Multiple search 1D array elements

[AndreaD]

Just wondering, from a single array am I able to search for different elements?

[Kyle97330]

There are some "hidden" VIs in your <vi.lib> folder.  Try this one:

vi.lib\AdvancedString\Match 1D String Array.vi

Basically it combines "Search 1D array" from the array palette with the "Match Pattern" VI from the string palette.

So you can search for [5A][5A] or whatever pattern fulfills your searching needs.

Hi Kyle,

I can't seem to find where Advanced String folder is located. When I do a search, I can't find Match 1d String Array as well. Where is this located?

Thanks,

Andrea

If you look in VIPM (VI Package Manager), you will find a package called "Hidden Gems".  Install that package and you will see a new item in your palette exposing these functions that were mentioned.

For more information: Hidden Gems in vi.lib

I'm fairly certain that you don't actually need to install the "hidden gems" addon.  I checked 2 PCs with LV 2015 and LV 2011 installed on them, and both had the file mentioned in vi.lib already.  Neither had the addon installed via the package manager.

To clarify:

This VI is a National Instruments VI and is included with your LabVIEW install (unless you have a really old version...).

This VI is not in your palettes by default, which is probably why you can't find it.

Depending on your OS and installed version the actual location may be different, but for example you might find it here:

C:\Program Files (x86)\National Instruments\LabVIEW 2015\vi.lib\AdvancedString\Match 1D String Array.vi

Define what you mean by "different elements". It is not clear to me from the picture.

• Do you want to find one or the other (whatever comes first).
• Do you want to find the first instance of each?
• Does each occur multiple times and you want to find all of the locations?
• Does one of the always come first? (search for that one, then starting from the found index search for the second one)

Even without the mentioned subVI, it seem trivial to just autoindex over an array of search elements and do a "search array" on each. It can probably even be parallelized.

Definition of "different element" ... Just because 5A and A5 are in different orders, they're associated with different packets of data (not my choice of naming data packets, since it's so close, but it's from another engineer)

Somehow when reading the data, it reads 5A but not A5 ... Is it supposed to? Perhaps there just isn't the A5 data coming out?

Thanks,

Andrea

Could be a byte order thing. What does the string represent?

[AndreaD]

Those are values to two different packets of data (again, not my choice of packet definition, they're both way too close!!)

Here you can find the VI
