DVASPECT (Windows Embedded CE 6.0)

1/6/2010

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
