You really want to use the date-time picker control, and not a scrollbar because:
1) What's the minimum date to be represented by your scroll bar? (0/0/0000 would be a lot of dates to scroll through!)
2) What's the maximum date to be represented by your scroll bar? (too soon, and you've re-created the Y2K bug)
3) Scrollbars are typically limited to 32767 values, or 89 years worth (not a lot of days, in other words)
4) With 32k worth of dates in there, it becomes physically hard to select one, as your mouse usually doesn't have the resolution needed. Even using the keyboard accelerators makes it tough.
