An application sends the SBM_GETPOS message to retrieve the current position of the scroll box of a scroll bar control. The current position is a relative value that depends on the current scrolling range. For example, if the scrolling range is 0 through 100 and the scroll box is in the middle of the bar, the current position is 50.
