保持运行的C ++程序控制台顶部？ [英] Keep a running C++ program console on top?

问题描述

假设我在我的程序中使用 cin ，以允许用户输入到控制台。这很简单，但如果他们正在输入，比方说，一个Web浏览器，我想让他们同时输入到控制台？当我点击远离C ++程序控制台窗口，并在顶部有其他东西，输入显然不会进入控制台。如何使控制台总是运行在最上面，这样即使我在浏览器中输入内容，它也会进入控制台？

Let's say I was using cin in my program to allow the user to input into the console. That is simple enough but what if they were typing into, let's say, a web browser and I wanted them to input that into the console at the same time? When I click away the C++ program console window and have something else on top, the input obviously does not go into the console. How can I make it so the console is always running on top so that even when I were to input something into a web browser, it would also go into the console?

推荐答案

为了捕获键盘输入，当您的应用程序不专注时，您需要使用Windows钩子，请参阅：

in order capture keyboard input when your application is not focused, you need to use windows hook, see:
