Hide the default buttons which are

FALSE:
Shows the default buttons (OK/Apply/Cancel/Help).
(Default)
Remarks
When you set this parameter to 'TRUE', the behavior of the prior version of 'CTreePropertySheet'
is imitated. Otherwise (preferable) the standard buttons of the 'CPropertySheet'
are used, so the compatibility with future windows versions and the localization
issues are handled better.
