can I edit a line in a .txt file?

[cyanidemonkey]

I am trying to edit a config file (cfg file below)

Say I want to edit maxplayers = 8 (line 24) to 'maxplayers = 12'

How do I do this? I've tried FileWrite & FileLineWrite but they add a line at the bottom

Use IniRead & IniWrite.

Just replace the // to [ and ] and there you have it.

EDIT: you may have to change that file a bit more formatting wise though.

this file is being use by another application and that is how it writes it out,

I'd like to be able to control the way it works by editing its config file directly

You could probably change the // to [] like the above poster said. Thats actually the only thing you need to change. However the script would haveto change it back to the way it was. I assume thats a server config for a game and the game wouldnt understand [] i guess.

The problem with using IniRead/IniWrite is that you need the [] or it wont find what you are looking for

yeah, it's server config for a game.

How do I rewrite the // to [] ?

I figure I have to open/edit the file first to rewrite the // to [] , then use IniWrite to edit the settings, then switch [] to //

[huldu]

You only haveto add a [] at the beginning of the file. For example [GAME], then you have IniWrite do something like this:

IniWrite($File, "GAME", "Maxplayers", "12")

The thing is i dont know how to make FileWrite change the first line. The config never repeats a variable, which is a good thing... thats why you only need 1 [GAME] at top.

Here try this, should at least get you started before someone makes it better:

#include <file.au3>
$File = FileOpenDialog("FILE TO WORK WITH", @ScriptDir, "ALL (*.*)")

Dim $Change = "maxplayers"
Dim $Value = 7 
ChangeSomething($File, $Change, $Value)

Func ChangeSomething(ByRef $FilePath, ByRef $ChangeWhat, $Value)
    Local $nArray
    Local $NewFile = @ScriptDir & "/TempTest.txt"
    _FileReadToArray($FilePath, $nArray)
    _FileCreate($NewFile)
    For $i = 1 To UBound($nArray) - 1
        If StringInStr($nArray[$i], $ChangeWhat) Then
            $Split = StringSplit($nArray[$i], '=')
            $nArray[$i] = StringReplace($nArray[$i], $Split[2], " " & $Value)
        EndIf
        FileWriteLine($NewFile, $nArray[$i])
    Next
    FileDelete($FilePath)
    FileMove($NewFile, $FilePath)
EndFunc

Nice one SmOke_N,

That works well, cheers

[cyanidemonkey]

When I try to call the function I get an error, is there a different way to call functions with refences?

GUICtrlCreateLabel ("Maximum Players:", 30,60,90,20)
$MaxPlayers = GUICtrlCreateCombo ("", 117,57,40,80)
GUICtrlSetData(-1,"1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16", $gMaxPlayers)
        
Dim $Change = "maxplayers"
Dim $Value = $MaxPlayers

GUICtrlSetOnEvent($MaxPlayers, "ChangeSomething($File, $Change, $Value)" )

Func ChangeSomething(ByRef $FilePath, ByRef $ChangeWhat, $Value)
    Local $nArray
    Local $NewFile = @ScriptDir & "/TempTest.txt"
    _FileReadToArray($FilePath, $nArray)
    _FileCreate($NewFile)
    For $i = 1 To UBound($nArray) - 1
        If StringInStr($nArray[$i], $ChangeWhat) Then
            $Split = StringSplit($nArray[$i], '=')
            $nArray[$i] = StringReplace($nArray[$i], $Split[2], " " & $Value)
        EndIf
        FileWriteLine($NewFile, $nArray[$i])
    Next
    FileDelete($FilePath)
    FileMove($NewFile, $FilePath)
EndFunc

Does this work?

GUICtrlCreateLabel ("Maximum Players:", 30,60,90,20)
$MaxPlayers = GUICtrlCreateCombo ("", 117,57,40,80)
GUICtrlSetData(-1,"1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16", $gMaxPlayers)

GUICtrlSetOnEvent($MaxPlayers, "CallChanges")

Func CallChanges()
    Local $File = 'FilePath'
    Local $Change = 'maxplayers'
    Local $Value = GUICtrlRead($MaxPlayers)
    ChangeSomething($File, $Change, $Value)
EndFunc

Func ChangeSomething(ByRef $FilePath, ByRef $ChangeWhat, $Value)
    Local $nArray
    Local $NewFile = @ScriptDir & "/TempTest.txt"
    _FileReadToArray($FilePath, $nArray)
    _FileCreate($NewFile)
    For $i = 1 To UBound($nArray) - 1
        If StringInStr($nArray[$i], $ChangeWhat) Then
            $Split = StringSplit($nArray[$i], '=')
            $nArray[$i] = StringReplace($nArray[$i], $Split[2], " " & $Value)
        EndIf
        FileWriteLine($NewFile, $nArray[$i])
    Next
    FileDelete($FilePath)
    FileMove($NewFile, $FilePath)
EndFunc

Edit: I'm assuming your only showing partial code (I hope so anyway)...

Don't forget you need #inlude <File.au3>

Yes that works, thanks Smoke N

And yeah, I had just dropped in the snippet of code before, the includes and stuff are @ the top of my script.

Cheers for your help. Now it's going for one control I need to get it to update maybe half the lines in the config file, each from a different control in the GUI.

Would it be better to put a GUICtrlSetOnEvent on each of the controls or would all the opening/copying/rewritng/deleting/moving of the file on every event change be a problem and maybe I should run the function once and update all options from all controls at the same time triggerd by a single event?

[SmOke_N]

I'm not a fan of GUICtrlSetOnEvent, I'd rather just use: $msg = GUIGetMsg() and a case statement.
