IPublishingWizard interface (shobjidl.h)
Exposes methods for working with the Online Print Wizard, the Web Publishing Wizard, and the Add Network Place Wizard. In Windows Vista, IPublishingWizard no longer supports the Web Publishing Wizard or Online Print Wizard.
Inheritance
The IPublishingWizard interface inherits from IWizardExtension. IPublishingWizard also has these types of members:
Methods
The IPublishingWizard interface has these methods.
| IPublishingWizard::GetTransferManifest Gets a transfer manifest for a file transfer operation performed by a publishing wizard, such as the Online Print Wizard or the Add Network Place Wizard. |
| IPublishingWizard::Initialize Initializes the Publishing Wizard object with the files to transfer, the settings to use, and the type of wizard to create. |
Remarks
The Online Print Wizard is a wizard for ordering prints of photos online. The use of IPublishingWizard to work with the Online Print Wizard is no longer supported in Windows Vista.
The Add Network Place Wizard allows the user to create a shortcut to network resources in My Network Places (in Windows XP) or Computer (in Windows Vista).
The Windows Shell supplies a Publishing Wizard object that implements IPublishingWizard and IWizardExtension. The methods of IPublishingWizard are used to initialize the type of the wizard, set certain attributes of the wizard, and retrieve a transfer manifest. The methods of IWizardExtension are used to retrieve the extension pages that make up the body of the selected wizard. To instantiate the Publishing Wizard object, call CoCreateInstance and use the class identifier (CLSID) CLSID_PublishingWizard and IID_IPublishingWizard as the REFIID.
IPublishingWizard *pPublish = NULL;
HRESULT hr = CoCreateInstance(CLSID_PublishingWizard,
NULL,
CLSCTX_INPROC_SERVER,
IID_IPublishingWizard,
(LPVOID*)&pPublish);
Once the Publishing Wizard object has been instantiated, call IPublishingWizard::Initialize to initialize the Publishing Wizard object.
// Initializing the Online Print Wizard
hr = pPublish->Initialize(pDataObject,
SHPWHF_NOFILESELECTOR,
L"InternetPhotoPrinting");
// pDataObject: A data object that represents files or folders to transfer.
// SHPWHF_NOFILESELECTOR: This flag must be set.
// L"InternetPhotoPrinting": Display the Online Print Wizard.
Note that IPublishingWizard::Initialize does not actually display the wizard. In order to display the Online Print Wizard, you must create a PROPSHEETHEADER structure and then modify its phpage member to include the array of PROPSHEETPAGE handles returned by IWizardExtension::AddPages. IWizardExtension::AddPages is implemented by the same Publishing Wizard object that implements IPublishingWizard.
If displaying the Online Print Wizard, the PSH_NOMARGIN flag should be set in the dwFlags member of the PROPSHEETHEADER structure that contains the extension pages.
In addition to the extension pages retrieved from IWizardExtension::AddPages, the phpage array should include a start page, a cancel page, and a finish page, provided by your application. When the user backs out of or cancels the extension, or when the extension finishes displaying its pages, the extension then communicates to the wizard that it must navigate out of the stack of extension pages to one of these application-provided pages. Your application must supply an implementation of IWizardSite that handles this communication. The IPublishingWizard object's site must be set to your IWizardSite implementation. The IUnknown_SetSite function can be used to set the site. Once your application has specified the wizard settings using IPublishingWizard::Initialize, properly populated the phpage member of a PROPSHEETHEADER structure, and set the site to an implementation of IWizardSite, the wizard may be displayed by calling the PropertySheet function.
/* This is example code demonstrating how to populate a PROPSHEETHEADER
structure and use it to display the Online Print Wizard.
This sample assumes that the PublishingWizard object has already
been instantiated and initialized elsewhere in the application. */
