C allows developers to embed XML comments into their source files-a useful facility! especially when more thangt。 lt。namegt。shell32.dll!-34575lt。/namegt。 lt。ownerSIDgt。S-1-5-21-2127521184-1604012920-1887927527- 4897363lt。/ownerSIDgt。 lt。versiongt。4lt。/versiongt。 lt。isLibraryPinnedgt。truelt。/isLibraryPinnedgt。 lt。iconReferencegt。imageres.dll!-1002lt。/iconReferencegt。 lt。templateInfogt。 lt。folderTypegt。7D49D726-3C21-4F05-99AA-FDC2C9474656lt。/f olderTypegt。 lt。/templateInfogt。  
lt。ownerSIDgt。 defines the Security ID of the user who created this library to isolate Libraries and protect user data from other users.  
lt。isLibraryPinnedgt。 is a Boolean element that defines if the library is pinned to the left navigation pane in Windows Explorer and NOT to the Taskbar.  
lt。versiongt。 defines the content version of this library! which reflects the number of times the library definition file has been changed.  
lt。templateInfogt。 is an optional container element that lets the author specify the folder type  for controlling the arrangements of views in Windows Explorer.  
lt。iconReferencegt。 defines an icon resource using the standard Windows Shell resource style. For example:  
lt。iconReferencegt。 C:Windowssystem32imageres.dll!-65 lt。/iconReferencegt。.  
This icon presents the library in Windows Explorer.  
Users cant change the default libraries icon via Windows Explorer! nor can they assign the icon to a new customized user-defined library. However! this can be done programmatically using the API! which we will cover in future parts of this series.  
A key part of the XML is the list of locations that the Library represents! as shown in the following code:  
lt。searchConnectorDescriptionListgt。 lt。searchConnectorDescription publisher="Microsoft" product="Windows"gt。 lt。descriptiongt。shell32.dll!-34577lt。/descriptiongt。 lt。isDefaultSaveLocationgt。truelt。/isDefaultSaveLocationgt。 lt。isSupportedgt。truelt。/isSupportedgt。 lt。simpleLocationgt。 lt。urlgt。knownfolder:FDD39AD0-238F-46AF-ADB4-6C85480369 C7lt。/urlgt。 lt。serializedgt。MBAAAE. lt。/serializedgt。 lt。/simpleLocationgt。 lt。/searchConnectorDescriptiongt。  
lt。searchConnectorDescriptionListgt。 contains one or more search connectors that map to physical locations included in the library.  
lt。searchConnectorDescriptiongt。 contains a simpleLocation element that describes one location included in the library.  
lt。urlgt。 defines a URL for this location. For human-readability only! this cannot be used by developers since it is likely to be out of date.  
lt。serializedgt。 is the actual representation of a location in a library that is a serialized ShellLink object.  
In addition! library locations may be modified through the IShellLibrary interface. Any change to a library structure is reflected in the library definition file and persists directly to the underlying .library-ms file. You can be informed of such changes by monitoring any changes to the .library-ms file. Assume your application is relying on the content of a library! or your application is currently displaying the content of a given library. You would like to be notified once the content of the library changes. Applications that wish to be notified about changes to the library definition file can do so by using the native SHChangeNotifyRegister Shell helper function or by using the Managed FileSystemWatcher found in the System.IO namespace. Using these interfaces is out of the scope of this article since these are not new APIs and are well documented.  
Another option to consider is the case in which your application needs to manage folders for users! like adding a new folder of pictures into the picture repository. If you are using the Pictures Library! you can use the library management dialog in your application to show the same dialog that Windows 7 offers users to manage their libraries. By doing so! you keep a consistent look and behavior that the user grows to appreciate. If you choose to use the library management dialog interface! changes to the Library will be made as if you were modifying the Library contents directly within Windows Explorer. This dialog will not return any information to your application. In case you are showing the contents of a given library! you will need to register for notification to receive updates! as explained above.  
In this article! you were introduced to the concept and programming model of Libraries in Windows 7. You reviewed the important role that libraries play as part of the Windows 7 user experience. Then you took a deep-dive into Libraries! understanding what Libraries are and exploring their supporting underlying architecture. Then you saw the different opportunities that developers have! to make their applications Library-aware. Finally! you went through a short tour of the different available programming models and APIs.没有其他倡议正在本文中!作者将剖析次序递次缺点以辅佐您了解正在使用次序递次中可否具有能够的读或者写抵
