Can't open a file and use FileRead

Hi, I'm trying to read a file one character at a time and store it in an array, however, I keep getting error 1 on FileRead, after searching on the forums for some time and trying all solutions mentioned nothing seems to help.

 

I would greatly appreciate some help with my code.

 

#include <file.au3>
#include <FileConstants.au3>
#include <MsgBoxConstants.au3>
#include <WinAPIFiles.au3>
Global $lines[36]
$fileloc = "Z:\Autoit Projects\text\001.txt"
Func ParseMain()
   msgbox(0, "FILE", $fileloc)
   $fileOpened = FileOpen($fileloc)

   for $c = 0 to _FileCountLines($fileOpened) Step 1
      $lines[$c] = FileRead($fileOpened, $c+1)
      msgbox(0, @error, $lines[$c])
   Next
   FileClose($fileOpened)
EndFunc

I believe FileRead is reading a set number of characters from the entire file.  You can read one line at a time with FileReadLine and then use string methods to parse the characters one at a time for each line.

@‌Danyfirex has the solution

I don't see where you set the $lines array to store anything?  That array looks empty?  In either case, I believe FileRead is reading a set number of characters from the entire file.  You can read one line at a time with FileReadLine and then use string methods to parse the characters one at a time for each line.

$lines[$c] = FileRead($fileOpened, $c+1), that's where the array stores the gotten data.

FileReadLine also will not work, and still give me error 1.

 

Here's the msgbox resulting: http://i.imgur.com/XQ7JbpM.png

The error is 1 and the line read is nothing.

Try this:

#include <file.au3>
#include <FileConstants.au3>
#include <MsgBoxConstants.au3>
#include <WinAPIFiles.au3>
Local $aLines=FileReadToArray("1.txt")

_ArrayDisplay($aLines)

Local $aChars[UBound($aLines)]

For $i=0 to UBound($aLines)-1
$aChars[$i]=StringSplit($aLines[$i],"")
_ArrayDisplay($aChars[$i])
Next

_FileCountLines need a file path not a handle.

I'm not sure what it's supposed to show but it's not showing anything.

And yes, I changed "1.txt"

be sure you're using Lastest AutoIt Version.

Pass some txt example. And show in details how you need the output.

and at last you could join the arrays to a single array:

#include <Array.au3>

local $aryy[2] = ["Autoit","Programming"]
local $bryy[2] = ["is","good"]

_arraydisplay(_ArrayJoin($aryy,$bryy))


Func _ArrayJoin($ary1,$ary2)
$total = UBound($ary1) + UBound ($ary2) -2
ConsoleWrite (@CRLF &"total =" &$total)
Local $ary[$total*2]
For $i = 0 To UBound($ary1) -1
$ary[$i] = $ary1[$i]
Next
_ArrayDisplay($ary)
ConsoleWrite (@CRLF &UBound($ary1))
For $i = UBound($ary1) To $total
$ary[$i] = $ary2[$i - UBound($ary1)]
Next
$ary[UBound($ary)-1] = $ary2[UBound($ary2)-1]
Return $ary
EndFunc

my best choice goes to Kingbobs code

If all you want to do is read the text file and store each character into different elements of an array, then all you need is this.

#include <Array.au3>
Local $sLines = FileRead("1.txt")
Global $aTextArray = StringSplit($sLines, "")

_ArrayDisplay($aTextArray)

Reading one character from file. So strange. Anyways, you can use FileRead function as KingBob said.

Local $file_path = "K:\Your_Folder\Your_File.txt"
Local $readed_char = FileRead($file_path,1) ; read the help file for the second parameter of this function.
MsgBox(0,"",$readed_char)

That code works perfectly for what I want to do, thanks.
