Sample Code
I have listed the Source Code on the CD-ROM with Links below for you to browse them easily by function and be able to Cut and Paste aspects that you may need for your own applications. When you are double clicking on the source file name for the first time, you may find that you have to specify a viewer. "Wordpad" or "Notepad" are good ones to start with.
In Microsoft's Internet Explorer, you may discover that you are asked whether or not you want to save the file to disk or open it. You can open it safely.
