d4rkdz,

Give us a chance to help you. Please post an example of the file and explain how you want the data sorted. At the moment we would just be whistling in the dark if we suggested anything at all. ;)

P.S. All we need is a few lines of the file - post it with [code] before and [/code] after the text so it appears neatly in a box. :)

Can you explain why you have to read them randomly and then sort them?

Can't you just read the whole file to an array, sort it and then access the records?

How large is the file we are talking about?

I don't feel like doing all the work, but I came up with some code for randomizing an array of number, which could be used to randomize a length of file lines to read. The OP should at least try something. Don't expect others to write all your code for you.

#include <array.au3>

Global $listOfNumbers[100]

For $i = 1 to 100 Step 1
$listOfNumbers[$i - 1] = $i
Next

_RandomizeSet()

Func _RandomizeSet()
For $i = 1 to 100 Step 1
_ArraySwap($listOfNumbers[Random(0, 99, 1)], $listOfNumbers[Random(0, 99, 1)])
Next
EndFunc

_arraydisplay($listOfNumbers)

d4rkdz,

From that less than helpful post I take it you are looking to sort a list of usernames in a random manner. If that is indeed the case, i recommend that you read the file into an array with _FileReadToArray and then use jchd's excellent random sort algorithm on it. :)

thanks that was helpful and i got it done , sorry for the poor explanation

#include 
#include 
Local $data
_FileReadToArray("users.txt",$data)
local $count=_FileCountLines("users.txt")
For $i = UBound($Data) - 1 To 1 Step -1
$j = Random(1, $i, 1)
$Temp = $Data[$j]
$Data[$j] = $Data[$i]
$Data[$i] = $Temp
Next
_ArrayDelete($data, 1)
For $x = 0 To $count-1
MsgBox(0, 'user:' & $x, $data[$x])
Next
