Msgbox Filter

Hi... Im new on autoit,Tried so many things different but no  sucess. Anyway.

This is the code

Func BuildChatArray()
    Local $array[1][2], $pointer, $item_base, $counter, $lastchatpointer, $Lastmsg
    $lastchatpointer = _MemoryRead($LASTCHAT, $PROCESS_INFORMATION)
    $Lastmsg = ($lastchatpointer - 10)
    For $i=$Lastmsg to $lastchatpointer - 1
        $pointer = _MemoryRead($ChatBase, $PROCESS_INFORMATION)

            ReDim $array[$counter + 1][2]
            $array[$counter][0] = _MemoryRead($pointer + $i * dec("1c") + 0x4, $PROCESS_INFORMATION, "Byte") ;SN
            $array[$counter][1] = _MemoryRead(_MemoryRead($pointer + $i * dec("1c") + 0x8, $PROCESS_INFORMATION), $PROCESS_INFORMATION, 'wchar[100]') ;Name
            if $array[$counter][0] = 0 Then
                addhistory($array[$counter][1])

Do

addhistory($array[$counter][1])

SoundPlay("Alien.wav")


MsgBox(64, 'Finished', 'Y' & $array[$counter][1])

sleep(1000)
until 1 = 1
endif
$counter += 1


Next

_ArraySort($array, "", "", "", 6)
;_ArrayDisplay($array)
Global $ChatArray = $array
sleep(10)
EndFunc ;==>
