mciSendString　占用句柄解决思路

mciSendString　占用句柄
我想用mciSendString来播放音乐，很简单的几句话，发现调用一次后，里面就有句柄未释放，如果循环调用，情况会更糟，不知道是否我哪里没有写正确，现在帖上来，希望大家帮我分析下．谢谢．

C/C++ code

    CString s, s2;    s2 = _T("D:\\aa.mp3");    while (1)    {        s.Format(_T("open \"%s\" type MPEGVideo alias OpenFile"), s2);        MCIERROR me=mciSendString(s, NULL, 0, 0);        mciSendString(_T("Play OpenFile wait"), NULL, 0, 0);        mciSendString(_T("close OpenFile"), NULL, 0, 0);    }

C/C++ code

CString strPath("");MCI_OPEN_PARAMS mciOP;mciOP.lpstrDeviceType = NULL;mciOP.lpstrElementName = strPath;  // MP3文件所在路径DWORD dwReturn = mciSendCommand(NULL, MCI_OPEN, MCI_OPEN_ELEMENT | MCI_WAIT | MCI_OPEN_SHAREABLE, (DWORD)(LPVOID) &mciOP);MCIDEVICEID wID;if (dwReturn == 0){    wID = mciOP.wDeviceID;}else{    wID = NULL;}MCI_PLAY_PARMS mciPP;DWORD dw = mciSendCommand(wID, MCI_PLAY, MCI_NOTIFY, (DWORD)(LPVOID)&mciPP);
