Typically one good solution is sufficient. How many different "solutions" do you actually need? Have you tried any of the suggestions? Did you encounter any problems?

hi ,i add a refresh button to the database code . i want to know your opinion to my code  .

If it works as expected, then it is good. Do you want a code review? Does the code do what you expect? Are you having any problems? Have you tried all that was suggested? Please share code and not pictures.

- A button named "button"? Really?

- Use the event structure to trigger on the "refresh button" instead.

You cannot mix polling (the Boolean\case) with events!

Add a refresh value change event to the event structure. Put the refresh code in it. Put the result in a shift register.

Add an ID value change event to the event structure (remove it from the shared event with Button). Put the ID code in it, using the data from the shift register. 

Rename Button to Stop.

When done correctly, the refresh will refresh, the ID will update the name\brand\reference and Stop will stop.

hi , 

@thols  you find below my code ( button mean : Home button )

@ wiebe@CARYA  what do you mean by put the result in shift register (while loop + Shift Register or for loop +Shift Register ) more explantation please  .

I already described what to do long ago.

Your above code is completely useless. Why would you need a case structure if both cases contain identical code???

Here's one (of many!) possibility. You really should start with a few more LabVIEW tutorials!
