Okay i know this is simple but i started making my very own snake game. It is basically finished exept i dont know how to make the food (the little dot that the snake has to eat) just show up in a certain area. What happens is that ill eat the dot and the next dot will be somewhere to the side that i cant see.

So how do i form a border around my picture box so the snake and the dot dont go outside of it?

thanks!
