Change information in a table with combobox

[Mocte117]

Hello,

I'm trying to use a combo box with each month of the year. When I select a month, it need open a text file with the information of that month, the code must be the same for all the months, it only have to change which file must be opened. I have the problem that I can't change the information in the table when the VI is running. Selecting another option in the combo box does not change the information. Can anybody help me?

This is the code (I inserted a case for combo box to try to change the open file, but it is not working as I expected)

The files:

What I see from the picture is: You read the combo box and the file only once before the while loop. When the VI is running (in the while loop) the information can not be updated. 

You should create a 'Value Change' (or a 'Mouse Up') event in the event structure for the combo box, read the file in the event and update the array in the shift register.

Note: I can not see what is happening in the other cases of the event structure and I can not debug pictures.

We can't really work with pictures. if you want help, attach your VI and some typical data files. Your shift regsiter contains an array, and there are plenty of array operations that can be suitable, depending on what you want to do (replace, append, etc.).

This is the VI.

Your code only reads the ComboBox one time, at the beginning of execution.

Take all the code that is outside the loop and put it inside the event case "Combo Box": Value Change.

Update: It's fixed. There is an error when I try to save a modification, the VI opens a tab to manually save the file. But I can already see the list depending on the month 🙂

Of course you shouldn't expect anyone to help you with that because you haven't included your code.  You've just put up a picture, and your picture doesn't even show the part of the code that you're complaining about.  No one here is psychic.
