Read and Write to Line.

[RvS]

Hi,

I'm currently trying to create a little GUI for editing a .ini file.

What it needs to do is replace the "resolution 800 600" on Line 4 with "resolution $variable"

When I use

$file = FileOpen("file.ini", 2)

; Check if file opened for writing OK
If $file = -1 Then
    MsgBox(0, "Error", "Unable to open file.")
    Exit
EndIf

FileWriteLine($file, "Line1")
FileWriteLine($file, "Line2")
FileWriteLine($file, "resolution " & $GUI_CBOX_WIDTH)

FileClose($file)

I used this scrap (which doesnt do what I want but I can write the entire line by myself too, I dont care)

It will write me lines, but it will replace the variable with "6" or "1" where I pick 800 600 from the Combobox.

Here's the combobox and variables:

Global $GUI_CBOX_WIDTH = GUICtrlCreateCombo("Pick a width (pixels)", 112, 240, 121, 25)
        GUICtrlSetData(-1, $RESOLUTIONS, "")

$RESOLUTIONS = "800|1024|1280"

Help please =[

maybe GUICtrlRead .

also for writing ini file you can use IniWriteSection and IniWrite functions

edit : that's its syntax GUICtrlRead($GUI_CBOX_WIDTH) ; GUICtrlRead with the control id

The edit: helped me fix the output problem, but Im not sure how to replace Line 4. I have to keep the rest intact:

quality 1

screen 1

shadow 1

resolution 800 600

username roger

lastname doe

I need to keep the rest the same, and only change "800 600" and replace it with whatever I put as variable $GUI_CBOX_WIDTH

EDIT:

This ini file wont work with:

[section]

value=1

The structure of lines has to be preserved and it can only make:

value 1

If you know it is always line 4, then you just do this:

_FileWriteToLine($file, 4, "resolution " & GUICtrlRead($GUI_CBOX_WIDTH), 1)

.

If not, read the whole file into a string, edit the string, then write it back to the file.

If you want to get tricky, read the file to an array, search the array for the old value and change it, then write just that element or the whole array back to the file.

You have lots of options here.
