Property Value

The value of this property can be null (Nothing in Visual Basic).

The default value of this property is null.

The EventData property contains an OpcLabs.EasyOpc.AlarmsAndEvents.AEEventData object for regular event notifications, and for notifications triggered by subscription refresh (except for RefreshComplete notification).

The EventData property contains a null reference when an error occurred (indicating connection loss; an Exception property is filled in this case), when a connection is re-gained (an Exception property contains a null reference in this case), or when the notification indicates that subscription refresh is complete (RefreshComplete property contains True in this case).

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
