Hi there.

Recommended Posts

I have had some experience with Autoit, but I'm no expert...did some point and click :) I think Autoit and you guys might help me.

I have a 20000 rows txt file, long lines of information.

Every line contains ex: default_price=2000451

I need to multiply and replace in text 2000451 by 2 all lines, for example.


Can anyone help me please?

Thank you in kind.

Welcome to the AutoIt forums. :)

This should give you a good idea of how to do what you want:

#include <File.au3>
#include <Array.au3> ; Only for demo

; ---------------------------------------------
; Simuate reading in file
$sLines = "default_price=1" & @CRLF & _
    "default_price=2" & @CRLF & _
    "default_price=3" & @CRLF & _
    "default_price=4" & @CRLF & _
$aLines = StringSplit($sLines, @CRLF, 1)
; ---------------------------------------------

; You would use code like this to read it
; Global $aLines
; _FileReadToArray("File_Path", $aLines)

; And this is what we get
_ArrayDisplay($aLines, "Original", Default, 8) ; Only for demo

; Now extract the number and double it before resetting each line
For $i = 1 To $aLines[0]
    $aSplit = StringSplit($aLines[$i], "=")
    $aLines[$i] = $aSplit[1] & "=" & (2 * $aSplit[2])

; And here is the result
_ArrayDisplay($aLines, "Doubled", Default, 8) ; Only for demo

; Now rewrite the file like this
; _FileWriteFromArray("File_Path", $aLines, 1)
Please ask if you have any questions. :)


P.S. Although I think doubling prices is a bit steep. Perhaps you might get more help if you only raised them by 50%! :D
