# ScriptStopFBlock Method - neoVI API

This method stops the execution of a specified function block within a script on a neoVI device.

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

```cpp
int _stdcall icsneoScriptStopFBlock(void * hObject, unsigned int iFunctionBlockIndex);
```

{% endtab %}

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

```vbnet
Public Declare Function icsneoScriptStopFBlock Lib “icsneo40.dll” (ByVal hObject As IntPtr, ByVal fb_index As UInt32) As Int32
```

{% endtab %}

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

```csharp
[DllImport(“icsneo40.dll”)] public static extern Int32 icsneoScriptStopFBlock(IntPtr hObject,UInt32 fb_index);
```

{% 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).

iFunctionBlockIndex

\[in] The index value of the function block to stop

**Return Values**

1 if the function succeeded. 0 if it failed for any reason. [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

NEOVI\_ERROR\_DLL\_SCRIPT\_INVALID\_FUNCBLOCK\_INDEX = 219

NEOVI\_ERROR\_DLL\_SCRIPT\_NO\_SCRIPT\_RUNNING = 226

**Remarks**

The script containing the specified function block must have been successfully downloaded to the neoVI using [LoadScript](/neovi-api/win32-api-overview-intrepidcs-api/deprecated-functions-overview-intrepidcs-api/coremini-script-interface-overview-intrepidcs-api/scriptload-method-intrepidcs-api.md). Execution of the script must have been started by [StartScript](/neovi-api/win32-api-overview-intrepidcs-api/deprecated-functions-overview-intrepidcs-api/coremini-script-interface-overview-intrepidcs-api/scriptstart-method-intrepidcs-api.md). Execution of the function block must have been started using [StartFBlock](/neovi-api/win32-api-overview-intrepidcs-api/deprecated-functions-overview-intrepidcs-api/coremini-script-interface-overview-intrepidcs-api/scriptstartfblock-method-intrepidcs-api.md). The valid index values for function blocks within a script can be found in the <mark style="color:orange;">cmvspy.vs3cmb.h</mark> file (Produced by Vehicle Spy.
