Exposes a standard set of methods used to enumerate the pointers to item identifier lists (PIDLs) of the items in a Shell folder. When a folder's IShellFolder::EnumObjects method is called, it creates an enumeration object and passes a pointer to the object's IEnumIDList interface back to the calling application.
The IEnumIDList interface inherits from the IUnknown interface. IEnumIDList also has these types of members:
The IEnumIDList interface has these methods.
|IEnumIDList::Clone||Creates a new item enumeration object with the same contents and state as the current one.|
|IEnumIDList::Next||Retrieves the specified number of item identifiers in the enumeration sequence and advances the current position by the number of items retrieved.|
|IEnumIDList::Reset||Returns to the beginning of the enumeration sequence.|
|IEnumIDList::Skip||Skips the specified number of elements in the enumeration sequence.|
All Shell folder objects must be able to respond to a call to their IShellFolder::EnumObjects method by creating an enumeration object that exports IEnumIDList. The Shell, in particular, uses these objects to enumerate the items in a folder.
Use this interface to enumerate the contents of a Shell folder object. Call the folder's IShellFolder::EnumObjects method and use the returned IEnumIDList pointer to enumerate the PIDLs of the items in the folder.
