Infinite loop!


I have an issue, i can’t unterstand! I’ve a loop “do while” !

Which should get out of the result if it’s value out of the loop is equal nominal, but not it keeps looping…



Try this condition:

Not output_matches(0).Tostring.ToLower.Contains(“nominal”)



Thank you, could you please tell me why my condition didn’t work?

‘IsNot’ operator checks if two objects refer to different objects, but it doesn’t check values.

‘Not =’ operator checks if the value between the objects are different.

Since you’re checking if the value of the string is different (and NOT whether it’s the same object), you want to use Not = instead of IsNot.

Buddy @mz3bel
you were almost right
First let me tell you why you faced the error and what can be the alternative one
you mentioned the condition like
output_matches(0).ToString isNot "nominal"

it shoul be like this
output_matches(0).ToString isNot equal "nominal"

Try this condition buddy this would work as per your condition with very minor changes

@Palaniyappan - check out my explanation above. The IsNot operator should not be used in this circumstance because it is checking if the objects themselves are the same. We instead should use the = operator (combined with Not as we want it to not be equal) because we want to compare the VALUE of two distinct objects to see if they are the same


Thats great i know about the equal operator and that would work for sure
but i was wondering to use isnot here and check whether it will work or not
anyhow go to know now
Cheers buddy @Dave

Hi guys,

I run my process today to check it, i see i get the same issue as yesturday!

PS: i’m using " output_matches(0).Tostring.ToLower.Contains(“nominal”) " as mentioned as solution, because it worked yesturday! no changes have been made!

Also, used log, to see the result of that command, it gives me true, which means it does contain “nominal” ??

Thank you!
