GetUpdateID
The GetUpdateID method returns an update ID identifying the current generation or version of this clipboard object.
ODUpdateID GetUpdateID ();
return value
The update ID of the current clipboard content.

DISCUSSION
Your part may call this method to check whether another part has changed the clipboard. The returned update ID uniquely identifies the current generation or version of the clipboard. Note that update ID values have no significance other than in the context of testing them for equality. Also, the update ID value returned by this method is valid only during the current session.
It is possible, but dangerous, to call this method before your part has acquired the clipboard focus.

IMPORTANT
Clipboard update IDs are used for a different purpose than are link and link-source update IDs. You should never set the update ID of a link-source object to an update ID returned by this method.
