Simple Input Sample

Download sample

This sample illustrates the use of queues to send data into a workflow. It demonstrates the use of four API calls that are required to send data into a workflow using a WorkflowQueue object.

  1. The sample includes a custom activity that creates a named queue, subscribes to an event that indicates when a queue item is available, and dequeues an item from the queue. The host application contains the code that enqueues the item.

The test workflow is written to use the custom activity in a loop. The workflow will keep dequeuing items (which are assumed to be strings) until it finds the string "exit", at which point the loop and the workflow end.
