FAQ of the Week
Question: I was just reviewing the Paradox Table Specs in your Paradox developer reference area. I found specs through Paradox 7 only, and I'm really interested in Paradox 10. Is it available?

Answer:

No. Actually Paradox 7 "table structure" is the latest very flexible table structure. The only table structures are 1...3.x, 4.x, 5, and 7. No such thing as a Paradox 9 or 10 or 13 table structure.

Tip of the Week
Tip:

If you ever have a calculated field on a form not update when you think it should, then you can use the ObjectPAL method forceRefresh() to make the calculated field display the correct values. This can occur, for example, when you update a field involved with a calculated field using a TCursor.

Code Snippet of the Week
Calling an Oracle Stored procedure from Paradox

In Paradox, use an sqlQuery block to call store procedures. The following code uses an sqlQuery block to call an Oracle stored procedure. Use the syntax of whatever SQL server you're going against. With Oracle, if I remember correctly, you use an "execProc" or "exec" command.

sqlQuery =
SQL
;execute proc here
ENDSQL


if not dbSQL.executeSQL(sqlQuery, tcAnswer) then
errorShow()
endIf

Definition of the Week
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.

You can create either a public or 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. You can think of project aliases as aliases that belong to a certain project stored in a specific working directory.
