/* A SUMINFO variable is an instance of an abstract data type. Thus,
|
||
|
|
** there can be an arbitrary number of SummaryInfo streams open
|
||
|
|
** simultaneously (subject to available memory). Each variable must
|
||
|
|
** be initialized prior to use by calling Init and freed after its
|
||
|
|
** last use by calling Free. The param argument to Init is reserved
|
||
|
|
** for future expansion and should be zero initially. Once a SUMINFO
|
||
|
|
** variable is allocated (by Init), the user can call the Set
|
||
|
|
** procedures to initialize fields. A copy of the arguments is made
|
||
|
|
** in every case except SetThumbnail where control of the storage
|
||
|
|
** occupied by the METAFILEPICT is merely transferred. When the
|
||
|
|
** Free routine is called, all storage will be deallocated including
|
||
|
|
** that of the thumbnail. The arguments to SetThumbNail and the
|
||
|
|
** return values from GetThumbNail correspond to the OLE2.0 spec.
|
||
|
|
** Note that on input, the thumbnail is read on demand but all the
|
||
|
|
** other properties are pre-loaded. The thumbnail is manipulated as
|
||
|
|
** a windows handle to a METAFILEPICT structure, which in turn
|
||
|
|
** contains a handle to the METAFILE. The transferClip argument on
|
||
|
|
** GetThumbNail, when set to true, transfers responsibility for
|
||
|
|
** storage management of the thumbnail to the caller; that is, after
|
||
|
|
** Free has been called, the handle is still valid. Clear can be
|
||
|
|
** used to free storage for all the properties but then you must
|
||
|
|
** call Read to load them again. All the code is based on FAR
|
||
|
|
** pointers.
|
||
|
|
** CoInitialize MUST be called PRIOR to calling OleStdInitSummaryInfo.
|
||
|
|
** Memory is allocated using the currently active IMalloc*
|
||
|
|
** allocator (as is returned by call CoGetMalloc(MEMCTX_TASK) ).
|
||
|
|
**
|
||
|

||
|
|
** Read SummaryInfo
