10. ACKNOWLEDGEMENTS

• The code for Shaded Buttons (at least when I started it) was largely based on code found in OS/2 Presentation Manager Programming (Charles Petzold). A lot of other code is also taken from there (part of Test1 and Test2 for example).
• I used the documentation from Prominare's site to figure out how the normal buttons behave, and how to get PMCX to work.
• I used some information from one of IBM's web sites, to figure out how normal buttons behave, what certain messages mean, and what functions to use.
• Thanks to Mark Benge and Matt Smith, for their GUI Corner column that used to appear in OS/2 Magazine, before it shut down. Their series on custom controls was especially usefull.
• Thanks to IBM for creating such a great operating system.
