Collect External Event Args Activity


Collects arguments from an external event.

Inheritance Hierarchy:



This activity works with the Listen for External Event activity. When a listener has been set up, this activity collects the arguments returned by the event.

In the Workflow:

A workflow using these two activities may consist of a Listen for External Event activity that is set to listen for a tool in the toolbar being used.  The Collect External Event Args activity would then collect the name of tool used and send this information to a log file.
