// Version History:
//
// Version 2 - 01-May-2002
// =======================
// Produced new version with changes as below:
// * removed CBS_SORT on creation if specified
// * added option to allow the sort style to be set if required
// * fixed SetMaxHistoryItems, so it removes old entries from the list to 
//   ensure that there are no more than the maximum. Also made SaveHistory
//   remove redundant profile entries above the maximum.
// * use WriteProfileString to remove profile entries rather than CRegKey.
//
// Version 1 - 12-Apr-2001
// =======================
// Initial version
//
