' Class:    cRegistry
' Author:   Steve McMahon
' Date  :   21 Feb 1997
'
' A nice class wrapper around the registry functions
' Allows searching,deletion,modification and addition
' of Keys or Values.
'
' Updated 29 April 1998 for VB5.
'   * Fixed GPF in EnumerateValues
'   * Added support for all registry types, not just strings
'   * Put all declares in local class
'   * Added VB5 Enums
'   * Added CreateKey and DeleteKey methods
'
' Updated 2 January 1999
'   * The CreateExeAssociation method failed to set up the
'     association correctly if the optional document icon
'     was not provided.
'   * Added new parameters to CreateExeAssociation to set up
'     other standard handlers: Print, Add, New
'   * Provided the CreateAdditionalEXEAssociations method
'     to allow non-standard menu items to be added (for example,
'     right click on a .VBP file.  VB installs Run and Make
'     menu items).
'
' Updated 8 February 2000
'   * Ensure CreateExeAssociation and related items sets up the
'     registry keys in the
'           HKEY_LOCAL_MACHINE\SOFTWARE\Classes
'     branch as well as the HKEY_CLASSES_ROOT branch.
