Thanks for the hint with the exception information. Lucky for me, I'm helping develop the .NET library. So I'll see what can be done about adding a "last error" property.
But LabVIEW support for this library is more for the OEM testing departments, while C# and VB interface is meant for the production code. So while LV support is important, I don't know how much the guidelines can be bent since C# and VB are the larger audiences. I don't think it will be traumatic (still unfortunate though) to add the last error property. Finding a way to access the default accessors is the more critical item today. (I know you're on the road and won't be able to get back to answering this right away.)
Thanks again for the help.
