Focus on the mouse simulation, the principle and the same as the keyboard. Find the Mouseclassservicecallback function in the drive Mouclass.sys, then get the //device//pointerclass0 device object pointer, construct the MOUSE_INPUT_DATA structure, Then call Mouseclassservicecallback. The difficulty lies with the structural mouse_input_dat
I have mentioned that I would like to introduce this software to benefit more people. I am very busy recently. I would like to give a look at it. If you are interested in it, please feel free to go over the resources at the end of the article.

Using socket + instrumentation to simulate keyboard and mouse events consists of the following three parts:Socket programming: Implements PC-to-emulator communication and loop listeningService: place the socket listener in the service to run the program in the background. Here, we need to note that there are two ways to start a service: bindservice and startservice. The difference between the two is that th
