SET-MOUSE-HELP (op-code 19)

When the second parameter is 1, this op-code turns the mouse pointer into a help-mode pointer--the mouse is captured and the pointer takes the shape of a question mark. When the second parameter is 0, the help-mode state is turned off--the mouse is released and the pointer returns to its default shape. This option is only supported under Microsoft Windows.

Note: If you use help automation, you don't need to use this option. Help automation automatically manages the help-mode mouse states for you. See Help Automation in User Interface Programming for more information.
