Re: Backup Settings Not Saving

[Cannon Smith via 4D_Tech]

Hi Tom,

Thanks for confirming. Yeah, it seems the other settings save correctly. Just 
this one.

Interestingly, I found the following bug fix for v17.3:

ACI0098925: "Backup settings do not save “Repeat after X seconds/minutes/hours” 
option: on Windows it is always 60 mn, on macOS it is always 0 mn (wich is 
worse because the 0 seconds will lead the backup log file to be flooded).” 
(https://bugs.4d.fr/fixedbugslist?Version=17.3)

A little different, since I’m seeing 0 seconds after each save attempt on 
Windows as well. And if it was fixed for v17.3, I would have expected it to be 
working in v17.3 HF3, so that’s confusing. Maybe it wasn’t really fixed.

Thanks for checking.

Backup Settings Not Saving

[Cannon Smith via 4D_Tech]

I just noticed that the “If backup fails… Retry after x [units]” backup setting 
is set to 0 Seconds on all my servers. It used to be 5 minutes. So I tried 
changing it back to 5 minutes and save. If I reopen the settings dialog, I see 
that it is still set to 0 seconds. The setting change isn’t being saved!

Anyone else seen this? Mac or Windows, v17 HF3.

Thanks for any help.

Another Signing/Notarization Question

[Cannon Smith via 4D_Tech]

Hi All,

Thanks to Miyako and Rob Laveaux updating some plugins I use, and other help, I 
now have all but one of my applications notarizing again since the recent Apple 
changes. The problem with the last application is that some years ago I started 
placing a small blob file (compressed XML, not an executable) just inside the 
Contents folder during a build. Of course, the recent rules don’t like files 
being inside the Contents folder.

I’m loathe to move this file somewhere else. Technically it is possible, but 
several applications rely on it so they would all have to be upgraded at the 
same time. And it affects the auto-update process itself which will cause 
issues for users trying to upgrade to the latest version.

So I’m wondering if there is a way to sign this file during the signing 
process. I’ve tried several variations of signing the file, but haven’t had any 
luck. I’m hoping someone knows of a way to sign a file like this so I don’t 
have to go down the difficult road of moving the file to another place.

Thanks for any ideas!

Re: New Notarization Issues

[Cannon Smith via 4D_Tech]

Hi Miyako,

I have all my applications except one notarizing again since Apple’s recent 
changes. I appreciate you updating the  cURL FTP and System Notification 
plugins.

The application that isn’t notarizing has some other plugins that I’m hoping 
can be updated by their authors. I’m not sure what to tell them needs to be 
changed, though. Would you have time to explain what changes are necessary to 
make plugins notarizable now?

Thanks so much.

Re: New Notarization Issues

[Cannon Smith via 4D_Tech]

Hi Erick and Jim,

Thanks for your thoughts. I’ve taken another approach which has solved most of 
my issues. Instead of navigating the package and calling LEP commands myself on 
each component, I’m now just using 4D’s SignApp.sh shell script. This handles 
all the general cases just fine. I do have some executables that I keep in my 
own resources folder which I sign manually (in code) before firing off 4D’s 
shell script. So the process looks like this:

- Strip extended attributes and remove any code signing that exists anywhere in 
the package
- Code sign the executables I keep in my Resources folder
- Call 4D’s SignApp.sh script (I’m using the one from 4D v18).
- Sent to Apple for notarization.

Doing this I’m now down to two errors:

issues": [
{
  "severity": "error",
  "code": null,
  "path": "FFE5A08083D54FDE8D0FBAB1A1E06060.zip/Herdly 
Team.app/Contents/Plugins/4D InternetCommands.bundle/Contents/MacOS/4D 
InternetCommands",
  "message": "The binary uses an SDK older than the 10.9 SDK.",
  "docUrl": null,
  "architecture": "i386"
},
{
  "severity": "error",
  "code": null,
  "path": "FFE5A08083D54FDE8D0FBAB1A1E06060.zip/Herdly 
Team.app/Contents/Plugins/cURL FTP.bundle/Contents/MacOS/cURL FTP",
  "message": "The signature of the binary is invalid.",
  "docUrl": null,
  "architecture": "x86_64"
}
  ]


I’m not surprised at the Internet Commands one and was hoping I could use the 
one from v18 which should overcome that. Haven’t tested that it works yet, but 
it sounds like Jim already did that if I understood correctly. I’m less sure 
what to do about the cURL FTP plugin. I know Miyako has it ready for 
notarization and I assumed 4D’s shell script would take care of plugins 
correctly, but maybe there is something I have to do manually with it.

Anyway, I’m much closer than I was yesterday. Thanks for everyone’s input.

New Notarization Issues

[Cannon Smith via 4D_Tech]

Hi Everyone,

A couple months ago I finally got my applications to notarize correctly. I’m in 
4D v17.3 HF3, but using the PHP libraries from v18. As you probably know, Apple 
made changes last week and my notarization code has stopped working. Here is 
one example of the errors I’m getting back now:

{
  "severity": "error",
  "code": null,
  "path": "B3A9E8C4BFA342E4B27E1E54538DEABA.zip/Herdly 
Team.app/Contents/Native 
Components/CodeEditor.bundle/Contents/MacOS/CodeEditor",
  "message": "The signature of the binary is invalid.",
  "docUrl": null,
  "architecture": "x86_64"
},

I have a log that spits out what is happening during signing. The relevant part 
is this:

> codesign --verbose --timestamp --deep  --sign Developer\ ID\ Application:\ 
> Cannon\ Smith\ \(Y5RAH3A6C3\) /Users/Cannon/Library/Application\ 
> Support/D9BE268668A4451A8FF411ADC94400CF/Standalone\ Build/Final\ 
> Application/Herdly\ Team.app/Contents/Native\ Components/CodeEditor.bundle

StdError: /Users/Cannon/Library/Application 
Support/D9BE268668A4451A8FF411ADC94400CF/Standalone Build/Final 
Application/Herdly Team.app/Contents/Native Components/CodeEditor.bundle: 
signed bundle with Mach-O thin (x86_64) [com.4d.component.CodeEditor]


Further, both "codesign —verify --verbose” and "codesign -vvv —deep —strict” 
indicate that the app is signed correctly, but notarization returns errors like 
above.

Does anyone know what I might be missing? This is very frustrating. :-(

Thanks.

Hi Peter,

Depending on how the subform is set up, it may not be loaded by then. But it

More Errors With RECEIVE BUFFER In v17

[Cannon Smith via 4D_Tech]

I’m wondering if anyone else has noticed an uptick in errors when using the 
RECEIVE BUFFER command to read from a serial port? Our application does a lot 
of serial port communication. We also log all errors. There has been a 
_significant_ uptick in errors that occur on the following line of code since 
we moved to v17:

RECEIVE BUFFER($tBuffer)

The error number reported is always -1. But if I look in the extra information 
the error is always one of these:

Error #: 995
Resource: WI32
Message: The I/O operation has been aborted because of either a thread exit or 
an application request.

Error #: 22
Resource: WI32
Message: The device does not recognize the command.

Users simply reconnect to the port and all is fine for awhile

Anyone know what might be going on?

Thanks.

Re: Rotate Picture

[Cannon Smith via 4D_Tech]

Hi John,

Here is the code from a method I use called Photo_Rotate:

  //This method rotates a picture. While it will rotate the picture to
  //any angle, this method is really expecting it to rotate 90˚, 180˚,
  //or 270˚.

C_PICTURE($1;$gPicture)
C_REAL($2;$rDegrees)  //Expects 90, 180, or 270
C_PICTURE($0)

$gPicture:=$1
$rDegrees:=$2

C_LONGINT($lWidth;$lHeight)
C_TEXT($svgRef;$imageRef)

PICTURE PROPERTIES($gPicture;$lWidth;$lHeight)
$svgRef:=SVG_New ($lWidth;$lHeight)
$imageRef:=SVG_New_embedded_image ($svgRef;$gPicture;0;0;".jpeg")

If (($rDegrees=90) | ($rDegrees=270))
SVG_SET_TRANSFORM_ROTATE ($imageRef;$rDegrees;($lHeight/2);($lWidth/2))
SVG_SET_TRANSFORM_TRANSLATE 
($imageRef;(($lHeight-$lWidth)/2);(($lWidth-$lHeight)/2))
DOM SET XML 
ATTRIBUTE($svgRef;"height";String($lWidth);"width";String($lHeight))
Else   //180
SVG_SET_TRANSFORM_ROTATE ($imageRef;$rDegrees;($lWidth/2);($lHeight/2))
End if 

$0:=SVG_Export_to_picture ($svgRef)
SVG_CLEAR ($svgRef)

HTH.

Re: Printing structures

[Cannon Smith via 4D_Tech]

Hi Alexander,

This is great! Thank you for sharing.

Just a heads up on a bit of code that won’t work in countries that use a 
decimal place instead of a comma. In the method xml_atts2ob, lines 50, 54, 58, 
and 62 convert the decimal point in the height, left, top, and width of the XML 
values to a comma. For values that have a decimal place, this can make for some 
really, really big table widths and heights!

Again, thanks. Very useful tool.

Collections and Entity Selections Cheat Sheets

[Cannon Smith via 4D_Tech]

I’ve been using collections and entity selections more lately and notice I 
spend a lot of time in the docs trying to remember what function does what. 
Some of them aren’t named very intuitively (at least to me). And I keep 
forgetting which ones return a deep or shallow copy or use a query string or a 
method. So I made a couple of cheat sheets that organize the functions in a way 
that makes sense to me. Makes it a lot faster to find the function I’m after 
for a certain situation.

Anyway, perhaps they will be helpful to some of you as well. You can find the 
PDFs here:



I’m relatively new to these functions, so if my understanding needs to be 
corrected somewhere, please let me know!

Re: Checking If Methods Are Preemptive Ready

[Cannon Smith via 4D_Tech]

Hi Dani,

I believe that preemptive capable in that context just means that you’ve set 
the method properties that way. I don’t think it means that if you tried to 
compile the code would actually work in a preemptive context. I’d be happy to 
be corrected if I’m wrong?

Thanks.

Re: Auto Updating 4D Not Working

[Cannon Smith via 4D_Tech]

Hi John,

Thanks for the suggestion. I actually use a temporary folder to place the “new” 
version before calling SET UPDATE FOLDER. But I use the same one for all my 
applications and it works for all the rest, so I doubt security issues on the 
folder is the issue.

Thanks anyway.

Hi Lutz,

Thanks for replying. I’ve been using this mechanism in several applications for 
a few years now. No problems with any of them except this specific instance. I 
can’t see that I’m doing anything different in my code than with the other 
applications. Wondering if you can remember more details about 4D not quitting

Auto Updating 4D Not Working

[Cannon Smith via 4D_Tech]

I’m having trouble with one particular app auto updating. When it should be 
quitting, it just hangs forever.

4D v17.1HF1, macOS only. (It works fine on Windows). I’m using essentially the 
same code as in several other applications, also on v17.1HF1, but this is the 
only application that doesn’t work. Also, it was working in previous versions 
of 4D, but doesn’t now. With no code changes.

Here are the symptoms.

- I’ve verified that SET UPDATE FOLDER is setting OK to 1.
- Also verified (using SHOW ON DISK) that the path used with SET UPDATE FOLDER 
is correct and points to a .app bundle.
- Verified that Updater.app is created by 4D (did this by removing it and 
seeing it put back in on the next try).
- Verified that the On Exit method is completing correctly (using the debug 
logging).
- Noticed that Updater.app is not launched, nor is an updater log file created.

I’m guessing it is hanging when it is trying to launch Updater.app, but that’s 
only a guess. Since I can’t see what 4D is trying to do at this point, and 
because the same code is working with other applications and with this 
application on Windows, I can’t figure out what is wrong. Wondering if anyone 
has any ideas I could try?

Thanks.

P.S. It also takes a fair amount of CPU until force quit.

Re: Apple Notary Service

I do have the yearly membership and find it important to get our application to

difference.

Re: Delay Worker Process

[Cannon Smith via 4D_Tech]

Hi Gabriel,

Part of what gets logged isn’t know at the time I know something needs to be 
logged. The code is easiest if I can say, “Hey, please log this situation” and 
have the actual logging happen a few seconds later. As I said, this is a quick 
a dirty injection of some logging code to track down a bug. Not the normal 
thing.

However, I changed my method of doing this yesterday so I’m not using workers 
anymore. Just a background process and some interprocess arrays. Not the cool 
new way, but it does work.

Thanks.

Delay Worker Process

[Cannon Smith via 4D_Tech]

Hi Everyone,

I’m trying to do some quick and dirty logging to track down an issue at a 
customer’s site. As part of that I need to log some information to a file, 
always on the server. I figured the simplest would be to call a method each 
time I need to log some information and pass the info to it. The method has the 
Execute on Server property set so all logging happens on the server. I don’t 
want anything tied up waiting for the logging to happen, so I have the method 
call a worker process (on the server) and pass in the relevant information to 
it. The worker is responsible to run some checks, ensure the correct file 
exists, write the information to the file, and possibly send a Slack message. 
Using a worker also ensures that a file is not being opened by multiple 
processes at the same time.

So far all this works as hoped for and was simple to code. The problem is that 
the worker process needs to run the checks a few seconds _after_ the initial 
request to log information happened. Since the worker is just in a cooperative 
process I figured I could add DELAY PROCESS. But it seems not to work.

I could re-engineer the whole thing to use a background process in a loop on 
the server and some IP arrays or a table, but was hoping to keep it simpler. 
Does anyone know how to pause a worker process for a few seconds?

This is v17.1HF1.

Thanks.

Mojave

[Cannon Smith via 4D_Tech]

I don’t believe 4D has released a version that is fully compatible with Mojave, 
unless I missed an announcement. But I’m getting outside pressure to upgrade 
from Sierra to Mojave and may have to do it anyway. From what I’ve heard, v17 
seems to work good enough for development at least in Mojave, but my main 
concern is v16r6. I’ll still need to do some development and building in that 
version for a couple months. Is anyone using that version in Mojave and could 
comment on how well it is working? (Comments about v17 in Mojave are also 
welcome.)

Thanks!

Re: Longing IDs or UUIDs as primary key?

[Cannon Smith via 4D_Tech]

I've heard lots of comments over the years talking about how hard it is to work 
with UUIDs. I’d like to offer a different perspective. I switched to UUIDs from 
longints for primary keys 7 or 8 years ago. It took some careful programming to 
migrate the datafiles in place, but it was _so_ worth it. In all that time I’ve 
never once had to type in a UUID by hand. Instead, I just added the odd tool 
here and there that lets me copy a UUID to the clipboard. Then paste it for 
searching. As for looking for a UUID in a list, it’s pretty easy to look for a 
UUID by scanning for the first 2-3 characters and then checking that the last 
2-3 characters match. In 4D list boxes, a column can be set up to show an 
ellipsis in the middle of a string (instead of the end) when a column is too 
small. This is perfect for UUID columns. Just make them wide enough to only 
show the first and last 3 characters. Just as easy as a longint, really.

Re: SVG IDs in Listbox Cells

[Cannon Smith via 4D_Tech]

Hi Arnaud,

No, I’m manipulating the picture directly inside the list box. Not as efficient 
as I like and I haven’t tried Miyako’s latest suggestion which might be more 
efficient, but the whole process only takes 1-2 milliseconds interpreted, so 
fast enough.

Here is more of the code (I’ve left out the code that handles tracking and 
hiding previously shown SVG elements:

GET MOUSE($lMouseX;$lMouseY;$lMouseButton)
LISTBOX GET CELL POSITION(lbRanchMetrics;$lMouseX;$lMouseY;$lCol;$lRow)
If ($lRow>0)
LISTBOX GET CELL 
COORDINATES(lbRanchMetrics;$lCol;$lRow;$lCellLeft;$lCellTop;$lCellRight;$lCellBottom)
$lMouseInSVGX:=$lMouseX-$lCellLeft
$lMouseInSVGY:=$lMouseY-$lCellTop
$SVGtID:=SVG Find element ID by 
coordinates(agRM_Graph{$lRow};$lMouseInSVGX;$lMouseInSVGY)
$tSVG:=SVG_Open_picture (agRM_Graph{$lRow}) 
$tRef:=SVG_Find_ID ($tSVG; SVGtID)
SVG_SET_ATTRIBUTES ($tRef;"visibility";"visible")
agRM_Graph{$lRow}:=SVG_Export_to_picture ($tSVG)
SVG_CLEAR ($tSVG)
End if

Re: SVG IDs in Listbox Cells

[Cannon Smith via 4D_Tech]

Hi Arnaud,

Thanks for those. I ended up doing it in a pretty simple way. Basically, in the 
list box On Mouse Move event:

GET MOUSE($lMouseX;$lMouseY;$lMouseButton)
LISTBOX GET CELL POSITION(lbRanchMetrics;$lMouseX;$lMouseY;$lCol;$lRow)
If ($lRow>0)
LISTBOX GET CELL 
COORDINATES(lbRanchMetrics;$lCol;$lRow;$lCellLeft;$lCellTop;$lCellRight;$lCellBottom)
$lMouseInSVGX:=$lMouseX-$lCellLeft
$lMouseInSVGY:=$lMouseY-$lCellTop
$SVGtID:=SVG Find element ID by 
coordinates(agRM_Graph{$lRow};$lMouseInSVGX;$lMouseInSVGY)
//Manipulate $tSVGID attributes
End if

Works like a charm!

Re: SVG IDs in Listbox Cells

[Cannon Smith via 4D_Tech]

Thanks for everyone who commented on this.

It is actually _almost_ doable. With some math it is possible to figure out 
where the cursor is over a particular picture cell and "SVG Find element ID by 
coordinates” works in this context. For example:

$tID:=SVG Find element ID by coordinates(agRM_Graph{1};$x;$y)

returns the ID the mouse is over.

The part that does not work is the command SVG SET ATTRIBUTE. For example:

SVG SET 
ATTRIBUTE(agRM_Graph{1};"Value1";"fill-opacity";"1";"stroke-opacity";"1”)

does not work. This kills an idea I was _really_ hoping would work. Sigh.

I find it interesting that SVG Find element ID by coordinates works and SVG SET 
ATTRIBUTE doesn’t work in this context. It seems logical to me that either they 
would both work or neither would work in this context.

SVG IDs in Listbox Cells

[Cannon Smith via 4D_Tech]

You know how you can give SVG elements IDs and then use SVG Find element ID by 
coordinates during a click or mouse over event to figure out what element the 
mouse is over in an SVG picture? I’d like to do this, except that the SVG 
picture is in a list box. In fact, the list box has several of these SVG 
pictures in different rows and columns. So I need to detect which cell the 
mouse is over and then which SVG element within the cell the mouse is over.

There are a lot of pieces to this puzzle, some of which might not work in a 
list box context. Mainly I’m wondering if anyone has already tried this and 
proven that it _can’t_ work before I waste time working on it. Or if anyone has 
gotten it to work, I’d love to know that as well!

Thanks for any comments.

Re: collection.min() Returns Null

[Cannon Smith via 4D_Tech]

Hi Christian,

Thanks. The values are a series that need to be graphed. Some values in a 
series may be null, indicating that the graph line should be skipped at that 
point since we don’t know what the value is. That’s why I decided to use 
C_COLLECTION instead of ARRAY REAL to hold the values. As I build the graph, I 
need to know the min and max values in the series.

Yes, I can loop through the collection, of course. I just figured the 
collection probably had a function that would allow me to reduce the collection 
to non-nulls before applying .min() or .max() without having to loop. Trying to 
learn how to use all the collection functions.

Re: collection.min() Returns Null

[Cannon Smith via 4D_Tech]

As a follow up, I thought I would try to remove the null’s from the collection 
use collection.query(), but I don’t know what to use for the query string since 
there are no named object properties in the collection.

$cTest:=New collection(100;200;Null;80)
$lMin:=$cTest.query("#null").min() //<—What should the query string be? 
Or should I be using a different function?

Anyone know what I should be doing here?

collection.min() Returns Null

[Cannon Smith via 4D_Tech]

I was surprised that the following code tries to return null instead of 80:

$cTest:=New collection(100;200;Null;80)
$lMin:=$cTest.min()

I would have expected that a Null value in the collection would be ignored when 
looking for the minimum value.

Is this what others are expecting or is this a bug?

Re: POW Function

[Cannon Smith via 4D_Tech]

Hi Spencer,

Yes, it is! So simple. Thank you.

Perhaps some more help from someone? I’m trying to translate some code on the 
web into 4D. Here are the lines of code along with an explanation:

range = max - min;  
exponent = int(log(range)); 
magnitude = pow(10, exponent);
//So, for example, if your range is from 50 - 1200, the exponent is 3 and the 
magnitude is 1000.


In 4D I’m doing this:

$rRange:=1200-50
$rExponent:=Int(Log($rRange))
$rMagnitude:=10^$rExponent

But I’m getting an exponent of 7 instead of 3. Any ideas what I’m doing wrong?

Thanks.

I agree, it does make sense. I looked all over in the SVG documentation in the

might I ask about adding that to the documentation as I think it would be

Re: SVG Shape With No Background

[Cannon Smith via 4D_Tech]

I guess I just needed to hit the Send button to figure it out. It turns out 
that I can pass “none” as a color. I don’t see it in the documentation 
anywhere, but the SVG component must just pass it through to the SVG layer. So:

$tRef:=SVG_New_circle ($tSVG;200;200;100;"red”;"none";10) 

gives me a circle with no background.

So, never mind! :-)

SVG Shape With No Background

[Cannon Smith via 4D_Tech]

Hi All,

What is the best way to draw a shape (circle, rectangle, etc.) without a 
background using the SVG component? I tried using a “transparent” color:

$tRef:=SVG_New_circle ($tSVG;200;200;100;"red";"white:0";10) 
//“white:0” = transparent

But it seems that if you pass a color like “white:0” where the transparency 
part after the colon is 0, it is ignored and the fill-opacity attribute is not 
set.

I can call SVG_SET_OPACITY after creating the shape and it will set it 
properly, but I wasn’t expecting to have to call another command to remove the 
background of an object. Is this the normal way of doing it? Is there a special 
color I can use that denotes transparent? Is “white:0” not working considered a 
bug?

Or is trying to set the transparency the wrong way to do it? I guess at the end 
of the day what I’m really after is for the XML to end up with this attribute:

fill=“none”

What is the best way of doing this?


Thanks.

Thanks. I’ll go get the new version now and give it a try.

From your example on github, is this how you would move “c” up a level?

OB SET($options;\
"URL";"ftp://ftp.example.com/a/b/c";\
"USERNAME";"user";\
"PASSWORD";"pass")

$name:="ftp://ftp.example.com/a/c” //A full path here???

Moving Files With cURL FTP

Does anyone know if Miyako’s cURL FTP plugin can move files? I need to get a

and I’m not quite sure how to do that with his plugin.

Fastest Feature Request Implementation Ever

[Cannon Smith via 4D_Tech]

Some of you may know that I use a mechanism in my windows where each window and 
widget on the window has its own “model” object. This can be passed into a 
window and then manipulated after the window closes. This logic applies to 
subforms as well and is set up so that when a subform is typed as a C_OBJECT, 
the subform container’s variable is also the subform’s “model” object. This is 
a _really_ handy way to work with subforms while keeping data associated with 
them part of the main window’s model.

Since 4D has implemented the “Form” object, I wanted to switch to using that 
instead of my hacky mechanism. The only problem is that I really wanted it to 
continue working with subforms in the same way as I’ve been doing it in the 
past. So I started to write up a feature request where, if a subform is typed 
as a C_OBJECT, then the subform container variable could be the same reference 
as the Form object from within the context of the subform.

As I was doing that I needed to double-check something about Form in the 
documentation and guess what? I found that 4D had already implemented Form in a 
subform context exactly as I was going to request! Fastest implementation of a 
feature request ever!

Thanks 4D. :-)

Re: Styled Text and QPDF Plugin

Hi Kirk,

Yes, I did talk to Rob. He was the one that directed me to the QPDF Draw Text 
command and the embedded possibilities. I was thinking the same as you—that it 
should be possible, but a lot of code. That’s why I was asking if anyone had 
already tackled it. I’d be willing to trade some code with anyone who had done 
this.

I can’t answer this for Justin, but we have both kinds hitting this bug. Some

Re: Difference between OB Copy and :=

[Cannon Smith via 4D_Tech]

The neat thing about objects, in my opinion, is that they are reference based. 
I would try to stay away from using OB Copy unless it is warranted. For 
example, in your example you could just use the field directly or a reference 
to the field. Unless you save the record, changes won’t be put back in the 
database anyway.

However, be aware of a bug in 4D. If you modify a child object in an object 
type field and then save the record, the object will not be saved. It is only 
saved if you modify a top level key in the object. The workaround, until 4D 
fixes this, is to assign the object field to itself before saving.

Re: Difference between OB Copy and :=

[Cannon Smith via 4D_Tech]

> [Letter Templates]WP_SeriesPictures:=oPictures  

Both [Letter Templates]WP_SeriesPictures and oPictures point to the same 
C_Object instance in memory. If you change either one, they are “both” changed.


> [Letter Templates]WP_SeriesPictures:=OB Copy(oPictures)

 [Letter Templates]WP_SeriesPictures and oPictures now point to completely 
separate C_Object instances in memory. If you change one, the other is 
unaffected.

A deep copy means that if the object being copied has child objects (and 
grandchildren, etc.), they are all copied as well. It is then safe to modify 
any level of object knowing you won’t modify the original object.

Re: Delay process bug

[Cannon Smith via 4D_Tech]

We just released a new version of our software a week and a half ago. In this 
version I added a palette window on the server which runs On Timer. I also 
added code to most every background process which updates some information 
every time it wakes up from a Delay Process call. The palette window checks 
this information and, if it sees a process that has been asleep longer than one 
minute, resumes the process and sends us a Slack message identifying the server 
and process that was asleep. If the process does not get resumed, another Slack 
message is sent so we can handle the issue manually before our customer knows.

Interestingly, this mechanism was triggered on Sunday morning at 1:01 AM for 9 
servers. All 9 reported one or more stalled processes within a 60 second time 
period.

Re: Build with code signing

[Cannon Smith via 4D_Tech]

Hi Wayne,

The point of that comment was that nothing should change during the build 
process after signing and before distributing to the user. Once macOS has 
checked the code signing before running on the user’s machine, it doesn’t seem 
to care if it changes again.

Of course, it is only a matter of time before that changes. I keep encouraging 
4D to finish the job and ensure that nothing in the application bundle needs to 
change when running. I would encourage everyone that cares about this to ask 4D 
to make this a priority.

OBJ Module and Date Issue

[Cannon Smith via 4D_Tech]

If anyone is using the OBJ module in v16r6 or v17, please be aware there is a 
bug in 4D (reported as ACI0098267) that causes problems with dates. The OBJ 
module stores dates in an object as a string in the format “2018-05-24” and 
handles the conversion back and forth as necessary. If the object gets 
converted to a blob (OBJ_Save_ToBlob  or OBJ_Save_ToGZIP), when it is converted 
back to an object 4D is inexplicably changing the string value from 
“2018-05-24” to “2018-05-25T06:00:00.000T” which really messes up the 
conversion logic inside the OBJ module.

The workaround is to change line 20 of OBJP_ConvertToDate to check for a length 
>= 10 instead of just = 10.

HTH.

Re: Analyzing .4BL Files

[Cannon Smith via 4D_Tech]

Thanks Chip, Randy, and Jeff. Thanks to your suggestions I was able to track 
down something that I should have know but did not. The RESTORE command will 
convert a .4BL to a .journal file. From there I can use the MSC to look at it 
or, even better, the LOG FILE TO JSON command which is nice for 
programmatically looking for certain information.

Thanks much!

Analyzing .4BL Files

[Cannon Smith via 4D_Tech]

You know how you can open the MSC, go to Activity Analysis, and the Analyze the 
current log file? And export it to text? I need to go through a similar process 
with some log files that were backed up, but without integrating them. In the 
MSC there is a Browse button, but it won’t let me choose a .4BL file. Is there 
a trick to getting it to realize the .4BL file is a log file? I tried just 
changing the extension to .journal, but that didn’t work. Any ideas?

Thanks.

I’m not sure why that would be the case as it has worked for me. Perhaps a clue

Never mind. I just needed to hit “send” so I could find my own answer!

64 vs 32 Bit 4D

[Cannon Smith via 4D_Tech]

I’m currently using 4D v16r5, Mac and Windows. I’m using the 64-bit versions 
across the board. I may need to drop back to 32-bit for clients and standalone 
for a little while.

I can’t seem to remember or find if there are any features (besides the network 
settings) that are 64-bit only. Does anyone know if there are features I may be 
forgetting about?

Thanks.

Re: Constants - Can I make a Date Constant?

[Cannon Smith via 4D_Tech]

Only longs, reals, and strings. Not even booleans are allowed.

Re: Picture Madness

[Cannon Smith via 4D_Tech]

Hi Douglas,

You can do this in code. For example, here is some code I use:

GET PICTURE METADATA($gPicture;TIFF orientation;$lOrientation)
Case of 
   : ($lOrientation=1)  //Normal, no rotation needed

   : ($lOrientation=8)  //Left 90˚, so need to rotate right 90˚
  $gPicture:=Photo_Rotate ($gPicture;90)

   : ($lOrientation=3)  //Upside down, so rotate 180˚
  $gPicture:=Photo_Rotate ($gPicture;180)

   : ($lOrientation=6)  //Right 90˚, so need to rotate 270˚
  $gPicture:=Photo_Rotate ($gPicture;270)

   Else   //The other orientations are not supported. They involved flipping 
the image. Ever occur?

End case 


The Photo_Rotate method is as follows:

  //This method rotates a picture. While it will rotate the picture to
  //any angle, this method is really expecting it to rotate 90˚, 180˚,
  //or 270˚.

C_PICTURE($1;$gPicture)
C_REAL($2;$rDegrees)  //Expects 90, 180, or 270
C_PICTURE($0)

$gPicture:=$1
$rDegrees:=$2

C_LONGINT($lWidth;$lHeight)
C_TEXT($svgRef;$imageRef)

PICTURE PROPERTIES($gPicture;$lWidth;$lHeight)
$svgRef:=SVG_New ($lWidth;$lHeight)
$imageRef:=SVG_New_embedded_image ($svgRef;$gPicture;0;0;".jpeg")

If (($rDegrees=90) | ($rDegrees=270))
SVG_SET_TRANSFORM_ROTATE ($imageRef;$rDegrees;($lHeight/2);($lWidth/2))
SVG_SET_TRANSFORM_TRANSLATE 
($imageRef;(($lHeight-$lWidth)/2);(($lWidth-$lHeight)/2))
DOM SET XML 
ATTRIBUTE($svgRef;"height";String($lWidth);"width";String($lHeight))
Else   //180
SVG_SET_TRANSFORM_ROTATE ($imageRef;$rDegrees;($lWidth/2);($lHeight/2))
End if 

$0:=SVG_Export_to_picture ($svgRef)
SVG_CLEAR ($svgRef)

HTH.

Re: Collection.orderBy()

[Cannon Smith via 4D_Tech]

Thanks Jeff and Julio. Funny, I thought I’d double-checked case, but apparently 
not well enough! As soon as I changed it from “orderby” to “orderBy” it started 
working.

BTW, I finally turned on object notation in my database and have started using 
object notation as well as collections directly inside my code. So so nice! 
Easy to read and use and I’m finding I use a lot less local variables as well. 
I can’t wait until they get the AST working so the method editor can do 
checking and better type-ahead as I go!

Re: Collection.orderBy()

[Cannon Smith via 4D_Tech]

Hi Jeff,

Yeah, the ending quote must have been converted by my mail app. It’s a proper 
quote in code.

I _think_ the asc should be inside the double quotes. But I’m just going by the 
examples found at:


http://doc.4d.com/4Dv16R6/4D/16-R6/collectionorderBy.301-3690504.en.html.

I don’t really know where else to try putting it???

Collection.orderBy()

[Cannon Smith via 4D_Tech]

I’m having trouble with the collection.orderBy() command working. Not sure if 
it is me or a bug. I’m using 4D v16r6, 64-bit, on macOS with this line of code:

$cSortedFrames:=$oPage.frames.orderby("position.zIndex asc”)

In the method editor everything colors correctly, including “orderBy” which 
turns green and is italicized. $cSortedFrames has been declared as a collection 
and $oPage.frames is also a collection of objects, each one of which has a 
numeric value at “position.zIndex”. The code also passed a syntax check.

But when I actually run the code, I get an error: -10729 Unknown member 
function. It displays the line of code with the “(“ after orderBy shown in red.

Has anyone else gotten orderBy to work on collections in v16r6? Can you see 
anything obvious I’m doing wrong?

Thanks.

Re: MSC Warnings

[Cannon Smith via 4D_Tech]

Yes, it runs fine. I’d just like to get rid of the warnings.

I’m wondering if there was a time (v15?) when the object properties allowed 
setting a stylesheet on thermometers. Now that’s been fixed, but my structure 
still has a stylesheet attached to the thermometer, so it throws an error. The 
problem is that I can’t get at it to fix it.
