multiple login but after it search for 1 wrong time, it wont search anymore

[kavierkoo]

As tittle, my code doesnt work if the first time is wrong or to be accurate after a wrong search, it wont able to search anymore. Below are my code, when i tried to remove the outside while loop  and run it  in countinously mode It work just fine but after i do it with while loop, it just dont work.

Try to run your code in 'Highlight Execution' mode (5th icon in the toolbar). This will help to understand how it executes. I suspect that you are trying to handle multiple 'Login' button clicks, but now the event structure executes just one time. Take a look at the 'event structure' help. Usually (not always) the event structure resides in a loop.

In the 'login' subVI, the first 'match regular expression' function including that feedback node is probably not exactly what you need. Just replace them with a 'trim whitespaces' function if you are trying to remove the 'line feed' from the input

The Match Regular Expression and feedback node in your subVI are actually clearing out your list.  You should just get rid of the feedback node so that you always have the full list.

After looking at the problem a little more, I think what you really want is something like this:

If something works correctly in "run continuously," but fails in the while loop you know you've coded it to work correctly once.  Run continuously starts the code over after it runs and continues to run it as if it were the first time, every time.  It looks like it's working correctly because it's always running the first iteration.  You can never test the second iteration doing this.

Right now, get into the habit of never using that button.  You've just found one, of the many, reasons it's bad to do so.

Sorry to ask but could i have the .vi file for the code? because i have no idea what is going on ><

That is a VI snippet.  Drag it to your desktop, then drag that file into your block diagram.
