Scrolling Text with the WM_SIZE Message
When processing the
WM_SIZE message, it is convenient to adjust the scrolling range and scrolling
position to reflect the dimensions of the client area as well as the number of lines
of text that will be displayed.
The
SetScrollInfo function sets the minimum and maximum position values, the page size, and the
scrolling position for a scroll bar. For versions earlier than 4.0, use the
SetScrollRange function to set the minimum and maximum position values, and the
SetScrollPos function to adjust the scroll box to reflect the scrolling position.
