 MUSTEST: Custom Control Sample for Implementing a Spin Box

 MUSTEST is an extension to the Microsoft(R) Windows(TM) 
 interface. MUSTEST calls the dynamic link library (DLL) 
 MUSCROLL.DLL that contains interface functions for the 
 Windows Software Development Kit (SDK) Dialog Editor.

 MUSCROLL.DLL implements a miniature scrollbar that consists 
 of only scroll arrows. Because MUSCROLL is much smaller 
 than a standard scrollbar, it can be placed in an edit 
 control to create a spin box (for examples, see Control 
 Panel's Date/Time dialog box). When you click a scroll 
 arrow, MUSCROLL sends scroll messages to its associate 
 window. Initially, the associate window is the parent of 
 the control and can do whatever it desires with the 
 messages. MUSCROLL also provides a cut-and-paste spin box 
 implementation.

 For a complete list of the programming interface, messages, 
 and functions, see the MUSCROLL.TXT file.

 MUSTEST was built and tested under Microsoft Windows 
 version 3.1.
