使用WMI和VBSCRIPT检查TPM准备情况

Question

如果我使用这个WMI方法'。IsEnabled'应该我关心我是如何处理我的if语句的结果。如果一个方法返回bool值，我还可以使用Not吗?还是应该做类似

的操作?

if myStatus <> 0 OR isTPMEnabled <> True then

我的代码

function isTPMReadyToBeOwned(myTPMService)
        dim myStatus, isTPMEnabled, isTPMActivated, isTPMOwnershipAllowed
        myStatus = myTPMService.IsEnabled(isTPMEnabled)
        if myStatus <> 0 or not(isTPMEnabled) then
            oLogging.CreateEntry "TPM isn't enable and must be enabled and activated manually, errorcode " & Hex(myStatus), LogTypeWarning
            isTPMReadyToBeOwned = False
            exit Function
        end If
        myStatus = myTPMService.IsActivated(isTPMActivated)
        If myStatus <> 0 or not(isTPMActivated) then
            oLogging.CreateEntry "TPM isn't active and must be activated manually, errorcode " & Hex(myStatus), LogTypeWarning
            isTPMReadyToBeOwned = False
            exit Function
        end If
        myStatus = myTPMService.isOwnershipAllowed(isTPMOwnershipAllowed)
        if myStatus <> 0 or not(isTPMOwnershipAllowed) then 
            oLogging.CreateEntry "TPM ownership is not allowed, errorcode " & Hex(myStatus), LogTypeWarning
            isTPMReadyToBeOwned = False
            exit Function
        end If
        isTPMReadyToBeOwned = True
    end Function

布尔表达式/变量不应该与布尔文字进行比较，因为它增加了额外的复杂性(操作符和操作数)。所以用Not isTPMEnabled。由于Not既不是函数也不是数组，所以不要使用参数列表/index ();Reserve()用于优先级重写的情况。

更新wrt注释:

()在VBScript中有(太多)功能

1. 函数调用参数列表():x = f(y, z)
2. index (): a = SomeArray(4711)
优先级:2 + 3 * 4 = 14，(2 + 3)* 5 = 25

()在布尔表达式中只能是类型3
