#include <file.au3>
#Include <Array.au3>
HotKeySet( "{ESC}", "end" )
Func end()
    Exit 0
EndFunc
$file = FileOpen("v.txt", 0)
If $file = -1 Then
    Exit
EndIf
If $file = -1 Then
    Exit
EndIf
Dim $file
If Not _FileReadToArray("v.txt",$file) Then
   MsgBox(4096,"Error", " Error reading log to Array     error:" & @error)
   Exit
EndIf
For $x = 1 to $file[0]
Next
_ArrayDisplay($file)
FileClose($file)

The script is working but When I add or change in the v.txt file the new value is not displayed.

Could you help me guys .

$file is the handle returned by FileOpen(), then you wiped out the value when you used DIM to declare it again, so the file is open but you don't have the handle anymore, and _FileReadToArray() can't reopen the file. Don't confuse the issue by reusing your variables like that:

#include <file.au3>
#Include <Array.au3>

Global $sFile = "v.txt", $aFile[1]
Global $hFile = FileOpen($hFile, 0)
If $file = -1 Then
    Exit
EndIf
If Not _FileReadToArray($hFile, $aFile) Then
   MsgBox(4096,"Error", " Error reading log " & $sFile & " to Array     error:" & @error)
   Exit
EndIf

_ArrayDisplay($aFile)
FileClose($hFile)

Unless you're constantly reading the contents of the v.txt file you're only going to get the contents the first time you read in the file, it's not going to monitor it for changes the way you've written it.

@PsaltyDS

_FileReadToArray can't use a file handle, it needs the actual file path and filename. I believe he was using the fileopen as a means of checking to see if the file is there.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

_ArrayDisplay will pause the script untill you close that win, to display new data you need to...

close _ArrayDisplay win,

to recall _FileReadToArray one more to reread new entered data and

call _ArrayDisplay to openup one more time to display it

maby your need something diffrent like GUI commands, GUICtrlCreateListView for example, instead of _ArrayDisplay?

_FileReadToArray can't use a file handle, it needs the actual file path and filename.

Oops. I thought I remembered those being updated to accept handles, so you could FileOpen() in specific non-standard modes. My bad.

I took a look at the File.au3 file and the first command in the _FileReadToArray function is a FileOpen command, which is probably why it has to have a filename and path.

Which, coincidentally, means that there's no reason to use a FileOpen before calling the _FileReadToArray function, because all you'd need to do is look at the return values of it to see if the file is there or not, or at least whether it can be opened or not.

Look at _FileWriteFromArray() code in the UDF. It will take a file handle for $File so you can open it in an alternate Unicode format, or you can pass the string path and it will FileOpen() for you in default format. I just thought I remembered that capability being spread to more of the functions in File.au3 than it really was. The wonders of the aging brain...
