You can set a page size for a scroll bar. The page size represents the number of data units that can fit in the client area of the owner window given its current size. For example, if the client area can hold 16 lines of text, an application would set the page size to 16.

Whenever a window containing a scroll bar is resized, an application should call the SetScrollInfo function to set the page size.
