IDBProperties is used to set and get the values of properties on the data source object or enumerator and to get information about all properties supported by the provider.
Before the data source object or enumerator is initialized, the consumer can work only with properties in the initialization property group. After the data source object or enumerator is initialized, the consumer can work with properties in the initialization, data source, and data source information property groups, although it cannot set the value of properties in the initialization property group.
Only properties in the initialization property group are guaranteed to survive uninitialization. That is, if the consumer uninitializes and reinitializes a data source object or enumerator, it might need to reset the values of properties in groups other than initialization.
IDBProperties is a mandatory interface for data source objects and an optional interface for enumerators. However, if an enumerator exposes IDBInitialize, it must expose IDBProperties.
| Method | Description |
| GetProperties | Returns the values of properties in the data source, data source information, and initialization property groups that are currently set on the data source object or the values of properties in the initialization property group that are currently set on the enumerator. |
| GetPropertyInfo | Returns information about all properties supported by the provider. |
| SetProperties | Sets properties in the data source and initialization property groups, for data source objects, or the initialization property group, for enumerators. |
Returns the values of properties in the data source, data source information, and initialization property groups that are currently set on the data source object, or the values of properties in the initialization property group that are currently set.
