This is where some sort of "get out quickly" phrase is needed.

Yesterday one of my 12 year old 'victims'  was getting her feet wet with 
her first SWITCH statement,

and got badly bogged down, and we found that

exit switch

seemed to work a bit better than

break

the 'funny' thing is that the Dictionary (err: "Hitch Hiker's Guide to 
the Galaxy") says they are synonymous; but, as we linguists say 'no 2 
words are ever completely synonymous'.


I suppose a GOTO statement would be really good; especially as, although 
Livecode scripts
supposedly don't have line numbers, there are those numbers down the 
left-hand side :/


The only bother about those numbers is that every time one pops a bit of 
code into one's script they will refer to different places.


This sort of thing might not be bad:


put 1 into XX
repeat until XX>7
  do something
put 1 into ZZ
repeat until ZZ>7
  do something else
 put 1 into YY
repeat until YY>7
ask "What colour are you socks?"
   if it contains "purple" then
   goto %%%
   end if
   add 1 to YY
 end repeat
  add 1 to ZZ
  end repeat
   add 1 to XX
end repeat
%%%

Re: Nested Repeat loops

[jbv]

In some cases I managed to replace "repeat for" with
"repeat while" and thus eliminating the flag and the
test on it since the condition is in the repeat loop itself.

Re: Nested Repeat loops

[Geoff Canyon]

It's hard to say without context, but one way to handle things like this is
to fold it all into a function/handler. Then if you want to exit you can
exit/return.

Maybe I've completely failed to understand what it is you don't like 
about your current method, but...


Would it be practical and feel cleaner to wrap your nested repeats 
inside a command, say,'doLoop'. When your 'if' condition in the nth 
repeat is met, you 'exit doLoop'. You only have to reference and check a 
condition once this way and you cleanly exit the entire nested structure 
exactly when and where the condition is found.


A useless example that works:

Create a card with four fields and a button. Put this script in the button:


 on mouseUp
   doLoop
   answer "exited loop"
end mouseUp

on doLoop
   repeat 10 times
  add 1 to field 1
  repeat 10 times
 add 1 to field 2
 repeat 10 times
add 1 to field 3
repeat 10 times
   if field 3 is 3 then exit doLoop
   add 1 to field 4
end repeat
 end repeat
  end repeat
   end repeat
end doLoop

Re: Nested Repeat loops

Its not always easy, or worth the trouble, but putting the whole nested 
structure in a separate handler lets you use the exit command.

Windows pathing question

[Bill Vlahos]

I want to sent a command line command to a Windows executable to pass 
information and a command to it so that the application dials the phone number 
I send it (it is a telephony application). The command works fine if I specify 
the complete path.

Is there a way I can issue the command without explicitly defining the path or 
asking the user to find the navigate to the application and I store the path?

Re: Compile IOS Externals

[Mark Wilcox]

Hi,

This external is only a couple of lines of code - I very much doubt it
doesn't compile, you probably have a linking problem.

If you post the errors then maybe it'll be easy to solve and it might
also provide valuable learning for other externals.

Is this a direct copy/paste? This line is malformed:

Remove the trailing "then". Also, the image name is misspelled as 
"imegeField1" ("e" rather than "a") which is more likely the reason for 
the problem.

Note that the OSX shell command should actually be

Check for running application in Windows

Good afternoon!

Is there a way to check to see if there is a program currently running on a
Windows machine?  For instance, I want to verify that a 3rd party piece of
software is currently running (not just installed) before proceeding with
my LC script.

As usual, your comments and suggestions are always appreciated!

Image control in a Background

[Vaughn Clement]

Hi All

I asked this question recently and I did not get any responses.

I have a substack with a background group where there is an Image Control
is being populated using the

mobilePickPhoto "library"

The image is added to the control correctly and displays, but if I leave
the card and return the image is gone.

To solve this the image is stored in the folder on in the app as per this
script:


*on* mouseUp

   /* the image from mobilePickPhoto uses the template image construct

   set it off screen so we don't see ift flash */

   *set* the loc of the templateImage to -1,-1

   /*choose a photo*/

   mobilePickPhoto "library"

   *lock* screen

   *if* the result <> "cancel" *then*

  /* make the filepath to save the chosen image*/

  *put* specialFolderPath("documents") & "/photos/" & the short ID of
this card into thePath

  /* put the image into a file in the photos folder */

  *put* the text of the last image of this card into URL("binfile:" &
thePath)

  /*set the loc of image 1 to the loc of group "picgroup' so it will
align*/

  *--set the loc of  image "imageField1" to the loc of group "picgroup"*

  /* show the image on the card */

  *set* the filename of image "ImageField1" of this card to thePath

  /* destroy the image imported from the library */

  *delete* the last image of this card

   *end* *if*

*end* mouseUp

The image control is supposed load when the card opens and the last photo
is to be displayed?


*on* openCard

   *set* the defaultfolder to specialFolderPath ("documents") & "/photos/"

   *--answer the files*

   *if* the number of this card >1 *then*

  *set* the defaultfolder to specialFolderPath ("documents") &
"/photos/" *then*

 *if* there is a file the short id of this card *then*

*put* specialFolderPath ("documents") & "/photos/" & the short
ID of this card into thePath

*set* the filename of image "imegeField1" of this card to
thepath

 *end* *if*

  *end* *if*

*end* openCard

Several different changes were tried and the image still will not load into
the card as scripted above.


Can anyone reference the information or see what might cause this issue?


Thank you

Achieving highest resolution output

[dfepstein]

I hope someone can help me understand printing resolution. 

If I use LiveCode to generate a PDF that will be printed at 300 dpi, how do I 
achieve the best output? For vectors, I assume that it makes no difference at 
what scale I compose the picture. (Is that true?) But suppose I want to print a 
bit map 1 inch wide. I would tell LiveCode to "print into rect 0,72,0,72" (for 
example) to indicate that it should be 1 inch square. Will this work better if 
the original bit map is 300 pixels wide (to match the intended 300 dpi 
resolution)? Or if it's a multiple of 72, like 288, pixels wide? 

Further suppose that I want some 9 point text on my 1 inch square. For the case 
where I'm printing 288 pixels of width into a rectangle that is 72 wide, it 
seems clear I can compose with 36 point text. But if I'm printing 300 pixels 
into that 72 wide rectangle, will 36 be slightly too small? Should I use 37 
point text? 

Is composing at 300 pixels better for the bit map quality but 288 pixels better 
for getting the right the text size? 

Thanks for any guidance.
