4. Scroll Bar Range & Position

The scroll bar range is a pair of integers representing a minimum and maximum value associated with the scroll bar. The position is the location of the thumb within the range.

By default, the range of a scroll bar is 0 through 100, but it can be changed to a more convenient range for the program:

SetScrollRange (hwnd, iBar, iMin, iMax, bRedraw);

hwnd:	Handle to the window
iBar:	Either SB_VERT or SB_HORZ
iMin:	Minimum value to set
iMax:	Maximum value to set
bRedraw:	true, to redraw the scroll bar based on new range, or false
