DESCRIPTION:

This class inherits from CBaseFolder for a base ShellFolder implementation

|
of IShellFolder and overrides methods to give Ftp Specific features.

CFtpFolder
|
||
|
|
|
||
|
|
The stuff that tracks the state of a folder.
|
||
|
|
|
||
|
|
The cBusy field tracks how many sub-objects have been created
|
||
|
|
(e.g., IEnumIDList) which still contain references to this
|
||
|
|
folder's identity. You cannot change the folder's identity
|
||
|
|
(via IPersistFolder::Initialize) while there are outstanding
|
||
|
|
subobjects.
|
||
|
|
|
||
|
|
The number of cBusy's never exceeds the number of cRef's, because
|
||
|
|
each subobject that requires the folder identity must retain a
|
||
|
|
reference to the folder itself. That way, the folder won't be
|
||
|
|
Release()d while the identity is still needed.
