# ISO15765\_ReceiveMessage Method - neoVI API

**This method configures a receive message using ISO15765-2 on a CAN network. icsneoISO15765\_EnableNetwroks must be called before using icsneoISO15765\_ReceiveMessage. PCI bytes and Flow control decoding is taken care of by the dll for the transaction.**

```cpp
void _stdcall icsneoISO15765_ReceiveMessage(void * hObject, unsigned long ulNetworkID,stCM_ISO157652_RxMessage *pMsg);
```

{% endtab %}

{% tab title="Visual Basic .NET Declare" %}

```vbnet
Public Declare Function icsneoISO15765_ReceiveMessage Lib “icsneo40.dll” (ByVal hObject As IntPtr, ByVal ulNetworkID As Integer, ByRef pMsg As stCM_ISO157652_RxMessage) As Int32
```

{% endtab %}

{% tab title="C# Declare" %}

```csharp
[DllImport(“icsneo40.dll”)] public static extern Int32 icsneoISO15765_ReceiveMessage(IntPtr hObject,Int32 ulNetworkID,ref stCM_ISO157652_RxMessage pMsg);
```

{% endtab %}
{% endtabs %}

**Parameters**

hObject

\[in] Handle which specifies the driver object created with the OpenPort method.

*ulIndex*\
\[in] Specifies the Index to configure, 10 elements 0-9.

stCM\_ISO157652\_RxMessage

\[in] This is the address of the [stCM\_ISO15765\_RxMessage](/neovi-api/win32-api-overview-intrepidcs-api/structures-types-and-defines-overview-intrepidcs-api/setting-structures-overview-intrepidcs-api/stcm_iso157652_rxmessage-structure.md) structure. The structure contains the properties for the multi frame message transaction.

**Return Values**

None.

**Remarks**

None.
