This code is being used in Excel 2019 64 bit to get the range of the cells on the clipboard as opposed to the contents of the cells.
fGetClipRange returns a range object for the Excel range that is cut or copied onto the clipboard, including book and sheet. It reads it directly from the clipboard using the "Link" format, and requires the ID number for this format. The ID associated with the registered formats can change, so fGetFormatId finds the current format ID from a format name. Use Application.CutCopyMode to determine whether the cells were cut or copied.
