| Platform SDK: Active Directory, ADSI, and Directory Services |
The members of a group are stored in a multi-valued property called member. The group membership may potentially contain a large number of values. This can be inconvenient or even impossible when the number of values in a multi-valued attribute becomes very large.
Active Directory supports incremental retrievals for this purpose. You may specify the range specifiers for multi-valued properties.
Range specifiers for a property take the following form:
attributename;Range=range
where attributename is the ldapDisplayName of the attribute and range is the range of values that you want to retrieve from the property. The * wildcard can be used to specify "to the end of the list" and 0 is used to specify the first entry in the list.
The following table contains examples of range specifiers.
| Example | Meaning |
|---|---|
| Member;Range=0-500 | Retrieve entries from 0 to 500 inclusively. The maximum potential entries are 501 values. |
| Member;Range=2-3 | Retrieve the 3rd and 4th entries. |
| Member;Range=501-* | Retrieve the 502nd entry and beyond. |
IDirectorySearch, IDirectoryObject, and ADO support range retrievals.
