Show a pop-up message like "About" message when user presses a button without stopping the VI

Hello, 

I think the title explains it all. Show a pop-up message like "About" message when user presses a button without stopping the VI

Hi idir,

when you want to run two things in parallel you need to program them in parallel!

In LabVIEW and its THINK DATAFLOW paradigm this translates into "without data dependencies"…

Use two parallel loops to handle both your button/dialog and the remaining parts of your VI!

I don't want to use two loops. Just one and it's a must. Is there any other way?

You can use the Asynchronous Call.

You should go ahead and create a VI that displays your about text and some buttons (like ok) and set it to have modal display properties (VI properties can be accessed by menu, or with the shortcut Ctrl-i, you in particular want it to open and close when it starts/stops) then use the Asynchronous Call node that Crossrulz mentioned.

A simple VI could be an Event Structure with an empty case for the value change event for the ok button, and a string indicator. Adding a string control to the connector pane, hiding it, and wiring it directly to the indicator (outside of the event structure) allows you to reuse the VI with other text too.
