LVOOPs-Problem with object creation

[Ramya12]

Hi all,

I am new to LVOOPs and trying to figure out things. I have a parent class named "Vehicle" under which there is a "Bike" class. The Bike class has two children A and B. To each class A and B I created Object instances and upcasted them Using "To more generic functions" to vehicle class. Now I am not able to access any of the VIs under any class using this newly created object instance. Can anyone explain me why? being new to LVOOPS I find it difficult to understand this. Thanks for the help in advance.

Why are you using "to more generic" at all? It sounds like you messed that one up.

I assume that you are looking for dynamic dispatching. Please review the LVOOP examples for this.

You can only use VIs that the "wire" (aka class) knows about. If you up cast to a parent calss there has to be a VI in the parent class if you want to use that VI. Any VI (marked for dynamic dispatch) in a child class can over-ride the  same named VI of the parent.
