新手请问为什么找不到PlaySound啊？
我有在project-> setting里面加上了WINMM.LIB,程序也有#pragma comment(lib, "winmm.lib ")为什么还是会报错说PlaySound没有声明
F:\C++专题\C++源代码\Main\main.cpp(88) : error C2065: 'PlaySound ' : undeclared identifier
F:\C++专题\C++源代码\Main\main.cpp(88) : error C2065: 'SND_FILENAME ' : undeclared identifier
F:\C++专题\C++源代码\Main\main.cpp(88) : error C2065: 'SND_SYNC ' : undeclared identifier
Error executing cl.exe.

[解决办法]
PlaySound恐怕不是MFC里边的吧，应该是头文件没包含进去吧
它在mmsystem.h文件声明
[解决办法]
PlaySound()
是 Win32 API 函数，跟 MFC 没有关系。
下面是 MSDN 中关于 PlaySound() 函数的说明：
