如何在VC中播放声音文件？

PlaySound("msg.wav", 0, SND_ASYNC | SND_FILENAME );

PlaySound 看看MSDN，就这么用，一行代码高定

放wav文件用PlaySound
其他的好像可以用mciSendString播放

PlaySound只能播放WAV文件，如果你需要其他功能的话，还是用DirectSound吧

兄弟，给点小代码给你看一下吧

兄弟，这是它的头文件，上面是实现
#ifndef __MIDI_H__
#define __MIDI_H__#include <mmsystem.h>class CMidi
{public:
CMidi();
~CMidi(); int DeviceCount( void );//获得播放设备 BOOL Open( const char * );//打开MIDI文件
BOOL Close( void );//关闭MIDI文件 BOOL Play( void );//播放MIDI文件
BOOL Stop( void );//停止播放MIDI文件
BOOL Pause( void );//暂停播放MIDI文件
BOOL IsPlaying( void );//是否正在播放 BOOL GetLength( int *, int * );
int GetMinutes( void );
int GetSeconds( void ); BOOL SeekTo( int, int );
BOOL SkipForward( int );
BOOL SkipBack( int ); int GetTempo( void );
BOOL SetTempo( int );protected:
BOOL m_bOpened, m_bPaused, m_bPlaying;
WORD m_wDeviceID;
int m_nDevices;};#endif
