Return Value for incorrect number in Array variable

[7121]

I wish to know is there a return value whenever the array variable has an incorrect?

#Include <File.au3>
#Include <Array.au3>
$sFilter = ""
$iFlag = ""
$FileList=_FileListToArray(@DesktopDir)
If @Error=1 Then
    MsgBox (0,"","No Folders Found.")
    Exit
EndIf
If @Error=4 Then
    MsgBox (0,"","No Files Found.")
    Exit
EndIf
$msg = MsgBox(0, "", $FileList[23] )

_ArrayDisplay($FileList,"$FileList")

\Desktop\Testing.au3 (14) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:

If not, is there a way to sort of EXIT, before the last number is hit or some way to detect that it's at the end?

When using '_FileListToArray' index zero of the array returns the Number of Files\Folders found.

using the following would show all the indexs without going out of range.

For $i = 1 To $FileList[0]
    MsgBox(0, $i, $FileList[$i])
Next

Always use UBound for arrays. That's the no. 1 measure against errors of that kind.

#Include <File.au3>
#Include <Array.au3>
$sFilter = ""
$iFlag = ""
$FileList=_FileListToArray(@DesktopDir)
If @Error=1 Then
    MsgBox (0,"","No Folders Found.")
    Exit
EndIf
If @Error=4 Then
    MsgBox (0,"","No Files Found.")
    Exit
EndIf
If UBound($FileList)-1 >= 23 Then 
    $msg = MsgBox(0, "", $FileList[23] )
Else
    $msg = MsgBox(0, "", $FileList[UBound($FileList)-1] )
EndIf

_ArrayDisplay($FileList,"$FileList")

As explained above, always carefully check the upper bound of an array before accessing its elements.

Or else it's going to be as much sensical to the interpretor as if I ask you to give me what you're holding in your 5th hand. You're likely to look at me strangely and think I'm in a state of sin.

THANK YOU THANK YOU!, that really worked for me.

I have another question however, i noticed that the array seems to list the files by DATE and TIME, anyway to sort it by name instead?
