Replace a value in a text file

[mohan93]

Hey Guys,

Hope this is a simple task for most of us, But am lost here by not using a proper command.

Scenario is,

1. I have a file under Appdata location, in which i want to change a value.

File location:

C:Usersef_U274864AppDataLocalSmartView3.2.639.0user.config

Inside this file in line 29 i have the below line hardcoded to particular user.

<value>C:UsersMohanComputerAppDataRoamingFlukeSmartView3.2.639.0DefaultUserSettings.xml</value>

when want to replace the name harcoded here so that this file can be used in other machine with there particular user name.

like after replacing

<value>C:UsersShyamComputerAppDataRoamingFlukeSmartView3.2.639.0DefaultUserSettings.xml</value>

i used the below code to replace the whole line 29.

 

#include <File.au3>

$File = @AppDataDir & "LocalSmartView3.2.639.0user.config"

$Replace = <value>@AppDataDirRoamingFlukeSmartView3.2.639.0DefaultUserSettings.xml</value>;

MsgBox(1, "File location", $File)

_FileWriteToLine($File, 29, $Replace, 1)

Am not successfull in using the script.

Any anyone help me with different approach for changing the harcoded username entry in the file.

Thanks in Advance.

Cheers,

Mohan

Something like this ?

#Include <File.au3>

Local $sFile = "C:\Users\ef_U274864\AppData\Local\SmartView\3.2.639.0\user.config"
Local $sReplace = "<value>" & @AppDataDir & "\Fluke\SmartView\3.2.639.0\DefaultUserSettings.xml</value>"

Local $aOriginal = FileReadToArray($sFile)
Local $aNew [ UBound($aOriginal)]


For $i = 0 TO UBound($aOriginal) - 1
    
    If StringRegExp( $aOriginal[$i], "<value>C:\\Users\\\w+\\AppData\\Roaming\\Fluke\\SmartView\\3\.2\.639\.0\\DefaultUserSettings\.xml</value>") Then
        $aNew[$i] = $sreplace
    Else
        $aNew[$i] = $aOriginal[$i]
    EndIf
Next

_FileWriteFromArray($sFile, $aNew)

mohan93,

Your code is correct except for this

$Replace = "<value>" & @AppDataDir & "\Fluke\SmartView\3.2.639.0\DefaultUserSettings.xml</value>;"

Edit

I'm running XP so not sure about the 'roaming'

Hi,

Your replacement syntax string is wrong, you need to wrap it inside quotes or single quotes.

Plus, you can't concat anything (here the AppDataDir) without the & character.

$Replace = "<value>" & @AppDataDir & "\Roaming\Fluke\SmartView\3.2.639.0\DefaultUserSettings.xml</value>"

Br, FireFox.
