how to put a scalable image into a form (or panel)

[Wolfgang]

I'm a Java developer relatively new to to VB .NET (and I don't know
the old VB6 at all). I know how to draw lines, circles and other
simple shapes on a form in VB.NET (using the onPaint event).

Could someone out there please give me a simple example, or point me
to a SIMPLE example that:

1) puts a given JPEG (or GIF, or TIF) image into a form or panel (or
whatever other control is appropriate)

2) allows me to re-size the form or panel in the usual manner by
grabbing a corner with the mouse pointer and dragging it.
As I resize the form, the image is to re-scale itself, as appropriate,
to keep the form/panel filled completely.

Thanks for any help and advice,

For example:

\\\
Imports System
Imports System.ComponentModel
Imports System.Drawing
Imports System.Windows.Forms

Public Class UserControl1
Inherits Panel

Public Sub New()
Me.SetStyle(ControlStyles.ResizeRedraw, True)
Me.UpdateStyles()
End Sub

Protected Overrides Sub OnPaintBackground( _
ByVal e As PaintEventArgs _
)
If Not Me.BackgroundImage Is Nothing Then
e.Graphics.DrawImage( _
Me.BackgroundImage, 0, 0, Me.Width, Me.Height _
)
End If
End Sub
End Class
