要#include "mmsystem.h"


先定義全局變量﹕
UINT wDeviceID;
MCI_OPEN_PARMS mciOpenParms;
MCI_PLAY_PARMS mciPlayParms;
MCI_STATUS_PARMS mciStatusParms;
CString path="c:\\test.mid";

然后可以寫以下代碼循環播放﹕
mciOpenParms.lpstrDeviceType = "sequencer";
mciOpenParms.lpstrElementName = path;
mciSendCommand(NULL, MCI_OPEN,
MCI_OPEN_TYPE | MCI_OPEN_ELEMENT,
(DWORD)(LPVOID) &mciOpenParms);
wDeviceID = mciOpenParms.wDeviceID;
mciStatusParms.dwItem = MCI_SEQ_STATUS_PORT;
mciSendCommand(wDeviceID, MCI_STATUS,
MCI_STATUS_ITEM, (DWORD)(LPVOID) &mciStatusParms);
mciPlayParms.dwCallback = (DWORD) this->GetSafeHwnd();
mciSendCommand(wDeviceID, MCI_PLAY, MCI_NOTIFY,
(DWORD)(LPVOID) &mciPlayParms);

不行啊

ActiveMovie控件，在菜单中依次选择"project- >Add To Project- >Components And Controls"，结合定时器应该可以满足你的要求，循环播放。

我用这个方法播放MIDI

但无法循环播放。

没有这个消息
case MM_MCINOTIFY:

midi.Replay();

break;

不行啊~~~没收到消息

[a_melon]

mciPlayParms.dwCallback = (DWORD) hwnd;

hwnd 是正确的吗?

[kakalong]

主要是收不到 MM_MCINOTIFY
