OOPS concept in Labview thru GOOP

[Rajus]

hi
actually we are tryng to implement OOP's concept in Labview thru GOOP.
while implementing the above concepts these are the steps we followed.,
1)First we created class A having int i variable with get and set methods.
2)In new vi let it be main.vi we instantiating the class A and setting the varialbe i thru setI method.
3)Finally we are storing the reference in a Global variable.
4)In another main2.vi,we are calling the refernce from the global variable,and trying to call getI method in class A.
5)we are getting the refernce with i value for the first time, and for the rest of the time the value of i is zero.


could anybody help us out.

Rajus,

Usually, you can think of refnums as a "pointers" to a reference and when stored in global variable, LabVIEW may update the reference without updating the global thus explaining the fact that you get a zero value the rest of the time.
