Re: Editing datagrid cells

[Simon Knight]

Hi Pete,

Unfortunately I don’t have any answers but I have a similar problem.  I am 
trying to detect a return in a specific field  on a datagrid form and so far I 
can either detect the return but not the name of the field (I just get the name 
of the field editor) or I can get the name of the field with no detection of 
the key press (because the keypress has gone to the field editor).

Lest hope one of the experts answers our questions….

Re: Editing datagrid cells

[Simon Knight]

I added a custom prop to store the name of the field being edited following a 
suggestion made on the Livecode forum.  I added this line to the EditValue 
handler in the Row Behavior script : set the cFieldName of grp "DgNotes" to 
pKey  -- store this for use in the custom field editor. Code in the custom 
field editor reads the value when it processes the key presses.

Please recommend a text editor

[Simon Knight]

Hi,

I have to produce some documentation and am looking for an editor (Apple 
Mac) that will support language syntax colouring.  I am experimenting 
with TextWrangler.  The complication is I want to use both Livecode and 
MS Access VBA code.


Do you have any suggestions ?

Richmond,

Many thanks - I will give textwrangler a try, I have used it as a plain 
text editor but never really dug deep: I have down loaded the 
"Revolution" add-in that you pointed me to and may have a try at 
creating my own.  The one thing I have not been able to do is to 
directly export coloured text to a word processor.  The Textwrangler 
export option remains grayed out but I can get the text by printing to 
preview and copy and paste from there.

Re: Please recommend a text editor

[Simon Knight]

I've no objection to the built in script editor (except when it bangs 
out during debug) especially as I have just re-discovered that if I cut 
and paste from it I get coloured text.  However, I want to create a 
document that compares Livecode script with VBA code and if I do a cut 
and paste from the VBA editor I get plain text.  I now realise that I 
can put the VBA through textwrangler and into a Wp such as Bean with any 
Livecode being inserted with a straight cut and paste.


Ah! Appleworks 6.  Now it comes from a time when Apple were hungry and 
software had to work whereas today it just has to look good - but please 
don't get me started.


As to  'if I want to do script editing in VBA"- well I don't really its 
just that have to ;-)

I'm not entirely sure what your objection to the built-in script 
editor is; as a syntax coloured external editor is much the same sort 
of thing.


However, having said that, I tend to use Appleworks 6 on my G5 iMac 
running Mac OS 10.5 for editing large scripts where I need to

perform bulk search-and-replace operations.

Appleworks does not offer syntax colouring, but I use it mainly by 
doing a copy-paste of an already finished script to modify it via

search-and-replace rather than programming per se.

If you want to do script-editing like Visual Basic (i.e. one long list 
rather than lots of little lists in each object) then I suppose your 
question begins
to make sense; the only real problem is at that point you lose the 
WYSIWYG aspect that is so powerful in LiveCode.

Re: Please recommend a text editor

[Simon Knight]

Richmond,

You raise some interesting and in some ways disturbing questions. Why 
are we seemingly locked into an endless cycle of replacing working 
equipment with new more expensive versions?  In early days the 
improvements were real with greater storage and improved graphics.  I 
bought my first Apple because Acorn Ltd stopped making computers and I 
could not figure out what I "needed" in a Windows PC.  Initially I was 
happy to upgrade both hardware and software as OSX improved but then 
Lion was issued and Apple entered a phase of stagnation coupled with the 
removal of features such as Rosetta.


Unlike you I have purchased a machine running MAC OS Y ("Black Hills of 
Dakota") and its quite like Mountain Lion only with blue buttons. Where 
possible I have switched off many of the "new exciting" but pointless 
features such as transparency.  The down sides have been many, most 
notable being  my new  computer will not run the older version of Apple 
Pages and the new version will not open older files, not that surprising 
perhaps but it has made me review how I store information for the long 
term.  Also, many of my home movies no longer run as the new Quicktime 
does not recognise the file formats (Its QUICKTIME you dumb piece of 
S**T!) (yes I know quicktime is a container format but why have they 
dropped old formats - have they run out of resources?).


The upshot is that I am unlikely to purchase a new Mac, especially as I 
am certain it will have been dumbed down to the level of IOS and have a 
finger painting interface included.  I suspect that I will either give 
Windows a try or take a leap into the unknown world of Linux.


I apologise for raving on and I think I did warn against getting me 
started but the bottom line is I agree with you.


best wishes

Simon

please don't get me started.


Why do you think about 8 months ago I bought a second-hand G5 iMac 
when I had the money for a new Intel iMac running Mac OS Y ("Black 
Hills of Dakota")?


1. Running 10.4.11 the G5 can run Mac OS 9 - and as, a while ago, I 
invested a lot of money in 3D graphics progs. for Mac OS 9 I'd far

rather run them than pay for their successors.

2. Running 10.5.8 with 2 GB RAM it does almost all I need for 
programming.


3. AppleWorks will be my favourite office suite forever unless 
somebody produces an exact clone than runs on Linux. It may not
have a million bells and whistles, but it does offer all I need, and 
when compared with LibreOffice, Open Office, Star Office, Think Free 
Office,
MS Office, KOffice, KingSoft Office (yes, I have tried ALL of them), 
it still looks better than all of them to me - probabaly because it 
doesn't suffer

from feature bloat.

See answers to my other posting entitled "Please release me, let me 
go." and ask yourself why, although I really DID like Macintosh computers
and the Mac OS, I didn't like Steve Jobs and his heirs, and their 
non-backwards-compatibility way of thinking.

This is a public list where the archives are
publicly
available:


Every
resource publicly available is easily spiderable.

I think all you're seeing
is what seems to me a recent uptick in the
aggressiveness of certain
spammer-controlled botnets.  I've been seeing
a lot more spam myself lately,
mostly for junk stock tips and bots
claiming to be Russian women who want to
marry an American.

There is no cure.  Spam consumes so much of our Internet
that an
estimated 5-10% of legitimate email never arrives at its destination

because all systems are bogged down trying to stay on top of spam.

Windows
still has about 90% of the computing market, and most botnets
are run on
unsuspecting end-users' machines.  The rest are often
installed on Web servers
that didn't stay on top of the updates for
their CMS frameworks.  When we
combine millions of compromised servers
with tens of millions of compromised
desktop machines, the botnets can
only win.

Sorry, don't have a "glass half
full" for this one.

Livecode and UTF8

[Simon Knight]

Hi,

I have an app that works with old fashioned text i.e. characters with a 
code value of less than 128.  Recently I enabled cut and paste and the 
app gets confused it text is pasted in with character values > 127.  I 
have done the obvious and an filtering out all characters with an Ascii 
value of >127 but in the longer term I want to convert a few high bit 
characters to a low bit versions e.g. smart quotes to dumb quotes.


Some of the text that gets pasted from my email client is in UTF8. I 
have done some web research and now know a little about UTF8.  I have 
written a routine that captures any UTF8 code patterns and passes the 
UTF string to a routine for conversion.


A UTF8 string may be between one and four bytes long and every byte has 
a value greater than 127.  I wish to extract the UTF character value and 
use the value to do the conversion.  My question is: does livecode have 
any method of converting  a UTF8 character string to either a UTF16 
string or to the numeric value of the character which I believe is the 
same if leading zeros are ignored?  For instance a smart open quote 
appears in my data as a series of three bytes : [E2-hex,80-hex,9C-hex] 
the numeric value of the character is encoded within the bits of the 
three bytes and will take some bit shifting to extract : the UTF8 string 
decodes to 201C-hex or 8220 base 10.


At present I am working with Livecode 6.7 and have read about and tried 
the uniEncode and uniDecode functions.  The description of these 
functions does not make any sense to me as they seem to be about adding 
or removing every other byte which can't work with UTF8.


I have tried various versions of the following button code attempting to 
get a result of 8220 base 10:


on mouseUp
 put numToChar(226) into tString -- E2 hex
 put numToChar(128) after tString -- 80 hex
 put numToChar(156) after tString -- 9C hex

 Set the UseUniCode to true

 put "source string :" &  tstring

 put uniDecode(tString,"UTF8") into tResult

 put CharToNum(tResult) into tNumberResult  -- seeking value 8220 
in base 10


end mouseUp

So do I have to knuckle down and start bit shifting?

thanks for reading
Simon

Anyone any experience with Livecode under Ventura?

[Simon Knight via use-livecode]

Well I've had issues with Ventura and how Livecode requests permission for 
access to Contacts and Calendar data.  Unfortunately I don't have Ventura so 
all this is second hand but hints that there are issues with how the Privacy 
Pane works.  For example a stack running in the IDE and using a library that 
requires access to Calendar fails to request permission yet the compiled 
application does.

Richmond62 is using : ProductName: macOS, ProductVersion: 13.2, 
ProductVersionExtra: (a)
Stam is using : ProductName: macOS, ProductVersion: 13.0.1, BuildVersion: 22A400

Details from a log file that Richmond62 and Stam reported in the Forum thread.  
If I understand what Richmond has written in the thread Livecode was listed in 
the Privacy Pane and was enabled but my library reported "denied".  Stam's 
Livecode is not listed and never requests access.

Re: Anyone any experience with Livecode under Ventura?

[Simon Knight via use-livecode]

Hi Matthias,

Thank you for your offer. 

I've conducted some more testing and it seems that the issue I am seeing may 
not be isolated to just Ventura.  Unfortunately not having a copy makes it 
difficult to report on what is occuring, so I will just describe what I see in 
Livecode 9.6.8 running on Big Sur.

Before starting I remove Livecode from both Contacts and Calendar in the 
Privacy Pane using two calls to tccutils.  With the library file installed and 
my stack file open in livecode I make the request for Calendar data.  The 
system should present two dialog boxes requesting permission to access first 
Contacts then Calendar.  When run in the IDE only one gets presented followed 
by a second stating that access to Calendar data is denied.  This should mean 
that Livecode is listed in the Privacy Pane but it is not.  This issue may be 
slightly different to what was being reported to me about Ventura.

I have raised a rambling bug report 
https://quality.livecode.com/show_bug.cgi?id=24054 
 and all the files are 
attached to this report.  For tests in the IDE I suggest the version of the 
stack dated 24th dec 2022 and version 1.1.54 of the library.  The built 
versions use a slightly earlier version of the stack file but the differences 
are minor.

Link to the form thread : https://forums.livecode.com/viewtopic.php?f=9&t=37540 
  beware that the URLs 
to Dropbox do work but Dropbox mangles the zips.  It is better to get the files 
via the bug report.

Simon

Re: Livecode Future

[Simon Knight via use-livecode]

One feature of the present commercial licensing is that I decide the terms and 
conditions that apply to any application I build.   What happens under the new 
licensing if I build an application either for sale or for a client and then 
some time in the future the application is duplicated, distributed and used 
without my permission or even knowledge?  Does RunRev chase me, the purchaser 
or both of us for breach of their license conditions?

best wishes

Re: Livecode Future

[Simon Knight via use-livecode]

Hi Jeff,

When I was working my use cases would have run into similar issues as you 
describe.  Most of my applications were short lived and were used by either 
defence contractors or the military themselves.  If I had ever tried to supply 
any application that "phoned home" I would have been asked to leave and never 
darken their door again.  

I suspect that if I used Livecode Create today I would end up having to prove 
that it was not contacting any remote servers so much so that I doubt that even 
being accepted as a "special case" by RunRev would cut it with the military 
security services.

Even if the application were allowed then the licensing is complex, for example 
I was once paid to support the Ten Tors race by designing and writing a 
database front end to a PostGre database of competitors which was designed to 
track team members during the two day event.  The event is run by the UK Army 
and the competitors are all teenagers i.e. children. 

The event is managed from an army camp on Dartmoor where there is no internet.  
The database front end was installed on something like fifteen computers 
situated in departments dotted around the camp such as transport and the 
medical centre.  Each department had personal accessing the database as and 
when they needed to.These people were working shifts over the time of the 
event.  Each department tended to use a single login so I have no idea how the 
number of users could be tracked.   Also the security and privacy issues were 
massive and there is no way that software that contacted or attempted to 
contact the cloud would have be allowed.  

While I'm sure Livecode will say contact us and we will sort something out, the 
fact is that having to do so just adds additional levels of complexity, 
friction and cost.  I have read and reread the licensing terms along with the 
updated FAQs but I still have no idea how the example above would have been 
charged if written in LC Create today.  For example my application used a 
database library, written in Livecode Script and licensed from Andrea Garcia.  
Does the use of third party libraries cause additional licensing issues?

Like you I think now is time to find other hobbies; the Proxxon range of mini 
tools are interesting and don't have the same licensing issues.

best wishes

Simon

Hi, as someone who came to Livecode attracted by the hook that it could be used

Re: FTP file upload with non-ascii characters in filename

[Simon Knight via use-livecode]

Hi

First I am not sure why your code replaces spaces with underscores in tFile.

Next I have an application that displays lists of filenames in a folder.  The 
user clicks on a filename and it is displayed in a browser object on the card.  
In order to get this to work I had to convert the displayed and selected file 
name to one that the OS actually uses at a lower level by using these lines of 
code:

put GetSourcefolder() & "/" & tFilename into tMyFilePath

replace " " with "%20" in tMyFilePath

replace "|" with "%7C" in tMyFilePath


I make no claims that the problem is restricted to these two characters but 
this might be a starting point.  Also different OS’s have different rules on 
the characters used in file names, so you need to account for the OS the server 
is running and google for character substitutions used in file names.

Storing Images for use by Custom Controls

[Simon Knight via use-livecode]

Is there an elegant method of storing images for use by a custom control?  I 
have tried adding the images to the custom control group but the buttons in 
copies of the first group refer back to the first group so there is no 
advantage when compared to storing the images on a card or in a folder.

best wishes

Re: Storing Images for use by Custom Controls

[Simon Knight via use-livecode]

Hi Scott,

Thank you for your replies.  I apologise for my question, I should have been 
clearer.  However, I have copied your response to my “hints and tips” document 
for reference in the future as it seems like a useful workflow to know.

To clarify my question; I have created a simple custom control that uses two 
list fields and some buttons.  I will probably want to use the control in the 
future so I am seeking a method of saving the control ready to be used in the 
future.  At the moment the png images, I use to "skin" the buttons, are stored 
on a card on a sub-stack named assets.  I do this because I am following some 
advice that Trevor Devore gave in a video some years ago and I know no better.  

The problem with this storage solution is that my custom control has components 
stored in different locations and they may well become separated sometime in 
the future.
Initially, I searched the Livecode forum and found a thread where the prospect 
of better encapsulation of custom controls was discussed and Mark W. wrote that 
he was thinking  about it.  This was a few years ago when version 6 was current 
and I wondered if any features have been added to Livecode to enable fully 
encapsulated custom controls to be written.  I realise that one answer might be 
“write a widget” but I don’t really want to take time learning a new language 
and process in an attempt to recreate a control that I already have.

I had not thought of using a customProp to store images and in truth I did not 
know it was an option so I will do some research and see what I can learn.

Thanks again and best wishes

Simon

Re: Storing Images for use by Custom Controls

[Simon Knight via use-livecode]

Well I tried using custom props but did not get very far with them.  My 
solution is to add the image files to the group and hide them behind other 
controls.  I have added the attached handler that sets the button icons to the 
values of the images in the group.  The handler should be called when the 
original control is duplicated but.  

I used the array to ensure that the handler only finds images that are part of 
the group:

on newgroup
   -- set the icons for the buttons
  
   --build an array of refs to images in the group
   repeat with x=1 to the number of images of me
  put the ID of image x into tID
  put the short name of image x into tName
  put tID into ImageA[tName]
   end repeat
   
   --now set the icons
   set the icon of button "add" of me to ImageA["imgPlus"]
   set the icon of button "SortA" of me to ImageA["imgSort"]
   set the icon of button "Delete" of me to ImageA["imgBin"]
   
   set the icon of button "SortB" of me to ImageA["imgSort"]
   set the icon of button "Remove" of me to ImageA["imgLeftArrow"]
   set the icon of button "Use" of me to ImageA["imgLeftArrow"]   
end newgroup

Re: Storing Images for use by Custom Controls

[Simon Knight via use-livecode]

Bob,

The reason I went for the array rather than a naming convention such as you 
suggest is because I have no idea how Livecode resolves the names.  I have an 
impression that it looks at the stack and works its way up through the images 
in ID order.  The upshot is that a button in a copy of the first group may well 
be using images from other groups.

I tried all sorts of syntax along the lines of image “ImgPlusButton” of this 
group but any attempts to specify the location were rejected.  My code 
associates the local image of the required name that is within the group 
container with its ID number which is allocated when the group is created.  I 
believe that the stack wide naming/ID list is also where Bernd’s code fails; 
images are indeed found but there is no guarantee that they are the images that 
are members of the group or as in one of my tests even on the same stack.

best wishes

Simon

Re: LC 9.02 Problems when displaying local PDF in stack

[Simon Knight via use-livecode]

Hi Tore,

I have spent a couple of hours hunting down Adobe Reader related  files 
scattered about in my computers Library folder and others but to no avail.  I 
suspect that the root cause is the newish Adobe Acrobat Reader DC which I 
briefly tried while attempting to solve an unrelated problem with a PDF file.  
This was the app that was inserting its self into my apps revBrowser control,  
I have removed Acrobat Reader DC and downloaded the Adobe cleaner app but my 
instance of revBrowser still requests that I locate Adobe Acrobat and fails to 
display the local PDF file.  I have also experimented with the Browser widget 
and get the same result when running LC 9.02.

So it seems that having removed Adobe Acrobat Reader DC that my code is unable 
to display PDFs in either a RevBrowser or a Browser Widget when running in 
LC9.02.  I also suspect there is a subtle buffering problem when running the 
same code in LC 8 and earlier as the app stops displaying PDFs after a source 
file is moved; I am still experimenting to see if I can determine exactly what 
is causing the problem.
 
Regards
Simon Knight

Re: LC 9.02 Problems when displaying local PDF in stack

[Simon Knight via use-livecode]

Excellent advice Tore - many thanks.

I reinstalled Adobe Acrobat Reader DC and confirmed that my app PDFreader was 
now displaying PDFs when run in LC 9.02 and that a second selection of a PDF 
caused the Adobe related menus and button bar to be displayed i.e. back to my 
starting point.

Next I ran the Adobe Cleaner App which I downloaded from the Adobe web site.  
Thus ran and reported that the Reader had been removed.  I checked the log file 
and it contained a very long list of files so this removal app is necessary.

Then I ran my app PDFrename and confirmed that it could display PDFs and 
continue to do so once the PDFs are renamed and moved all without any Adobe 
clutter.  All this works but the display of PDFs is slower without Adobe Reader 
installed and slower than with earlier versions of LC.  Unfortunately this 
slowness now occurs in the older versions so may be OS related.  It could be 
that in the past I had an older version of Adobe Reader installed that did not 
force menus to be displayed and ran faster than the native OS.

So this is a problem partially solved.  The true problem is that we can produce 
applications that use the revBrowser control which may have a UI that varies 
significantly depending on what the end user has installed on his computer.  I 
think this is undesirable.

Thanks again,
best wishes
Simon Knight

Richard,

Your are correct but Malte did ask ask about general refactoring (i think)  so 
I just mentioned my latest problem / finding.  As to the PDF “feature” itsself 
I think its now up to Edinburgh to decide what to do; I doubt that they 
intended to have Adobe menus and button bars popping up in their RevBrowser.

As to what members of this list can do the answer is to keep offering friendly 
help!

I don’t think that I am acting as a relay from the other side… 

but I do agree that the team does an extraordinary job of bug reduction while 
adding features and keeping on top of all the changes to the list of OS’s that 
livecode runs on.

I suspect that this is a fact of life especially in small teams.  My limited 
experience is that people who write code generally hate writing paperwork as 
they want to get on and complete the next task and not create documentation 
about the last.  Not forgetting that a lot of the paperwork generated by the 
big players is just shelf ware and no use to anyone except the manager who 
demanded it.

Format text data records for processing in Livecode

[Simon Knight via use-livecode]

Hi,

I have written an Applescript that reads the headers and contents of selected 
emails in Apple Mail.  I am trying to decide to simplest method of importing 
this data into Livecode to allow it to be sorted and formatted etc.  Each email 
is a record with a number of fields the largest field is the contents of the 
email and this may contain quotes, tabs and other characters.  I aim to do the 
minimum in Applecript so I don’t wish to process the data but I can use any 
output format that I devise.

A record contains the following fields : DateSent; From; To; Subject and Content


Any ideas on a simple methodology of how to format the data so that it is 
simple to process using Livecode’s chunk expressions?

best wishes

Simon

Re: Format text data records for processing in Livecode

[Simon Knight via use-livecode]

Some interesting ideas although I’m not sure why a changing separator is 
useful.  I generally attempt to stick with TSV but it won’t work in this case 
unless I parse the data to remove the tabs from the text, however I may well 
try this.  At the moment I’m trying to use a simple tagging system.  The 
AppleScript that creates the data looks like this:

-- build the data in a useful form to be read by Livecode
set tNewRec to "" & return
set tNewRec to tNewRec & "" & "Sent : " & tDateSent & 
"" & return
set tNewRec to tNewRec & "" & "From : " & tSender & 
"" & return
set tNewRec to tNewRec & "" & "To : " & tAddresseeList & 
"" & return
set tNewRec to tNewRec & "" & "Subject : " & tSubject & 
"" & return
set tNewRec to tNewRec & "" & "Content : " & tContent & 
"" & return
set tNewRec to tNewRec & "" & return

The final version will probably not add the closing tags as they seem 
unnecessary.  I have two routines that extract the fields and put them into an 
array, these make use of itemdelimiter.  It all works but the leading REC and 
FLD tags have to be ignored otherwise blank records and fields are processed.  
I think that replacing tabs and line returns in the source data and then saving 
as TSV will be simpler.

best wishes

Simon

Re: Ken Burns Effects - acceleratedRendering

[Simon Knight via use-livecode]

I have only just resubscribed to the mailing list so may have missed some 
conversations on this subject, so I apologise for hijacking this thread.  

I am interested in this new to me layer mode of “container” being discussed 
here.  I see that it is also mentioned in “This week in Livecode” : Issue 
#179 here: http://bit.ly/2W8LU5x <http://bit.ly/2W8LU5x> . I did a google 
search for more information and found this page : 
https://livecode.com/container-layer-mode-examples/ 
<https://livecode.com/container-layer-mode-examples/>  which google reports as 
from 2017 but that may be in error.

I wonder if the web page I found refer to the same mode as is being discussed 
in this thread and are the details on the page correct?

best wishes

Re: A question about openCard

[Simon Knight via use-livecode]

"Is there some simple way that an openCard handler can branch based on what 
card it is coming from?"

My solution would be to give each card a customprop named say “uCalledBy".  
Then when the app changes cards I set this prop e.g.

Set the uCalledBy of Card 42 to “HitchHikers”
Go to Card 42

Then in Card 42 ’s  opencard or anywhere else 

If the uCalledBy of me is “HitchHikers” then
   answer “Where is your towel?”
end if

Re: $1,000 Bounty For LiveCode Bug 20240

[Simon Knight via use-livecode]

I had a look to see if I could reproduce this bug, I could not but I found 
another :

May be related to "Bug 20240 - Selecting Text With A Click and Drag of the 
Mouse in the Script Editor Does Not Always Select a Contiguous Block of Text"

I have just tried to reproduce the bug reported in report 20240 and failed.  
However, I found a problem that is repeatable and may be related:

https://quality.livecode.com/show_bug.cgi?id=22195 
<https://quality.livecode.com/show_bug.cgi?id=22195>

1.  Select a block of text in the IDE.
2.  Drag down to new location and drop : the text is moved.
3.  Go to edit menu and click 'undo' :  the dragged text is deleted - ouch!

I would expect the undo command to restore the text to its original location.

I am unclear as to the status of 20240 as it is marked as resolved yet there is 
discussion about it on the groups along with a bounty.


It may help the investigation into 20240,

Simon
