How to turn a string sentence into words with indicators?

[askjdhvl]

Hi G Liagre!
Thank you for your reply!

I have tried to create a new program after your first solution!
Which is similar to your second one, of coz your solution is more better.

I have one more question, when my input string is empty, it show an error message and stop my program.

Which is "Error 1 occurred at Scan From String (arg 1)"

and

"Possible reason(s):

LabVIEW: An input parameter is invalid.
---
NI-488: Command requires GPIB Controller to be Controller in Charge."

What's wrong with the Scan From String???

Hi LV_Pro!
Thank you for your reply!

The points that you consider is very important!
Your suggestion is great!

And I am going to tell you kindly, my input string includes fixed four units only.

I have to appreciate again for your concerns.

Hi askjdhvl,

The error in the "scan string" when the string is empty is normal, because the input string is... empty (so it is declared invalid)!
If you want to avoid this error message, you can put a "switch case" which will inhibate the "scan string" when the input string is empty.

Best Regards,
G Liagre

I was about to post a new thread when I came accross this topic. Truly this place is the most technologically knowledgeable forum I have ever been a member of. I am working on a VI to manipulate strings, and will post when finished. I hope it helps someone else who is trying to learn.

That really a completely different animal and has nothing to do with this thread.  You should start a new thread.  You might be able to use something like the Microsoft Speech Agent.

I would recommend you search the forums for "speech recognition" and "speech agent".
