请教函数“_ServListInstalled”的用法。[附上代码了] [已解决]

dreamgg

想列表出系统服务到日志文件，按照“ServiceControl.au3”内含例子里的方法总是报错，请赐教！

#include <Array.au3>
Func _ServListInstalled($Computer = ".")
    Local $Rtn = ''
    $Service = ObjGet("winmgmts:\" & $Computer & "\root\cimv2")
    $sItems = $Service.ExecQuery("Select * from Win32_Service")
    For $objService in $sItems
        $Rtn &= $objService.Name & '|'
    Next
    Return StringSplit(StringTrimRight($Rtn, 1), '|')
EndFunc
_ArrayDisplay(_ServListInstalled(),"test")

报错信息：
F:\My Documents\code\listserv\1.au3(25,42) : ERROR: _ArrayDisplay() called with expression on Const ByRef-param(s).
_ArrayDisplay(_ServListInstalled(),"test")
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^

Const ByRef-param(s)

什么意思？

语法错误

#include <Array.au3>
Func _ServListInstalled($Computer = ".")
    Local $Rtn = ''
    $Service = ObjGet("winmgmts:\\" & $Computer & "\root\cimv2")
    $sItems = $Service.ExecQuery("Select * from Win32_Service")
    For $objService in $sItems
        $Rtn &= $objService.Name & '|'
    Next
    Return StringSplit(StringTrimRight($Rtn, 1), '|')
EndFunc
$test=_ServListInstalled()
_ArrayDisplay($test,"test")

应为以上


楼主帮助没看清，英文也不行


_ArrayDisplay的首项是要返回已声明的变量的

看到Const ByRef，想想就清楚了


建议看帮助和恶补英文

非常感谢楼上的管理员先生，对于脚本和英文都是初学，正在努力提高。
