I tried the following, 'NotificationFilter' data looks exactly
the same for 'Insert' or 'Remove'.

also, I did not know from where to take
'NotificationFilter.dbcc_classguid' data.

Thanks.



void __fastcall TForm1::WMDiskChange( TMessage &Message )
{
  DEV_BROADCAST_DEVICEINTERFACE NotificationFilter;
  char szMsg[80];

  ZeroMemory( &NotificationFilter, sizeof( NotificationFilter ) );

  NotificationFilter.dbcc_size        = sizeof( DEV_BROADCAST_DEVICEINTERFACE );
  NotificationFilter.dbcc_devicetype  = DBT_DEVTYP_DEVICEINTERFACE;
//NotificationFilter.dbcc_classguid   = InterfaceClassGuid;  // ? ? ? ? ?  

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