关于PlaySound函数的用法详解
我把我在学习使用PlaySound函数时遇到的问题与大家探讨一下:
下面是我写的一个win32汇编程序，关于PlaySound有如下几点说明：
1.在使用它时要添加下面的语句
include winmm.inc;包含PlaySound的声明
includelib WINMM.lib
如果不包含以上语句，编译器会对PlaySound报错，这个问题可能是很多初学者会遇到的。
2.BOOL PlaySound(PCSTR pszSound,HMODULE hmod, DWORD fdwSound);
如果在第三个参数中指明了SND_FILENAME，那么只要在第一个参数中指明音乐文件的正确路径并将第二个参数写为NULL即可；
但如果第三个参数中指明的是SND_RESOURCE时，我使用罗云彬书上第五章179（第二版）上讲的使用自定义资源的方法来做可没成功。
不知我哪错了，希望高手帮忙解决，补充完PlaySound的用法，好为初学者指点津。
