Question: proper way to write to file?

[Aapjuh]

Hi,

I have a question about what i would take as proper practices in writing to a file like a settings.ini.
would it even matter? diskwrites vs diskreads? speed? other reasons? other methods? Does Example1 even actually write when the value is thesame?

Example1 (IniRead and IniWrite are incorrect, just an example):

$Something_Var01 = IniRead("The settings file and the corresponding value")
$Something_Var02 = IniRead("The settings file and the corresponding value")
$Something_Var03 = IniRead("The settings file and the corresponding value")
$Something_Var04 = IniRead("The settings file and the corresponding value")
$Something_Var05 = IniRead("The settings file and the corresponding value")
;...etc

;..do app stuff..

Func _Save_Ini()
    ;Even if $Var is unchanged from IniRead
    IniWrite("The settings file and the corresponding",$Something_Var01)
    IniWrite("The settings file and the corresponding",$Something_Var02)
    IniWrite("The settings file and the corresponding",$Something_Var03)
    IniWrite("The settings file and the corresponding",$Something_Var04)
    IniWrite("The settings file and the corresponding",$Something_Var05)
    ;...etc
    Exit
EndFunc

Example2 (IniRead and IniWrite are incorrect, just an example):

$Something_Var01 = IniRead("The settings file and the corresponding value")
$Something_Var02 = IniRead("The settings file and the corresponding value")
$Something_Var03 = IniRead("The settings file and the corresponding value")
$Something_Var04 = IniRead("The settings file and the corresponding value")
$Something_Var05 = IniRead("The settings file and the corresponding value")
;...etc

;..do app stuff..

Func _Save_Ini()
    ;Only if $Var is different from IniRead
    If $Something_Var01 <> IniRead("The settings file and the corresponding value") Then IniWrite("The settings file and the corresponding",$Something_Var01)
    If $Something_Var01 <> IniRead("The settings file and the corresponding value") Then IniWrite("The settings file and the corresponding",$Something_Var02)
    If $Something_Var01 <> IniRead("The settings file and the corresponding value") Then IniWrite("The settings file and the corresponding",$Something_Var03)
    If $Something_Var01 <> IniRead("The settings file and the corresponding value") Then IniWrite("The settings file and the corresponding",$Something_Var04)
    If $Something_Var01 <> IniRead("The settings file and the corresponding value") Then IniWrite("The settings file and the corresponding",$Something_Var05)
    ;...etc
    Exit
EndFunc

I'll give you my 2 cents. My 2 cents is: Do whatever you like.

Worth a few dollars IMO...

Since you're only overwriting the values you can just use IniWrite without the IniRead or use the function more efficiently, for example:

_SaveIni("Key1", "ExpectedValue1")
_SaveIni("Key2", "ExpectedValue2")
_SaveIni("Key3", "ExpectedValue3")

Func _SaveIni($_sKey, $_sValue)
    Local $sFilePath = @ScriptDir & "\FilePath.ini"
    Local $sSection = "Section"
    Local $sIniRead = IniRead($sFilePath, $sSection, $_sKey, "")
    If $sIniRead = $_sValue Then Return
    IniWrite($sFilePath, $sSection, $_sKey, $_sValue)
EndFunc

@SubzThat's a very elegant solution.

Saving for future use. Thank you.
