[app designer] Create callback function when a variable changed.
13 views (last 30 days)
Hello I am here to find help
I want to make a simple app which containing a Lamp in app designer.
That Lamp turns green when this app connected with other app by TCP/IP.
And when TCP/IP connection is disconnected, the Lamp turns to be red.
I think it is possible by some kind of callback function called when TCP/IP connection check value is changed.
How can I make it?
