Property Value

Setting this property to true has effect only when the current process is running in user interactive mode.

The actual user interaction controlled by this parameters is performed by a code in OPC UA Configuration Library. As such, it does not have the same visual appearance and behavior as user interface provided by the component itself. Specifically, the dialogs do not have timeouts associated with them. This means that the current activity can be blocked for extended periods of time, or even indefinitely.

The situations in which the user interaction controlled by this parameters are quite rare. Following dialogs or message boxes can appear when this parameter is set to true:

• Any errors encountered while loading the SDK application configuration (this does not normally happen, because the SDK application configuration is pre-loaded by the component).
• User confirmation required to update the application instance certificate when the key size in the current certificate is less than the required minimum key size.
• Only for application that are not just OPC UA clients, but also OPC UA servers: User confirmation required to update the application instance certificate when the server is configured to use a domain which does not appear in the current certificate.
• User confirmation required to update the application instance certificate when the current certificate does not specify the application URI.
