The callback function can be installed on Microsoft's mouse drive. When there is event, the callback function is driven, and the status of the mouse can be queried in the callback function, and then the corresponding change is set to reflect the state change of the mouse.

Now there is only a binary target file, I will use the image of the binary file Copy Screen, uploaded to my album, you can use the binary editor to restore this OBJ File, then link this file with the file you generated
