mciSendString 占用句柄

[nowordwind]

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．

	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);
	}

这不是被你搞死了么？

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);

这是我的一个测试程序．加入断点后，来看是不是有资源泄露，我的重点，是不要有句柄的增加，别外你的方法我试试，只要不引起内存泄露即可．

[nowordwind]

		CString strPath("D:\\AA.mp3");
		MCI_OPEN_PARMS 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_WAIT, (DWORD)(LPVOID)&mciPP);
		
		mciSendCommand(wID, MCI_CLOSE, NULL, NULL);

改成一楼的方法，只是改了API函数的不同后，一样的有句柄的增加，继续顶．
