Re: Black boxes replace images in Mojave (Was "No subject")

[tbodine via use-livecode]

Mark and Matthias,

This workaround looks promising!

While I don't have Mojave to test against, I do find problem images have
many different colorSync profiles.

Matthias, after you have stripped out the profile, what does Preview's Info
screen show as the ColorSync Profile data?

I'm thinking it would be good to have an acceptable default value that I can
tell users is OK, and anything else should be stripped.

Thanks to your both!

Tom Bodine

Re: Black boxes replace images in Mojave (Was "No subject")

[tbodine via use-livecode]

Thanks for that info, Matthias.

Please clarify: 
Is the image you posted a screenshot of three separate png files or one
composite image? 
If separate, what are the differences between the files? (Strikes me as odd
that the black is only a part of the image. In my cases, users see entire
rectangles of black.)
Are the images in the screenshot being displayed in LC image controls or
through some other app?

Thanks,
Tom Bodine

Re: Large files crash on Windows 10

[tbodine via use-livecode]

Hi,

I develop a stack that is now up to 35 MBs on a Windows 10 machine without
any crashes like you described. I use LC 7.1.4 Indy for this. I also
distribute standalones built with this stack and it is also stable on
Windows 10.

When you have these crashes, do you find the artifact ~ file that indicates
the Save process was interrupted or has failed?  Does the stack file become
corrupted?

Re: Too fundamental to be a bug, so what's wrong?

[tbodine via use-livecode]

 Panos' test and Mark's insight have me on the right path.

I am not using "numberFormat" anywhere, but I am setting the value of
gTSsettings["teamcount] from a mouseup script on a scrollbar. Since my
scrollbar output is apparently coming out as a floating point value, I need
to add rounding to it.

Not sure how the scrollbar was able to generate floating point values, as
Start/End/Current values are all integers. Is "scroll distance on bar click"
actually used in the result calculation? That was set to .9ish.  I thought
the scroll distance setting was more of a UI setting that allowed the user
to not have to hit the exact tick on the scrollbar. 

Thanks to all for your help on this.

Hi,

The global is just gTSsettings, so I modified your command as...

global gTSsettings; put gTSsettings["teamcount"] - 4

RESULT:

-0.497436

No, strict compilation is off. 
Variable preservation is on.

So are LC 7 and 8 the same in terms of how variables are declared and
accessed? That's been my assumption.

Nope, not it. 

The global is declared at the top of a group script containing numerous
handlers that use that and other global vars.

(Unless there was a change from LC 7 to LC 8 that requires declaration of
variables in each handler? I am porting a LC 7 project into LC 8.)

Too fundamental to be a bug, so what's wrong?

[tbodine via use-livecode]

Hi all.
I have a global array containing the value 4. It's stored in
gTSsettings["teamcount"]
The bizarre thing is when I do value comparisons, gTSsettings["teamcount"]
does not equal 4.
This first occurred in a repeat loop, but I can reproduce it in the message
box, too.
put gTSsettings["teamcount"]4put gTSsettings["teamcount"] = 4false
This seems way to fundamental to be an undiscovered bug. So, what am I
missing?
I'm using LC 8.1.10 Build 14072 Indy on a MacBook Pro.
Thanks!

Re: Quit Command corrupts standalone (stack called by standalone splash)

[tbodine via use-livecode]

Hi Roland.

The "~" file is the original  (uncorrupted, unsaved) version of your stack
before LC executed your Save cmd. If you remove the "~" from the filename,
you'll probably find you can open that. LC creates the "~" file at the start
of the save operation and, if all goes well, removes that file when save is
complete. 

My guess is your problem is rooted in the lengthy save time in the quit
routine. Here are a couple ideas of how you could deal with that:

1) Do the save within a try/catch statement so you can deal with any error. 

2) If you are just saving some user data like prefs or fairly minor stuff,
then why not save that into a separate substack outside of your main
application stack? That should greatly shorten the time it takes to save. 

Hope that helps.

Tom Bodine

Exe and dll errors after standalone build

[tbodine via use-livecode]

Hi all.

I'm getting two error dialogs on launching a newly built standalone (built
with LC 7.1.4 on Win 10) of a stable project. 

Error on: Appname.exe 1 (6)
Error on: revsecurity.dll 1 (6)

I've been producing builds with this same project for many years without
seeing these errors. 
The errors are not triggering my errorDialog handler.
The errors happen whether or not I "Run as Admin."

Does anyone have a clue as to what the errors mean or possible causes?

Thanks,
Tom B.

Re: Anyone can confirm laggy IDE on Windows 10?

[tbodine via use-livecode]

On Win 10, I use LC 7.1.4 routinely and LC 8.1.x occasionally. In my
experience, LC v7 runs as smoothly as it did on Windows 7. But LC 8.x is
very hard to use with its slow script editor. Even dragging controls from
the palette to the card is spotty. 

Fortunately, my major project codebase is in LC 7.1.4.

My two cents,

Does "databases use transactions" mean DBs don't rewrite the entire file
when there is a Save operation, but only write the changes into the DB file?
(Hence, faster saves?)

Autosaving stacks corrupted on network drives

[tbodine via use-livecode]

Hi all.

Looking for your insights on an issue. Here's the scenario.. 

I have a standalone Win/Mac app that autosaves user data to a stack file as
the user moves from card to card. Typically, files reach sizes of 100-200k.
Normally, this works great. But a couple of times a year, some user will
manage to get corrupted data causing his stack files to be unusable. 

I've opened some of these corrupt stack files in a text editor and found the
data loss shows the Save operation was interrupted. There's no garble. Just
an abrupt end to the data and the file.  

I've found a common link in these cases -- either the app is on a network
drive or the stack file is on a network drive. 

My theory is that network save operations are slower than saving on a local
drive, and somehow this contributes to the data loss. But how?

All theories (except conspiracy) are welcome!

Thanks,
Tom B.

Re: AW: htaccess rewrite rule to https let my apps stop working

[tbodine via use-livecode]

T.

Had a similar experience while migrating my site to https. What I found was
my standalones were missing the revsecurity.dll external. After rebuilding
those to include revsecurity.dll, the standalones were able to contact my
site and access stacks and other files there without changing my links from
http to https, since the htaccess was managing that.

Notes: On Windows, that must be at the same level as the standalone exe
itself rather than the externals folder. And codesign your externals as well
as standalones.

HTH,

Hi Geoff,

You app worked for this same user in the past, but now does not... Did
Windows 10 break it, or did the user migrate to another machine?

Possible culprits could be the user's security software or IT policies that

Re: Changes to Msg Path from LC 7 to 8?

[tbodine via use-livecode]

Thanks for the encouragement, Richard. Looks like I'll be doing the "Humility
Workout" for quite some time.

For future list searchers who might have this same symptom, I found the
cause: One of my stack level scripts used "theme" as a parameter name, but
apparently that's a reserved term that is strictly enforced in LC 8.
Changing that allowed all my stack scripts to run normally.

Re: Changes to Msg Path from LC 7 to 8?

[tbodine via use-livecode]

Another clue... If I use the message box to call any simple stack level
handler, LC 8 changes that command to a put statement.

Example:

I type in msg box: zzShow -- a stack level handler
Msg box changes my cmd to "put zzShow" and then puts "zzShow" in the output
area.

find handler" error. (I confirmed that the defaultStack is my main stack.)
LC 7 had no problem with this.

Example:

Card script:
on preopencard
centerThisCard
end preopencard

Stack script:
on centerThisCard
-- do stuff
end centerThisCard

Any theories or insights on why LC 8 won't do this when LC 7 will?

Thanks,
Tom B.

Re: Suggestions for LiveCode (the company) to increase its revenue

[tbodine via use-livecode]

Code signing can be a major pain point. Adding code-signing features to
Livecode (or in a supplemental tool) could be a selling point for Indy and
Business license users. I pay about $50 annually for a third-party
code-signing tool subscription on the Mac platform. 

LiveCode Ltd may able be able to become a third-party Comodo certificate
reseller and make ongoing revenue by providing that service.

Re: Customer database stack for FastSpring, etc?

Thanks, Richard. What you described will certainly work for future customer

I thought someone might have created a customer contact tool in Livecode

Hi,

I tested your script on a Win10 Pro PC, primary screen size of 1920 x 1080,

Could it be your user has dual screens and the one the program opens on is

Re: UI design problem

Thanks Jim.

A right-click toggles the text field between being editable-text or a
movable block of text, but there are no resize handles on the text field.
The image, however, has resize handles.

When text and image overlap, I use the mousechar to figure out the user's
intent. (If the user clicked on  blank space, I treat that as an image click
and pass the click through to the image control to make it movable. If the
user clicked on headline text or the space between words, then the text
block becomes movable.)

I narrowed my original issue down to this: "grab" doesn't work for a
mousedown that is passed through to another object. So I bailed on "grab"
and I'm using the mouseStillDown message to make either the text or image
follow the mouse until released.

Spent way to much time on this!

Thanks to all for your suggestions.
Tom

"Pass mousedown" doesn't work here. (Message does not travel down to the
image control below the field.)
I used a send "mousedown" which does travel through, but what doesn't work
then is the "grab image 'blah'" line in the mousedown handler attached to
the image.  The same mousedown handler works fine to grab the image when I
click directly on the image control.

UI design problem

[tbodine via use-livecode]

Hi Livecoders.

I am hoping you'll have some ideas for solving a UI design/coding problem.
My app lets users create simple presentation screens, one per card. The user
can import a picture and add a headline (text field) to the card.  And since
the user will sometimes want the text to be over the image, the text field
is always the top layer.

The problem is the text field often blocks the user from grabbing and moving
the image control below. (Both the field and image are meant to be movable.)

My many attempts to solve this have wandered into "rat's nest" territory, so
I'm hoping some of you will know a simple way to pass a mousedown from a
text field to an image control.

Thanks!
Tom B.

Looks like we'd have to request user to disable or ignore both AV SW and

Idea about Norton

[tbodine via use-livecode]

Hi Graham.

I wanted to float a rough idea off-list... Tell me what you think.

If Norton faults our files for being new and not (yet) popular,  perhaps we 
could generate a base of download activity ourselves to get over the threshold. 
Specifically, I'm thinking of an informal group of software authors who form a 
"mutual download society." 

Say we had 10 authors to start who agreed to download one another's product 
file(s) once a day for a month.  At worst, we'd probably learn some things 
about what Norton counts, what it ignores, and what is the threshold to move to 
a trusted level. At best, we might help each other to win acceptance.

For those of us with fast, unmetered connections, there's virtually no cost to 
the downloading of files other than the time it takes to do it. And with 
Livecode we could easily write a stack to automate that job.

Thoughts?

Tom Bodine

Re: AW: Boring but important - selling a download product for Windows

[tbodine via use-livecode]

Hi all.

Here's what I've learned from many years of providing PC downloads:

* Email attachments are heavily filtered and rightly so. Use this only as a
last resort for delivery of a program.
* These days, fewer people are willing to download a trial version, in part
due to Norton, but also many organizations' IT block all downloads. If you
provide both a good, fast demo video and a trial version download, then
users can choose what works and is comfortable for them.
* Once a person buys your product, she is much more committed to downloading
your product and will be less put off by obstacles. But expect to provide
some support or guidance.
* The big value of code signing is it's a mark of professionalism and
usually reduces OS suspicion. I agree it is a slight that Norton treats
small developers and new releases as dubious. But, remember, Norton isn't on
all machines, so don't let Norton guide all your decisions.
* I use a traditional installer (Innosetup) because it looks professional,
ensures the app is installed with admin rights and into the right location,
displays a license and readme doc, creates desktop shortcut to the app, and
includes an uninstaller (also code signed). 
* For download links, avoid redirects and use an https or other secure
connection method to link to your download files. It helps establish trust
if your download file is on the same domain as your site.
* Fifteen years ago, download sites were useful. Today, they compete with
your site for search engine visibility and sometimes repackage your app with
their own installers that add adware or malware. Avoid!

Hope that helps.
Tom Bodine

Re: How do I codesign an App?

[tbodine]

It is VERY frustrating, though I was able to get codesigning to work earlier
this year using AppWrapper 3. 

But even with successful signing, Apple manages to rub salt into the wound
with this bug If you codesign for Mac as a third party developer for
distribution outside of the app store, then people installing it may still
get a message that says "can't be opened because it is from an unidentified
developer". Unidentified? WTF!

There is a simple workaround for downloaders willing to stick with it. What
I did was document the workaround in a pdf and put that right next to my Mac
download link. Here it is:
https://www.gameshowpresenter.com/MacOpenError.pdf

I don't know if the latest MacOS has fixed this bug or not. I assume it's a
bug, but it feel like a punishment for those who venture outside the walled
garden.

LC performance change from Win 7 to Win 10

[tbodine]

Hi All.

Has anyone else experienced a severe drop in LiveCode's speed in Windows 10
compared to Windows 7? 

I recently upgraded to Win10 on my PC workstation. When I use LC 7.1.1 (my
mainstay version on this machine for a long time now), it's like it is stuck
in a bog. Specifically:
* A standalone build that used to take under 2 minutes now takes more than
10 minutes. (It appears the "Removing development properties..." part of the
job is the main slowdown, consuming 8 minutes.)
* When my code calls uses the Answer cmd, the title "Answer Dlog" appears in
the window for about 1 second before the my actual text is displayed in the
answer window.
* The script editor's responsiveness is awful. Keystrokes don't buffer.
Arrow key actions can result in undesired repetitions. 

Anyone else experiencing this? Suggestions? Under Win10, all the
productivity benefits of using LC have vanished!

Thanks,
Tom Bodine

Re: Unidentified Developer

[tbodine]

Hi,

My understanding is this second-class treatment is what Apple does to us for
opting out of their app stores.

You would think after all the trouble we face to maintain Apple's
code-signing system and play by Apple's shifting rules, that our code-signed
apps would at least have our valid IDs recognized. But, no. Our users are
shown the "Unidentified Developer" warning, which creates suspicion and
complications. I don't know if Apple sees this as a punitive strategy or
just a bug, but I see it as an offense.

My two cents.

Hi Jim.

Nice script! 

I am exploring a project that would have a similar need to embed images in
fields, so I have a couple of questions for you...

1) What method are you using to embed those images in your field? 

2) For smaller images, are you able to inset them within the text and have
text wrap around, such as a small picture inset at the start of a paragraph?
(I've been able to place the image at the start, but not able to get the
paragraph of text to wrap it.)

Thanks,

Re: Playing movies

[tbodine]

Hi, Bill.

Seems the whole LC community is in a state of frustration regarding this. 

But one minimal method I find works to play an online movie is to embed a
movie url in a LC field with the linkStyle set to "link". 

Then add to your stack a script...

on linkClicked pLink
 launch url pLink
end linkClicked

(Fine print: linkClicked does not work except in Browse mode, the field must
be locked and it must have its listBehavior property set to false.)

I don't know of a way to find out from the browser when the movie has
finished, so I wait for the resumeStack message to fire indicating the user
has returned and, presumably, the movie is done.

If you prefer an icon to a text link, perhaps you can embed a graphic in the
field and link from that. (I haven't tried that, but you get extra credit if
you make it work!)

HTH,
Tom B.

Modifying revErrorReport

[tbodine]

Hi All.

Last year, I modified revErrorReport in LC 6.5.1 in order to add more
environment data (platform, version #, etc) to users' emailed Bug Reports.
That worked well.

Now that I'm working in LC 7.1.1, I need to repeat those modifications to
revErrorReport*. But upon saving the edited stack, I get an error: 
"Can't save stack revErrorReport due to an error: Can't open stack backup
file  Check the file path, and make sure you have sufficient permissions."

I have enabled all permissions (working on Win 7), but the save error
persists.  Anyone know what "stack backup file" this refers to or have any
other ideas about this?

Thanks,
Tom

Re: Windows 10 file paths

[tbodine]

Followup on the code signing hunch:

We know in the Apple world a lack of code signing can get an app banished by
Apple's Gatekeeper. So perhaps a Windows machine with high security
requirements also blocks exes or dlls that are not signed. 

It looks to me like RunRev does not code sign the dlls used for Windows
standalone builds. In a spot check of the externals in my LC 7.1.1
commercial installation on Windows 7, I see several external dlls there are
not code signed by RunRev. (I did not check them all.) Dlls in my
standalones are also not signed until I do that myself.

Innosetup has the capability of calling your code signing tool and signing
the dlls and executable as part of its installer compiling process. Using
that, my dlls get code signed painlessly.

Re: Livecode Licence Rules for dummies ....

[tbodine]

Hi,

You didn't mention how you are distributing your programs or what platforms
your users have. My understanding is if you build standalones from your
licensed version those standalones can be distributed at no further cost to
you. At least those were the terms I recall from the 5.x era. (I know the
more recent "Indy license" put some limits on that scenario.)

If you want to distribute your stacks directly, your users will need to get
some version of LC to use your stacks. 

If you are making standalones for Mac users, you may find that 5.x doesn't
work on newer Mac OS versions due to Apple's continual changes. So,
Mac-wise, 5.x could be a dead end. Have you considered using the Community
Edition for your projects?

Re: play vc xyz, still stuck in the 80s?

As a multimedia developer, I just want to echo what Klaus said about the lack
of modern multimedia support in Livecode.  Fixing this shortcoming will lead
to more new customers for LC. I know that I, for one, have not been able to
recommend Livecode to my peers due to this lack of modern multimedia
support. I bet I'm not the only one. 

My 2 cents.

Re: [ANN] lcStackBrowser v2.2.1

As a user of lcStackBrowser, just want to say this latest release has
completely replaced my need for the LC Project Browser. I was experiencing
chronic crashes with LC's Project Browser. Those went away with
lcStackBrowser. And it has reduced screen clutter from the IDE by gathering
so much functionality into one window.

Re: Application Data

[tbodine]

There's one potential problem with cloning or copying a group or controls
from one stack to another... In a standalone that uses password protection,
the engine will silently block the copy/clone operation as part of that
protection. (In the IDE, everything works fine. It's only shows up as a
problem when you build a protected standalone.)

So when using stacks as user files in a protected app, I've found these two
things are necessary: 
1) make those user file stacks unprotected.  
2) any controls or groups being copied into the user stacks needs to
originate from stacks (or substacks) that are also not protected.

Hope that's useful.

Re: uncrufting a stack file?

[tbodine]

Hi,

Not sure of your platform or LC version, but perhaps this is relevant: I
went through a period of chronic crashes while saving work on a large
project that originated two years ago in LC 5.5 and is now in LC 7.1. The
crashes were happening on Win 7, LC 7.x (pre 7.1). What helped reduce, but
not eliminate, the crashes was to reinstall LC and to thin out my active
plug-ins.

I still get some crashes, but rarely when saving. Most of my crashes seem to
involve the Project Browser or copy/cut/paste actions. Another crash inducer
for me is to put the script editor window on a second screen while the main
IDE is on the first screen.

Again, all that was on Windows (7) in LC 7.x.

HTH,
Tom

Re: How can I get a high-res image into LC?

[tbodine]

There is still no import feature of SVG vector graphics. (And the EPS import
is very limited and old.)

The "Roadmap" says: "Vector Shape Object Use widget framework to write this
control."  So, like the multimedia player object, SVG is in LC8 limbo. Note
that the bare info. in the roadmap blurb does not specify import, export or
even SVG. So it's hard to know what to expect, though the LC8 DP has some
clues. 

If you are up for an adventure, I believe the LC8 DP has a widget into which
you can paste the SVG path information of a drawing, if you can get a hold
of that data. LC8 also has a widget with the vectorized FontAwesome icon
font, which enables you to easily make scalable button graphics. But all
that is over the LC8 horizon unless you are willing to make your project
with a developer's preview version.

Maybe the Global Jam will result in LC8 shipping soon. Hope so. 

Tom

Re: Future crowdsourced features and priorities

[tbodine]

Yes, multimedia is Livecode's great weakness. Upgrading LC's multimedia to
modern times was among the stretch goals in the original Kickstarter
campaign and many of us are awaiting that. Since it was promised and paid
for as part of that campaign 2.5 years ago, I don't see how they can come
back to us for funding that particular feature. 

Because modern, reliable multimedia support is more important to my business
than any of the "future features", I'm holding back further investment in
the LC platform until the multimedia stretch goal is delivered. 

I believe LiveCode Ltd. could boost its licensing revenue and reputation by
creating outstanding multimedia support. As it is now, the lack of modern
multimedia support is a deal killer for some potential buyers. 

I look forward to a day when I can be more enthusiastic about LiveCode and
support its "future features", but not until "past promises" are delivered. 

My two cents.
Tom Bodine

Re: Audio Delivery to Multiple Platforms

[tbodine]

Hi,

This approach is working to play mp3s in a LC 7.0.5 standalone on Windows 7
and Vista:

I've tested this on a Windows 7 machine where QT is installed, but I set the
dontuseQT to true. And on a Vista machine that does not have QT installed.
Worked on both.

on PlayMP3 theMP3file, pname
lock messages 
set the filename of player pname to theMP3file
unlock messages
set the currentTime of player pname to 0
start player pname 
end PlayMP3

And to stop the player:

stop player pname 

I don't know yet how well this holds up on versions of Windows other than 7
and Vista.

Hope that helps.

Re: Audio Delivery to Multiple Platforms

I searched this list and the LC forums to piece together a working method,
and the lock messages was part of what was recommended. 

As Paolo said, multimedia in LC is in a state of chaos. Personally, I'd
rather have stable, coherent multimedia controls before experimental things
like html5 export. 

It would be great if the mothership would provide a status update on
multimedia in a blog post or here.

Choosing a database and LC tools

[tbodine]

Hi,

I want to add a content library module to a LiveCode-built project. It will
enable users to store, tag, sort and retrieve their content. I've read
various threads and articles about databases, but I have minimal database
experience and I want to get it right the first time. So I'd appreciate
answers to these questions and any other insights: 

1) Is SQLite the best choice for local database file with a Livecode
interface? (Each database record will need to hold a few sentences of
Unicode text, 1 or 2 small arrays, the text contents of a few cprops, and a
field for tags the user can apply to categorize the various records.) I
doubt the number of records would ever exceed 10,000 with an average more
like 2,000.

2) The content of some records may have associated images or audio files. I
can store the paths to those, but paths break easily. How much does it bloat
or burden a database to store jpgs, pngs, wavs or aifs files in records?

3) I see there are a few 3rd-party tools for database work with Livecode.
(SQLyoga, SQLiteAdmin and SQLMagic). Are there others? Are these current
with LC7? 

4) Are there contract developers in the LC community that specialize in
setting up databases with LC interfaces? 

Thanks!
Tom B.

Improving Bug Reports feature of standalones

[tbodine]

Hi all.

I use the built-in Bug Reports feature of the standalone builder, which
provides basic info. via email when a user hits an error. Problem is these
reports omit basic, key details, such as the platform and my codebase
version number. And users never include those in their comments.

A typical bug report sends this info:
Executing at [timestamp]
Type: [ex.: Chunk: can't find stack]
Object: [ex.: a stack name]
Line Num: 366
Hint: [ex.: a handler name]
Comments: 

Is there a way to tweak the contents of the error report to add a product
version number and platform stored in a global? 

Thanks,
Tom

Re: Text to speech and create wav file

[tbodine]

Hi Bill.

I don't know if that's doable within Livecode. If not, perhaps you can use
an external source. A site such as http://www.fromtexttospeech.com/ may have
an API where you can send the text and get back a url to download your wav
file.

On the Mac side, looks like many people have used Applescript to save audio
files from texttospeech.
(https://discussions.apple.com/thread/2290534?tstart=0)

In the near future, perhaps LC builder will provide the OS connectons so we
can do this sort of thing within  LC.

Re: AW: How do you handle the poor performance of LC 7?

[tbodine]

 Currently everything I do in LiveCode is done in v7.0.5.
Do you get frequent crashes?


 That said.. 7.0.5 is frustrating. Crashed 5 times on me to today...

I am trying to move entirely to V7 engine, but as Brahmanathaswami notes,
7.0.5 is makes it very hard with frequent and unpredictable hard crashes.
(I'm on Win 7. Yes, crash report filed, but not for every crash because at
this rate that would become about half my work day.)

Is the instability of 7.0.5  just on the Windows side or are Mac users
seeing this, too?

It's hard to be optimistic when something that crashes as much as 7.0.5 is
labeled a release candidate. 

Thanks,
Tom Bodine

Re: AW: How do you handle the poor performance of LC 7?

[tbodine]

Thanks, Richard. Here are the basics:
* Platform Win 7, 64-bit machine
* Running LC 7.0.5 (rc2)
* Bug report of these crashes:
http://quality.runrev.com/show_bug.cgi?id=15418
* The application is a quiz application that lets the user to create quiz
content and customize its presentation. It's been in development starting
with LC 5.5 about two years ago. I moved it to v7 to make use of the Unicode
support, which has worked great. (The app has no database or network
functions.)

All crashes (so far) have been in the IDE, not in standalones. Crashes are
usually triggered just by using the IDE's menubar. For instance, sometimes
when several controls are selected and I want to align them, clicking the
menubar to access the alignment cmd will trigger a crash. (But not always.)
Other times, clicking menubar to access Save cmd will do it. Another crash
came from trying to select some output text from the message box.

 Have you found some activities that never crash, and others where the
 crashes occur?  

That's the maddening thing. Actions that works fine much of the time will
suddenly yield a crash. For instance, saving a stack in the the IDE from the
menubar. (Now I do all my saves from the keyboard shortcut.) So what all the
crashes have in common is an action involving use of the mouse.

Thanks for any insights on this.

Tom Bodine

Re: AW: How do you handle the poor performance of LC 7?

[tbodine]

Hi Richard. 

Thanks for your interest in this case.

Do you recall if these crashes occur more frequently if the Project
Browser is open? 

I virtually always have the project browser open!

I have turn off all 3rd-party plug-in tools in case those are a factor and
will see if there are any improvements.

Thanks,
Tom

Re: AW: How do you handle the poor performance of LC 7?

[tbodine]

Thanks Richard and Mike.

I will run without Project Browser and see how that goes.

Mike, good theory on drives, but not a factor here: this machine runs off
one SSD. No USB drives involved. I don't have data on the time factor, but
I'll start logging my sessions to look for a pattern.

When a hard crash occurs, do you kill whatever processes might be hung,
then immediately restart lc? Or do you restart the whole machine? I'd
recommend a total machine restart at least once then see if stability will
increase for a while.

I have done both... relaunch LC immediately and, other times, restart the
machine.

Thanks for the insights.

Tom

RE: Confirm bug in MeasureText in LC7.0.4 stable?

[tbodine]

Hi John.

It wouldn't be the first time the bug turned out to be in my brain. But does
it strike anyone else, based on the dictionary description, that this should
be reporting info. similar to the formattedHeight and formattedWidth?

Use the measureText function to find the dimensions of text drawn with the
effective font attributes of an object.
Parameters:
The text is any native string. For unicode strings use measureUnicodeText.
The object reference is an expression that evaluates to an object reference.
The mode is one of:
•   width - (default if not specified) - returns the width of the text
•   size - returns the width,height of the text

Thanks,
Tom

Confirm bug in MeasureText in LC7.0.4 stable?

[tbodine]

Hi,

Do you get this odd behavior of MeasureText function in LC 7.0.4 stable?
(I'm using Win 7).

Make a new field with don't wrap off. Add the following script to the
field and watch the message box. Reported vertical size never changes when
there are hard or soft line wraps. It's always the height of a single line.
Reported width seems to ignore line wraps too and reports as if don't wrap
is on.

on keydown
   put the text of me into testthis
   put measureText(testthis,me,size) into tsize
   put tsize  testthis
   pass keydown
end keydown

Thanks,
Tom Bodine

Re: struggling with player

[tbodine]

It would be really helpful if the LESSONS part of the Livecode site gave the
correct info for the player. 

Agreed! As a relative newcomer to LC, the two biggest obstacles I found to
learning it are out-of-date online lessons and the spotty indexing of the
Dictionary. Maybe when the dust settles from the LC 7/8 push there can be a
refresh of all that. It'll be needed with so much changed.

In the meantime, I'm very grateful for this list!

Re: Hanging indents?

[tbodine]

Terry,

If you are open to your hanging indent lines having an outline or list
format, try setting the ListStyle of the block of lines where you want the
hanging indent. Here's a tutorial:

Filtering text styles on the Clipboard

[tbodine]

LC friends,

I have an app with basic word processing and I'm looking for the best way to
detect the source of what's on the clipboard. I'm trying to apply two rules:
1) Text formatted within LC can be copy/pasted with styled text using
clipboardData[styledText]
2) Text formatted from outside of LC is pasted as plain text using
clipboardData[text] (so LC field formatting is automatically applied to
it.)

The reason for rule 2 is to filter out formatting by Word or other sources
that tends to cause issues.

My kludgy method is to identify any text copied within LC by doing a
comparison. When there's a copy/cut cmd in LC, it stores a copy of that
Styledtext in a global variable. When a paste cmd is given, the
clipboardData[StyledText] is compared to that variable. If it matches,
rule 1 applies, otherwise, rule 2.

I have this nagging feeling that there's a more direct way that I've
overlooked. Anybody know of one?

Thanks,
Tom Bodine
