    GetClipboardSequenceNumber
    The result returned by this API function increments whenever the content of the clipboard changes, including emptying the clipboard. For example, a single copy-paste operation in Excel, first clears the clipboard, and then adds data to it in N different formats. So before-and-after difference will be N+1.
