怎么打开光驱的门呢？

[xcopy]

我用mciSendCommand(mciGetDeviceID("I:"), MCI_SET, MCI_SET_DOOR_OPEN, NULL);
怎么打不开，请帮忙！

[Terminator_wang]

mciSendString("Set cdAudio door open wait",NULL,0,NULL);
mciSendString("Set cdAudio door closed wait",NULL,0,NULL);
注：这个在Win98下面是可以的！

windows 2000下测试通过
void CMyDlg::OnOpenCD()
{
// TODO: Add your control notification handler code here

UINT wDeviceID;
DWORD dwReturn;
MCI_OPEN_PARMS mciOpenParms;

// Opens a CD audio device by specifying the device name.

mciOpenParms.lpstrDeviceType = "cdaudio";

if (dwReturn = mciSendCommand(NULL, MCI_OPEN, MCI_OPEN_TYPE,
(DWORD)(LPVOID) &mciOpenParms))
{
mciSendCommand(mciGetDeviceID("cdaudio"), MCI_SET, MCI_SET_DOOR_OPEN, NULL);
/* char szErrorBuf[MAXERRORLENGTH];
MessageBeep(MB_ICONEXCLAMATION);
if(mciGetErrorString(dwReturn, (LPSTR) szErrorBuf, MAXERRORLENGTH))
{
MessageBox(szErrorBuf, "MCI Error",
MB_ICONEXCLAMATION);
}
else
{
MessageBox("Unknown Error", "MCI Error",
MB_ICONEXCLAMATION);
}*/
}

// The device opened successfully; get the device ID.
wDeviceID = mciOpenParms.wDeviceID;

mciSendCommand(wDeviceID, MCI_SET, MCI_SET_DOOR_OPEN, NULL);
}

void CMyDlg::OnCloseCD()
{
mciSendCommand(mciGetDeviceID("cdaudio"),
MCI_SET, MCI_SET_DOOR_CLOSED, (DWORD)(LPVOID)&StatusParms);
}

芝麻开门

[redlark]

void CCDROMDlg::OnOut()
{
if(mciSendString("set cdaudio door open",NULL,0,NULL)!=0)
MessageBox("open error!");
}

void CCDROMDlg::OnClose()
{
if(mciSendString("set cdaudio door closed",NULL,0,NULL)!=0)
MessageBox("close error!");
}

98和2000下都可以通过

光驱本来就打不开
