Check String Control for Content

[jfherrm]

Hello! I am using Labview to communicate via GPIB. I would like to send a certain command only if a specific string control is empty. I was wondering if there is any basic or straightforward way to check if a front panel string control is either empty or if it has content? Thanks in advance!

"Empty string?" under comparison pallette.

Use a case strucure and wire the string to the selector. See example.

What would you like to do if the string is empty?
