说明：  闲暇时自己写的一个VC++指针时钟，带闹钟功能，附上所有源码，闹钟时间到，会响起来，其实是调用了一段音频，请注意把编译生成的程序放到Debug对应目录里，确保加载声音文件正确
(Spare time to write a VC++ pointer clock with alarm function, attach all source code, the alarm time, will be sounded, in fact, is an audio call, please note that the compiler generates the corresponding program into the Debug directory to ensure that Canada sound files contained the correct)
