Where are you passing the reading the value returned from your c# code in labview? Implementation details: Assertions are handled by a custom ZMQ_ASSERT macro (err.hpp) which is implemented (err.cpp) on Windows as a RaiseException Win32 API call. The root cause of the error will be related to the.NET Exception Message, as 1172 is a generic error code for any.NET Exception. In LabVIEW 8.0 and later, more information was added to the error messages by placing the.NET Exception Message property into the error source string in the error cluster. When you create an Array constant on the block diagram, it is not visible on the Front Panel. This reusable toolkit includes the VIs shown below, which DMC developers use to efficiently incorporate alarm handling in a wide variety of LabVIEW applications.
