[app designer] Create callback function when a variable changed.

6 visualizzazioni (ultimi 30 giorni)
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?

@Jae-Hee Park - you might be able to use the ErrorOccurredFcn callback to capture if there is an error and from that you might be able to assume that the connection is lost. I couldn't see a function that might check the state of the connection. There might be one, but it wasn't obvious to me.
