This is a very interesting small program developed by learning hook over the past few days to measure the distance between mouse movement and the number of mouse clicks.

Reference: hooks can monitor various event messages in the system or process, intercept and process messages sent to the target window. In this way, we can install custom hooks in the system to monitor the occurrence of specific events in the system and complete specific functions, such as intercepting keyboard and mouse input, and retrieving words on the screen, log monitoring. As you can see, hooks can be used to implement many special and useful functions. Therefore, it is necessary for senior programmers to master hook programming methods.

I have been learning for the past few days. Hook And then made a fun littleProgram, The main function is to count how many meters the mouse moves in a day, and how many times the keyboard hits, from this article Blog Start counting. Haha, I think it's quite fun.

In order to avoid closed doors, the program directly uses Georgi Of Useractivityhook Class, which is simple and suitable for my program. Of course, in the previous articles, you will find a class library with better functions. ^ 0 ^

Questions raised by 81:

C # I also wrote a keyboard hook. At that time, I wanted to swap [and {to get the key value, but the swap always didn't work. I finally did it. I wonder whether the landlord can implement it?
There is no time to write this program for the moment, but you can first start with the idea, first judge the key value obtained from the hook keyboard event,
If it is a "{" key value, the keyboard event is simulated to send the "[" key value message, and vice versa}

About 16 MB of memory usage:
The reason is that the class array is used and the length is very large, so it is inevitable...
I will improve it if I have the opportunity.
