that is an enumerated constant it is found on the numerics palette

VKEY is the key you are comparing to or what have you...

you can get to it by left clicking on the rectangle.

What is its importance

[Harold_Timmis]

well in you example it is used to compare what key was pressed so that you get a read out of true or false so if I hit the up key the up led is set to true due to the VKEY being = to up

so it is important

Hi, I tried implementing your example. I'm trying to use the keyboard to control boolean buttons to make my "throttle bar" move up and down. It works, but I can't get it to switch until release when I hold down on my keyboard. My stop and clear buttons also doesn't seem to work when I put in the event structure.

I'm a total newbie. Help!

Hi saiko,

when you're a "total newbie" you should at first go through all those free online LabVIEW courses offered by www.NI.com!

Try this:

---

My stop and clear buttons also doesn't seem to work when I put in the event structure.

---

How did you configure the event case? When putting those buttons inside the event structure you have the tell that structure how/when to handle them. Did I mention the free online courses?

---

but I can't get it to switch until release when I hold down on my keyboard.

Do you want to use the automatic key press repeat feature? Well, you have to configure the event: right now it's "key press", but you probably want an event like "key repeat"? You may read the LabVIEW help on available events...
