COM Interface Error Propagation from C++ to LV

I have found that only error codes that are <0 (msb bit
set) will propagate up to a LV error cluster from my automation interface.
Is it possible, in accordance with the COM spec, to be able to pass error
codes with a positive value up to LV?

Good question. All LabVIEW errors are negative, so it may be carrying over this generalization when dealing with your COM server. I'm not sure if this would be the case. This is really a question for LabVIEW experts though, so I would post the question to the LabVIEW section of Developer's Exchange here so LabVIEW users can respond.
