Search and replace string problems

[Igor Dzombic]

Hi to all,

I have problem with Search and replace string function. It shows me a wrong Value (Number) from 15 to 100 is everything OK (15=0, 30=1, 45=2, 100=3), but after 100 ........

Take look in VI and if you have any ideas post them please 🙂

THX

What is it that you're trying to do? What is your input string, and what are you expecting to get out? It appears that you are trying to do a substitution. If that's the case, one problem you have is that you need a shift register. Otherwise your output will simply be the same as if you have done only the very last substitution, and none of the ones before it. Also, you can replace the while loop with a for-loop. Also, if doing a substitution, are you intending to substitute all instances? If so, then you need to start with the longest string to search for first.

it`s like this: if the string same as one of the Numbers in column 1 the Value (Numeric) should be the same as the the Numer in column 2 (same row)..

Well, I pretty much figured that out from the code. But you still have not provided the string that you're actually feeding the VI, and what you expect the VI to provide. Also, my other query: is it supposed to replace all instances? For example, let's say the input string is "15115". Should the output be 10 or 4?

there will be no 15115 string, but 15 or 115 and 15 is 0, 115 is 4. Anyway, i have changed string input format and now its working 😉 THX for your help

I cant open your file as i've only got 8.2, but from your explanation i'd solve it like this:

String --> String to number --> (modula) Divide by 15 = index

Based on your latest VI it appears that you want to convert an hour:minute string to an index. It really would have helped if you had said this from the beginning, as there is a far easier way to do this:
