LV8.5 and .NET

Hi all,

 

I am using LV8.5. I am very frustrated by its ability interacting with .NET assembly. My colleague gives me a .NET DLL dealing with database. Surprisingly if I am opening a VI which has a "constructure node" inside referencing this DLL, then this VI is always broken, even though it was good before I saved it. Only if I open this VI from a project, it is ok.

 

The more painful problem happens when I want to use classic state machine. Normally shift register is used here. But if I put wire the reference from constructor node with the shift register, I always get error during run time. If I give up shift register, and directly wire them, then it is OK! It looks like "shift register" can't contain reference from "constructor node".

 

Does anybody have met similar problems as me?

 

Thanks.

The second problem has been solved after I read a post in this forum:
