How to check if the mouse control is inside VM console?

Hi,

I'm opening a vcloud director vm console in a browser through an automation script and moving my mouse control to the vm console.

i want to verify whether the mouse pointer is inside the vm console or in the physical machine.

Is there a way in which i can find out where the mouse control is ?

what would be the difference in the properties of a mouse control when it is inside a vm console and physical machine ?

Thanks
