示例1: EventWatcherAsync

' 導入命名空間
Imports System.Management

' This example shows asynchronous consumption of events.
' In this example you are listening for timer events.
' The first part of the example sets up the timer.

Public Class EventWatcherAsync

    Public Sub New()
        ' Set up a timer to raise events every 1 second
        '=============================================
        Dim timerClass As New ManagementClass( _
            "__IntervalTimerInstruction")
        Dim timer As ManagementObject = _
            timerClass.CreateInstance()
        timer("TimerId") = "Timer1"
        timer("IntervalBetweenEvents") = 1000
        timer.Put()

        ' Set up the event consumer
        '==========================
        ' Create event query to receive timer events
        Dim query As New WqlEventQuery("__TimerEvent", _
            "TimerId=""Timer1""")

        ' Initialize an event watcher and subscribe to
