Заметки

If the data is in the persistent property set format, the default implementation modifies the control's state accordingly. Otherwise, the default implementation does nothing. If bRelease is TRUE, then a call to ReleaseStgMedium is made; otherwise not.

Override this function to replace the control's data with the specified data.

For more information, see the FORMATETC and STGMEDIUM structures in the Windows SDK.
