对这个程序的源代码做了详细的说明。因此它可以做为学习windows消息体制的范例，当然也可以做为32位汇编语言学习的参考资料。(不能作为16位汇编的发音程序的范例,因为我是直接调用的声卡API接口函数,从而隐藏了用直接控制硬件(比如定时器,扬声器)的方法.-Of the source code of this procedure a detailed descr iption. Learning so it can be used as an example of windows message system, of course, can also be employed as the compilation of 32 language learning reference. (Can not be used as compilation of 16 examples of the pronunciation of the procedure, because I am a direct call to the sound card interface API function, and thus hidden by the direct control of hardware (such as timers, speakers) method.
