三国志11 古武将:ScriptContext

这段代码是MSDN上的VBSCRIPT例程，但运行时提示缺少对象: 'ScriptContext',应如何修改？

Const EVENT_TYPE_SUCCESS = 0
Const EVENT_TYPE_ERROR = 1
Const EVENT_TYPE_WARNING = 2
Const EVENT_TYPE_INFORMATION = 4
Const EVENT_TYPE_AUDITSUCCESS = 8
Const EVENT_TYPE_AUDITFAILURE = 16

CreateEvent 100,EVENT_TYPE_INFORMATION,"Script Test","Hello world."

Sub CreateEvent(intEventNumber,intEventType,strEventSource,strEventMessage)
Set objEvent = ScriptContext.CreateEvent()
objEvent.EventSource = strEventSource
objEvent.EventNumber = intEventNumber
objEvent.EventType = intEventType
objEvent.Message = strEventMessage
ScriptContext.Submit objEvent
End Sub
