C＃應用程序，在後臺工作，並注意到其他打開的應用程序及其路徑

Question

我想使應用程序停留在後臺並記下哪些應用程序在前臺打開並記錄它們的路徑。誰能告訴我，如果它可能和如何去做

Answer 1

這是可能的。您可以使用WMI和Win32_ProcessStartTrace來追蹤新流程何時開始，並使用這些信息來查找其路徑。

Answer 2

這裏是一個MSDN文章： http://msdn.microsoft.com/en-us/library/aa720671(v=vs.71).aspx

下面是一些InstanceCreationEvent下調代碼：

private void subscribeToProcessStartEvents() 
    { 
     string pol = "3"; 
     string queryString = "SELECT * FROM __InstanceCreationEvent WITHIN " + pol + " WHERE TargetInstance ISA 'Win32_Process'"; 
     ManagementEventWatcher watcher = new ManagementEventWatcher(queryString); 
     watcher.EventArrived += new EventArrivedEventHandler(watcher_EventArrived); 
     try 
     { 
      watcher.Start(); 
     } 
     catch (Exception e) 
     { 
      MessageBox.Show("Error Occurred: " + e.ToString()); 
     } 
    } 

    public void watcher_EventArrived(object sender, EventArrivedEventArgs e) 
    { 
     ManagementBaseObject proc = ((ManagementBaseObject)e.NewEvent["TargetInstance"]); 
     MessageBox.Show(DateTime.Now.ToString() + ": Process " + proc["Name"] + " with Path: " + proc["ExecutablePath"] + " Has Started"); 
     //To see the arguments used: 
     string commandLineString = proc["CommandLine"].ToString(); 
    }
