Array not being built?

Recommended Posts

So I've written a fairly lengthy TCP Client with the help of a friend. But I have an issue.

So I've declared an array.

This is an example script; since the real one is hardly reasonable to post and it jumps around way too much. lol.

Global $Necessary[1] = ["0"]

$Recv = TCPRecv($hSockeet, 1024, 1) ;Contains nullbytes sometimes.
$Recv = BinaryToString("0x" & $Recv, 4)
$sMethod = StringSplit($Recv, ".", 2)

Switch $sMethod[0]
Case 1
  $nSearch = _ArraySearch($Necessary, $sMethod[1] & "." & $sMethod[7])
  If $nSearch = -1 Then
    _ArrayAdd($Users, $sMethod[1] & "." & $sMethod[7])
    ConsoleWrite($sMethod[1] & "." & $sMethod[7] & @CRLF)

There's of course plenty more but that's the only part where data is added to the $Necessary array. And thats the only array that breaks. If I try and perform an array display later, it doesn't even bring up as if the array was deleted. So any ideas?

Edit: I got sidetracked by ordering pizza. But the script DOES work sometimes. It's just a gamble, only 9 times out of 10 you lose and have to try again. And the data IS being received. I've even traced inside the loop and I can CLEARLY see it.

Edit 2: So after a many month long battle and lots of putting off. Having written out what my problem was, the solution became resoundingly obvious to me. I'll never know for sure what the issue was, but doing if IsArray then declaring the variable again fixed it. Thank you Autoit forums, you have in a weird way helped me.
