**Parameters**

hObject

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

bActivate

\[in] Specifies the state of the Activation line. True enables the activation and False disabled it.

{
    MessageBox.Show("Problem setting DoIP Act");
}
```
