DVASPECT
The DVASPECT
enumeration values specify the desired data or view aspect of the object when
drawing or getting data.
typedef enum tagDVASPECT
{
DVASPECT_CONTENT = 1,
DVASPECT_THUMBNAIL = 2,
DVASPECT_ICON = 4,
DVASPECT_DOCPRINT = 8
} DVASPECT;
Elements
DVASPECT_CONTENT
Provides a
representation of an object so it can be displayed as an embedded object inside
of a container. This value is typically specified for compound document
objects. The presentation can be provided for the screen or printer.
DVASPECT_THUMBNAIL
Provides a
thumbnail representation of an object so it can be displayed in a browsing
tool. The thumbnail is approximately a 120 by 120 pixel, 16-color (recommended)
device-independent bitmap potentially wrapped in a metafile.
DVASPECT_ICON
Provides an
iconic representation of an object.
DVASPECT_DOCPRINT
Provides a
representation of the object on the screen as though it were printed to a
printer using the Print command from the File menu. The described data may
represent a sequence of pages.
Remarks
Values of
this enumeration are used to define the dwAspect field of the FORMATETC structure. Only one DVASPECT
value can be used to specify a single presentation aspect in a FORMATETC
structure. The FORMATETC structure is used in many OLE functions and
interface methods that require information on data presentation.
