任何人都知道如何让我的VB.net应用程序等到检测到进程正在运行?
我可以找到一旦exe运行完毕后如何检测但没有检测到exe何时启动的示例?
您可以使用
System.Management.ManagementEventWatcher等待某些WMI事件发生.您需要为其提供一个查询类型和条件,让它监视您的进程的下一个创建,然后让它在发生时执行某些操作.

Dim watcher As ManagementEventWatcher Public Sub Main() Dim monitoredProcess = "Notepad.exe" Dim query As WqlEventQuery = New WqlEventQuery("__InstanceCreationEvent",new TimeSpan(0,1),"TargetInstance isa ""Win32_Process"" And TargetInstance.Name = """ & monitoredProcess & """") watcher = New ManagementEventWatcher() watcher.Query = query 'This starts watching asynchronously,triggering EventArrived events every time a new event comes in. 'You can do synchronous watching via the WaitForNextEvent() method watcher.Start() End Sub Private Sub Watcher_EventArrived(sender As Object,e As EventArrivedEventArgs) Handles watcher.EventArrived 'Do stuff with the startup event End Sub
最终你需要停止观察者,你可以通过关闭应用程序或调用watcher.Stop()来做.这是作为脑编译器编写的,所以如果有任何问题请告诉我.
