Error with a MsgBox in HTTP.au3

[chachew]

So this was not written by me and i honestly am not sure who wrote it...

The problem i get is with a MsgBox and it seems to have an undefined array in it but im not exactly sure how to resolve it. Code snippet that creates error

Func _FileUpload()
$host = "your.server"
$port = "80"
$page = ""
$vars = "action=upload"
$url = $page&"?"&_HTTPEncodeString($vars)
$socket = _HTTPConnect($host, $port)
$get = _HTTPPost_File($host,$url,$socket,@DesktopDir & "\" & $fileName , "uploadedfile")
$recv = _HTTPRead($socket,1)
MsgBox(0, "Info", "Data received:" & @CRLF & $recv[4] & @CRLF)
EndFunc ;==>End fileupload

When MsgBox(0, "Info", "Data received:" & @CRLF & $recv[4] & @CRLF) is commented out no problems but when its running in the code i get error below:

MsgBox(0, "Info", "Data received:" & @CRLF & $recv[4] & @CRLF)

MsgBox(0, "Info", "Data received:" & @CRLF & $recv^ ERROR

Now $recv[4] is an array correct? but it was never declared as a variable, any suggestions

#include <Array.au3> then use _ArrayDisplay($recv) to see what's in the array.

Or change the _HTTPRead($socket, 1) to use a flag of 0 then change your MsgBox() to use $recv instead of $recv[4].

Also, where'd you get the UDF? It might be old and needs some updating. I wish I could give you more but I'm not too familiar and have never used it. Good luck.
