示例1: SetScrollBarValues

Public Sub SetScrollBarValues()

    'Set the following scrollbar properties:

    'Minimum: Set to 0

    'SmallChange and LargeChange: Per UI guidelines, these must be set
    '    relative to the size of the view that the user sees, not to
    '    the total size including the unseen part.  In this example,
    '    these must be set relative to the picture box, not to the image.

    'Maximum: Calculate in steps:
    'Step 1: The maximum to scroll is the size of the unseen part.
    'Step 2: Add the size of visible scrollbars if necessary.
    'Step 3: Add an adjustment factor of ScrollBar.LargeChange.


    'Configure the horizontal scrollbar
    '---------------------------------------------
    If (Me.hScrollBar1.Visible) Then

        Me.hScrollBar1.Minimum = 0
        Me.hScrollBar1.SmallChange = CInt(Me.pictureBox1.Width / 20)
        Me.hScrollBar1.LargeChange = CInt(Me.pictureBox1.Width / 10)

        Me.hScrollBar1.Maximum = Me.pictureBox1.Image.Size.Width - pictureBox1.ClientSize.Width  'step 1

        If (Me.vScrollBar1.Visible) Then 'step 2

            Me.hScrollBar1.Maximum += Me.vScrollBar1.Width
        End If

        Me.hScrollBar1.Maximum += Me.hScrollBar1.LargeChange 'step 3
    End If

    'Configure the vertical scrollbar

        Me.vScrollBar1.LargeChange = CInt(Me.pictureBox1.Height / 10)

        Me.vScrollBar1.Maximum = Me.pictureBox1.Image.Size.Height - pictureBox1.ClientSize.Height 'step 1
