Hello,
I need to use the same instance of a .NET DLL within LabVIEW calls inside Teststand and a GUI (VI which will later become an executable) which is hosting the TS Engine.
Due to some .NET framework issues I cannot explain exactly, the .NET reference needs to be wrapped inside a LabVIEW class object. Now passing that LV object between LabVIEW VI's through Teststand via the connector pane and a StationGlobal does work.
Since LabVIEW development system and Teststand are different processes, I'd expect it to be possible to use the same instance of a DLL in different App Domains. Although I am not an expert on that topic.
In order to pass it to the GUI, I suppose I need to use the Teststand API.
I have tried a lot of stuff, like GetValInterface, GetValVariant or as the ActiveXParam of PostUIMessageEx.
Also tried to create it using SetValInterface and then accessing it with GetValInterface.
But whatever I am trying, the resulting refnum is 0000 / NotARefnum.
What is the way to access/pass the initialized .NET reference within the LV class object using the Teststand API?
Thanks for any help,
Stefan
