Use SMB_SETRANGE message.

You can also use the SMB_SETSCROLLINFO and SMB_GETSCROLLINFO messages.  These allow you te get/set more options than just the ends of the range.  

Note these messages (including SMB_SETRANGE) only work with scrollbar controls, they won't work with the vertical and horizontal "standard scrollbars" associated with a window.  (Just with scrollbar controls inside a window).

If you want to work with a window's "standard scrollbar", you can use the SetScrollInfo() and GetScrollInfo() functions.

By the way.  Doing this to another application's window could have undesirable effects.  Some programs may assume that these values are certain ranges and may crash or produce weird behaviors when you change them without their "knowing" about it.
