Need urgent help opening .txt files.

Hello. I need urgent help. I need to edit my code by tomorrow so my program allows me to select a .txt document, open it, and place the text from the file in a text field.
The code I have below only opens up the .txt file called numbers on the desktop. I need to change it so it will allow me to open any document.
Code: Select all
global fileChoice
global listOfNumbers
global n
global numbers
on mouseUp
readInData
putDataInArray
displaydata
end mouseUp
on readInData
open file specialFolderPath("Desktop") & "/numbers.txt" for read
read from file specialFolderPath("Desktop") & "/numbers.txt" until eof
put it into listOfNumbers
read from file file until eof
close file fileChoice
end if
end readInData
on putDataInArray
local i // integer
put the number of words in listOfNumbers into n
repeat with i= 1 to n
put word i of listOfNumbers into numbers[i]
end repeat
end putDataInArray
displayData
Help is hugely appreciated!

Sorry I am new to livecode and dont understand how to get that to work so it reads the data from inside the text file. Does anyone know what changes I can make to my code so instead of just reading from the file on the desktop it allows me to select the file using answer file?

Why does it read until EOF twice?
If you're reading the entire file, it may be simpler to use "put url...":
Code: Select all
put url ("file:"& specialFolderPath("Desktop") & "/numbers.txt") into listOfNumbers
But as for why it doesn't work as you have it, hard to say. Have you put in any error checking, looking at the value of "the result" and/or "sysError()" after the open and read commands?

More or less like Richard said...
Code: Select all
on mouseUp
answer file "Choose a text file to open" of type "TEXT"
if it is not empty then
put URL ("file:" & it) into fld 1
end if
end mouseUp
