A problem with a GDI+.

[AlexMesquita]

I am using this code to paint my form with a gradient color, but when I open any window ( a messagebox, for example ), or a menu, over my Panel ( MyPanel), and close it, it draws a hole in my grandient color. Why?

Dim MyobjBrush As New Drawing2D.LinearGradientBrush _
     (MyPanel.DisplayRectangle, Color.AliceBlue,Color.MediumSlateBlue, _
                    Drawing2D.LinearGradientMode.Horizontal)
Dim MyobjGraphics As Graphics = MyPanel.CreateGraphics()

objGraphics.FillRectangle(MyobjBrush, MyPanel.DisplayRectangle)
MyobjBrush.Dispose()
MyobjGraphics.Dispose()

The problem was solved.
Instead of using MyPanel.CreateGraphics(), I should be using e.Graphics.
