MFC C++ 后台线程-C/C++问题

MFC C++ Background Thread(MFC C++ 后台线程)

本文介绍了MFC C++ 后台线程的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在制作一个 MFC(文档/视图)应用程序，我希望它在后台持续监听设备何时连接，然后自动复制设备上的文件，而无需用户交互或暂停/打扰什么他们在做.

I am making an MFC (document/view) application and I want it to constantly listen in the background for when a device is connected and then automatically copy the files on the device without the user needing to interact or pause/disturb what they are doing.

创建工作线程和创建后台线程一样吗?我会将它创建为文档文件中的函数还是单独的类?

Is creating a worker thread the same as having a background thread? Would I create it as a function in the document file or as a separate class?

谢谢，

推荐答案

是的，它们就像一个普通的后台线程，你有一个获取参数的函数，然后你可以进入你的监听循环.我会把这个函数放在单独的类中，也许是单例类的形式，这样你就可以轻松地启动/停止你的设备监听器.如果您需要将此工作线程的进度信息发送到 GUI，请使用 PostMessage 到您的 GUI 窗口.

Yes, they behave as a normal background threads, you have a function that gets parameter, and then you can enter your listener loop. I would put this function in separate class, maybe in a form of a singleton class, this way you can easily start/stop your device listener. If you would ever need to send information of progress from this worker thread to GUI, use PostMessage to you GUI windows.
