1 Introduction

Originally wanted to write a Snake game, you can play on Windows Mobile, but because I have to point presentation tribal gatherings, the results did not have time to write, but to become a snake wall

2. Methods

On the functions of the program, that is, when the snake Collage hit the screen, the game is over, the program flow is as follows

(1) obtain the screen resolution in order to hit the wall when the snake died, refer to rotate the screen orientation previous article [Windows Mobile], get the screen resolution and size of the work area

(2) for recording variable declarations global coordinates

(3) Menu clicking on the Start button, so Timer operation, and according to the direction of the user clicks with the updated coordinates, and determines whether a wall

(4) in the form Paint event, drawing the snake out
