Actually you can. Another thing that slows down a script is using a 
counter variable in a repeat loop. Sometimes you have to, but if 
possible use the "repeat for each" structure, which is much faster.


I didn't actually test this so you may need to adjust it, but this 
handler only hits the field to twice and avoids a counter. Using 
htmlText allows you to color the lines without accessing the field 
repeatedly. It should be fast enough that you don't need to have any 
visual progress indicators; using "repeat for each" can typically 
process thousands of lines in a few milliseconds.


on mouseUp
   put fld "All" into allEntries
   put fld "Rural" into ruralEntries
   set the itemDelimiter to tab
   repeat for each line tLine in allEntries
  put tLine into tCurLine

   set the htmlText of fld "All" to tNewList

select after the selectedText

[Richmond]

So, here I am with a large textField, and as I merrily type into it new 
characters keep getting

added to the end of the string (as one would expect):

Now, this is a textField being filled up with unicode (double-byte) 
chars, and to make sure the

next chars gets placed in the correct place my insertion routine ends with

select after the selectedText

HOWEVER, when my line of text gets near to the edge of my textField I 
tend to hit the RETURN

or ENTER button on my keyboard and start a new line . . .

after which things go "funny", and the  select after the selectedText 
keeps pushing my

text insertion point back to the end of line one of my text.

Obviously "this just won't do" . . . .

Richmond.

use of colors of an image?

[Tiemo Hollmann TB]

Hi,

I wonder what you can use the colors and patterns of an image for? I havn't
used them before and when I try to set one of the eight colors, either of an
empty image or an actual image, nothing is seen. I was hoping I can use them
as a kind of hilite color, or as a kind of a blend level of the image, but
so far I must miss something to use them.

 

What I would like to have is a "hilite blend level" as a kind of "hilite
icon" or "hilite color", with which I could show another state of the image,
when clicked. The only other way I see so far is to work with two different
images, which show the different state and scripting both images to switch,
or using a third "overlay graphic" with ink=noop (thanks Klaus!) to control
the switch of the images, when clicked. But perhaps there is a way to work
with only one image?

 

Thanks for any hint and have a nice WE

Tiemo

Re: How to sync multiple functions / routines in parallel

[Nonsanity]

So you have data in memory that is constantly being updated, and need to
save the data to several databases periodically. But when you save to each
database in sequence, the data could be updated in between them, causing the
databases to be out-of-sync.

So what you could do is snapshot the data in memory by making a copy of it,
then use the static copy to write to each database in turn. This keeps them
safe from the continuous updates.

Re: How to sync multiple functions / routines in parallel

[Bob Sneidar]

Lock all the databases first, then update them. I'm pretty sure all SQL 
databases have the ability to lock tables. In mySQL the sequel is:

LOCK TABLES
tbl_name [[AS] alias] lock_type
[, 
tbl_name [[AS] alias] lock_type
] ...

lock_type:
READ [LOCAL]
  | [LOW_PRIORITY] WRITE


UNLOCK TABLES

Now if anything goes wrong in between that causes an execution failure then 
that is obviously very bad. So you want to put your code  that updates the 
databases in a try/catch control structure, and in the catch, before any 
interaction with the user, unlock tables. I'm pretty sure if it's a disconnect 
problem, the SQL database will terminate the connection and drop all the locks 
you set automatically.

ANN: Live LiveCode Code Event #21

[Mark Schonewille]

Dear folks,

It is a big pleasure to announce the 21st edition of the Live LiveCode Code 
Event with two interesting presentations. This weekend's event is scheduled for 
30 April 2011 at 19:00h GMT (Sat. 22:00 in Moscow, Sat. 20:00 in Paris, Sat. 
14:00 in New York, Sat. 11:00 in Los Angeles, Sun. 04:00 in Sydney, Sun. 03:00 
in Tokyo, Sun. 2:00 in Beijing; check your local time here http://qery.us/oy).

Thierry will demonstrate one of his latest LiveCode externals called SunnYmidi. 
SunnYmidi is a fast and easy-to-use music midi player with absolutely no 
latency.

Chris is currently working on a project for iOS and will show how you can use 
scripts that help you make your projects, doing tasks that aren't built into 
the LiveCode IDE by default.

eHUG, http://www.ehug.info , will be raffling off the e-book "Take Control of 
Running Windows on a Mac" courtesy of TidBITS, http://www.tidbits.com/ .

During the event, Economy-x-Talk offers a 25% discount on their Installer 
Maker, which can be downloaded at http://installermaker.economy-x-talk.com . A 
discounted license can be obtained at http://livetalk.us/im .

Make sure to use ChatRev during the happening, otherwise you won't know where 
to watch the streams, which will be announced in ChatRev. Download ChatRev here:
http://bjoernke.com?target=chatrev
or enter in the message box:
go stack URL "http://bjoernke.com/chatrev/chatrev1.3b3.rev";

Yes, it was because I got an email from Chipp telling my that He and David

Re: Launch and the working directory

If I understand what you're asking:

  set the directory to "/Volumes/myapps/mystuff"

You can also use "defaultFolder" instead of "directory".

Alternatives to "answer"

[tbodine]

Hi LiveCoders.

I'm working on my first real LC project and now I've dug myself into my
first LC hole. Hoping for some advice...

I want to present user with a dialog box that is more attractive than the
standard "answer" command. (Bigger type, transparent, icon buttons). I tried
making a separate card in a separate stack that I could open over my
mainStack card, but that is creating lots of errors now with "can't find
card" messages when I use:

call processingHandler of card "Main" of stack "Top". 

Basically, I want a semitransparent dialog box with two buttons to open over
a mainStack card. The user's button choice needs to be returned to the
mainStack script and the dlog Card closed.

Any suggestions on how to do this?

Thanks!
Tom Bodine

Use the dialogData. You can set it to whatever you want in the "dialog" stack, 
and then retrieve it in your main stack. The dialogData is a global property 
you can set and get throughout the IDE or runtime environment. 

Also make your stack modal, meaning it must be dismissed before the user can 
click anywhere else. 

Don't call a procedure in an unopened stack (unless it's script has been 
inserted into the frontScript or backScript, and that still doesn't open the 
stack to display the card. You still have to GO to the stack to do that.) 

That no workie nohow. Just go to the stack and have the openStack handler of 
your "dialog" stack call whatever procedure you have, or just have the 
openStack handler BE the procedure.

What Bob said.

In addition to using the dialogData to return the user's choice to you, you
can also use it to pass stuff into the dialog box, like maybe the text you
want to display to the user, the title, labels for the buttons, etc.  Use
the preOpenCard handler of the dialog stack to configure the dialog window
from the information you pass in via the dialogData

I tend to use  a semi-transparent image, either made in Livecode and 
exported as a snapshot as a PNG and then reimported, or with GIMP; then 
another couple of faux buttons (i.e. images) for "Yes" and "No";
just make sure that your 'answer' images are in the top layers of the 
card so they don't appear peeping out from behind whatever controls you 
have for functionality and/oe aesthetics on the card.
