yzkzero(Skall You):
你是在哪加的啊！
我是在BOOL CTestDialogApp::InitInstance()
客户区初始化的时候加的！运行是没有错，可是“当”一下后就没声音了！
tks！！

InitInstance()里加也可以

我是加在SetRegistryKey(_T("应用程序向导生成的本地应用程序"));后面

如果要重复的话：

PlaySound(_T("G:\\TLJ\\GETDOWN.WAV"),NULL,SND_ASYNC|SND_LOOP);

我可以的，代码如下：

加入Winmm.lib
#include <Mmsystem.h>

PlaySound(_T("G:\\TLJ\\GETDOWN.WAV"),NULL,SND_FILENAME);

我以c:\1.wav为例
用：
PlaySound(PSTR,HMODULE,DWORD)；
PlaySound("c:\\1.wav",NULL,SND_FILENAME|SND_ASYNC);
也添加了winmm.lib
头文件加的windows.h
还是出错了！我在初始化和view类里分别添加了以上代码，都有错！应该在什么地方加啊?
报错如下：
F:\object\TestDialog\TestDialogView.cpp(62) : error C2065: 'PlaySound' : undeclared identifier
F:\object\TestDialog\TestDialogView.cpp(62) : error C2275: 'PSTR' : illegal use of this type as an expression
