Best way to do a file check/re-write

[Damein]

So I have an INI with a bunch of different items in it. And in the program you can change a value of a section that corresponds to a different section. Now, to stop duplicates and also be able to continue adding to the ini correctly I wanted to see what the easiest way would be.

I know this probably sounds confusing or something, but I'll try to explain.

Statuses.ini

[Status]
1=Partly Cloudy
2=Isolated T-Storms
3=Mostly Cloudy
4=Mostly Sunny

[XY]
Partly Cloudy=45,200
Isolated T-Storms=37,200
Mostly Cloudy=45,200
Mostly Sunny=47,200

So that is how the ini is setup. The Status section is the text for the label, and the XY is the X,Y location for the label.

$CheckForDuplicate = IniReadSection("Statuses.ini", "Status")
  For $i = 1 To $CheckForDuplicate[0][0]
   If $CheckForDuplicate[0][1] = $OverViewStatus[1] Then
    $MsgBox = MsgBox(4,"Duplicate entry", "A duplicate entry has been found, over write previous alignment?")
    If $MsgBox = 7 Then
     ExitLoop
    Else

Now with this code I'll check for duplicates, but if I find one, what would be the best way to over-write it easily? Also, I'll need a section for if there is no duplicate. Would I need to do a FileReadLine, add +1 to the value for the INI Status and then add the X,Y, as well?

Just looking for some suggestions on the best way to do this, thanks

Better approach will be to avoid creating duplicates instead of removing them post.

I think with different INI structure it avoid duplicates:

[Status]
1=Partly Cloudy|45,200
2=Isolated T-Storms|37,200
3=Mostly Cloudy|45,200
4=Mostly Sunny|47,200
