The following code illustrates how to copy the first five seconds of a file and place it in the clipboard.

    USHORT          usDeviceID;
    MCI_EDIT_PARMS  mep;

    mep.hwndCallback = hwndMyWindow;
    mep.ulFrom = 0;
    mep.ulTo = 5000;

    mciSendCommand( usDeviceID,
                    MCI_COPY
                    MCI_NOTIFY | MCI_FROM | MCI_TO,
                    &mep,
                    0 );
