References: Hooks can monitor various event messages in the system or process, intercept messages destined for the target window, and process them. In this way, we can install a custom hook in the system, monitor the occurrence of specific events in the system, complete specific functions, such as the interception of keyboard, mouse input, screen Word, log monitoring and so on. It is obvious that using hooks can achieve many special and useful functions. Therefore, for senior programmers, it is necessary to master the hook programming method.

These days have been learning about the Hook of the relevant knowledge, and then they did a fun small program, the main function of statistics one day the mouse moved how many meters, as well as how many times the keyboard percussion, from the beginning of this blog count, hehe, I think it is very fun.
