reverse string but not esc'd special chars?

[John Lokanis]

Before I go and reinvent another wheel, does anyone have a VI that will reverse a string but not esc'd chars in the string?

For example, if my string is:

find \[this\] text

and I want to find it by searching from the end of my data first, I reverse it and the data before using match pattern. But the reverse is this:

txet ]/siht[\ dnif

what I need is this:

txet \]siht\[ dnif

because I need to preserve the esc'd special chars in the search string so match pattern works.

thanks for any help!

upload it then

you can import the snippet into LabVIEW and run it.

And how do I do that?.

Drag the image to your block diagram, (if using 2010).

2009. I just get a hyperlink. But I'm beyond caring now .

You need to save it to disk first, then drag on diagram. It works on LV2009 too.

I think it has to do with Firefox (or maybe the way LAVA deals with pictures?) because I've dragged them directly to diagram before. Don't sure what has changed since I did that.

Google's the same.

I think IE is the only one to work directly?

OK. so really we are just talking performance here.

So with this as the seed. What's the execution time?

Do people still use that?

I hate it too (but am forced to use it occasionally).

I'm a Google Chrome man, its so fast - esp download images on screen etc... I love it.

If it is all about performance, how about this;

I haven't played with regular expressions in a while, but maybe there is a way to do this with Match Regular Expression.

Yup. that's my solution too. Except I just used the value d92 instead of a cast

Always nice to hear that others think the same

For clarity I prefer to use the cast, and because of constant folding I believe that there will be no hit in performance.

Indeed. It confirms my suspicion that I'm really not as stupid as I look

Can't argue with that. Readability over elegance (no performance hit). But in contrast to your previous statement. computers definitely don't think like me.

thanks for the improvement ideas. I will give them a try. Perhaps this would make a good addition to the OpenG string functions?
