DISCLAIMER: I renounce all responsibility for any headaches which may be caused by the number of hashtags in the below example.
Have you ever seen a piece of writing and thought "that'd make an amazing hashtag?" #labview #awesome #WhyDoesItTakeSoLongToWriteHashtagsLikeThis?
Fear not, the #HashtagVI is here!
Simply copy and paste any piece of text into the string control and it will turn it into #YourOwnPersonalHashtagFormattedLikeThis
If you press the "Turn on Twitter Truncation" button, it'll even limit your hashtag to a length of 140 characters with a handy ellipse at the end for you!
You could also see this as a handy example of the interchangeability of strings and byte arrays and how to manipulate both.
Notes: Made with LabVIEW 2013. Made purely for entertainment, and the front panel looks like that because I like bright colours.
