* Win32 Shell Folders |
|
42 |
* <P> |
|
43 |
* <BR> |
|
44 |
* There are two fundamental types of shell folders : file system folders |
|
45 |
* and non-file system folders. File system folders are relatively easy |
|
46 |
* to deal with. Non-file system folders are items such as My Computer, |
|
47 |
* Network Neighborhood, and the desktop. Some of these non-file system |
|
48 |
* folders have special values and properties. |
|
49 |
* <P> |
|
50 |
* <BR> |
|
51 |
* Win32 keeps two basic data structures for shell folders. The first |
|
52 |
* of these is called an ITEMIDLIST. Usually a pointer, called an |
|
53 |
* LPITEMIDLIST, or more frequently just "PIDL". This structure holds |
|
54 |
* a series of identifiers and can be either relative to the desktop |
|
55 |
* (an absolute PIDL), or relative to the shell folder that contains them. |
|
56 |
* Some Win32 functions can take absolute or relative PIDL values, and |
|
57 |
* others can only accept relative values. |
|
58 |
* <BR> |
|
59 |
* The second data structure is an IShellFolder COM interface. Using |
|
60 |
* this interface, one can enumerate the relative PIDLs in a shell |
|
61 |
* folder, get attributes, etc. |
|
62 |
* <BR> |
|
63 |
* All Win32ShellFolder2 objects which are folder types (even non-file |
|
64 |
* system folders) contain an IShellFolder object. Files are named in |
|
65 |
* directories via relative PIDLs. |
