search and replace pattern (string) not -1 when not found

[kdCMC]

Hey,

when using the 'search and replace pattern' for string with input string "0" searching for ".", past offset output returns 1 (and not -1).

Hi kd,

it always helps to provide an example VI to demonstrate the problem:

So what's the problem?

Btw. as there is no "search and replace pattern" I took SearchAndReplaceString instead…

Hey Gerd,

I assume Your example is not from NXG environment, but lv2017 or earlier.

I have attached a snapshot of my screen now.

thx & regards,

Koen.

I'm going to take a guess that you're using Match Pattern and passed in "." instead of "\.".

"." is a special character for regex matching so it needs to be escaped.
