My bad: I was thinking of bash; in LC the "move" command is for moving 
controls but not file objects.  To move files we use "rename".

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

It should.  Try checking the result immediately after, and if not empty 
call sysError() for the OS error number, e.g.:


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

Rename File on Server not working?

[Rick Harrison via use-livecode]

Hi there,

I was trying to use rename file
on the Server in a .lc script
to rename a file.  It doesn’t
seem to work at all.  Can
someone please let me know
if it works on an LC Server?

Thanks,

Database Setup

[Bob Sneidar via use-livecode]

Sooo... having shared my Database Setup card with another user, which is an 
sqlYoga wrapper if you will for connecting to mySQL and sqLite databases, I'm 
thinking about posting this in some fashion so that others can have a look, 
refine it, skin it etc. Is there such a thing for end user stuff on GitHub, or 
do I need to create my own git repository?

Restarted again and LC proceeded to the welcome screen. I clicked "open

palette, basically the IDE didn't load.

Re: Shell argv

[Mike Bonner via use-livecode]

If you are in terminal, and in the folder where your executable is, and you
type

./yourexecutablename arg1 arg2
does it do what you expect? (note the preceding dot . which means to start
at the working directory)

If the file is set to executable by you, it should work.  If you type the
command without the preceding dot slash ./ and if its not in the path, it
won't work, so you DO need to be explicit as to where it is. (hence the ./
it defines exactly where to find the file so being in the set PATH isn't
necessary)

If it DOES work that way from the command line, then in your script you can
a) set the folder to the location of the file, and then b) do a
shell("./theExe arg1 arg2") and it should work.  Or for a) you can give a
full path specification to the location of the file.

Re: Problem placing an image on the clipboard...

[Mark Waddingham via use-livecode]

The paintcompression global property is rle by default (at least in 6.7.x) - in 
the ide it gets set to png.

So try setting it to png on startup of your standalone.

Warmest regards,

Mark

Problem placing an image on the clipboard...

[Paul Dupuis via use-livecode]

Using LC 6.7.11 (yes, I know, an old version!)

I have image data in the variable tImageData and the image's width and
height in tSize and I want to copy the image to the clipboard. The
following code works perfectly EVERY time in the IDE

create inv image "pdfCopyTemp"
set the width of image "pdfCopyTemp" to item 1 of tSize
set the heightof image "pdfCopyTemp" to item 2 of tSize
set the imageData of image "pdfCopyTemp" to tImageData
set the clipboardData["image"] to the text of image "pdfCopyTemp"
wait 10 milliseconds with messages
delete image "pdfCopyTemp"

However, when I build a standalone, it fails. Adding the line "answer
(the clipboardData["image"]) right after I SET the
clipboardData["image"] show me a PNG header in the IDE and just binary
data in the standalone, no image type header. It like one built into a
Standalone, the set the clipboardData["image"] to the text of image
"pdfCopyTemp" no longer works correctly!?!

I am sure this is probably a known bug of LC 6.7.11 that is fixed in a
later  release, but is anyone familiar with this bug? Anyone know a
work-around?

Re: Shell argv

[JB via use-livecode]

Hi Mike,

Thank you for the info.

The dictionary for Shell states it needs to work
from the Terminal to work correctly with Shell so
I have been doing everything from the Terminal at
this point.  I was trying to figure out how to write
it properly in the Terminal so I could use similar
code with the Shell.

Re: Shell argv

[Mike Bonner via use-livecode]

Seems to me, if its the compiled version, you shouldn't need to use "open"
at all.

a simple
get shell("path/to/executable argument1 argument2")
If I understand what I read about "open" enough, it expects a file, that
will be opened in another app, like in Marks example.  (whatever.c opens
xcode)

If you want to experiment with open, you could try the following..

open -a /path/to/your/app /path/to/a/dummy/file/to/open --args arg1 arg2

I'm guessing that if you can format this right, it'll report the name of
the dummy file, and arg1 and arg2 as you expect.

But since you just want to pass arguments to your compiled program, I am
pretty sure you just need to use shell() and call it directly with the
arguments as part of the call.

In your original post you said "-args". The correct syntax is "--args" 
(with two dashes rather than one), so if that's not a typo in your 
original email, try correcting that and see what happens.

Re: Shell argv

[JB via use-livecode]

Hi Mark,

Thanks for the reply and info.

The file is actually named Hello and it is
a c program compiled with xcode.

It takes the argc value and if it is less than 2
returns a message a parameter was not added.
If it is 2 then it prints the value of argv[1] which
would be the first argument passed by the info
I give when opening the file.  After that no matter
what value argc is it prints the value of argv[0]
and that is always the name and path of the file.

The file executes properly and the message is printed
showing I did not enter any arguments even though I
did try to and then it prints the file name and path like
I told it to from argv[0].

What is 'my_file'?

The terminal command 'open' looks at the filename, works out what app it 
should be opened by and then launches the file in that app.


For example:

  open foo.c

Will open 'foo.c' (as a editable text file) in Xcode on my machine.

The '--args' portion of the open command allows you to pass extra 
arguments to the application which is chosen to open the file.



The argument never gets passed.  Does anyone
know how to pass arguments to argv from the
terminal when open a file so I can use the script
from a shell command?


What exactly are you trying to do?

Warmest Regards,

Mark.

Thanks Bob.

I did that before I sent the message and searched
a lot on the web.  It looks to me like I am entering
everything properly.  I will not that the file takes a
full path and I did not show a full path but I always
used a full path.  Maybe I will try compiling with
gcc sometime to see if that works.

Re: looking for a smart approach to "sort" an array

[Bob Sneidar via use-livecode]

Note also that datagrids will only display the data for columns that have been 
defined in the datagrid properties. You can have all sorts of data in the 
dgData of the datagrid that is invisible to the user. I do this all the time, 
storing whole database records, but displaying only the information I want the 
user to see. 

The drag/drop rearranging is a bit trickier, but there are lessons on how to do 
this as well. If you need to store the data as an array, simply get the dgData 
of the data grid.

Re: looking for a smart approach to "sort" an array

[Bob Sneidar via use-livecode]

Every time you state the problem you are trying to solve, I catch myself saying 
"This is not how I would do it." Array values are not searchable, which makes 
it unsuitable for searching. Fields can be searched easily enough, datagrids 
without too much more trouble are searchable, and databases are the best way to 
go about this. You can load/save the data you put into the field with 
openCard/closeCard, and let the user do whatever they want with the data 
itself. 

If all you are trying to do is let the user rearrange and save data in a field, 
why not just load/save the contents of the field in a property on 
openCard/closeCard? I do not grasp why the transform to an array is 
accomplishing anything.

Thanks for the update, Panos.

That page includes:

   Updates in the LiveCode open source project

   Notable changes
   New tsNet version: Expected in LiveCode 8.1.4 RC2


I had thought tsNet was not included in the open source edition, no?

Re: looking for a smart approach to "sort" an array

[Lagi Pittas via use-livecode]

Jim

You are a Godsend - I never knew of the metadata - I have a whole lot of
refactoring to do.
I was using the "hidden" tab fields trick but this is way better

This is going to make so much stuff so easy - and so much easier to debug

Thanks again

Use tabwidths instead of tabstops. I was working off faulty memory.
