Exceptions

Exception	Description
System.ArgumentNullException	A `null` reference (`Nothing` in Visual Basic) is passed to a method that does not accept it as a valid argument. This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.
System.InvalidOperationException	A method call was invalid for the object's current state. This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.
OpcLabs.BaseLib.Licensing.LicensingException	The component is not licensed for the operation requested.
System.ObjectDisposedException	An operation was performed on a disposed object.

Remarks

The "Read" operation reads a value of a point and stores it into the binding source. Only bindings of type PointBinding that include PointBindingOperations.Read in their BindingOperations are affected; other bindings are ignored.
