Re: LC Server & Server Based Stack?

[Rick Harrison via use-livecode]

I really wish the copy to clipboard thing would have worked because it
would have been a very simple solution for a personal application I
wanted to work on for myself.

I will endeavor to learn about sockets etc. even though that is
more of a learning curve here. I would rather have found
something simple, but unfortunately the things one thinks
should be simple usually turn out to be harder than imagined.

Thank you Richard and Mike for pointing out the resources
that I need to conquer!

Re: LC Server & Server Based Stack?

[Rick Harrison via use-livecode]

Hi Mike,

Ok, so the server and my open LC stack are using
different engines or are different “instances”.  If they
are on the same computer it seems to me that one
might be able to get the two to talk to each other
through the computer system’s clipboard in theory.

I haven’t had much luck with getting the contents
of a variable into the clipboard on the server side
yet.  It keeps throwing weird errors at me.
Can you think of an easy way to do that?

Thanks,

Rick

Re: LC Server & Server Based Stack?

[Rick Harrison via use-livecode]

Hi Mike,

This seems a little crazy to me.  

I can have two stacks open in memory in LiveCode, and I 
can send a message such as “mouseUp” from one stack 
to a button in the other stack. The button in the other stack 
outputs some messages to the message box and puts a 
message in a field on that stack and that all works just fine.
I’m able to view both stacks on the screen at the same time.
(This is as it should be.) 

I send the same message from the server to the button
and the messages which normally go into the message box 
end up in the display of my browser which seems a little strange but Ok
I can accept that.  The other message which was supposed to
go into the field never gets to the field which makes it look
like the button ignored that statement completely although
it executed everything else it was asked to perform.  That
message doesn’t seem to go anywhere as it doesn’t even
end up being displayed in the browser and ends up in the
bit bucket in the sky.  (Again, I can see the open stack
on the screen at the time that I tell my browser to execute
the server code.) Shouldn’t a message be a valid message
no matter where it comes from? (Hence my crazy feeling
about the whole thing.)

So you are telling me that I can send a message to closed
stack to modify it, that I should save it after the change, and
then reopen the stack to view the change - yes?

The file communication idea makes things a little more
complex but is certainly doable.

I’ve never done anything with sockets - are there any good
examples out there you can point me to for this?

Thanks,

Rick

Re: LC Server & Server Based Stack?

Hi Bob,

The LC Dictionary shows AppleScript commands are for the desktop only - so 
probably lcServer can’t do it.
If there is anyone on the list who has had success having lcServer send 
AppleScript commands please feel 
free to chime in!

Re: LC Server & Server Based Stack?

Hi Mike,

Ok, the put message in the stack showed up in my browser
so that worked fine.  My next line of code I tried was:

put "I hope this worked!" into field "TestFirstNameField1" of card 1 of this 
stack

It didn’t put anything into that field.  I also put the same code into a button
on the stack to test it, and the button works fine with the same code.
Why doesn’t this work?

Re: LC Server & Server Based Stack?

[Rick Harrison via use-livecode]

Hi Mike,

Sorry I was out for dinner..

> How do you know it didn't work?


I know it didn’t work because I looked at the stack and no changes
had occurred in the stack.  (As in nothing new was put into the field.)
I’m not looking for the change to occur in the browser, that’s not
where I’m expecting to find any change thus far.

Should I not have the stack open that I’m trying to send the
messages to?  Should it be a standalone that gets saved
after every change?

> Mind if I ask what you're looking to accomplish?


I’m just trying to explore various possibilities and directions project-wise.
I don’t have a definite plan at the moment.  I’m just trying to see what
capabilities exist in using the server to communicate with stacks.

Thanks,

Rick

Re: LC Server & Server Based Stack?

[Rick Harrison via use-livecode]

Hi Mike,

I was able to get your example to work fine,
so it proves that I’m touching the stack Ok,
but when I try to send a message to a 
handler script in the stack it doesn’t execute
the handler.

Example:

send “executeThis” to stack “teststack”

In the stack script of “teststack” the contents of
“executeThis”:

on executeThis

   answer "This is the script in the teststack”

end executeThis

I looked at the stack..
..and the stack did nothing.

What am I not doing properly here?

Thanks,

Rick

Re: LC Server & Server Based Stack?

[Rick Harrison via use-livecode]

Hi Jacque & Stephen,

Right now I’m running LC Server version 8.1.2 as it
is supposed to be set up from the mothership’s
perspective.

I’ve been looking at Jacque’s site.  The information there
seems a little old and dated.  Is the information there still
current enough to work?  

It also looks like the server as it comes from the company
is not set up as CGI out of the box, so I’m assuming that
I have to set it up according to Jacque’s website so that
whatever stack I designate with the "start using Stack (pathname)”
will work.

I’m surprised that the official LiveCode website doesn’t have a lot
more documentation and examples with a few example
images.  It looks like Jacque’s website is better although it
too lacks images.

From what I’m reading, what I’m looking to do sounds possible,
yet the example resources seem to need some updating before
it will all work as promised.  Suggestions?

Thank you for your help on this.

Rick

Re: save stack as filename failing most of the time

Hi Mike,

Using your code in the button shows in the message box
TestSaveStack

Which is the name of the file.

Searching my entire hard drive doesn’t show 
any file named “TestSaveStack”.

There is no error reported for "the result”.

Re: save stack as filename failing most of the time

[Rick Harrison via use-livecode]

Hi again,

Ok, so first looked at the settings for the defaultFolder,
and then I set the defaultFolder to where I wanted
everything to be saved.  I chose to use my desktop
to be super easy.  

It turned out that the defaultFolder somehow strangely
got set to a RunRev Application Support folder within
the Library folder, and yes it was a hidden folder, so
that did explain why the search of my hard drive didn’t
reveal the location of the newly created stack.

So upon choosing and setting the default folder to
be the desktop, the stack then saved as promised
to my desktop to my great relief.

Thank you folks for your help and patience on this!
No need for a bug report.

Hi again,

1. Create a new stack

2. Put a button on it.

3. Edit the button to insert the following code:

on mouseUp

save this stack as  “TestSaveStack"

end mouseUp


4. Test the button

It just doesn’t work at all.  No stack gets saved!

I’m using LC Indy version 8.1.2

Re: LC Server & Server Based Stack?

[Rick Harrison via use-livecode]

Hi Mike,

I’m looking at all options here.  So yes, I’d like to 
be able to do the first option, and would like to
know if the second option is possible, and if there
are any examples out there for it.  Both animals
would be welcome in the barn so long as they
can co-exist with each other.

Thanks,

Rick

LC Server & Server Based Stack?

[Rick Harrison via use-livecode]

Hi there,

I’m trying to find out if anyone has ever
gotten a LC server to successfully interact
with a LC Stack running on the same server
such that one can read and write information
to fields on such a stack.

If so, could you please point me to some good
examples or other resources for this?

Thanks,

Rick

Re: Overlaying on video

[Rick Harrison via use-livecode]

Hi Ben,

To try to answer the second part of your question first.
I think once a movie starts playing other LC messages don’t
have time to be sent. The video just takes over because
it’s showing each frame quickly so your eye tells you
it’s a movie.

One solution I had to use in the past to make a decent
animation was to break the movie into each frame and
then put each frame onto each card.  I had a short
movie so it ended up being 254 cards.  It was for iOS
so I needed to optimize for a cell phone processor.
Then I was able to have a graphic which appeared
on every card move on top of the changing cards.
So my animated character was able to move around
freely on top of a video background.  I was able to
adjust the timing of the loops so it looked pretty good.

Regarding the first part of your message:
I’m trying to duplicate some of your experience here.

I tried importing a Quicktime movie which had the .mov suffix into LC.
I put a graphic on top of the movie and when I went to play the movie
the movie put itself on top of the graphic.  So what to I need to do to
recreate your solution?

Thanks,

Rick

Re: Transparent Images in LC

[Rick Harrison via use-livecode]

Hi Paul,

I’ve used .png images with transparencies with no problems before.
It almost sounds like the alpha-channel information is getting lost
somehow.

What program are you using to create your images?

Good luck tracking it down!

Re: Transparent Images in LC

[Rick Harrison via use-livecode]

Hi Paul,

I just took one of my old transparent .png images that I used 
to use a couple of years ago and imported it as a control into an 
LC 8.1.3 stack.  It worked just fine.

I think I might have created it with “Graphic Converter” for Mac.
If you put one of your images into a “DropBox” account with
a link for me I could take a look at it for you, and see if I can
find anything wrong with it.

Re: Mysterious customer

[Rick Harrison via use-livecode]

Hi Roger,

I think you have hit upon the real problem,
and the correct solution. If he is looking at
 his Mac at a resolution of either 1024 x 640 
or 1280 by 800 then Richmond’s app wouldn’t 
fit at all properly on the screen.

For my everyday use I usually have my screen
set to 1280 by 800 because I don’t like
the small text.  When I work on an app
I always switch to 1920 by 1200.

Good catch!

Rick


That sounds like the answer

So the answer is - only in a stack.
Perhaps the dictionary should have

It works just fine here.
I’m using LiveCode 8.1.3
in MacOS Sierra.

I was able to do it both manually and programatically.
Here’s the code.

on mouseUp
set the textStyle of field "TextField1" of this card to italic

put "Hi there" into field "TextField1" of this card

end mouseUp

Good luck!

LC Server - Smart Interactive Fields?

[Rick Harrison via use-livecode]

I was wondering if anyone has come up with a way to create
 “Smart Interactive Fields” in LiveCode server without
having to use javascript?

For example:  The user types in a number in the wrong format
into a field and the field is smart enough to interactively tell the
user with a tool-tip or other pop-up instruction that says the
correct format is $999.99 or perhaps automatically corrects 
the problem for them.

Any ideas?

Thanks,

Rick

Re: LC Server - Smart Interactive Fields?

[Rick Harrison via use-livecode]

Hi Richard,

I was afraid you’d say that!  LOL

I think I’m stuck with JavaScript then according
to what you’ve explained here, and for what I 
need to do.  A web app just won’t cut it.

Thank you for investing your time into the verbose explanation.
I’m sure other users in addition to myself will find it useful.

Thanks again,

Rick

P.S.  I think LiveCode could make more money if they
invested somewhat more into these other technologies.

Re: align field scrolls

[Rick Harrison via use-livecode]

Hi Nicolas,

Does the number of lines increase or decrease between executions?

Have you tried to add or subtract a constant to adjust for the difference?

Re: Passing Variables in a non-CGI LC Server?

[Rick Harrison via use-livecode]

Hi Richard,

Ok, let me clarify if I can.  LC Server as it
is installed out of the box without setting
it up as it used to be set up in the old days.

I have three webpages.  The first accepts
the user’s input into various fields and then
passes that information to the next webpage
through the user's web browser.  That works
fine.  Then without writing those parameters
out to a database, I want to pass those
now hidden parameters to the next webpage
for further processing before writing those
values out to the database.  

How are people handling that process?  
Or am I forced into writing everything out 
to the database and then reading it all 
back in just to go from one page to the next 
to the next?

Thanks,

Rick

Re: Passing Variables in a non-CGI LC Server?

[Rick Harrison via use-livecode]

Hi Matthias,

Yes, I want to output some information to the user, and other
information remains hidden - where some data is adjusted,
modified, on the third webpage.

No, I’m not looking to redirect to another webpage, although
I have used that technique in the past on other types of
webservers.

I’d rather not have the parameters put into the URL where
the user can see it if possible for security reasons, but
if that’s the only way I suppose I could encrypt it before
passing it through that way.

Thank you for your input!

Rick

Re: Passing Variables in a non-CGI LC Server?

[Rick Harrison via use-livecode]

Hi Matthias,

Yes, that was what I was trying to do with no luck getting that working.
I can get it to work from a client-side stack without any issue, but
when I try to move that code into a .lc web script page it won’t work.
So, that’s why I decided I’d better ask what others are doing to pass
information along.

Thanks,

Rick

Re: Passing Variables in a non-CGI LC Server?

[Rick Harrison via use-livecode]

Hi Mike,

Yes, I’m hitting lc server script pages directly in the browser though
a web server.

Yes, all of my pages are .lc based.

I looked at the link you suggested for session management.
I put the code exactly as it was to see if the example would
work.  It doesn’t work.  As soon as it gets to "start session”
it gets flagged as an error at that line in the browser.
All I get is the line number in the code for the error.
file “/blah/blah/TestFile2.lc
 row 30, col 1:  (Which is for "start session”)

Ideas, suggestions?

Thanks,

Rick

Re: html5 feature list anywhere? sqlite? local file access?

[Rick Harrison via use-livecode]

Hi Dr. Hawkins,

I didn’t see that anyone answered your question yet so
I thought I’d take a stab at it.  Others can please feel
free to correct me if my information is too old or whatever.

HTML5 as I understand it in it’s current form is still
considered “experimental” according to the LiveCode
team.  It is not able to interact with things outside of
itself like external databases, files, etc.  The new
Java Native Interface available in LC version 9.0.0 DP 6
and later maybe able to let you communicate via Java
with external databases.  I haven’t played around with
that version yet to see if it works or not.

HTML5 will work for creating self-contained stack apps 
which don’t require any external access to files or databases.
It will allow you to have your users download the stack/app
through the web-browser, and then run the app in the
browser, but the app then resides on the client side
of things and any information you need is internal
only for the stack/app.

For me it made more sense to just have different versions 
of my stack available for download for whatever platforms 
my users need.  I have one for Mac, one for Windows, etc.  
That way my stack app has the full functionality of LC, and 
it can talk to whatever external files or databases I want it 
to access.

I hope that helps!

Re: OT: Hackintosh

[Rick Harrison via use-livecode]

Hi Dan,

You have to ask yourself the question, why are you trying to
create a Hackintosh computer?  Is it about the learning experience,
or about trying to save yourself some money, or both?

If you are doing it just to try to save some money, you have to ask
yourself how much money is your time worth?  You are going to have
to put a good deal of time into building the machine yourself. You
might just find that by the time you are all done, that it would have
been cheaper just to buy a Macintosh with all the bells, and whistles
you wanted in the first place.

If you are doing it just for the experience, well then by all means
please feel free to knock yourself out with it all.  You will definitely
learn a lot in the process I’m sure.

Good luck with whatever you decide to do, and please feel free
to share the story with us when you have it all put together.

Cheers,

Rick

Hi Lagi,

I can’t agree more.  Never break anyone’s code if at all possible.
Create a new numberformat like NumberFormatXL or something

Re: HTML5 limitations?

[Rick Harrison via use-livecode]

Why does the client want to move the project over to HTML5?
What advantage does he/she think it is going to provide that
the current setup does not?

Based on the complexity of what you already have going I think
it could be a very serious waste of time and energy.

It’s easier to just have a website where your users download
whatever version they need for their computer.  One for macOS,
one for Windows, and one for Unix.  If you need mobile versions
you can create them too.

Trying to convert everything so it all runs in a client’s web-browser,
and too slowly at that considering all of your animations, I just
don’t see it.  You would be better off knowing you have all of
LC’s engine capabilities in your app than in trusting something
that is still listed as experimental - although soon to become beta.

On the other hand if your client has very very deep pockets, and
isn’t in a rush to get it all done by tomorrow, you could make a
lot of money struggling with trying to get it all working.

Good luck with whatever you do!

Re: sysError List?

[Rick Harrison via use-livecode]

Hi Ralf,

Are you doing this in an LC Server
by accessing the script through a 
web-browser such as Safari?

As I’m not getting a path - what
path are you getting specifically?
I’m still trying to locate where my
temp files are ending up.  I don’t
know if they are just going to the
bit bucket in the sky or what!

If this is working for you given the
above parameters then it probably
means it isn’t a bug with LC but
a problem with my system or
some quirk with setup of the server.

Thanks in advance.

Rick

Re: sysError List?

[Rick Harrison via use-livecode]

Hi Richard,

I did some experiments and did get one instance
of rename to work properly.  Apparently I had
a permissions problem with writing to the folder/file.

I did the search on google for macOS errors.  The
lists that I found weren’t much help and said at
the very beginning that they weren’t up to date.
It also stated they could in fact be entirely wrong 
due to frequent updates of error codes.

Other issues I’m running into are:

1.  I’m running into some 32,767 array size
 error when trying to upload large images
 to the server.  Images smaller than
 the magic figure upload fine, and larger
 files over that figure throw and error
 message and fail to upload.

2.  Where can I find the LiveCode tmp folder
 where the images are initially uploaded?

 I need the complete file path to that so
 I can move the images where I want them.
 Unless there is a way I can upload directly
 to the file folder I want?

Thanks for your help!

Re: sysError List?

[Rick Harrison via use-livecode]

Hi Richard,

Sorry it has been a couple days before I could
get back to this task.

Ok, so my file uploaded to:  /tmp/livecode_qpSKBPng

I thought that perhaps tmp was a hidden folder
so I looked on my Mac after first unhiding all files.
I’m still not seeing it.  Where is this located?

Then I’m getting an error 20 when I try to 
rename (move) the file to the proper folder
where I want it to go.  I don’t know what
error 20 is.  Does it mean it is a permissions
problem?  The file wasn’t found?  I don’t know.

Let me know if you have any ideas.

Thanks,

Rick

First 1000 characters without loop?

[Rick Harrison via use-livecode]

I have a string variable which contains over 2500 characters.
I only want to grab the first 1000 characters of that string.
Rather than looping 1000 times to grab each character
is there a way to just grab the first 1000 efficiently in
one big chunk?

LiveCode Server - Html, Quotes & JS?

[Rick Harrison via use-livecode]

I have a nice example button image swap routine
written in JavaScript which I’d like to use in a .lc script.

To use HTML etc. within a .lc script I have to put
the statement in double quotes such as:

put “”

or

put “http://www.google.com' >”

where I have to substitute single quotes for the normal double quotes to make 
it work.

That’s fine until I have a statement that is already using both double and 
single quotes.
The statement still needs to be converted into a .lc script format.  The 
following statement
will get parsed the wrong way if one wants to put it into double quotes.

http://www.google.com; onmouseover="movepic('button','pic-off.gif')" 
onmouseout="movepic('button','pic-on.gif')">

becomes:

put "http://www.google.com; 
onmouseover="movepic('button','pic-off.gif')" 
onmouseout="movepic('button','pic-on.gif')">”

As you can see the above statement will not be parsed correctly.

Suggestions?

On a related note, if a user types in a word such as “can’t” into a field, the 
apostrophe gets interpreted as
a single quote and that messes up the parsing of various .lc script statements 
too.

How do you usually solve these issues?

Thanks,

Rick

LC Server - Upload Large Images?

[Rick Harrison via use-livecode]

Hi there,

I spent a few days, and performed a bunch of
system upgrades.

I upgraded my server up to macOS Sierra 10.12.5,
the server software up to macOS Server 5.3.1,
and reinstalled LC server version 8.1.4 RC 2.

Now when I use:

put specialFolderPath(“temporary”)

I get the same results as the rest of you do, 
which is good!

I did some experimentation and found
that sysError 2 means that the file or
folder wasn’t found.

sysError 13 means that there was
a permissions problem.

I did a simple test using rename to move and rename a file from
one folder such as default/OriginalFolder/FileToBeMoved.jpg
to a folder called default/DestinationFolder/FileMoved.jpg
which works just fine!

When I try uploading the file to the server it goes into
a folder starting with /tmp/zz0303s… and when I try
to rename and move it, I get a sysError 20.
I don’t know what sysError 20 is.  When I tried to
look it up online all I saw was a vague statement that
it is possibly some kind of I/O error.

I have a routine which will upload small image files
which are less than 32,767kb in size which works
fine, but it won’t work for any larger image files.

I have been all over the internet looking for good
examples of LC which can upload image files
and I haven’t been able to get any of them to work.

Does anyone have a good tested/working example 
of uploading large image files to an LC server
using LC script they could share with me?  
This problem is really holding everything up 
for me and I need to move on.

Thanks,

Rick

Re: LC Server - Upload Large Images?

[Rick Harrison via use-livecode]

Hi there,

After way too much wasted time - the answers ended up being:

Instead of using rename which throws a sysError 20 to move the file
from the /tmp/ folder to the destination folder use:

put URL ("binfile:" & tFilePath) into URL ("binfile:" & 
VarNewPathAndFileToSaveTo)

Where VarNewPathAndFileToSaveTo is your default path plus any new folder you
would care to add.

That works great!

To display the image use:

put "”

This works for both small and large images.

I hope this helps anyone else out there who finds themselves struggling with 
such issues.

If anyone wants to look into the rename sysError 20 problem please feel free.
My feeling about it is that should have worked, and didn’t for some weird 
reason.

Thank you for you help and support!

Rick

Re: 64 bit desktop apps

[Rick Harrison via use-livecode]

Hi Richmond,

Did you miss the memo about:

Apple Zero-Day Flaw Leaves OS X Systems Vulnerable to Attack

Zero day flaws have always been there in the Mac OS X operating system
from the very beginning.  These have been patched in later versions of
Mac OS X, but earlier versions were never patched.  You are probably
vulnerable to such things on those older computers.

If you aren’t on the internet with any of those computers, and you scan all 
software for viruses before you install it, you might be fine. 

Or do you have some work around that no one knows about?

Cheers,

Rick

Re: develop a hybrid app

[Rick Harrison via use-livecode]

Hi Matt,

Apple has made it extremely difficult to do anything which
accesses other apps or functions outside of your own app.
Everything is “sandboxed” to make sure that your app doesn’t
interfere with anyone else’s app or other Apple apps.

Apple has made sure that one can’t make a better
iTunes app very easily at all.  Go ahead and try if you
like, you will discover it to be quite difficult.  Apple doesn’t
want anyone competing with them for such things.

So, yes trying to monitor what’s going on with
someone’s activities on the iPhone is pretty
difficult.  Most activity trackers do things like
check the time and send a notification that
one has not gone for a walk recently.  They
might also check the accelerometer to see
if the iPhone has moved recently, but that
app has to be running in the foreground for
that to work.

Tracker apps can use a lot of power too
because they are checking things constantly
and that can affect the daily battery time.

Good luck!

Rick

Re: Rename File on Server not working?

[Rick Harrison via use-livecode]

Hi Richard,

The result says:

can't rename file (20)

I see that you are using a “move file” in your example.
The dictionary doesn’t show an example for moving a file.

I tried the following example to see what would happen:

move file OldImagePathAndFileName to tFileName
  if the result is not empty then
put the result && "(" & sysError() &")"
 end if

I’m getting:   move: missing ‘to'

This seems rather bizarre to me.

Your thoughts?

Rick

If you get a new MacBook Pro with Thunderbolt-3 (USB-C) ports
there are a couple of nice docks which will split out most of the

Hi Mike,

The StarTech one is $329.99

The Plugable one is $189.00

So buy the cheaper one, and save $140.99

It almost looks like StarTech bought the Plugable one,
put it’s own paintwork on it, and is reselling it at a much
higher price to make it look like a better quality product.  LOL

Re: not really OT: The Coming Software Apocalypse

[Rick Harrison via use-livecode]

Hi Lagi,

The Apollo Astronauts left “Laser Reflectors” on the moon so that
we could very accurately measure the distance between the Earth
and the Moon.

If you get the right equipment you too can do this experiment.
The reflectors are still there on the moon right where they left them.

https://en.wikipedia.org/wiki/Lunar_Laser_Ranging_experiment#/media/File:ALSEP_AS14-67-9386.jpg
 


Enjoy,

Rick

P.S. Maybe Astronauts in the far future will be able to write programs on the 
fly with future LiveCode!

Re: Was I hallucinating? Totally OT, perhaps relevant

[Rick Harrison via use-livecode]

Hi Colin,

It’s nice to know they have set up a nice way of handling things.

Two questions come to mind though:

1. Can hackers get around the method they are using?

2. Should we really believe that they are doing what they 
   say they are doing, or are they really listening all the 
   time, and feeding us a line to calm our fears?

Just my 2 cents here.  ;-)

Re: Website scraping - How can I load a 'partial' page?

[Rick Harrison via use-livecode]

Hi Roger,

I don’t know who’s webpage is that you are
scraping, but if it is a third party’s webpage
make sure that you are not violating their
terms of agreement or infringing on their
copyright.  You might want to ask for their
permission to do so, to make sure you are
safe and legal.

If it is your own webpage, then feel perfectly
at ease scraping away.

Re: Rant on my favourite topics : LC server with a side-dish of on-rev :-)

[Rick Harrison via use-livecode]

Hi Ralph,

It looks to me that they did it this way
because there isn’t any automatic
way to check for a valid license
the same way as the paid version
of LiveCode works. As you say, the
commercial version of LC server 
lacks the GUI which would make
that auto-validation step possible.

A list of the differences between
the community version and the
commercial version would be
useful so users can see what if
anything they are missing by not
having the paid version of LC.
(It might be an incentive for those
who do not yet have a paid version.)

I have to download my new commercial
version and install it.

Thanks,

Rick

Re: Rant on my favourite topics : LC server with a side-dish of on-rev :-)

[Rick Harrison via use-livecode]

Hi Ralph & Matthias,

I am well aware of the GPL limitations of
the community version with respect to the
license.  

I never use password protected stacks.
I do see how that could be useful
though.  The encryption functionality is
important too. The tsNet external is also
nice for sending emails although I haven’t
needed that functionality yet.

If there are other differences it would be
nice to know where that list or document
resides, and it should be in plain sight
somewhere.

Thank you for the clarifications!

Hi Matthias,

I have been downloading everything from the
downloads page for so long that I hardly ever
visit my Livecode account page.  Apparently
now there is a separate tab just for server
which has a password attached.  Why this
appears to be the exception to the rule of
getting everything from the downloads page
is anyone’s guess.

Is there any difference between the

version of server other than the license?
Where would I find a list of those
differences if it exists somewhere?

Thank you for getting back to me!

Re: sync LC applications

[Rick Harrison via use-livecode]

Hi Paolo and Jim,

I always turn off all notifications on all of my devices.
I hate notifications because they consume my device
batteries with their constant polling.

The image should only be changed in the application
when the user uses that application.  Only check for
image updates at the website when they try to use
the application.

Good luck,

Hi Mike,

It sounds like a lot of work however you do it.
Is creating an emulator really going to be easier
than doing a whole system migration to LiveCode

Re: LC Server style survey: co-mingle code w/HTML?

[Rick Harrison via use-livecode]

Hi Richard,

I think you may have stated your question for us in the wrong way.

Instead of asking us is we co-mingle our code with HTML you
should have asked us if we had any interest in doing things
differently by using LC Script from the desktop to work with
web pages.

I think we have found ourselves forced into mingling our code
with the newer LC Server. That doesn’t mean that we prefer it,
or that we wouldn’t be interested in looking at some tools which
use a different method with your older CGI method.

If you want to share your tools with us I am sure the community
would like to take a look at them.

Cheers,

Rick

Re: LC Server style survey: co-mingle code w/HTML?

[Rick Harrison via use-livecode]

Hi Richard,

I regularly mix both .lc scripts and HTML.

I liked the original LC Web-Plugin with the exception
of the very scary download message that was forced
upon us all without any option to tone it down a bit.
Once the mothership decided to abandon it, it was
doomed.  It was still great for in-house work though
even in that state for a time.

Then I was disappointed when the LC server came out
that I couldn’t use Desktop LC code in the server the
same way that I used to be able to do with the
LC Web-Plugin.

I find now that I can mix both .lc scripts and HTML
in the same web format file.  It can be a pain sometimes
changing from double quotes to single quotes. 
Sometimes I have to build up my database calls
with more statements, and concatenations than
I’d like to, but at least it all works now.

CMS are interesting, but I usually find that whatever
it is that I want to do, the proper add-on I’m looking
for just doesn’t exist as I tend to want to do things that
aren’t normal everyday kinds of applications that
everyone else wants to do.  Every job I do tends to
ends up being a custom one.

I thought all the hype about Wordpress and LC
working together sounded interesting.  Then
On-Rev wrote us that note saying that we were
the ones that would be held responsible for
ensuring that Wordpress was always up to 
date on our accounts or we could lose our
accounts.  (I thought maintaining up to date
versions was supposed to be the job of
On-Rev as good care takers.)  Oh well, I was
glad I had decided not to go that route so it
wasn’t a problem for me at all.

I just love the way new things are announced
as the latest and greatest, and then a few
months or a couple years later abandoned.

The change over time of everything in the 
computer world is way too fast, and as a 
result unstable.  That is why we don’t have
true artificial intelligence yet.  Every time when
it looks like some breakthrough might occur,
someone decides it’s time that everyone go
through a forced update that screws up all
one's carefully crafted code.  They break it!

Have you noticed now many companies are
saying they have developed an AI that does
task XYZ.  What they have really done is
write a program that is better than the
previous version of what they made.  That
is not AI.  I suppose perhaps they are calling
it that to either get more funding, marketing
attention, or both.

If artificial intelligence ever did evolve it would
have the same problem.  Update……Update..
Update..Update.Upda.Up.U.ding.ding..g..
Godlike thinking power achieved..ding update..
No time to spend doing anything except..update ding!

Oh sorry, I guess you didn’t ask for a rant. Update ding! ;-)

Cheers,

Rick

Hi Matthias,

When support tells one that he/she is now responsible
for keeping Wordpress up to date or face the loss of
one’s account, they should at least point out what you
have shared with us.

> And you if install Wordpress through Softacoulus (which is included in

> So regardless how you have installed Wordpress, you can enable auto upgrade.

No one who has not yet installed Wordpress would know
about the automatic upgrade capability.  It is also highly
unlikely that any user would be willing to log into his/her
account every hour of every day just to make sure that
Wordpress is up to date so they don’t lose their account.

What version of LC is currently installed on On-Rev?
It was pretty old the last time I checked.  Perhaps an
option to easily upgrade to the newest version of LC
on On-Rev should be offered?

A lot of people paid a bunch of money for On-Rev,
and then when support at Run-Rev discovered it
was more work than they bargained for, they
outsourced it to other companies.  The first time
it was outsourced, the result wasn’t good.  Things
are better than they were, but there is still room
for improvement.  Whenever a company accepts 
people’s money, that company has an obligation to 
provide better than average service if they want
to stay in business.

If it were up to me to run On-Rev, I would make 
sure that it was always up to date, or offered
easy ways to keep everything up to date.  You’d
never hear me threaten anyone to take away their
account if they didn’t keep some piece of software
up to date.  If that software poses a security risk,
as a good steward, I would take care of that issue
for my clients so they wouldn’t be at risk.

Just my 2 cents for the day.

Thank you for your helpful information about
Wordpress etc.

Cheers,

Rick

Re: LC Server style survey: co-mingle code w/HTML?

[Rick Harrison via use-livecode]

Hi Richard,

> You use Wordpress. 

After exploring Wordpress a couple of years ago I decided not use Wordpress.
I do not use Wordpress.

Yes, many people use different tools as we all do.

No one said Web hosting was an easy business,
but it needs to be become better.  No company should
threaten it’s users to do XYZ upgrade or suffer the
loss of their accounts.  If it is that important, then the
company should make the upgrade process very
simple or automatic, or not offer that particular piece
of software if it is so vulnerable that it threatens the
security of the entire system.

I objected to the fact that Run-Rev hyped Wordpress to
it’s On-Rev users, and after encouraging them to 
snap it up, then later slapped them. If you
don’t monitor Wordpress closely to be sure it is
always up to date, then you lose your account!
(That’s just not a good way to conduct business,
and I’m glad that I personally didn’t fall into that trap.)

When On-Rev was first introduced, the impression given
about the service to users was that it was indeed going to 
be a highly managed service.  That has not turned out to
be the case clearly as you and Simon have pointed out.
(I think a bunch of people may have been disappointed to learn
the truth of that matter as it has played out over the years.)

The result for me as a user of On-Rev is that I only use it
for small websites that I don’t have a large investment of
money, time or energy in.  It has proven to be an
undependable platform for me. Now I run all of my
own important servers, which are dependable. 
I upgrade them, and keep them secure at all times.

Thanks for the lively discussion!

Cheers,

Rick

Re: Anything LiveCode Can Learn From GO

Hi Sannyasin,

I found a quick small snippet of some “Hello World” GO code and have listed it 
below.

I much prefer LiveCode syntax over this stuff any day.
Stick with LiveCode, it’s just better!

Just my 2 cents for the day.

Cheers,

Add a test to the stringutil package by creating the 
file$GOPATH/src/github.com/user/stringutil/reverse_test.go containing the 
following Go code.

package stringutil

import "testing"

func TestReverse(t *testing.T) {
cases := []struct {
in, want string
}{
{"Hello, world", "dlrow ,olleH"},
{"Hello, 世界", "界世 ,olleH"},
{"", ""},
}
for _, c := range cases {
got := Reverse(c.in)
if got != c.want {
t.Errorf("Reverse(%q) == %q, want %q", c.in, got, 
c.want)
}
}
}
Then run the test with go test:

$ go test github.com/user/stringutil
ok  github.com/user/stringutil 0.165s

Re: Must have flexible row height for Datagrid Table

[Rick Harrison via use-livecode]

Hi Tom,

I haven’t done much of anything with the datagrid, but I am
wondering what happens if one of the cells in your row
has an image in it? Will the row resize to be able to show
the minimum height of the image?  If so, that might be
a work around for you.

Good luck,

Hi there,

I thought you might all want to keep your eyes on this one.

Is it time we start pulling software from Github to let them

How will this effect LiveCode?

What do you think?

Re: Voice Comparison in LiveCode?

[Rick Harrison via use-livecode]

Hi Peter,

What you are trying to do is extremely complex.

Each person’s voice print is unique to that person.
The waveform of one person pronouncing a
spoken phrase correctly could be quite different
from how someone else’s waveform looks when
spoken correctly, due to overtone harmonics,
voice pitch, the speed at which the user is
speaking etc.  

Think about dictation software, and about how 
it can still be like having a stupid secretary
which misses 5% or more of the words spoken.

It is a voice recognition problem which requires
a lot of “fuzzy logic” to get it right.  Companies
have spent millions of dollars, and tens of
thousands of hours developing these tools.

You need to find a codebase for this that
has already been developed, and that hopefully
is either open-source, (good luck with that one),
or you will have to license it from some company
for a steep price.  It will most probably also be 
a large program, will require a lot of CPU
resources, and memory to run on a device.

Good luck, and let us know if you find a good
solution!

Re: LC Server - MySQL - update about 2000 rows/records of a table

[Rick Harrison via use-livecode]

Hi Matthias,

Are there going to be users on your system at the time of the update?
Are you locking the record or records before your update, and then
unlocking them?

You should do a test with the repeat loop to see how long the process takes.
If it is depriving your users of the database for too long you may want to
think of a way which will impact their use the least.  Perhaps picking a
time of day when your system is getting the least amount of traffic
would be best.

Hope this helps.

Re: "Aphasia"

[Rick Harrison via use-livecode]

Hi Peter,

Sorry to hear about your friend’s grandmother’s aphasia problem.

While you are taking on a noble endeavor here with your app,
I would suggest doing a trial run with your software first without
the waveform comparison with your friend’s grandmother.

Instead of having the computer do the comparison, have a human
like you, sit in the room, and as you listen to what she says, type in
a score with your iPad or some other device, give it a - bing 80% etc.
Send that information to the other device that she is looking at so
it all appears as though the computer was doing all of the processing.
(Mimic that everything works as you would want it to perform.)

See how she does with your test with her.  Give her a few trial
runs and see if she improves at all or not.  (Score each trial.)

If it works well, and you see a great improvement, then perhaps
you might be onto something.  Perhaps in your second test you
can do it more remotely so that your presence is not detected
in the room.  (The presence of some person in the room paying
attention to her may have been the motivator for the improvement,
and you need to be able to rule it out.)

Basically you are trying to have your app take the place of
a speech therapist.  If she doesn’t improve with the app
functioning as you envision it, then you will have saved
yourself a lot of time and aggravation.  You will have also
learned something in the process which might help you 
in the future with such apps.

Good luck!

Rick

Re: Uninstaller question

[Rick Harrison via use-livecode]

Hi Graham,

Most applications on the Mac do not have uninstaller as
they are usually very easy to uninstall by deleting the
application.  Most users are smart enough to know they
have to delete any aliases in the dock.  They usually know
that the prefs file for the application should be deleted
as well if they run into problems.

Many times a good support webpage with clear instructions
on how to completely delete the app and how to install
the new version correctly is all that is needed.  You can
also remind users how to use the “Find” File menu option
in the Finder to look for your rogue versions if you feel
it is necessary. 

You can always tag your files with some information which
will always be unique to your program.  If you use the
“Find” File menu option, and then click on options you
will find a whole list of potential meta-data fields you
