IMessengerContacts::_NewEnum property
[_NewEnum is no longer available for use as of Windows Vista. See Windows Messenger for more information.]
Enumerates the MessengerContact objects in a collection.
This property is read-only.
Syntax
HRESULT get__NewEnum(
[out, retval] IUnknown **ppUnknown
);
Property value
Return value. Address of a pointer to the IUnknown interface on the copy.
Error codes
Returns one of the following values.
| Name | Meaning |
|---|---|
|
Success. |
|
ppUnknown is a NULL pointer. |
|
Failed during copy. |
Remarks
_NewEnum returns a copy of the current collection object. It is a standard method in any collection object. This avoids problems if multiple users are accessing the same remote object and assures that objects in the collections will not change during a traverse of the list.
If this method is called while the client is offline, the returned object is a working copy from an object perspective. However, if the copy is obtained while the client is offline, the contact list will always have zero members and zero count. This should be avoided.
Note
This property is available for scripting languages.
