		The data object is returned in an any. The contained type may differ on

		@param aProcessId
		The argument aProcessId is a process identifier of the caller's process.		
		The interface implementation must ensure that the system data object can be
		used in that process. If the data object is not valid in the caller process
		then the returned any must be empty.

		@returns
		The system dependent data object.

		<br/><br/><p><strong>Notes:</strong>Under Windows the returned any contains an unsigned long which represents a pointer to
		an IDataObject interface. The caller of getData has to release the data
		object (IDataObject::Release) if it is no longer needed.
		The caller must also make sure that the current thread has been initialized for
		OLE (use OleInitialize).</p>
