Is there an easy way to replace individual elements in one string array from another striing array?

[chuck72352]

I have a string array with elements as follows:

   00 00 00 00 00 00 00 00

   00 00 00 00 00 00 00 00

   00 00 00 00 5E 00 00 00

   00 00 50 00 30 00 33 00

   34 00 39 00 00 00 00 00

   00 00 00 00 00 00 00 00

   00 00 00 00 00 00 00 00

The array I want to use to replace values with is:

43 4E 31 30 30 33 30 30 31 41

Where 43 goes in the 3rd row fifth position

Where 4E goes in the 3rd row seventh position

Where 31 goes in the 4th row  first position

Where 30 goes in the 4th row third position

Where 30 goes in the 4th row fifth position

Where 33 goes in the 4th row seventh position

Where 30 goes in the 5th row  first position

Where 30 goes in the 5th row third position

Where 31 goes in the 5th row fifth position

Where 41 goes in the 5th row seventh position

So the final array looks as follows:

   00 00 00 00 00 00 00 00

   00 00 00 00 00 00 00 00

   00 00 00 00 43 00 4E 00

   31 00 30 00 30 00 33 00

   30 00 30 00 31 00 41 00

   00 00 00 00 00 00 00 00

   00 00 00 00 00 00 00 00

Is there an easy way to replace an element of a string within an array with another element of a string within a different array?

Thank you.

Have you tried the 'replace array subset' vi? This lets you replace rows, columns or specific elements etc in array

[chuck72352]

With the replace array subset I was only able to replace an entire row in my array, not just a single element.

[chuck72352]

I've attached the concept for one approach, but it seems like there should be a better method.

Not true. Re-read the documentation on that function.

Now try to re-write your VI...

[chuck72352]

My array is 1D, which I believe means each row is a single element. If I understand the documentation correctly for the "replace array subset", I can only replace an element, not a portion of a single element.

For example in my array, a single element might be:   01 02 03 04 05 06 07 08. Therefore I could replace it with 01 01 01 01 01 01 01 01 for example, but I dont see a way to for example change only the 03 to for example 0A without replacing the element with 01 02 0A 04 05 06 07 08.

You might find it simpler to convert to a 2D array (which is the way you have your situation drawn).  Using "Spreadsheet String to Array" with the delimiter set to [space] will make this easier.  With a 2D array you could do the replacements easily.  Otherwise you'll need to extract one line of your array, use Replace Substring to replace just the characters you want, and finally put the modified string back into the array.

Nathand,

Thank you, that's kind of what I thought, I was hoping that there might be a better approach.

It's not quite working. Output array 2 has blanks in the positions where characters are expected.
