IErrorLog
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.
When to Implement
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.
When to Use
A control
logs calls the single method in this interface to log any errors that occur
when it is loading its properties.
