Hello guys, why doesn't the first script display anything while the second one works fine?

Please help me understand. Thank you!

Great. But best to post the solution so someone doesn't ask in the future what was it?

#include <Constants.au3>

ConsoleWrite(ListOnline() & @CRLF)

Func ListOnline()
    Local $iPID = Run(@ComSpec & " /c net view ", @SystemDir, @SW_HIDE, $STDOUT_CHILD)
    Local $sActiveLine = "", $sLines = ""
    While 1
        $sActiveLine = StdoutRead($iPID)
        If @error Then ExitLoop
        $sLines &= $sActiveLine
    WEnd
    Return $sLines
EndFunc   ;==>ListOnline
