Collections are Cool!
Last updated: Wednesday, February 20, 2019
Published in: CODE Focus Magazine: 2003 - Vol. 1 - Issue 1 - Visual FoxPro 8.0, VFP Conversion Papers

Until recently, Visual FoxPro developers wanting to use collections often created their own classes that were nothing more than fancy wrappers for arrays. However, in addition to being a lot of code to write, home-built collections don't support the FOR EACH syntax, which is especially awkward when they're exposed in COM servers. Visual FoxPro 8.0 solves this problem by providing a true Collection base class.

Published in: CODE Focus Magazine: 2007 - Vol. 4 - Issue 1 - Sedna: Beyond Visual FoxPro 9, VFP Conversion Papers
New to Sedna, Visual FoxPro emulates the My namespace first introduced in Visual Basic 2005.The My namespace makes .NET Framework classes more discoverable and allows you to write less code. Sedna, the next version of Visual FoxPro (VFP), includes a My namespace as well, for the same reasons. In this article, I’ll look at how Sedna implements My.
