closing multiple vis

[Aojha]

I am designing a vi which opens various subVI front panel during run time. every subvi is opening different ports (Com or ehternet) on PC. I want to close all the vis by clicking the window close, andure that every port has been closed by the program before exiting

Handle the port close in Panel close event of event structure in each Sub VI

Hi Sc,

use a global "stop" flag. All subVIs will look at that flag and will close their ports (and windows) before exiting...

Can you tell me, How to generate panel close event of sub vi from main VI or any other vi.

hi GerdW.

Your solution will work. But I have some more problem. I have been asked to design vi like standard window application, where user should not press stop but will click on window close button. Again user may close every opened sub VI during run time and reopen again, till the main program is closed.

Hi Sc,

when asking for help it is always a good idea to present as much information as possible...

Use the panel close event in each (sub)VI as mentioned before!

HI everyone,

I think I got the solution.

I will use stop flag as suggested by GerdW.

and same time use panel close for individual vi's as suggested by nijams.

Thanks to both of you.
