在不冻结GUI的情况下运行另一个进程 [英] Running another process without GUI freezing

问题描述

在运行(和等待)外部进程时，我无法显示我的GUI并且无法冻结.在这种情况下，drivers.exe是一个非常简单的程序，用户只需单击确定"即可.因此，每当我单击确定"时，它就会退出.我试图在执行driver.exe时简单地使我的状态栏计数增加(非常快).但是实际上，在driver.exe退出之前，我的GUI根本不会出现.

I'm having trouble getting my GUI to appear and not freeze while running (and waiting for) an outside process. In this case, drivers.exe is a very simply program where the user simply clicks "OK". So whenever I click OK, it exits. I am trying to simply make my status strip count numbers up (really fast) as drivers.exe is executing. But in practice, my GUI never appears at all until drivers.exe exits.

private void run_drivers()
        {
            Console.WriteLine("Start Driver");
            int driver_timeout_in_minutes = 20;
            System.Diagnostics.Process driverproc = System.Diagnostics.Process.Start(Application.StartupPath + "\\" + "drivers.exe");
            driverproc.WaitForExit(driver_timeout_in_minutes * 1000 * 60);   //uses milliseconds, we must convert
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            ThreadStart worker = new ThreadStart(run_drivers);
            Console.WriteLine("Main - Creating worker thread");
            toolStripStatusLabel1.Text = "hi";
            Thread t = new Thread(worker);
            t.IsBackground = true;
            t.Start();
            Console.WriteLine("Main - Have requested the start of worker thread");

            int i = 0;
            while (t.IsAlive)
            {
                i++;
                toolStripStatusLabel1.Text = i.ToString();
            }
            Console.WriteLine("Dead");
        }
