Livecode 10 problems

[andyh1234]

I have an old app that still uses charts engine and works fine, but when I try to use it with Livecode 10 I get an error message to say Chartsengine needs version 3.5 or more.

Is there any chance on an update to make it work with Livecode 10?

Thanks

Hi Andy,

no problems with LC 10.0.0 on macOS 15.01.

That's not what I'm seeing, I wonder why?

AnimationEngine was reporting a similar error which was fixable since the scripts are open. ChartsEngine is, however, locked. Both were originally written by Malte Brill so I expect that the problem is caused by the same code. The current owner of chartsEngine is, I believe, Björnke von GierkeI. I’ve tried contacting him but haven’t heard anything. I use chartsEngine in two mobile apps but have started to rebuild the charting layout portion of these apps with the newer chart widget introduced in LC 10. The problem code in AnimationEngine was:

Code: Select all

if "dev" is in the environment and the version<5 then
      answer "Sorry, this version of animationEngine requires a Livecode 5.0 or higher engine."
      stop using me
      exit librarystack
   end if

If chartsEngine uses the same code then it may still run under LC 10/Create when built into a standalone... it just wouldn't work in the IDE.

Klaus, are you using the chartsEngine library and if so, which version?

As far as I know there is no code checking for versions in chartsEngine. ChartsEngine is bought through LiveCode and it is their code that does license validation. That does sometimes crap out (bad internet, their server sluggish, sometimes they accidentally disable licenses), and that is the error you'd get in that case. Therefore I am mostly assuming (not totally sure) this is a license validation problem from their end.

So if the problem persists, I suggest asking LiveCode if the chartsEngine version is properly stored in your profile on their validation server. If it is I guess we'd need to check for the cause of the problem more in depth.

Oh, actually before that, please make sure to use the latest version (1.2.1) downloaded from this forum, as it is the only one interacting with the licensing code properly.


PS: Scott when you asked this in 2022 I did answer you ("Re: chartsEngine and Livecode 10.0.0" 29 May 2022 13:57), but you never reacted again, so after following up once I assumed the problem went away on its own, are you saying you never where able to use chartsEngine again?

I only created a chart with a fresh version of LC 10.0 for testing.
No idea what the chart engine version is.

I downloaded chartsEngine 1.2.1 and started it. I gave it an old registration number and I clicked on button "use it". I got the message about "version has to be greater 3.0 etc"

Then I used the stack below to trap the "libraryStack" message for chartsEngine in a front script.
Then it installed itself as a "stack in use"

Use this very simple stack with one button that is taken for the front script and a button to install the front script and a button to remove the front script.

If you want to use chartsEngine in the IDE then you would have to first install the front script via this stack.

Kind regards
Bernd

From the image you use the chart widget, not chartsEngine.

Ah, then I misunderstood the question...

I downloaded chartsEngine 1.2.1 and started it. xI gave it an old registration number and I clicked on button "use it". I got the message about "version has to be greater 3.0 etc"

See now this confuses me: "Gave it a registration number", there is no way to enter a number in chartsEngine 1.2.1. It does not have a field to enter registration numbers at all. In fact I specifically removed that field in 1.2.1! Where do you guys get this version with a field? That said, I'm glad that you found a workaround that works for you bn. Again, for reference, this is how 1.2.1 looks (note that there is no field, also note the bottom left corner):

Bernd,
That is a great solution. Thank you!

BVG,
My LiveCode account lists various 3rd party tools but ChartsEngine is not among them.
Nor do I see ChartsEngine listed in the third party store

https://livecode.com/extensions/

Where might I find a download of the latest version? Should I contact Heather about why it doesn't show up under my account?

And (belatedly) "thank you" for emailing me back. Unfortunately, I never saw the email and can only suppose that it must have been incorrectly sorted into a spam folder that I then failed to examine carefully enough to catch.

[BvG]

Hey Scott, yeah annoying that we missed each other back then.

The downolad for the latest version 1.2.1 is in this forum. However if chartsEngine is not listed in the add-ons, it most likely means you didn't buy it through Livecode (or they forgot about you having it), and the stack will not be unlocked in the IDE. If that is the case, you'd need to contact their support to have them sort it out. If you have any proof of purchase, like an email from one of the christmas bundles RunRev used to make, or one that Malte sent you with the code, that would probably help?

Sorry for the inconvenience.

I noticed that the front-script I use to block "libraryStack" message for chartsEngine or animationEngine is too broad.

If you only want to block the "libraryStack" message for those two then change the script of button "intoFront" of the attached stack above to

Code: Select all

on libraryStack
   local tTarget
   put the target into tTarget
   if tTarget contains "ChartsEngine" or tTarget contains "animationengine" then
   else
      pass libraryStack
   end if
end libraryStack

This way it will not block the "libraryStack" message for other stacks "in use".

Kind regards
Bernd
