IOleCache::InitCache

Fills the cache as needed using the data provided by the specified data object.

HRESULT InitCache(
  IDataObject * pDataObject  //Pointer to the data object from which 
                             // the cache is initialized
);

Parameter

pDataObject: [in] Pointer to the IDataObject interface on the data object from which the cache is to be initialized.

Return Values

This method supports the standard return values E_INVALIDARG and E_OUTOFMEMORY, as well as the following:

S_OK: The cache was filled using the data provided.
OLE_E_NOTRUNNING: The cache is not running.
CACHE_E_NOCACHE_UPDATED: None of the caches were updated.
CACHE_S_SOMECACHES_NOTUPDATED: Only some of the existing caches were updated.

Remarks

IOleCache::InitCache is usually used when creating an object from a drag-and-drop operation or from a clipboard paste operation. It fills the cache as needed with presentation data from all the data formats provided by the data object provided on the clipboard or in the drag-and-drop operation. Helper functions like OleCreateFromData or OleCreateLinkFromData call this method when needed. If a container does not use these helper functions to create compound document objects, it can use IOleCache::Cache to set up the cache entries which are then filled by IOleCache::InitCache.
