| Member name | Value | Description | |
|---|---|---|---|
| First | 1 | When this bit is set, the iterator is positioned at the first item in the sequence. In this state, there are no items before the iterator so calling MoveToPrevious will produce an error. Note that 'First' does not imply the iterator is valid. | |
| End | 4 | When this bit is set, the iterator is positioned past the final item in the sequence and is invalid. In this state, calling MoveToNext or attempting to read item properties will produce an error. Moving to a valid item will validate the iterator. | |
| Invalid | 8 | When this bit is set, the iterator is not in a valid state. Attempting to read or write item properties of an invalid iterator will produce an error. Iterator attribute properties can still be read. |
Remarks
