Going back to the original question - I have had a bit of a dig and found this on TMP:
"According to Nosworthy, "The Anatomy of Victory", p.42, Louis XIV introduced the use of socket bayonet in all regiments with a circular of November 11, 1692. Moreover he records at p.43 that Villars was allowed to remove pikes from the Army of Italy from January 16, 1702. However shortage of flintlocks prevented the full elimination of pikes until 1708."
