Win32_WindowsProductActivation WMI类和SetProductKey方法的问题.
当我运行使用WMi Code创建者生成的此代码(vbscript)时,执行失败并显示错误Invalid参数
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
' Obtain an instance of the the class
' using a key property value.
Set objShare = objWMIService.Get("Win32_WindowsProductActivation")
' Obtain an InParameters object specific
' to the method.
Set objInParam = objShare.Methods_("SetProductKey"). _
inParameters.SpawnInstance_()
' Add the input parameters.
objInParam.Properties_.Item("ProductKey") = "QW4HDDQCRGHM64M6GJRK8K83T"
' Execute the method and obtain the return status.
' The OutParameters object in objOutParams
' is created by the provider.
Set objOutParams = objWMIService.ExecMethod("Win32_WindowsProductActivation","SetProductKey",objInParam)
' List OutParams
Wscript.Echo "Out Parameters: "
Wscript.echo "ReturnValue: " & objOutParams.ReturnValue
但如果我使用此代码工作正常,使用InstancesOf方法.
Dim VOL_PROD_KEY
VOL_PROD_KEY = "QW4HDDQCRGHM64M6GJRK8K83T"
for each Obj in GetObject("winmgmts:{impersonationLevel=impersonate}").InstancesOf ("win32_WindowsProductActivation")
result = Obj.SetProductKey (VOL_PROD_KEY)
if err <> 0 then
WScript.Echo Err.Description,"0x" & Hex(Err.Number)
Err.Clear
end if
Next
静悄悄是
@R_301_323@
规则是,如果执行的wmi方法是静态的,你可以使用theSpawnInstance_否则调用直接传递参数的方法
这里有静态和非静态方法的描述.
Static methods apply only to WMI
classes and not to specific instances
of a class. For example,the Create
method of the Win32_Process class is a
static method because use it to create
a new process without an instance of
this class. Nonstatic methods apply
only to instances of a class. For
example,the Terminate method of the
Win32_Process class is a nonstatic
method because it only makes sense to
terminate a process if an instance of
that process exists. You can determine
if a method is static by checking if
the Static qualifier is associated
with the method.
