4D Forum preferences setup

[David Garrard via 4D_Tech]

  RE:  Can anyone add to what John advised regarding having the Discussions
and Forum content come to me via e-mail.

After logging into the 4D Forum, you can:

1) Click on your Profile icon in the upper right.
2) Click on the small "head and shoulders" icon just below it.
3) Click on "Preferences".
4) On the left hand side of the screen click on "Categories" in the
"Notifications" block.
5) Place your mouse in the "Watched", "Tracked" etc., fields and choose
"English Community", removing others you do not wish to receive.

I still have not figured out how to get a digest instead of individual
emails.  Does anyone know how?

RE: Paypal IPN Integration

[David Garrard via 4D_Tech]

Hi Sam,

I'll get a zip file out to you today.

The system was taken off line when the client elected to move to a packaged 
ecommerce solution.  Too bad, cuz my deal was 10% of $ throughput to do the dev 
work.

Yes! I was hoping somebody out there would have an already written solution, 
even if it’s 4D 2004.

David, I was headed in the direction of NTK (which is basically 4DIC on 
steroids) as it seems to be the most direct way to approach this. I don’t need 
documentation and I’m pretty sure I’ll be able to figure it out. I just need a 
roadmap.

How come it’s offline (just mildly curious)?

Anyway, I would love to take you up on your offer and would be eternally 
grateful, willing to pay for it, whatever, as long as it works.

Thanks,

Sam

RE: Paypal IPN Integration

[David Garrard via 4D_Tech]

Hi Sam,

I have a full Paypal IPN implementation written in 4D code using 4D Internet 
Commands.  If you wanted to go that route I would provide it to you "as is" 4D 
2004.

I don’t have much in the way of documentation but an experienced 4D developer 
could figure out what the On Web Connection stuff is doing without much 
difficulty.

Note that the system was running for about 4 years between 2007 - 2011 - 
billing about $500,000 of recurring subscriptions.  It has both PayPal and 
Moneris (Canadian payments) code.  

It has been offline since 2011, so I don’t even know if it works with 2019 
vintage IPN.

Thank you for the response, Narinda.

Any suggestions on where I would find that binary, and also how I would then

In other words, how to bypass using 4D’s php interpreter and use the one

RE: Win32API setup woes

I am happy to report that with the help of the NUG, I was able to debug so that 
I now have this fixed. 

It was due to an error in the way I had the various directories laid out.  Took 
me a while, but I was able to get everything aligned correctly with the 
insights from this group.

Subject: RE: Win32API setup woes

Hello Keisuke and Timothy,

I have isolated things to a simple new structure "TestDB.4db" that has one 
method that calls a couple Win32API commands.

I downloaded the latest Win32API for Github and have placed it in the \Plugins 
directory next to this structure.  There is no \Win4DX directory for this test 
setup. 

On one Windows computer this structure shows up correctly in the 4D Explorer 
and is enabled - version 8.2.2.  When I execute code with the Win32API commands 
on this computer all is good. 

On the other Windows computer this structure shows up in the 4D Explorer, but 
is marked as Disabled - need to upgrade.

Both these computers have Microsoft Visual C++ redistributables installed.  X86 
and 64bit.

Both are using v16.3 Build 16.217894 32 bit.

One thing that might be associated is that when I compile the compiled 
structure is placed in a directory entitled "STR#  10135,18", instead of 
"Compiled Structure".  I had ignored this since I am seeing the Disabled state 
of the plugin in the interpreted database, but perhaps there is some string 
resource issue that might be causing this problem. So if anyone knows how to 
fix that issue, it may address the disabled plugin issue. 

Thank you,

David

CONVERT PICTURE v17

[David Garrard via 4D_Tech]

I have some legacy pictures fields with .PICT pictures in them in my
Windows database that I am converting to v17 64 bit.  Here is my code to
convert the pictures to JPG format.

ALL RECORDS([DOCC_Document])
For ($i;1;Records in selection([DOCC_Document]))
GOTO SELECTED RECORD([DOCC_Document];$i)
GET PICTURE FORMATS([DOCC_Document]Document_Icon;$aTPictureFormats)
CONVERT PICTURE([DOCC_Document]Document_Icon;".jpg")
SAVE RECORD([DOCC_Document])
End for

The documentation suggests that this would convert the pictures in the
database to jpg format and they would lose the "ugly big cross on PICT"
replacement icon.  But I see no changes.

I must be doing something fundamentally wrong... Any ideas?

SEND PACKET in a multi-process environment

[David Garrard via 4D_Tech]

Hi all,

 

I'm encountering some -43 errors when using SEND PACKET from multiple
processes.  Windows v16.

 

I've been logging to a single log file in the past and use semaphores to
ensure I would not attempt to write to the an open file when another process
is also logging.  This works as expected.

 

But I am also writing to various other files for logging and reporting
reasons using these multiple processes and sometimes, when the processes are
executing at the same time, I am getting -43 errors - even if they are
different target files.  The SEND PACKET documentation does not specifically
mention multi-process file writing at the same time is prohibited, so I am a
bit surprised that I might have to add semaphores in this situation.

 

Have others experienced this?

 

Thank you

FW: UTF-8 and SEND HTML FILE with Tags

[David Garrard via 4D_Tech]

I have a 'good news' update on this.  With a work-around I was able to get
this working.

It seems that there is a bug in placement of multiple instances of Thai
language text - such as headers in a multi-cell table sent to a web browser
by 4D Web Server using a single 4DHTML tag for the whole table.  As reported
a couple weeks back doing this would truncate the table.  I suspect this
applies to other languages.

So to work-around, I used individual 4DHTML tags for each cell of the table
that had Thai text.  Not the best solution, but working fine now.

Hope this helps someone else.

LAUNCH EXTERNAL PROCESS AND _4D_OPTION_STOP_TOKEN

[David Garrard via 4D_Tech]

I am trying to get code that was posted in 2012 by Peter Lerch here:

 

http://4d.1045681.n5.nabble.com/Playing-nice-with-Launch-External-Process-td
5715184.html

 

to function on Windows 10 running 4D v16.3.

 

From what I can tell using the " _4D_OPTION_STOP_TOKEN" as parameter one of
SET ENVIRONMENT VARIABLE is not functioning on Windows.  

 

Does anyone have any proof that a stop token is ever created?  I have not
seen one.  

 

I wish to use the SET ENVIRONMENT
VARIABLE("_4D_OPTION_BLOCKING_EXTERNAL_PROCESS";"false") option to control
the locking up of 4D, but need a waiting system.  Peter's code looked
perfect the job, but maybe only functions on a Mac?

Subject: Re: Loading a variable into Web Area

Hi David,
Tim's suggestion of using SET PAGE CONTENT is a good one. I've noticed it's not 
great if your page is using jquery or other resources loaded from a CDN or even 
other disk files. My guess is a web area loaded by SET PAGE CONTENT doesn't 
have any context to reference the disk files. Where would it look, for 
instance, for "./my.css"? The web server has a defined root but a web area 
doesn't unless it loads from disk. My best success has been when the page has 
all its resources in the html. Which can be a little limiting.

I use, and love, web areas. Several of the primary forms in a heavily used 
database rely on them. My approach is to collect the data to be displayed into 
arrays and then use PROCESS TAGS with html templates to build the actual html. 
In Resources is the folder with the html templates, support files (css, js, 
etc.) and a temp dir I write to. I give this file a name made up of the record 
id and table so the form 'knows' where and what to look for.

To deal with the html file saturation problem I added a method to start up to 
simply clear out the temp folder. It's rare for the temp folder to have more 
than a few dozen files and they are small.

Loading a variable into Web Area

[David Garrard via 4D_Tech]

I am trying to control the content displayed in a 4D Web Area on a form and
I am forced to use external HTML documents to do this along with WA OPEN URL
passing a file path.  This works fine, but means I need to maintain 10's of
thousands of external html files just to do this.

 

It seems to me that this would be a very common use case:   code some HTML
into a text variable and then use  WA OPEN URL with a new capability to pass
a variable or field to this command.  Or perhaps a new command WA OPEN TEXT.

 

Is this something that others have able to work around more elegantly?

 

Thanks, 

David

Running 4D v15 from a Windows server resource

[David Garrard via 4D_Tech]

In a departmental environment, a client wishes to place the 4D v15
standalone executable on a network server and allow users to launch from
there in "Connect to mode" and connect to a 4D Server v15.

 

Is this advisable?  Would there be issues with the client distributed
resources?

 

Thanks, 

 

David

LINE messaging integration

[David Garrard via 4D_Tech]

Hi all,

 

I am wondering if anyone has done an integration with LINE messaging. 

 

https://developers.line.me/messaging-api/getting-started#apply_messagingapi

 

https://devdocs.line.me/en/#getting-started

 

There appears to be a requirement for HMAC-SHA256 algorithm support.

 

Thanks in advance,

 

David Garrard
