示例1: SetScrollBarValues
public void 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
