error

[sonnyanderson]

Hello,

I have built on the image below a Labview Program, which returns after a false comparison when you press ok and true when you not press ok.
it's a matter of comparing the value of the input and output.
values are differente when you press ok.
the problem is the following:
  how to get a system error when the comparison returns a false

Do you actually mean to set a LabVIEW error? That's simple. Use the Bundle by Name with an Error Constant as the input cluster.

On the Dialog and User Interface Palette, there is the "Error Cluster from Error Code" function.  If you wire a number other than 0 (= No Error) in to the (required) Error Code terminal, you will generate an Error with that number.  Note that many numbers already have LabVIEW errors associated with them.  Errors in the range 5000-9999 (and a few other ranges) are "User-defined Error Codes", meaning they are whatever you say they are.
