MB,
please follow the info in this KB:
http://digital.ni.com/public.nsf/allkb/22BF02003B4588808625717F003ECD67?OpenDocument
Please note that using "By Value" will never return any values to TestStand!
You cannot use the default error-container in TestStand to receive data from the LV error cluster if you compile the VI into a LV DLL.
So either you choose to follow the KB or you split up the error cluster in your LV VIs to return error.occurred (boolean), error.code (numeric i32) and error.msg (LV String) .
hope this helps,
Norbert
