I'm dealing with VB.NET and the PI-SDK.
I use the function PTPoint.Data.Summary(..) to get the average of a lot of pint for different timeranges.
In the most cases it works well, but sometimes a comexception occured.
I checked the root cause with Excel and Datalink.
The Datalink-Funktion shows the error code and text
Is there a solution to get the error code in the VB.NET too?
What's the preferred way to work with these type of function which do not delivere an error state?
