It's a toy car which is controlled by a controller.
Of course it doesn't, I want to build it but what it is, is not important.
The major point I need to get is just the code for c++.

For example for moving a label in vb:
If keycode=47 then
Label1.left=label1.left+50
End If
(I'm not sure about "47", sorry)

And the one that I want in c++:
The CODE that allows me to move the car (connected with a usb cable to usb port) by the arrows.

I hope you help me by sending the CODE and thank you for replying fast.
Thanks.
