Read/Write file

[jeanvouillon]

Hi,
I have tried to read/write a txt file, following the tutorial (http://lessons.runrev.com/spaces/lesson ... he-iPhone-).
My stack works fine in the 4.2 iPad simulator, but when I deploy it on a real 4.2.1 iPad, it doesn't work anymore: when I try to get the information from the file, I just get its filename instead...
Did I missed something obvious? Any suggestions?
Thanks.

Hi Jean,

could you please post the relevant script(s)?

Hi Klaus,

I kept it simple:

A 'save' button:
on mouseUp
set the defaultFolder to specialFolderPath("documents/")
put URL ("file:notes.txt") into field "notes"
end mouseUp

A 'open' button:
on mouseUp
set the defaultFolder to specialFolderPath("documents/")
put field "notes" into URL ("file:notes.txt")
end mouseUp

In the simulator it's working fine, but on the iPad "notes.txt" is displayed in the field when the open button is clicked...

Hi Jean,

...but on the iPad "notes.txt" is displayed in the field when the open button is clicked...

IS displayed or IS NOT displayed?
If its displayed, what is your problem?

You could check the result after saving and loading of the file.
"the result" should be empty after successful writing/reading of the file.
...
put fld "notes" int URL...
answer the result
...

Same after loading.

Hi Klaus,
Sorry for the confusion.
When I wrote that "notes.txt" was displayed, it's mean that the name of the file was displayed, instead of its content...

I'm going to check the result,
Thanks for the advice

Hi again,
The result is "Can't open file" when I try to write or read the file...

Hi Jean,

ah, sounds like a permission problem.
Maybe the Defaultfolder did not get set?

Try this to avoiid setting the defaultfolder:
...
put URL ("file:" & specialFolderPath("documents") & "/notes.txt") into field "notes"
...
put field "notes" into URL("file:" & specialFolderPath("documents") & "/notes.txt")
...

Thanks Klaus for the solution and your fast answer!

Bonsoir Jean,

we memorize:
Setting "the defaultfolder" does not work as exspected on iOS (yet)

Bon nuit, mon ami!
