Access specific line of a text file stored in /Contents/Resources?

I’m trying to access a specific line of a text file that I have in /Contents/Resources. I can display an image from the folder without any problem, but can’t get it to open a text file. The code I have is:


	if name of theObject is equal to "solution" then
		set solutionpath to POSIX path of (path to me) & "Contents/Resources/solutions.txt" as string
		open for access file solutionpath
		set solutions to read solutionpath
		close access solutionpath
		set rebussolution to item 1 of solutions
	end if

The button is “solution” and when clicked I want it to open solutions.txt and display the line currently set a item 1, but it will later be changed to a variable set elsewhere in the program. When it stops throwing up errors at this point I’ll have it display the resulting text string, probably in a dialog. Every time I click the button I get told:

Seems to silly that it doesn’t work. It seemed like it would be such a simple thing!

Edit:

Okay, so I’ve made some progress. I can get it to do what I want it to when the file is on the desktop, but I just can’t get it to open a file stored within the app itself. This code seems to work great, but the commented out line I just can’t get to work:

	
if name of theObject is equal to "solution" then
		--set solutionpath to POSIX path of (path to me) & "Contents/Resources/solutions.txt"
		set solutionpath to (path to desktop as string) & "solutions.txt" as alias
		set solutions to read solutionpath
		set solutions to paragraphs of solutions
		set rebussolution to item newrebus of solutions
		display dialog rebussolution
	end if

You should try to use built-in functions as much as possible. The bundle object for your application (“main bundle”) has a handful of commands that return paths common to all asstudio apps. Using this will always return the correct value, so you don’t risk messing up by trying to hack together a path by creating it manually. Not that there aren’t times where you need to manually construct a path, but in this case the “resource path” command returns exactly what you’re looking for, so all you need to do is append your file name and you’re golden. Also, realize that you don’t have to open or close files to read from them. That’s only necessary when writing.

I recommend defining your path only once, possibly in a separate initialization handler, and saving it in a persistent variable. It cleans up your code significantly, especially if you’re going to be making frequent or repeated calls to the file you’re reading from or writing to. You probably also want to add in some error-checking, as you’ll throw an error if the file is corrupt or doesn’t exist.

property pathDataFile : ""

on clicked theObject
	set dataFileContent to read (POSIX file pathDataFile)
	log dataFileContent
	set dataFileLine2 to paragraph 2 of dataFileContent
	log dataFileLine2
end clicked

on launched theObject
	set pathResources to (resource path of main bundle) as string
	log pathResources
	
	set pathDataFile to (pathResources & "/Data.txt") as string
	log pathDataFile
end launched

Thanks jobu, you’ve come to my rescue once again! (I’d actually missed the reply to the thread and given up. Back to work now though!)
