Presentation on Decisions Behind the Design

• events = public (external)
• queues = local (internal)
• easier to debug

• Advantages of events

  • broadcast
  • doesn't matter if there are listeners (1 or more) or not

    • one event queue per listener
    • no listener - no queue
  • events in same queue (1 event structure) can have different data types
  • errors are edit time
  • register/unregister at runtime

• hard to search strings
• easy to find VIs
• easy to show which VIs are available (API)

• test modules individually, outside application
• can sniff messages (also in .exe)
