HD, it begins with file:///userName/...

On another OSX the exact same command to create the file with path begins with 
the hard drive name: file://Macintosh%20HD/userName/...

Could it be how the users are logged onto the computer?

Keep Alive Connections Number of requests by connection

[David Ringsmuth via 4D_Tech]

When running 4D Server behind a proxy server (nginx), does 4D Server consider 
all of the requests from the proxy server to be from the same connection? The 
proxy server shows only 1 process ID.

With between 500 and 2000 requests per second from the proxy server, what is 
the recommend setting for “Number of requests by connection”?

In this case both nginx and 4D Server are running on the same machine (windows).

Thanks!

RE: Folder separator constant

[David Ringsmuth via 4D_Tech]

Tim,



It seems possible to me that there is another option for the “Folder separator” 
character.

On startup the address for this character is populated with the correct value.

Thereafter it is retrieved as any other constant.

I’m guessing it is determined in runtime, most likely at startup.

I’m glad you think about such things.

Now here is a great feature implemented in the wrong way. It confuses a 
programmers logical sensibility. 

“Folder separator” constant. It is a “constant”. Constants have a single value. 
Right? 

“Folder separator” constant has whatever value it correct depending on the 
platform it is running on. If on macOS it is colon “:”. On Windows is it back 
slash “\”. 

Compile your database. Run a method on macOS and you get one value for “Folder 
constant” and a different value on Windows. Client side, server side, it 
doesn’t matter. Runtime determines the value not compiling. 

But I thought constants were evaluated and resolved at compile time. Isn’t that 
the way it works in all other programming languages? A constant is a single 
value hard coded into the program code by the compiler. 

So 4D Compiler must treat this “constant” differently from other constants. The 
4D compiler must code this as a function that gets evaluated at runtime. 4D 
what were you thinking! 

Was it so terrible to make “Folder separator” into a function like “Application 
type”? Or did some engineer have the intense need and desire to see “Folder 
separator” show up in the method editor as a constant. Damn the semantics of it 
all! It may look like a constant, but it’s not. It is secretly a function.

From a programmers point of view it sure seems like an odd decision to me. 


This has always bugged me. I just had to finally get it off my chest. :)

[David Ringsmuth via 4D_Tech]

Lee,

I’ve done a lot with nginx, very very little with apache.

I've setup apache as a front end to 4D on 'regular' macs without issue. But
now I need to do it on a Mac running the Server software and I'm not clear
where/how to configure that and my google fu is failing me.

Has anyone done that and can you point to directions?

I'd settle for having 4D serve directly, but OS X Server is running apache
even with Websites off.

https not working

[David Ringsmuth via 4D_Tech]

4D Server v15.4
Windows Server 2016
Active4D

We just installed a new cert.pem from QualitySSL.

I’ve evaluated the cert.pem with my openSSL tools and verified its good, and 
the modulus matches the key.pem.

4D Server is showing 443 open, active, but is not responding to any requests.

I’ve given the cert/key.pem to Pascal, and am waiting for a response from him.

I need ideas please!

Thanks!

RE: SMTP error 10113 Error with Authentication

[David Ringsmuth via 4D_Tech]

Tim,

Great suggestion. At first I thought it did.

The smtp auth password has only lowercase letters and numbers.

It is using SSL (true) SMTP AUTH (true).

I had that problem on another system. Special characters broke it.

David,

Just a wild guess - Is there a strange character in the password?
If so, maybe the character is being handled differently on 4D Server?
I don't know why this would be the case, I just thought it might give you 
something to investigate.

RE: SMTP error 10113 Error with Authentication

[David Ringsmuth via 4D_Tech]

I tested with plugin 15.0, both with 4D Server and 4D Remote.

4D Remote sends the message correctly.

4D Server does NOT correctly deliver the message, but I am no longer getting 
the error 10113 Error with authentication. The email is NOT delivered.

Compiled
4DIC Plugin 15.3

Also tested with:
15.4 (211153) with 4DIC plugin 15.4, Compiled

When sending emails through 4D Server at this location fail with SMTP error 
10113 Error with authentication.

Same application sending email through 4D Remote or 4D Stand Alone on same

Same application sending email through 4D Server, Remote or Stand Alone on

I’m looking for suggestions…

RE: 4D 15.3HF1 OSX 10.12.4 - is 4D v15.4 the best answer.

[David Ringsmuth via 4D_Tech]

Tim,

Thanks for responding!

We went to v15.3HF1 as a stop gap, because 15.2 was crashing on OSX 10.12.4.

Why did you not recommend 4D v15.5?

In a DOS attack posted here it performed without crashing, whereas 4D v15.4 
crashed.

Even 15.3 hotfix 1 (released 12/22/2016) is not certified for Sierra (it is 
only compatible):
http://download.4d.com/Documents/Products_Documentation/LastVersions/Line_15/VIntl/PDF_Format/4Dv15_3_HotFix1_Certif__INTL.pdf

You should really be using the "certified" release now that it is available.

4D 15.3HF1 OSX 10.12.4 - is 4D v15.4 the best answer.

[David Ringsmuth via 4D_Tech]

We’ve had 2 crashes on 4D Server with the HTTP thread.

For us this is a rather higher-volume site.

I’ve seen here 4D v15.4 seems to perform well in this area in particular – it 
survived DOS attack simulation.

We are looking for suggestions and insight.

Are there issues with 4D v15.4 that would caution upgrading to it?

Thanks!

Have you tried using ".html" instead of ".htm"?
What happens if you doubleclick your .htm-document in the finder?

It should be “open”.  (SORRY)

I am confused by this post. Your first statement is you are trying to OPEN an 
.htm document on macOS. But your AppleScript code will not open the document, 
it PRINTs it.

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!
