// Class that wraps CUxThemeFile. CUxThemeFile automatically closes the section
|
|
// member variable handle. This makes usage of the class difficult because
|
|
// it doesn't duplicate the handle but it takes ownership. It does declare
|
|
// the handle as a PUBLIC member variable so we capitalize on this poor
|
|
// design. This class wraps CUxThemeFile to make the life of users of this
|
|
// class easier by not having them worry about closing the handles or not.
|
|
// When you use this class the handle is NOT closed.
