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
