Fill it with new color.

but that's the thing...
how??
i have no idea how to do it...:blush: :confused:

thanks...

How you draw a rectangle? do you know that? The same way you can file a rectangle. For example in a paint event:

VB Code:

Dim br As New SolidBrush(Color.FromArgb(a, r, g, b))
e.Graphics.FillRectangle(br, New RectangleF(0, 0, 100, 100))

Thanks for your help

i really appreciate...it.

take caer...

see ya:wave:
