The following code example demonstrates how to load a bitmap from an Icon handle, using the GraphicsUnit enumeration, and the use of the Round method to draw the rectangle bounds of a bitmap.
This example is designed to be used with Windows Forms. Create a form that contains a button named Button2. Paste the code into the form and associate this method with the button's Click event.
Private Sub Button2_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button2.Click Dim bitmap1 As Bitmap = Bitmap.FromHicon(SystemIcons.Hand.Handle) Dim formGraphics As Graphics = Me.CreateGraphics() Dim units As GraphicsUnit = GraphicsUnit.Point Dim bmpRectangleF As RectangleF = bitmap1.GetBounds(units) Dim bmpRectangle As Rectangle = Rectangle.Round(bmpRectangleF) formGraphics.DrawRectangle(Pens.Blue, bmpRectangle) formGraphics.Dispose() End Sub
