Trigger event only after Enter key pressed (or barcode scanned)

[TanWal]

Hi,

I am trying to do the following....I have a string field where the user either manually enters a code or scans the code into it. Based on this code I want to trigger an event that will look at what this (string) code is and output another string (esssentially using a  case sequence in an event). Using Value change achieves what I want if I were only to enter in one value but I need to be able to do this with more than one value. any help in how to approach this would be appreciated. I am using Labview 8.2

Thanks!!

Without any actual code, I can only guess at what's wrong.

Is your event structure inside a while loop?

Does your string control have 'Update value while typing' active (I would advise you not to do so).

TanWal:

If you right-click your string control, is the "Update Value While Typing" option enabled? You may need to disable that to prevent the value change event from firing until the entire string is entered.

Also, if you enable "Limit value to single line," that will make the "enter" key submit the value instead of adding a new line (which will fire the value change event if you have "update while typing" disabled.

Thanks for the feedback, I wasn't aware of that option. It now allows me to control it better using the 'value change' event

Thanks for the solution, but TCPlomp had the idea first. You might want to mark his post as the solution instead
