Private Sub FillEmptyRegion(ByVal e As PaintEventArgs) ' Create a region from a rectangle. Dim originalRectangle As New Rectangle(40, 40, 40, 50) Dim smallRegion As New Region(originalRectangle) ' Call MakeEmpty. smallRegion.MakeEmpty() ' Fill the region in red and draw the original rectangle ' in black. Note there is nothing filled in. e.Graphics.FillRegion(Brushes.Red, smallRegion) e.Graphics.DrawRectangle(Pens.Black, originalRectangle) End Sub
