朋友给段代码给你，这个代码不要任何控件，你只需要把以下代码复制到你的窗体代码中就行了,代码很简单，相信你能看懂！仅仅用了一个结构（ShenTi）一个数组（ZhuangTai(23, 23) As Long） 一个变量（GFangXiang）
十多年建站经验， 成都网站设计、做网站、成都外贸网站建设公司客户的见证与正确选择。创新互联公司提供完善的营销型网页建站明细报价表。后期开发更加便捷高效，我们致力于追求更美、更快、更规范。
代码中自动生成了Timer1，Label1控件。以及几个函数（Randomize，Circle，Line，Erase...） 相信这些对于你来说很简单，只是没想到用这些方法来实现而已，现在你开始看看效果吧！
代码如下：
