Could you develop this project with HTML5/JavaScript in a "wrapper" for Android 
and iOS deployment?

Thanks for your help, problem solved!

The problem wasn't actually that I forgot the group (i did in the email but not 
my code), the problem was that I was deleting a group from a Data Grid in a 
script contained in a button in the group being deleted, which is a Thing Not 
To Do To Avoid Needless Suffering!

Changed it to "dispatch" and all is well!

Thanks!

Thanks for the reply Zryip!

I can't get dgDataControlOfIndex to work, anyone know of any code examples?


hide btn "blueCircle" of dgDataControlOfIndex[2]

and

hide btn "blueCircle" of grp dgDataControlOfIndex[2]

both result in errors, so I'm going to hack a solution based on the long id of 
the graphic with cached controls on. Thanks for trying though!

How do I reference an image in a group in a Data Grid form from outside the grid?

[Josh Mellicker]

Just wondering what best practices are when wanting to reference an image (or 
button or other non-text field control) in a Data Grid form.


img "blueCircle" of grp x of grp "DataGrid"

works, but x does not seem to correlate with either the index or line number.


So, does anyone know:

1. what x is?

2. how to get x (the group number of the group containing the image) when the 
image is clicked on?

3. Any other way to easily reference a control in a Data Grid form?

Thanks in advance!

Re: SFTP externals

[Josh Mellicker]

It would be great if it were able to resume upload or download in the case that 
the file had only partially been transferred previously. If you are using cURL, 
I believe this is the "-T" switch.

-T is a godsend when transferring larger files over intermittent connections, 
since the file does not need to start over at the beginning whenever there's a 
glitch in the matrix... just picks up where it left off.

Hmmm…. I stand corrected. Now, we are getting an error message when trying to 
execute the sudo command.

"sudo: no tty present and no askpass program specified"

So, we are going to take Shao's sagely advice and try ~/Library/Application 
support.

Yes:

In Snow Leopard and previous:

1. the Livecode command "create folder" WORKS in /Library/Application Support/
(note this is not in the user folder)

2. files CAN be downloaded to folders within that folder

(As Richard noted, this is when the current logged in user is the admin user, 
which for us is 99.9% of the time)



In Lion:

1. the Livecode command "create folder" does NOT work in /Library/Application 
Support/
(but executing a shell command sudo mkdir does work)

2. files can NOT be downloaded to folders within that folder
(but after a shell command changing permissions to 777, this fixes it)


---

On the topic of "where do we put stuff (needed support files) in OS X", I 
remember Ken Ray had a great article on this… we decided on 
/Library/Application Support/, it has been working great until yesterday :-)

We are now changing on OS X so that support files will be downloaded and housed 
inside the Mac application package in the Applications directory.)



[OT] By the way, many people write web apps in Javascript, HTML5, PHP, etc., 
and have nightmares about browser incompatibilities, while we are very happy to 
write desktop apps in Livecode that are far faster to develop and offer a much 
better user experience. (In a sane world 95% of developers would work in 
Livecode and only the crazy few would deal with writing web apps.)

However, there's always the client objection of "we don't want to make the user 
install an app". (Whereas the same clients feel it's fine to require the user 
to install Silverlight, Adobe AIR, a new version of the Flash plugin, a Java 
app, or some other plugin to use their web app)

So, Ken Ray wrote us some ultra-cool installers that make installing our app 
faster and easier than any of the browser plugin, effectively making a Livecode 
app just as easy for the user, if not easier than many web applications. If you 
want an awesome installation experience, Ken is your guy!

So, think "Beyond the Browser" (R. Gaskin quote), the web is dead, we are now 
in the Age of the App!

Lion problem report and fix

[Josh Mellicker]

Just wanted to let everyone know, Lion permissions default to not allowing 
Livecode to create folders in "/Library/Application Support/" with the "create 
folder" command.

Here's how we got around it:

First, this

   put "mkdir" && quote & "/Library/Application 
Support/theNewFolderWeNeed2create" & quote into tCmd
   get shell (tCmd)
   put it

returns "Permission denied".


But this:

   put "sudo mkdir -p" && quote & "/Library/Application 
Support/theNewFolderWeNeed2create" & quote into tCmd
   get shell (tCmd)
   
creates the folder, and oddly, does not prompt for the password, at least in 
the IDE (haven't tried with a standalone yet).

Then, this:

   put "sudo chmod -Rfv 777" && quote & "/Library/Application 
Support/theNewFolderWeNeed2create" & quote into tCmd
   get shell (tCmd)

makes it so that folders and items can be freely created in the new folder by 
Livecode on Lion. So everything is back to normal a la the Leopards.


Hope this helps someone out.


And, if anyone has a better way, please post!
