Boolean true/false for String Control

[NickIke1]

Hi All, 

Is there a simple way to determine if there are any characters populated into a string control?  For example, I would like to produce a boolean true if there are characters written in the string control, and false if the control is empty?

Thanks,

Nick

Try negating the output of "Empty String Path Filename?" on the Comparison pallet.

Perfect, thanks!

Also remember that string controls have a few more additional useful options such as "limit to single line" and "update value while typing".

By default, characters in a string control are not read by the code until the entry is finalized (clicking outside, hitting <enter> if set to "limit to single line", etc.).

If you set it to "update value while typing", you'll get a more instant response if programmed correctly.
