Windows 7 Development: Shell Library

2. Compile and test:

A. Open a command line window and switch the directory (CD) to the location where SLUtil.exe is located.

B. Open the Library shell folder next to the Command Line window and you will see the changes you have made using the Slutil tool.

C. In the Command Line window, test the Slutil command.

D. Try to use the same icon as the Pictures library for your Mylib library.

E. Try locking and unlocking your library in the file Management panel.

F. Change the default storage location of the library, move this location to another location in the file system, and test whether the default storage location resolves the change.

Task 6– Add foldertype command

Each library has a folder template type. This type defines the look and feel of the Shell Library window, for example, there are different templates for pictures and music. The Ishelllibrary Setfoldertype () method uses a GUID to represent the type ID of the folder. The Getfoldertype () method returns the ID of the current folder. By default, user-created libraries are general folder types.

In order for the user to use the text type instead of using a GUID, we need to use a Help class. Cfoldertypeidnameconverter This class knows how to convert pictures, Music, Documents, videos, and generic to the corresponding foldertypeid_*, and vice versa. At the same time, this method also knows to take a part of the name, such as vid is videos. These will make the type of the Settings Library folder simple: Slutil foldertype mylib doc

1. Add FolderTypeIdNameConverter.h and FolderTypeIdNameConverter.cpp files to the project. You can find them from the starter folder.

2. Add #include "FolderTypeIdNameConverter.h"

3. Add the following code fragment to implement the FolderType command:

C + + (SLUtil.cpp)

Set or get the library ' s folder template


void FolderType (const CCommand &command, const vector<pcwstr> &arguments)


{


ishelllibrary *shelllibrary = NULL;


HRESULT hr = S_OK;


Foldertypeid Foldertypeid;





Cfoldertypeidnameconverter Converter;





//show current Folder type


if (arguments.size () = 1)


　　　　　　　　　　　　　　　　 {


//open Library with Read permissions


ishelllibrary *shelllibrary =


openlibrary (L "FolderType", Argume Nts[0]);





hr = Shelllibrary->getfoldertype (&foldertypeid);


if (FAILED (HR))


　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 {


Wcerr <<


L "Foldertype:can ' t get the library ' s folder template."


<< Endl;


exit (5);


　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 }


wcout << L "Library" << arguments[0] << L ": Folder template is: "<< converter. Getfoldertypeidname (Foldertypeid) << Endl;


　　　　　　　　　　　　　　　　 }

　　　　　　　　　　　　　　　　 {

exit (6);

hr = Shelllibrary->setfoldertype (Foldertypeid);


if (FAILED (HR))


　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 {


Wcerr <<

<< Endl;


Exit (7);


　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 }


//commit the library changes


shelllibrary->commit ();


　　　　　　　　　　　　　　　　 }


if (shelllibrary!= NULL)


shelllibrary->release ();


}


COMMAND (L "FolderType",


L "Slutil foldertype libraryname [documents| pictures| music| videos| Generic] ",


L "Set or get the library ' s folder Template", L "Slutil mylib Documents", 1,
