PictureBox and Scroll bars with Visual Basic .NET

Alright, I am working on a program in my free time. I ask a similiar question like this only applying to Visual Basic 6, but I figured out .NET is well different. Here is my question:

In Visual Basic .NET, I want to use a PictureBox, lets say its 640 by 480 pixels big, for an example, but the size should be anything. Now I want to load a picture into this this box that is bigger than it, lets say 800 by 600. Here is what I am wondering, is there a way to display an image so I can scroll or displace it so that I can see the parts that are getting cut off? Like how Internet Explorer does it when you load an image to big for your screen resolution?

Code would help so much and would be awesome!

Thank you for any help or insight.

One approach is to set the SizeMode of the PictureBox to AutoSize and then add the PictureBox to a Panel that has its AutoScroll property set to True.  ScrollBars will automatically appear if necessary.  Here is an example:

Public Class Form1
    Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "

    Public Sub New()
        MyBase.New()

        'This call is required by the Windows Form Designer.
        InitializeComponent()

        'Add any initialization after the InitializeComponent() call

    End Sub

    'Form overrides dispose to clean up the component list.
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing Then
            If Not (components Is Nothing) Then
                components.Dispose()
            End If
        End If
        MyBase.Dispose(disposing)
    End Sub

    'Required by the Windows Form Designer
    Private components As System.ComponentModel.IContainer

    'NOTE: The following procedure is required by the Windows Form Designer
    'It can be modified using the Windows Form Designer.  
    'Do not modify it using the code editor.
    Friend WithEvents Panel1 As System.Windows.Forms.Panel
    Friend WithEvents Button1 As System.Windows.Forms.Button

        Me.SuspendLayout()

        Me.Panel1.Anchor = CType((((System.Windows.Forms.AnchorStyles.Top Or System.Windows.Forms.AnchorStyles.Bottom) _

                    Or System.Windows.Forms.AnchorStyles.Right), System.Windows.Forms.AnchorStyles)
        Me.Panel1.AutoScroll = True
        Me.Panel1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle
        Me.Panel1.Location = New System.Drawing.Point(8, 8)
        Me.Panel1.Name = "Panel1"
        Me.Panel1.Size = New System.Drawing.Size(280, 216)
        Me.Panel1.TabIndex = 0

        Me.Button1.Text = "Select Image"
        '
        'Form1
        '
        Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
        Me.ClientSize = New System.Drawing.Size(296, 266)
        Me.Controls.Add(Me.Button1)
        Me.Controls.Add(Me.Panel1)
        Me.Name = "Form1"
        Me.Text = "Scrollable PictureBox Example"
        Me.ResumeLayout(False)

    End Sub

#End Region

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        OpenFileDialog1.Filter = "Image Files(*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|All files (*.*)|*.*"
        If OpenFileDialog1.ShowDialog = DialogResult.OK Then
            Try
                Panel1.Controls.Clear()
                Dim pb As New PictureBox
                pb.Location = New Point(0, 0)
                pb.SizeMode = PictureBoxSizeMode.AutoSize
                pb.Image = Image.FromFile(OpenFileDialog1.FileName)
                Panel1.Controls.Add(pb)
            Catch ex As Exception
                MessageBox.Show(ex.Message, "Error Loading Image", MessageBoxButtons.OK, MessageBoxIcon.Error)
            End Try
