4. Display the number scrolling effect;

5. Easy to operate interface, beautiful design, friendly.

I and Wang Xiaolong a group, we after two hours of time, made the drawing of the Small Program page. and added a small function timing function. But the code hasn't been written yet.

There are a lot of problems that don't, like;

• What controls should be used to display the number scrolling effect when drawing lots?
• Just finished the random draw interface.
• Estimated to be completed in 2 weeks.
• Whether the database is used in the display of extracted data
• What controls are used to display information in the database
• How do you write code because there are too many controls?
