Public Methods

Name	Description
IPropertyPageImpl::Activate	Creates the dialog box window for the property page.
IPropertyPageImpl::Apply	Applies current property page values to the underlying objects specified through SetObjects. The ATL implementation returns S_OK.
IPropertyPageImpl::Deactivate	Destroys the window created with Activate.
IPropertyPageImpl::GetPageInfo	Retrieves information about the property page.
IPropertyPageImpl::Help	Invokes Windows help for the property page.
IPropertyPageImpl::IsPageDirty	Indicates whether the property page has changed since it was activated.
IPropertyPageImpl::Move	Positions and resizes the property page dialog box.
IPropertyPageImpl::SetDirty	Flags the property page's state as changed or unchanged.
IPropertyPageImpl::SetObjects	Provides an array of IUnknown pointers for the objects associated with the property page. These objects receive the current property page values through a call to Apply.
IPropertyPageImpl::SetPageSite	Provides the property page with an IPropertyPageSite pointer, through which the property page communicates with the property frame.
IPropertyPageImpl::Show	Makes the property page dialog box visible or invisible.
IPropertyPageImpl::TranslateAccelerator	Processes a specified keystroke.

Public Data Members

Name	Description
IPropertyPageImpl::m_bDirty	Specifies whether the property page's state has changed.
IPropertyPageImpl::m_dwDocString	Stores the resource identifier associated with the text string describing the property page.
IPropertyPageImpl::m_dwHelpContext	Stores the context identifier for the help topic associated with the property page.
IPropertyPageImpl::m_dwHelpFile	Stores the resource identifier associated with the name of the help file describing the property page.
IPropertyPageImpl::m_dwTitle	Stores the resource identifier associated with the text string that appears in the tab for the property page.
IPropertyPageImpl::m_nObjects	Stores the number of objects associated with the property page.
IPropertyPageImpl::m_pPageSite	Points to the IPropertyPageSite interface through which the property page communicates with the property frame.
IPropertyPageImpl::m_ppUnk	Points to an array of IUnknown pointers to the objects associated with the property page.
IPropertyPageImpl::m_size	Stores the height and width of the property page's dialog box, in pixels.

Remarks

The IPropertyPage interface allows an object to manage a particular property page within a property sheet. Class IPropertyPageImpl provides a default implementation of this interface and implements IUnknown by sending information to the dump device in debug builds.
