  10 //\r
  11 // Heavily based on the CVisualStyleXP class of David Yuheng Zhao. The difference\r
  12 // is that the dll is global and the HTHEME handle is wrapped. The HTHEME handle is\r
  13 // automatically released as the object is deleted. All API functions not directly\r
  14 // related to a HTHEME instance are realized as static methods. To optimize the\r
  15 // execution speed, static function pointers are used. During execution, either\r
  16 // the actual function or the failure function is assigned to the static function\r
  17 // pointer, which is used from there on.\r
  18 //\r
  19 // To explicitly Release the dll, call the static Release method. To check whether\r
  20 // Theming is available, that is, if the platform is XP or newer, use the static\r
  21 // method IsAvailable\r

  25 //\r
  26 //\r
  27 // How to use:\r

  29 //    HTHEME hTheme = OpenThemeData(...);\r
