Invert Slider Control top MFC C++

Question

I have a MFC project in which I use a Slider Control. When I set this slider to vertical, the upside is the lowest and the downside is the heigest. How can I invert this, so that the highest value is closest to the top of the screen and the lowest value is closesd to the bottom of the screen?

如果您选择设置范围从0到100 - 那么您必须将滑块定位在位置100，并且每次移动滑块时，您必须取100减去滑块位置
