IPropertyStore interface

Exposes methods for enumerating, getting, and setting property values.

Members

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

• Methods

Methods

The IPropertyStore interface has these methods.

Remarks

These methods can be called at any time after initialization of the property handler but before property changes are written to the file through IPropertyStore::Commit. At any other time, these methods return E_FAIL.

When to Implement

An implementation of this interface is provided by CLSID_InMemoryPropertyStore, as IPropertyStoreCache. Users should never need to implement it themselves.

CLSID_InMemoryPropertyStore implements IPropertyStoreCache instead of IPropertyStore so that it can store additional state information (PSC_STATE) about each of the properties in the cache. This information can be useful for property handler implementers. It can also be useful in other scenarios where a cache of property values is needed.
