# SetFireSettings Method - neoVI API

This method writes configuration settings to a neoVI Fire device.

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

```cpp
int _stdcall icsneoSetFireSettings(void * hObject, SFireSettings *pSettings, int iNumBytes, int bSaveToEEPROM);
```

{% endtab %}

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

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

{% endtab %}

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

```csharp
[DllImport(“icsneo40.dll”)] public static extern Int32 icsneoSetFireSettings(IntPtr hObject, ref SFireSettings 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

\[out] Pointer to an [SFireSettings](/neovi-api/win32-api-overview-intrepidcs-api/structures-types-and-defines-overview-intrepidcs-api/setting-structures-overview-intrepidcs-api/sfiresettings-structure.md) structure.

iNumBytes

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

bSaveToEEPROM

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

**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 [SFireSettings](/neovi-api/win32-api-overview-intrepidcs-api/structures-types-and-defines-overview-intrepidcs-api/setting-structures-overview-intrepidcs-api/sfiresettings-structure.md) structure must be initialized with the current neoVI settings using [GetFireSettings](/neovi-api/win32-api-overview-intrepidcs-api/device-settings-functions-overview-intrepidcs-api/neovi-fire-intrepidcs-api/getfiresettings-method-intrepidcs-api.md).
