How do I change the alpha channel of a color in a color picker dialog?
Question
I've made a Color Picker in C#, but someone asked me to make an Alpha property. So far it works great, except for the part of the Alpha property itself.
The question is: How do I change the ColorDialog.Color.A by scrolling up and down a ScrollBar?
