IT Water-Cooler for Power-Users topic:
Stamp Out Spam
by Vicki Nelson

How to fight back against spam and reclaim your inbox. As you may know, the volume of spam messages sent across the Internet has reached epidemic levels. Some industry experts estimate that three out of every five e-mail messages that are sent today are spam. The spam epidemic is costing companies, professionals, and individual users considerable amounts of time, money, and resources.

What is spam, and what can I do about it? Spam is generally defined as an unsolicited mailing, usually sent to many recipients. Most spam is commercial advertising, often for dubious products, get-rich-quick schemes, or quasi-legal services. Spam costs the sender very little to send. Most of the costs are paid by the recipient or the carriers rather than the sender. Some effective methods for preventing your e-mail address from being captured, sold or abused by spammers in the full version of this article. Click the title to read more.

Definition of the Month: Camel Casing
Camel Casing capitalizes the first character of each word except the first word, so it frequently looks like a one or two hump camel. Used by many languages including Paradox's ObjectPAL. You can contrast Camel Casing with Pascal Casing which capitalizes the first character of each word (including acronyms over two letters in length) and was popularized by Pascal.

Runtime, PDE, Package-It! Topic:
FAQ of the Month: Turn Paradox into an EXE
Question: My company has a Paradox application. Can I turn it into a true Windows application? A true Win-32 executable?

Answer:

No. To deploy your Paradox application, you can use either the full version of Paradox or the runtime version. The runtime version is almost as big as the full version but it's been free since version 9. If you deploy using the full version of Paradox, you need a license for each user. You can order a multi-user license from Corel at a deep discount.

If you really need a true Windows executable, you'll have to rewrite the application in another development tool like Delphi or Visual Studio.Net. If you need help with this you can contact a company like Prestwood Software who has experts in Paradox and in the target development tool.

Interactive Paradox: Forms Topic:
Tip of the Month
You can alter the path of objects by moving objects around in the containership hierarchy. Move objects on the same level by selecting Format | Order | Bring to Front and Format | Order | Send to Back.
