The IErrorLog interface is an abstraction for an error log that is used to communicate detailed error information between a client and an object. The caller of the single interface method, AddError, simply logs an error where the error is an EXCEPINFO structure related to a specific property. The implementer of the interface is responsible for handling the error in whatever way it desires.
IErrorLog is used in the protocol between a client that implements IPropertyBag and an object that implements IPersistPropertyBag.
A container implements IErrorLog to provide a control with a means of logging errors when the control is loading its properties from the container-provided property bag.
A control logs calls the single method in this interface to log any errors that occur when it is loading its properties.
