Color Selector

Hi
Does anybody know how to create a color spectrum or a "fill" like the one in PaintShop Pro
using VB?

Thank you

Yes, but it's slow (Nothing for realtme-graphix)
But, let's say in a paint app
You will have to set the start point for the filling and the go in all directions from that point and check wether the color is within the limits or not. I can explain it with some code if you want
