Component Interface Reference

---

The following interfaces are relevant to components hosted by Microsoft® Internet Explorer. This section describes these interfaces.

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.
IObjectSafety	The IObjectSafety interface provides methods to retrieve and set safety options.
IObjectWithSite	IObjectWithSite provides simple objects with a lightweight (lighter than IOleObject) siting mechanism.
IPersistHistory	The IPersistHistory interface provides a mechanism for a component to persist its state within its containing application during the current session.
IPersistMemory	The IPersistMemory interface saves and loads objects from a stream.
IPersistPropertyBag	The IPersistPropertyBag interface works in conjunction with IPropertyBag and IErrorLog to define an individual property-based persistence mechanism.
IPersistPropertyBag2	The IPersistPropertyBag2 interface works in conjunction with the IPropertyBag2 and IErrorLog interfaces to define an individual property-based persistence mechanism.
IPropertyBag	The IPropertyBag interface provides an object with a property bag in which the object can persistently save its properties.
IPropertyBag2	The IPropertyBag2 interface provides an object with a property bag in which the object can persistently save its properties.
IServiceProvider	The IServiceProvider interface is a generic access mechanism to locate a GUID-identified service.

Remarks

A property bag is an object that holds information that is to be saved and restored across invocations of an object.
