The size of the scroll box is controlled by the range and page size of the scroll bar. You can use the CScrollBar::SetScrollInfo function to control these settings, specifically the nMin, nMax, and nPage members of the SCROLLINFO structure.

You can find more information on scroll bars on this page in MSDN - read the "Scroll Box Position and Scrolling Range" section.
