I tried the following initialisation code:

HDEVNOTIFY hDevNotify;
DEV_BROADCAST_VOLUME NotificationFilter;

memset( &NotificationFilter, 0, sizeof(NotificationFilter) );

NotificationFilter.dbcv_size = sizeof(DEV_BROADCAST_VOLUME);
NotificationFilter.dbcv_devicetype = DBT_DEVTYP_VOLUME;
NotificationFilter.dbcv_unitmask=0x0f;
NotificationFilter.dbcv_flags=DBTF_MEDIA;

hDevNotify = RegisterDeviceNotification( Application->Handle,
                                                &NotificationFilter,
                                                DEVICE_NOTIFY_WINDOW_HANDLE);

However the RegisterDeviceNotification() fails with error code 13, which I 
believe is "Invalid Data".  What am I doing wrong?

Thanks,
MikeW
