simple string match string - what am i missing?

[DarkBoost]

I have not touched AutoIT for a few months and think I am missing something very basic here as its not matching when it finds the same string result: iso iso

Dim $a = StringSplit("microsoft.windows.7-professional-x86.iso", ".")   ;example of file listing
Dim $b = StringSplit("zip, rar, cab, iso", ",")                         ;supported extensions
Dim $xtn = $a[$a[0]]                                                    ;will find/display ISO

For $x = 1 To $b[0]
    If $xtn = $b[$x] Then MsgBox(0, "", "Extension: " & $xtn & @CRLF & "Match: " & $b[$x])
Next

Your string in $b[$x] is not "iso", it's " iso". Either declare the array without the spaces or do a StringTrimWS() on it.

You could also just run it through a RegExp for more geeky goodness:

Global $aFiles[5] = ["Test.me.zip", "File.for.testing.rar", "One More - File .cab", "microsoft.windows.7-professional-x86.iso", "NonMatch.exe"]
For $n = 0 To UBound($aFiles) - 1
    If StringRegExp($aFiles[$n], "(\.zip|\.rar|\.cab|\.iso)\Z", 0) Then
        ConsoleWrite($n & ": Match" & @LF)
    Else
        ConsoleWrite($n & ": No match" & @LF)
    EndIf
Next
