直接上代码

#include <Windows.h>char szRet[1024];void play(){    char szCmd[] = "open  waveaudio!1.wav alias mysound";    DWORD dwRet = mciSendStringA(szCmd, 0, 0, 0);    if(dwRet !=0)    {        qDebug()<< "open error "<<dwRet;        return;    }    char szCmd2[] = "play mysound";    dwRet = mciSendStringA(szCmd2, 0, 0, 0);    if(dwRet !=0)    {        qDebug()<< "play error "<<dwRet;    }}void stop(){    char szCmd[] = "stop mysound";    DWORD dwRet = mciSendStringA(szCmd, 0, 0, 0);    if(dwRet !=0)    {        qDebug()<< "stop error "<<dwRet;        return;    }    char szCmd2[] = "close mysound";    dwRet = mciSendStringA(szCmd2, 0, 0, 0);    if(dwRet !=0)    {        qDebug()<< "stop error "<<dwRet;    }}

简单的使用，play stop

在配置文件当中添加依赖库：Winmm.lib

LIBS += -lWinmm
