Paradox ODBC Drivers topic (classic post):
Paradox, .NET, and the Wicked Back-Tick
by Wes Peterson

Using spaces within database column names may be "legal," but that doesn't mean it won't make your life harder. It's legal in Paradox tables and most database systems but you might want to avoid using spaces. Here's why - and one way to use spaces if you're using Paradox tables under .NET.

ObjectPAL Coding topic (classic post):
ObjectPAL Calendar Packaged as a Form
by Laura Lage

Some time ago I created a calendar form that I have been using instead of attaching to Microsofts calendar. This calendar works better for me than the OCX version from Microsoft did, so I thought that I would share it with you.

Installation, Setup, & BDE Topic:
Code Snippet of the Month

Paradox for Windows has two primary file types: source files and delivered files. Source files in Paradox are binary but can can be opened in later versions of Paradox and even in earlier versions if you don't use any new features: .FSL = Form, .RSL = Report, .SSL = Script, and .LSL = Library. Since Paradox source files do not compile to an EXE, Paradox developers tend to use a startup form or script to start the application.

OPAL: Language Basics Topic:
Definition of the Month: ObjectPAL
ObjectPAL stands for Object Paradox Application Language.

ObjectPAL stands for Object Paradox Application Language. The acronym portion of the name (PAL) comes from the DOS version of Paradox. The term Object was added to the name because ObjectPAL is an object-based event-driven programming environment that is much more advanced then its PAL predecessor.

FAQ of the Month: Purchasing Paradox

How can I purchase Paradox?


Answer from Corel...

Paradox was not updated from Paradox 10. It was given a new look, but the functionality remains mainly the same. Paradox 11 is available in the WordPerfect Office Professional version and can be purchased through Corel's online store or by calling us [Corel].  Paradox is also available as a standalone if you already own WordPerfect Office, and is [available] through our licensing program.  Within North America, please call 1-800-772-6735, Corel's Customer Support Services, to purchase the Paradox upgrade. We are open from Monday - Friday, 9:00 am - 7:00 pm E.S.T. and would be happy to serve you. For customers outside of North America, please visit www.corel.com/contact to locate a Corel Customer Support Services Center nearest you.

Tip of the Month

You cannot directly add code to a delivered form. For example, methodSet does not work on delivered files. However, you can use executeString() to execute ObjectPAL code even on a delivered form.
