IOleCache::InitCache method

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

Syntax

HRESULT InitCache(
  [in] IDataObject *pDataObject
);

Parameters

pDataObject [in]

A pointer to the IDataObject interface on the data object from which the cache is to be initialized.

Return value

This method returns S_OK on success. Other possible return values include the following.

Remarks

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 InitCache.
