Darren's Weekly Nugget 04/10/2006

[Darren]

This week's nugget pertains to a cool new feature in LabVIEW 8.0 that I just discovered last week.  The Format Into String function now allows you to specify a different order for the inputs to appear in the formatted string than the order you wire them into the function.  For example, if you had four strings wired into the Format Into String inputs, and your format string was "%s %s %s %s", then the output string would just be those four strings in the order they were wired.  But as you can see in the screenshot below, there is now a way to specify the order of the inputs in the format specifier.  In the example below, by using the "%n$s" specifier, where 'n' is the position of the wired input, you can dynamically change the position of inputs in the output string.  Try it out!

P.S. - Check out past nuggets here.

Hey, this is cool!!

Of course with a fixed format string as in the above example, we might as well wire the inputs in the desired final order. 😉

The new feature starts to shine once we generate or select the format string programmatically. 😄

This feature is indeed cool and I'll have to move to 8 be use it (if I can rmember it of course )

... but why does it start from 1 and not from 0 ??

If you look at the context help for Format Into String, you'll see that the input names are "input 1, input 2, ..., input n".  The format specifier is simply being consistent with the input names.

Ok, 1-0 for you Darren... I didn't see that...

I won't ask why input names start from 1 and not from 0

Nice to learn new features.

Maybe CC can use this to add more randomness and variety for his automated congrats tool.  Mixes up the messages as well as provide alternative bits of text..

Hey that's just cool.

"Small" changes like this can really simplify certain types of code.

I'm (still) looking forward to working with LV 8.....

cool one.

can think of quite a few creative uses of this feature!

[jwdz]

Ok!

LabVIEW 7.1?

Nice feature! Does it allow repeat and omission of inputs?
