# SetFire2Settings Method - neoVI API

{% tabs %}
{% tab title="C/C++ Declare" %}

```cpp
int _stdcall icsneoSetFire2Settings(void * hObject, SFIRE2Settings *pSettings, int iNumBytes, int bSaveToEEPROM);
```

{% endtab %}

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

```vbnet
Public Declare Function icsneoSetFire2SettingsLib “icsneo40.dll” (ByVal hObject As IntPtr, ByRef pSettings As SFIRE2Settings, ByVal iNumBytes As Int32, ByVal bSaveToEEPROM As Int32) As Int32
```

{% endtab %}

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

```csharp
[DllImport(“icsneo40.dll”)] public static extern Int32 icsneoSetFire2Settings(IntPtr hObject, ref SFIRE2Settings pSettings, Int32 iNumBytes, Int32 bSaveToEEPROM);
```

{% endtab %}
{% endtabs %}

**Parameters**

hObject

\[in] Specifies the driver object created by [OpenNeoDevice](/neovi-api/win32-api-overview-intrepidcs-api/basic-functions-overview-intrepidcs-api/openneodevice-method-intrepidcs-api.md).

pSettings

\[in] The address of an allocated [SFIRE2Settings](/neovi-api/win32-api-overview-intrepidcs-api/structures-types-and-defines-overview-intrepidcs-api/setting-structures-overview-intrepidcs-api/sfire2settings-structure.md) structure.

iNumBytes

\[in] This value is always the size, in bytes, of the [SFIRE2Settings](/neovi-api/win32-api-overview-intrepidcs-api/structures-types-and-defines-overview-intrepidcs-api/setting-structures-overview-intrepidcs-api/sfire2settings-structure.md) structure.

bSaveToEEPROM

\[in] If set to 0, the settings changes will revert to the values stored in EEPROM when the neoVI FIRE 2 is power-cycled. If set to 1, the values will overwrite the EEPROM settings and become persistent across power-cycles of the neoVI FIRE 2.

**Return Values**

Returns 1 if successful, 0 if an error occurred. [GetLastAPIError](/neovi-api/win32-api-overview-intrepidcs-api/error-functions-overview-intrepidcs-api/getlastapierror-method-intrepidcs-api.md) must be called to obtain the specific error. The errors that can be generated by this function are:

NEOVI\_ERROR\_DLL\_NEOVI\_NO\_RESPONSE = 75

**Remarks**

Before using this function, the [SFIRE2Settings](/neovi-api/win32-api-overview-intrepidcs-api/structures-types-and-defines-overview-intrepidcs-api/setting-structures-overview-intrepidcs-api/sfire2settings-structure.md) structure must be initialized with the current neoVI settings using [GetFIRE2Settings](/neovi-api/win32-api-overview-intrepidcs-api/device-settings-functions-overview-intrepidcs-api/neovi-fire-2-intrepidcs-api/getfire2settings-method-intrepidcs-api.md).
