Putting a text file into variable with URL method not working

[montymay]

Hello

It's been a while since a posted a help request because I suspended work on my project, but I'm back on it and could use any suggestions that would correct the following unexpected outcome.

The code below, written for a text field containing a list of topics, with listbehavior and locktext set to true, formerly worked but now the variable tText remains empty after running the code:

Code: Select all

on mouseup
   put "D:/Documents/DB/guides/" into tFolder
   put the selectedtext of me into tTopic
   put url ("file:"&tFolder&tTopic&".txt") into tText
   set the htmltext of fld "guide" to tText
end mouseup

The path to the folder containing the text files with the file name being the selected line, is correct. I am running LC 9.6.1. Thank you for any suggestions.

Hi,
This syntax is strange for me

Code: Select all

put url ("file:"&tFolder&tTopic&".txt") into tText

What happend with that instead:

Code: Select all

put tFolder & tTopic & ".txt" into tFile
put url ("file:" & tFile) into tText

Best regards

Hi Monty,

This works for me !
- differences - I'm only looking for files in the same folder of my stack

Code: Select all

      ## Get the contents of the file
      put URL ("file:" & tFileName) into tFileContents
      ## Display the file contents in the field
      put tFileContents into field "Result"

as you see, very few " " " ... involved - this way is to run it on linux.

*also under windows : some path used symbol will depend if meant for a 32 bits platforms or 64 bits...

Hello

Thanks to those who replied. I hope I did not waste too much of your time. I found the problem: there is a hidden character at the beginning of each line of the list field. Modifying the script to delete it fixed the problem. I don't know what the character is or how it got there but will investigate. If there is a way of revealing the hidden character, it would be of interest to others, I think.

Sounds a lot like what I found in this post

If there is a way of revealing the hidden character, it would be of interest to others, I think.

whatever character is "hidden" in some way, could be made "visible" when using a Textconversion LC feature;

So just by converting it to another format would show it as a string.
Using a "regex" filter, could also help to instantly remove undesired string wherever it is encountered !
..then you just need to save the "sanitized" string as you wish.

Text "converting" :

...and more

Regex use case :

just an idea
