you need to apply some kind of sorting!
IF text="router" THEN add entry to first listbox IF text="endnode" THEN add entry to second listbox
Instead of "listbox" you surely work with string arrays…
I made the logic but I am not able to remove the blank spaces in outout listbox.Kindly plz help.
Use shift registers to avoid blank spaces. If you use default tunnels in case structures it will add default values in the output array.
The attached VI might help you.
