I have created an XControl that has several custom properties and want to handle changes to the various properties differently from one another. How do I determine which property caused the Display State Change event to fire in the Fascade VI?
What you could do is add a string field to the state ability. In every property you write some identifier string to this field. In the facade VI you can easily read it out.
I have just tried it. Using strings occurred to slow the XControl beyond belief.
I have changed the strings to Enum.
Now performance is still disastrous, but definitely 5 to 10 times less slow, I still do not know if the only reason is the additional Control ID property.
