Hi Chris, 
Thank for the reply. 
I am using TestStand 4.2 and LabVIEW 2009 SP1. 
Obviously I wanted to use the dynamic dispatch functionality. but I am kind stuck in the initial stage itself . 
When I inserted a LabVIEW Action step type with a code module having a Class as output, I am getting the properties as shown below. 
 
Now I am not sure how do I pass this Parent Class Out to a different code module. As this type is shown as Unknown, I am not able to pass this to a variable also. 
parden me if this issue is very silly, but some how I am stuck here. 
Looking forward to here form you, 
Mirash
