Listview column problems

我有一个列表框和一个列表视图，列表框是用来查看什么程序正在运行，列表视图是过滤一个特定的进程(我在像chrome, mspaint, notepad等列出它)，当这些程序正在运行时，列表视图的"状态"列会去"活动"，当其中一个程序关闭它去不活动。我的问题是，每当一个程序关闭"状态"列保持"活动"，我怎么能改变它为"非活动"时，程序关闭?

private void running_process()
    {
            Process[] processes = Process.GetProcesses("NAMEOFPC");
           // listView1.Items[0].SubItems.Clear();
            for (int i = 0; i < listView1.Items.Count; i++)
            {
                listView1.Items[i].SubItems.Add("Inactive");
                foreach (Process p in processes)
                {
                    if (listView1.Items[i].Text == p.ProcessName)
                    {
                        listBox1.Items.Add(p.ProcessName);
                        listView1.Items[i].SubItems[1].Text = "Inactive";
                        for (int j = 0; j < listBox1.Items.Count; j++)
                        {
                            if (listBox1.Items[j].ToString() == listView1.Items[i].Text)
                            {
                                // listView1.Items[i].SubItems.Clear();

                           }
                        }
