一段曲子，C实现 很有趣-a song,implement by C

本程序是使用VB进行编写的一个关于CD播放的程序， 其基本功能：1.可以根据个人需要选择播放的音轨的格 式；2.可以在左边的列表中自由选择添加想要听取的歌 曲到右边的播放列表中，这样可以比一般的播放器节省 很多力气；3.可以点击“REFRESH CD INFORMATION”刷 新CD内音轨的信息。-use of this procedure is the preparation for the VB one on the CD player procedures, and the basic function : 1. Individuals can choose the soundtrack broadcast format; 2. The left side of the list are free to choose want to add songs to the right sidebar, this can than the average player saved a lot of energy; 3. click on the "CD INFORMATION REFRESH" CD soundtrack set of information.
