无聊编了一个电子琴的自定义控件，可以实现多种风格的电子琴，而且控件非常好用，放在窗体上就是一个电子琴，附带一个测试用的Demo，有兴趣的下载来玩玩，呵呵。PS:那个钢琴键盘是我自己画的，呵呵，很不错吧-Bored compiled a custom keyboard , you can achieve a variety of styles of keyboards, but the controls are very easy to use , on the form is a flower , with a test of the Demo, downloads are interested to play, huh.
