问题描述
为了监控带宽使用情况而不是在启动时不必要地加载程序,我想执行dumeter.exe然后firefox.exe.当我关闭firefox时它应该杀死dumeter.我使用以下代码启动
To monitor the bandwidth usage and not to unnecessarily load programs in the start up,I want to execute the dumeter.exe then firefox.exe.When I shutdown firefox it should kill dumeter.I used the following code to start
Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.Run "c:\progra~1\dumeter\dumeter.exe"
WshShell.Run "c:\progra~1\mozill~1\firefox.exe
仅在关闭 firefox 时才需要运行 taskkill.尝试使用 bat 文件,但有时 dumeter 自行启动和关闭不会等待.
Need to run taskkill only when firefox is closed.Tried using a bat file but sometimes the dumeter starts and closes on its own does not wait.
WshShell.Run "taskkill /f /im dumeter.exe"
Set WshShell = Nothing
推荐答案
您可以通过订阅适当的 WMI 事件来等待进程结束.举个例子:
You can wait for a process to end by subscribing to the appropriate WMI event. Here's an example:
strComputer = "."
Set oWMI = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
''# Create an event query to be notified within 5 seconds when Firefox is closed
Set colEvents = oWMI.ExecNotificationQuery _
("SELECT * FROM __InstanceDeletionEvent WITHIN 5 " _
& "WHERE TargetInstance ISA 'Win32_Process' " _
& "AND TargetInstance.Name = 'firefox.exe'")
''# Wait until Firefox is closed
Set oEvent = colEvents.NextEvent
