//  Class CRegistryValueName
//
//  When initialized, this class takes as input the Name and KeyName
//  fields of a property table item. It then initializes its member
//  variables m_pszName and m_pszKeyName as follows.
//
//  m_pszName contains all the characters of Name after the last backslash
//  character.
//  To m_pszKeyName is appended all the characters of Name upto (but not
//  including) the last backslash character.
//
//  For example: If Name is "Groups\AdminExtensions" and KeyName is NULL,
//  m_pszKeyName will be "Groups" and m_pszName will be "AdminExtensions"
//
//  The allocated memory is automatically freed during the destruction of
//  the CRegistryValueName object.
