FORMATETC
This structure is a generalized clipboard format, enhanced to encompass a target device, the aspect, or view of the data, and a storage medium.
Syntax
typedef struct tagFORMATETC {
DWORD cfFormat;
DWORD ptd;
DWORD dwAspect;
LONG lindex;
DWORD tymed;
} FORMATETC;
Members
- cfFormat
Particular clipboard format of interest. The following three types of formats are recognized by OLE.- Standard interchange formats, such as CF_TEXT.
- Private application formats understood only by the application offering the format, or by other applications offering similar features.
- OLE formats, which are used to create linked or embedded objects.
- ptd
Pointer to a DVTARGETDEVICE structure containing information about the target device for which the data is being composed. A NULL value is used whenever the specified data format is independent of the target device or when the caller does not care what device is used. In the latter case, if the data requires a target device, the object should pick an appropriate default device (often the display for visual components). Data obtained from an object with a NULL target device, such as most metafiles, is independent of the target device. The resulting data is usually the same as it would be if the user chose the Save As command from the File menu and selected an interchange format. - dwAspect
Specifies one of the DVASPECT enumeration constants that indicate how much detail should be contained in the rendering. A single clipboard format can support multiple aspects or views of the object. Most data and presentation transfer and caching methods pass aspect information. For example, a caller might request an iconic picture of the object, using the metafile clipboard format to retrieve it. Note that only one DVASPECT value can be used in dwAspect. That is, dwAspect cannot be the result of a BOOLEAN OR operation on several DVASPECT values. - lindex
Part of the aspect when the data must be split across page boundaries. The most common value is –1, which identifies all of the data. For the aspects DVASPECT_THUMBNAIL and DVASPECT_ICON, lindex is ignored. - tymed
One of the TYMED enumeration constants which indicate the type of storage medium used to transfer the object data. Data can be transferred using whatever medium makes sense for the object. For example, data can be passed using global memory, a disk file, or structured storage objects. For more information, see the TYMED enumeration documentation on MSDN® Online.
Remarks
The FORMATETC structure is used by methods in the data transfer and presentation interfaces as a parameter specifying the data being transferred.
Windows CE does not support the CF_ENHMETAFILE or CF_METAFILEPICT values in the cfFormat member.
