A Library-aware application should include mechanisms for handling situations where users inadvertently try to pick Libraries as if they are folders for either saving files to a Library or loading the contents of a Library. Furthermore, most applications allow users to interact with the file system as part of the application experience.
An application should provide users with the same familiar entry points and UI offered by the Windows 7 Libraries. By including folders in a Library, users designate where their important data is stored, telling us this is the content they care about.
Applications should promote these locations by supporting Libraries in their application. For developers, there are several integration points with Windows 7 that can help applications become Library-aware.
Developers should review the following three integration points and select according to their needs. The good news is that Windows 7 Libraries are a first class citizen in the CFD, allowing users to browse through and search libraries.
They can even pick a specific library as a save location that is not just one of the folders from within the library, but rather the library itself! Because Windows 7 Libraries are storage-backed, users can save and copy files to any folder they have permissions for that are included in a Library.
Every Library has a default save location where files go when users copy and save files directly to the Library. By default, this location will be the known folder that is included in a default Library, or the first folder added to a custom Library. But there is always this caveat! However, the legacy version of the CFD doesn't directly support Libraries or the full new user experience offered in Windows 7. Figure 2 displays the legacy and the new CFD side by side. In the legacy CFD, even if Libraries are presented in the right navigation pane, they require an extra click to save into one of the included folders, rather than just the Library itself.
Users can neither search directly from within the CFD or experience the rich preview handlers, nor select multiple files across folders, because the legacy CFD doesn't support returning multiple files from different folder locations. In contrast, this is a scenario that a Windows 7 Library supports. When it comes to showing a CFD using.
NET, developers can either use the System. FileDialog or the Microsoft. FileDialog namespace. Since the latter uses the legacy version of the CFD,. Figure 3 shows a code snippet that prompts the user to choose a save location by showing the common save file dialog, enabling the user to select folders or libraries. This code tells the Open dialog to enable the user to select folders rather than files and allows the user to choose a Library as a save location.
In the case of choosing a Library, the CFD will then return the default save location folder that is associated with the chosen Library. Figure 3 and Figure 4 are very simple and don't introduce any new code. However, it is important to promote consistency among applications running on Windows 7 and in support of Windows 7 Libraries.
In most cases, it is the ideal way for users to browse and interact with Libraries from inside the application. Let's imagine a case of a slideshow application that presents pictures to the user.
By using Libraries, the user is essentially telling the system that his or her important pictures are stored in the Picture Library. The application can simply point directly to the Pictures Library and show the entire collection of pictures to the user. Furthermore, from the point of view of the developer, using the Library system can eliminate the need to maintain a separate configuration file or database of pictures, for example, since developers can rely on the Library System.
Items are individual, self-contained content sources. For example, quite a few of the interface methods used for controlling CFDs use Shell items to refer to folders instead of file system paths.
This is important because the CFD can communicate information about both file system folders and other virtual folders that you find in the Shell, such as the Control Panel or the Computer Folder. Now that we have defined the different components of the Shell Programming Model, we can see how Libraries fit into this model. Instead, you have two main options to consume the contents of a Library.
You can use the IShellItem and IShellFolder interfaces and a number of helper functions to enumerate the contents of Libraries, just as if they were regular folders. This means that applications can consume the content of a Library without using the new Libraries API and with very little change to their existing codebase.
Figure 5 shows how to use the IShellFolder interface to enumerate the entire contents of the Picture Library. There's also an uninstall registry script provided just in case. How to Disable "Libraries" Feature in Windows 7? The A. Instead of clicking through a bunch of directories to find the files you need, including them in a library makes for quicker access. To access the libraries in Windows 7, type libraries into the search box in the Start Menu and hit Enter. What if you have documents stored in a folder other than My Documents?
You need to add it to the Documents Library. There are a couple of ways you can go about it. Right-click on a folder and select Include in library from the context menu, then choose the Documents Library. Or when you have the folder containing your documents open, select Include in library and choose the library to put them in from the dropdown.
Here we take a look at the Documents library that contains files that are located in different places throughout the hard drive, including some on another partition. You can also remove items from libraries as well. While in the libraries directory click on the New library button and give it a name. In this example we made a new library called Work Projects. Not all folders can be added to libraries as Microsoft has stuck some rules on them. You can pretty much add anything from a local drive, including other volumes or partitions.
Win7 Library Tool is small and straight forward to use. Just click on the Create a new library button. Then add the network location you want included in the library. Notice this tool will also allow you to easily change the library icon which is a neat additional feature.
This should help get you started using Libraries in Windows 7, which at first might take some getting used to. How about you? Do you use libraries in Windows 7?
