Read array from INI file --- non-array Variable error


Recommended Posts

Hello,

I am writing a program that can scan an ini file for a list of software. If I have the script look at a populated ini file, it runs fine. When the ini file has no keys or values, I get a subscript error.

Can someone look at my code to what I am doing wrong please?

;Check Software.ini file to populate list
$iCount = IniReadSection("C:\Program Files\App\Software.ini", "ApplicationName")
If @error Then
 IniWriteSection("C:\Program Files\App\Software.ini", "ApplicationName", "", "")
 IniWriteSection("C:\Program Files\App\Software.ini", "Install", "", "")
 Sleep(4000)
EndIf
_ArrayDisplay($iCount)
For $i = 1 To $iCount[0][0]
 _GUICtrlListView_AddItem($listSoftware, $iCount[$i][0] & " " & $iCount[$i][1])
 _GUICtrlListView_AddSubItem($listSoftware, $i, "Scanning...", 1)
 _GUICtrlListView_AddSubItem($listSoftware, $i, "Scanning...", 2)
 _GUICtrlListView_AddSubItem($listSoftware, $i, "Scanning...", 3)
Next

I added the @error because I realised that if there isn't an ini file, the script wouldn't be able to create an array. However, even with a blank ini file, it still doesn't work.

This is the error:

(52) : ==> Subscript used with non-Array variable.:

For $i = 1 To $iCount[0][0]

For $i = 1 To $iCount^ ERROR

Thanks for any help.

Look at using @error or even IsArray.

If IsArray($iCount) Then ; Ideally this should $aCount as it's an Array.
    For $i = 1 To $iCount[0][0]
        _GUICtrlListView_AddItem($listSoftware, $iCount[$i][0] & " " & $iCount[$i][1])
        _GUICtrlListView_AddSubItem($listSoftware, $i, "Scanning...", 1)
        _GUICtrlListView_AddSubItem($listSoftware, $i, "Scanning...", 2)
        _GUICtrlListView_AddSubItem($listSoftware, $i, "Scanning...", 3)
    Next
EndIf

Did you look in the help file for IniReadSection? The return for it is a blank string with @error set to 1, if you get an error you're not getting an array. Creating the ini file, but not reading it again afterwards isn't going to do any good. Also, if the section exists, but it's empty, you're also going to end up with an empty array or a string (not sure on this) so it's going to give you an error again.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Thank you both! Guinness, thank you the IsArray was exactly what I needed.

I do read the helpfile (it's awesome), and it gave me the idea to use @error. I also tried reading the ini file into a variable again after creating the ini if it didn't exist.

I couldn't get around the problem that it may have no values on a first time use. I didn't even think about IsArray (not a function I've used much to be honest).

I appreciate both of your help and advice as always!

Thanks!

IsArray is OK, but I rarely use it because more often than not proper error checking can avoid using this e.g. with the code above you could have done this instead >>

; Check Software.ini file to populate list
Local $aArray = IniReadSection("C:Program FilesAppSoftware.ini", "ApplicationName"), $sListSoftware
If @error Then
    IniWriteSection("C:Program FilesAppSoftware.ini", "ApplicationName", "", "")
    IniWriteSection("C:Program FilesAppSoftware.ini", "Install", "", "")
    Sleep(100)
Else
    _ArrayDisplay($aArray)
    For $i = 1 To $aArray[0][0]
        _GUICtrlListView_AddItem($sListSoftware, $aArray[$i][0] & " " & $aArray[$i][1])
        _GUICtrlListView_AddSubItem($sListSoftware, $i, "Scanning...", 1)
        _GUICtrlListView_AddSubItem($sListSoftware, $i, "Scanning...", 2)
        _GUICtrlListView_AddSubItem($sListSoftware, $i, "Scanning...", 3)
    Next
EndIf
