IPropertyBag interface

Provides an object with a property bag in which the object can save its properties persistently.

Members

The IPropertyBag interface inherits from the IUnknown interface. IPropertyBag also has these types of members:

  • Methods

Methods

The IPropertyBag interface has these methods.

Method Description
Read

Tells the property bag to read the named property into a caller-initialized VARIANT.

Write

Tells the property bag to save the named property in a caller-initialized VARIANT.

 

Remarks

To read a property in IPersistPropertyBag::Load, the object calls IPropertyBag::Read. When the object saves properties in IPersistPropertyBag::Save, it calls IPropertyBag::Write. Each property is described with a name, whose value is stored in a VARIANT. This information allows a client to save the property values as text, for example; which is the primary reason why a client might choose to support IPersistPropertyBag.

The client records errors that occur during Read in the supplied error log.
