DVASPECT Enumeration

Specifies the desired data or view aspect of the object when drawing or getting data.

Syntax

typedef enum tagDVASPECT {
  DVASPECT_CONTENT,
  DVASPECT_THUMBNAIL,
  DVASPECT_ICON,
  DVASPECT_DOCPRINT
} DVASPECT;

Constants

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 member 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.

The default value of MiscStatus is used if a subkey corresponding to the specified DVASPECT is not found. To set an OLE control, specify DVASPECT==1. This will cause the following to occur in the registry:

HKEY_CLASSES_ROOT\CLSID\ . . .
   MiscStatus = 1
