Reversible Frames on Windows Forms

[occcy]

Hello! I want to draw a reversible frame on my windows form. I have found the method ControlPaint.DrawReversibleFrame, but this method is not, what I'm looking for. I need a dotted frame like a fokus rectangle. Is there somebody who can tell me, how I can draw such a frame or how I can draw dashed lines with a XOR combination of colors? :confused: Thanks Björn

If you need a focus rectangle, why not use ControlPaint.DrawFocusRectangle? You can specify both the foreground and background colors. If you need to invert the colors, you can create a new Color by XOR'ing each of the R, G, and B components with 0 or 0xfff. If you want to draw a rectangle around the bounds of the control itself use the Control.Bounds property for the rectangle param of the DrawFocusRectangle method. If neither of these approaches is quite what you want, you can draw dotted lines by using a custom Pen with the Pen.DashStyle property set in calls to Graphics.DrawLine or Graphics.DrawRectangle and similar methods.
