Show VI from another VI as a popup dialog

[gcsaba2]

Hi there,

I have a beginner question. I created a VI which displays some data, and I have an Edit button to edit the selected data. When I press the Edit button, I want to show another VI, preferrably as a modal dialog. How to do this?

Thanks, Csaba

1. go to vi properties (CTRL+I)

2.Select "window apprearence" from the "categoty" drop down list box

3.Hit the "customize" button

4.Put a check mark on "Show front panel when called", "Close afterwards if originally closed"

5.Select "Modal" radio button under "window behaviour"

6.Hit the OK button.

OK but how to display the second VI after a click the button? I tried making a case structure, and into True I've dragged the second VI. As a result I have the second VI appear/disappear every 100 ms (because the main VI is inside a while loop with a 100 ms delay). I thought that it would appear only when I click the button...

Do you have a button wired to the case structure? Remember that the button has to be inside the whileloop also. If you have done all this I think that you have the wrong mechanical action on your button. Right-click the button and select latch when released ( I think this is the correct one. I'm reinstalling LV now otherwise I would have given you an example). Correct me if I'm worng on the switch/latch thingy

That helped 🙂 By default it was Latch when pressed. I also had to add a While loop to the second VI, I somehow assumed that it will get included into the parent's while loop because it's a modal window.

I'm glad it worked out for you!
