Заметки

You must provide the values required by the SCROLLINFO structure parameters, including the flag values.

The SCROLLINFO structure contains information about a scroll bar, including the minimum and maximum scrolling positions, the page size, and the position of the scroll box (the thumb). See the SCROLLINFO structure topic in the Windows SDK for more information about changing the structure defaults.
