Provides a sample project with code to open and/or close a CD or DVD drive drawer.

This project demonstrates how to open and close a CD or DVD drive drawer. It also works on the new Blu-ray drive I got recently.


I needed a way to open and/or close a drive drawer without regard to whether or not the drawer was already open or closed. This sounds easy, but most of the ways of doing this I tried (like using the MCI library) and I had problems determining whether or not the drawer was open or closed. Using this code, I just tell it what I want it to do. If it's already open, it stays open; if it's closed, it stays closed.

Using the code

There is nothing fancy in this code. Users can simply cut and paste the code needed from this sample into their own projects. This uses a fairly simple IOCTL call. Note: the function returns whether or not the call worked, but this is not necessarily the result the caller intended. For example, most notebook computers will report that a drive is closed, but the drive must be closed manually. Programmers can get around this by detecting that the disc is not ready in the drive.

// Opens or closes the CD or DVD drive specified in drive letter.
bool COpenCloseCDDlg::OpenCloseTray(bool bOpen, TCHAR cDrive)
    // Open the device (drive) that we want to affect
    CString cs;
    HANDLE hDrive = CreateFile(cs, GENERIC_READ, FILE_SHARE_READ, 
                               NULL, OPEN_EXISTING, 

    // Make sure the device was found and opened successfully
    if(hDrive == INVALID_HANDLE_VALUE || GetLastError() != NO_ERROR)
        return false;

    BOOL bStatus; // Let the caller know if it worked or not
    DWORD dwDummy; // We don't really need this info
    if(bOpen) // Open the tray
        bStatus = DeviceIoControl(hDrive, IOCTL_STORAGE_EJECT_MEDIA, NULL, 
                                  0, NULL, 0, &dwDummy, NULL);
    else // Close the tray
        bStatus = DeviceIoControl(hDrive, IOCTL_STORAGE_LOAD_MEDIA, 
                                  NULL, 0, NULL, 0, &dwDummy, NULL);
    return bStatus?true:false;
