Called by an object containing a data source to transfer data to the object that implements this method.
HRESULT SetData( FORMATETC *pformatetc, STGMEDIUM *pmedium, BOOL fRelease );
A pointer to the FORMATETC structure defining the format used by the data object when interpreting the data contained in the storage medium.
A pointer to the STGMEDIUM structure defining the storage medium in which the data is being passed.
If TRUE, the data object called, which implements SetData, owns the storage medium after the call returns. This means it must free the medium after it has been used by calling the ReleaseStgMedium function. If FALSE, the caller retains ownership of the storage medium and the data object called uses the storage medium for the duration of the call only.
This method returns S_OK on success. Other possible values include the following.
||Invalid value for lindex; currently, only -1 is supported.|
||The value for pformatetc is not valid.|
||The tymed value is not valid.|
||The dwAspect value is not valid.|
||The object application is not running.|
||The operation failed.|
||An unexpected error has occurred.|
||The dwDirection value is not valid.|
||There was insufficient memory available for this operation.|
SetData allows another object to attempt to send data to the implementing data object. A data object implements this method if it supports receiving data from another object. If it does not support this, it should be implemented to return E_NOTIMPL.
The caller allocates the storage medium indicated by the pmedium parameter, in which the data is passed. The data object called does not take ownership of the data until it has successfully received it and no error code is returned. The value of the fRelease parameter indicates the ownership of the medium after the call returns. FALSE indicates the caller still owns the medium, and the data object only has the use of it during the call; TRUE indicates that the data object now owns it and must release it when it is no longer needed.
The type of medium specified in the pformatetc and pmedium parameters must be the same. For example, one cannot be a global handle and the other a stream.
