DVASPECT (Compact 2013)
3/26/2014
This enumeration contains values that specify the desired data or view aspect of the object when drawing or getting data.
Syntax
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 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
