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.

Code Snippet of the Month

The following code snippet adds an appointment to your Outlook calendar. Tested with Paradox 9 and Outlook 2003 but should work with later versions of both programs.

Note, you will get a Error opening server 'Outlook.Application' error if your antivirus program is blocking Outlook access.

var

 oleOutlook oleAuto
 oleAppointment oleAuto
endVar
  
;The open will fail if your AntiVirus program is blocking access.

oleOutlook.open("Outlook.Application")
oleAppointment=oleOutlook.CreateItem(1)
  
oleAppointment.Subject = "Test From ObjectPAL"

oleAppointment.Body="You can add appointments from ObjectPAL."
oleAppointment.Start=dateTime() ;Adds an appointment now.
oleAppointment.Duration=60

oleAppointment.ReminderSet=True
oleAppointment.Location="My Office"
oleAppointment.BusyStatus = 2
  
oleAppointment.save()

Definition of the Month: Data Model
A data model is a diagram of the tables used in a form or report. It identifies the tables, defines the relationships between them (links), and has features including the ability to filter each table and mark any table as read-only. You can save a data model (.dm) and reuse it with another form or report.

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.

Tip of the Month

If you need to rename many objects one right after the other, use the Object Tree. By selecting and inspecting each object on the Object Tree, you can quickly rename many objects.
