- 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.
