Help!! How get XP-Style buttons?

I am using XTreme Controls with MFC/Visual C++ 6.  I want my dialogs to have XP-style buttons and other controls.  I noticed that the BrowseDialog sample has 2 modern XP-Style buttons 'Browse' and 'Exit', which look flatish and have an orangey sheen when your cursor moves over them, and a nice flat edit control - just what I'm after.  Problem is: I can't work out how it does it.   I assumed  at first that it was a CodeJock thing (something to do with CXTButton), but there's no sign of anything like that in the code.  I'm beginning to wonder if there's a #define or switch or something that gets Microsoft to do this automatically (comctl32.dll???).  Any help much appreciated.
