Error 1055 @ Property Node (arg1)

Go to solution

Dear community,


i struggle to find a solution for the following problem for a while. May one of you can give me a hint, how to get this programm running.


I wanted to write a programm with that i can click on 4 points to calculate two lines and find the intersection.

Somehow the Error 1055 apears everytime i want to select points in the graph, which says: Object reference is invaild. 


But i linked the event structure aswell as the property node to the xy graph.

On top of that, the front panel freeze everytime i click in the graph whithout pushing the button to "click points". 


 Thanks in advanced for your help! 



(by the way, I use the LabView Version 2017)

You do not have a single cursor, but you are trying to set its position.

First add a cursor, for example, through the properties of the graph.
