getchar() in Labview 5.1

I am new to Labview and am looking for a function that will return a
character every a key is pressed. Is there such an animal or how does
one go about doing it in LV. I want to compare every keypress and do
some thing based on it.

Thanks

Go to the NI Developer Zone and you'll find a keyboard utility at Resource
Library>LabVIEW>User Interface>UI Programming.

somewhere there is a keyboard.llb library of functions that do what you are
looking to do. I do not know the keeper of the code. It might be NI.

You might see if this works for you...

In the speed menu (right-click menu) of the String control there is an
option called "Update Value while Typing." (LabView 6i)

I used it for a real-time text parser.

Good luck,
Bob

There are some keyboard VIs on the ftp site. I think they are in the LV31
directory.
