PlaySound同时播放两wav

能不能用PlaySound同时播放两个WAV文件？如果能，怎么弄？
谢谢了！
mciSendCommands函数是不是vc++的？
如果是，编译预处理用加些什么头文件？

Answer 1

mciSendCommand函数可以同时播放两个音乐

MCIDEVICEID dev[20];
MCI_OPEN_PARMS mciOpen;
MCI_PLAY_PARMS mciPlay;
{
mciOpen.lpstrElementName="./music/1.mp3";
if(mciSendCommand(NULL,MCI_OPEN, MCI_OPEN_ELEMENT ,
(DWORD)&mciOpen)==0)
dev[0]=mciOpen.wDeviceID;
else
mciOpen.wDeviceID=dev[0];

mciPlay.dwFrom = 0;
mciSendCommand(mciOpen.wDeviceID,MCI_PLAY,MCI_NOTIFY | MCI_FROM,(DWORD)&mciPlay);
}
{
mciOpen.lpstrElementName="./music/2.mp3";
if(mciSendCommand(NULL,MCI_OPEN, MCI_OPEN_ELEMENT ,
(DWORD)&mciOpen)==0)
dev[1]=mciOpen.wDeviceID;
else
mciOpen.wDeviceID=dev[1];

mciPlay.dwFrom = 0;
mciSendCommand(mciOpen.wDeviceID,MCI_PLAY,MCI_NOTIFY | MCI_FROM,(DWORD)&mciPlay);
}

Answer 2

两个线程就可以
参照AfxBeginThread函数，看看工作者线程

Answer 3

异步模式播放即可
