netAboutBox

Overview

The AboutBox is the window that shows information about the author of a program. Usually it is the company logo, address, company hyperlink and the version of the software. Depending on the complexity of the program additional information about the user's machine, operating system, .NET and the APL interpreter may be added for troubleshooting help. This Wiki is about providing snippets of code useful in building such an AboutBox when using Dyalog APL.
