IRunnableObject (Compact 2013)

3/26/2014

This interface enables a container to control the running of its embedded objects. In the case of an object implemented with a local server, calling IRunnableObject::Run launches the server's .exe file. In the case of an object implemented with an in-process server, calling the Run method causes the object .DLL file to transition into the running state.

When to Implement

Object handlers should implement IRunnableObject to provide their containers with a way to run them and manage their running state. DLL object applications should implement IRunnableObject to support silent updates of their objects.

When to Use

Containers call IRunnableObject to determine if an embedded object is running, to force an object to run, to lock an object into the running state, or to inform an object handler whether its object is being run as either a simple embedding or as a link source.
