Accessing elements in a large array without manipulating all the array

[tomasl]

Hi,

I have a large 2D array of strings (let's say 2x1000000). When i need to access only a few elements of the array it takes quite a lot of time. Is there anything to access those elements directly without manipulating all the array? (something like pointers in C++).

Thank You very much.

T.

Can you post some code so that we can see HOW you're doing it?

Try the In Place Element Structure to modify a single element of an array efficient. Array Subset and Replace Array Subset can also be efficient when used correctly.

An array of strings in LabVIEW is basically an array of pointers to strings; since strings are not fixed-size they cannot be stored in the array itself and so the array stores pointers to strings instead. String manipulation is often slow because the string may need to be reallocated as it grows.
