# SIMCONNECT_RECV_EVENT_OBJECT_ADDREMOVE<no value>
The **SIMCONNECT\_RECV\_EVENT\_OBJECT\_ADDREMOVE** structure is used to return the type and ID of an AI object that has been added or removed from the simulation, by any client.

 

##### Syntax

``` cpp
struct #SIMCONNECT_RECV_EVENT_OBJECT_ADDREMOVE : SIMCONNECT_RECV_EVENT {
    SIMCONNECT_SIMOBJECT_TYPE  eObjType;
    };
```

| `eObjType` | Specifies the type of object that was added or removed. One member of the [SIMCONNECT\_SIMOBJECT\_TYPE](simconnect-simobject-type/) enumeration. |

##### Remarks

 

This structure inherits the [`SIMCONNECT_RECV_EVENT`](simconnect-recv-event/) structure, which inherits the [`SIMCONNECT_RECV`](simconnect-recv/) structure, and is returned when the dwID parameter of [`SIMCONNECT_RECV`](simconnect-recv/) is set to [`SIMCONNECT_RECV_ID_EVENT_ADDREMOVE`](simconnect-recv-id/). A client can determine whether the object was added or removed from its own event ID that was provided as a parameter to the [SimConnect\_SubscribeToSystemEvent](../general/simconnect-subscribetosystemevent/) function.

 

The ID of the object added or removed is returned in the `dwData` parameter (a member of the `SIMCONNECT_RECV_EVENT` structure).
