[dan_u]

Yet another solution if you don't want to use OpenG:

thanks dan_u and _lan_ for your help any your solutions

Nice solutions, but is there any similar, simple methods for a 2D array?:)

Greetings

Sjefsgjogleren,

I would suggest you try to adapt that piece of code yourself. A second while loop would assist with the second dimension. However, it likely would need a few more small adjustments. Feel free to post your progress here and people will be more likely to assist.

This thread is 6 years old and solved. No need to attach an extremely inefficient solution that is also wrong. (For example it would output incorrect result if some rows contain empty and non-empty strings).

• Why would you operate on columns (you transpose at the beginning and end) if the task is about rows?
• Why would you need to measure the array size with every iteration of the outer loop? Wouldn't once be enough? The size does not change between iterations here (well, the compiler will probably optimizes this, but still ...)
• "delete from array" typically does not belong inside a tight loop.
• The inner loop iterates way too many times (# of empty strings << # of array elements).
• ....

Hello,

I've used your suggestion but...each time the vi run the Array is not erased and it's populated keeping previous results.

First run

Second run

Where is the mistake?

Thanks in advance

I add my vi.

Sorry,

I;ve solved the case.

Thanks to your multiple examples.

What suggestion? My suggestion is to use the "Quote" button from the toolbar to indicate what's the post you are referring.
I cannot open your vi, but I guess you are not initializing a shift register. An uninitialized sr retains its previous value, so running multiple times may end in concatenating the results.
