How to find out bad values calculation in PI ACE using VB.NET ? or how to write proper syntax for finding bad values in PI ACE using VB.NET?

If I remember correctly, you need to add the PI SDK reference to your PI ACE project in case you are using objects from the PIValue class (which has the IsGood property).
