how can i convert a large hex (bigger then U64) string to a number

[žabić]

I cannot find this function in the array pallete

What function are you referring to, and which code are you referring to? You also have to clarify the format of your source string. I.e., whether you have hex values, or ASCII letters. 

To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.

That is the Build Array primitive from the Array palette.  You really should consider the tutorials smercurio_fc recommended.

This almost solves my problem 🙂 

Since my string updates 3 times in a second (in a while loop) I need to figure out how to display all of the data, and not just the current value. I tried to use Build Table Express VI, but it requires a numeric input, and I can't convert such a large HEX string to a number.

Hey Zabic,

What was the problem with the solution from smercurio_fc's

the function that you were unable to find is just a build array VI from the array pallate.

I found that, but as I said, my string is in a while loop, and I need to display it every time a loop executes, but string from the last execution must not be erased. Every time a loop executes, I need to write a string to a new row.

Can you try something like this??

Build Array in a loop like this is a very dangerous thing to do. It will accumulate indefinitely as long as the loop executes and since there is no thing like unlimited resources, be it memory or anything else, it will come to a grinding halt at some point.

Yes Rolf, i think you are right. I am scratching my head to find the alternative solution for the problem. Or even programmer should take care of such pitfalls and try to avoid it.

In this case I think programmer can limit the size of the array to be displayed in table and delete all the previous data from the array. Please let me know if there is any alternative method to do it.

Thanks again for the Point Rolf.
