Setup Exchange E-Mail Queue
by Jon Speare

About: An email queue is setup for 2+ workers as a queue where those working the queue move emails to subfolders or delete as they proceed. Subfolders sample: Assigned, Completed, Ignored, etc. Good for groups of staff to work. Our support@prestwood.com is an email queue. Our scheduler and tech staff in our Network Operating Center (NOC) work this queue.

Paradox Tables topic (classic post):
BDE Best Practices: Safely Use Paradox Tables
by Mike Prestwood

Use a file server (not a workstation) to store your data, disable Oplocks on the filer server, and configure the BDE (local share to true and optimize if desired). Finally, if workstations are crashing, fix em so they don't. You want clean running computers that don't crash.

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.

OPAL: Wicked Coding Tasks Topic:
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.


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

oleAppointment.Subject = "Test From ObjectPAL"

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

oleAppointment.Location="My Office"
oleAppointment.BusyStatus = 2
Interactive Paradox: Using Data Topic:
Definition of the Month: Project Alias
A project alias, like public aliases, point to a folder. Project aliases are stored in the PDOXWORK.CFG file, which is loaded whenever you change working directories.
Paradox & ObjectPAL Topic:
Resource Link of the Month: RDA World Wide
Many downloadable ObjectPal examples as well as additional development tools.
Installation, Setup, & BDE Topic:

I recently upgraded to Windows XP and now Paradox 11 cannot open SQL Server database tables. In the open-dialog-box, I see the aliases, but cannot select one which is linked to a SQL server database. The same thing happens, trying to create a QBE query, new form, etc... All existing queries, forms, ... are working (using these aliases).


Solution was to apply the latest BDE patch, all works as it should.

OPAL: Language Details Topic:
Tip of the Month

Two advantages of using constants are that they humanize your code and help make managing your code easier. They humanize your code by making your code easier to read. A constant named tax is easier to remember and understand than 8.125. Constants help you maintain your code by centralizing values. If the tax rate in your area changes from 8.125 to 8.5, you change the constant in one location.
