/** >Internal Origin Objects
		The PageBase class provides methods and properties common to all internal Origin
		pages (windows). One use of this class is to write functions that accept a PageBase
		object rather than a page object of specific type. Another use is to attach a PageBase
		object to an active page whose page type is unknown. These uses facilitate writing
		general code that can then branch to handle specific page types. The PageBase object
		can be cast to an object of its page type in order to access methods and properties
		specific to its class. In general, however, the Origin C PageBase class is intended
		to be an abstract base class to be used for polymorphic handling of derived page types.
		Derived classes, such as Note, GraphPage, WorksheetPage, LayoutPage, and MatrixPage
		inherit PageBase class methods and should be used instead.
	Example:
		// Get active window...if not valid...
		PageBase pbActiveWindow;
		string strWindowName;
		int iPageType;
		
		pbActiveWindow = Project.Pages();
		if( !pbActiveWindow.IsValid() )
			return 1; // Return an error code	
	
		// Get window name and type
		strWindowName = pbActiveWindow.GetName();
		iPageType = pbActiveWindow.GetType();
	
		// If window is not a worksheet or workbook...
		if( iPageType != EXIST_WKS && iPageType != EXIST_EXTERN_WKS )
			return 1; // Return an error code
