Simple Description:
This program is to modify a mouse program in C-only advanced programming. The original program cannot display the mouse in the XP system.
I implemented the system-implemented mouseon and mouseoff functions by myself, and added a mousestatus.
This function is used to determine the mouse State. Therefore, it is best to use a completed mousestatus function to determine the mouse state.
The main principle of the program is to use the program to realize the difference or. */
