Using Concatenate Strings to Build Strings

[SercoSteveB]

What are the values in String Out and String Length Out following execution of the VI?

a)      Starting String01234, 15

b)      Starting String12345, 20

c)      Starting String01234, 20

d)      Starting String01234, 21

its A

The answer is A

the fact that the string length is not modified by the loop means that it would be 15

Can u please post the picture in little large size .

I replaced the string constant with array of strings the LabVIEW throughs error? is that because ofI`ve connected to shift register insted of auto indexing terminal?

Hi gnshmrthy, thanks for participating and commenting.

The majority of the pictures should be VI Snippets (with the exception of those including implicit property nodes).  You should be able to drag it straight from your browser to the block diagram?

Let me know if this functionality is not working?

I think the error is due to the Concatenate Strings being incompatable with arrays.  It is valid to wire an array to a Shift Register but inside the loop you would need to use arrays compatable functional nodes.

Answer A:  Nice one ashwinilele and RS.

Key concepts are that the Iteration Count terminal begins at 0 and increments by 1 for each iteration and that the string length node is outside the loop so it is the length of the string constant "Starting String" is only calculated once (before the loop executes) and is passed to String length Out on completion of the loop.

What are you talking about when you say you can drag from the browser to the block diagram

Also what is the easiest way to put block diagram and front panel items in this blog?

I find the process of saving images and the inserting them tedious, and hesitate to do so

From my posts; the ones surrounded by the dotted line, with 2009 (the version of LabVIEW you are running) in the top right hand corner and some LabVIEW specific stuff in the top left hand corner, should be VI snippets.  Some of my posts are not snippets as VIs which contain implicit property nodes aren't recreated correctly but most posts are.

Check out VI Snippets here: https://decibel.ni.com/content/docs/DOC-7547

You should be able (LabVIEW compatibility version issues aside) to left click drag and drop a VI Snippet from your internet browser window to the Block Diagram of a VI in LabVIEW.  The block diagram of the snippet should be the same as if you'd wired it yourself.  Pretty cool eh?

I am not sure there is an easy way to put a block diagram inside a post, I think VI Snippets are the most useable for the end reader, as they are so much more than just a picture.  Each time I need to include a picture/VI; I am having to save a VI Snippet in LabVIEW and then browse to it, and insert image, from the blog posts.  It is pretty clunky, and annoyingly fails alot.

Hi Steve,

When I drag this snippet to block diagram,I am not getting the code,instead just a path is displayed.
