Increasing an array and making a drop-down menu

Question

Hi everyone,
I would like to do two things:
1.  After scaning tag IDs from an RFID reader from a serial port and individually entering them into an array (using auto-indexing), I get a n x 1 array (where n is the number of iterations, or rows).  Everytime I scan an entry in, I would like to add two things:  the temperature it was scanned at, and the time it was scanned at.  I am getting the temperature from the serial port, and am getting the time stamp using LabVIEW.  This would then make the array a n x 3 array. 
2.  The second thing I would like to do may sound simple.  I would like to make the n x 3 array I scanned in a drop-down menu.  It need not have the temperature and time appended to it, but it needs to have the tag IDs.  I am only doing this to convserve space on the PDA screen. 
I am attaching a sample file of what I am currently working on.  The "Read String" field represents the tag ID's i'll be reading.  It'll be in ASCII.
I'll appreciate any help
Thank you!

Answer 1

1. Simply make a 1D array of your 3 elements first (using "built array" with three inputs) inside the loop, then make it into a 2D array (e.g. at the loop boundary using autoindexing. You can also built it after the loop as in the image below.
2. Actually, you're not getting a "n x 1" 2D array, but a simple 1D aray of size N. You could for example feed it to a "strings[]" property of a ring control.

LabVIEW Champion . Do more with less code and in less time .
