Posted by jpluimers on 2009/10/15

There are quite a few registry tricks that you can perform to influence the Delphi IDE.

If you have any registry settings to share, please let me know by posting a comment below, or filling out the contact form.

Delphi – finding the VERxxx define for a particular Delphi version: use JEDI.INC

Posted by jpluimers on 2009/10/15

Edit 20140822 since originally posting, JEDI moved to a GIT repository, so I changed some URLs and added that it is up to date until Delphi XE7.

Finding the correct VERxxx conditional define for a particular Delphi version is asked by a lot of people.

Even the first link in the above search, does not contain the full list!
But: JCL comes to the rescue

The JCL file JEDI.INC usually (read: like 99.999% of the time) is up to that with that information soon.
Currently, it contains all the defines starting with Delphi 1, up to Delphi 2010 XE7.

You can always browse the to JEDI.INC with this link to the sourceforge trunk. link to the GitHub master version.

In fact that file contains a lot more useful defines.
Actually, having the JCL and/or JVCL at hand is a very good practice: it is filled with high quality code that solves a lot of everyday problems.


VER190 (by some people attributed to the wrong Delphi version) is only used by Delphi 2007 for .NET (Delphi 2007 for Win32 used VER185 by itself and shares VER180 with Delphi 2006 for Win32).

The number 13 (in between Delphi 2009 aka Delphi 12, and Delphi 2010 aka Delphi 14) was never used as a Delphi version number
Since Delphi is mainly developed in the USA, and since a lot people there have Triskaidekaphobia, they showed mercy to those and skipped Delphi 13.

Delphi – hardcore debugging the intialization of your app, dlls and packages

Posted by jpluimers on 2009/10/15

Recently we got involved with a client having a large and complex application that (historically) consists of

  1. A main .EXE that loads
  2. Many DLLs
  3. Underlying BPLs

One of the biggest problems is debugging the startup sequence.
Somehow, when the Delphi IDE loads DLLs in the initialization sequences of units, it looses its ability symbol tables.

This article describes a few tips on how to debug those, especially where to put breakpoints.

Te Waka o Delphi · Absolute for Beginners

Posted by jpluimers on 2009/10/15

Jolyon Smith just published a great article about using the absolute keyword in Delphi.

When used with care (just like the with or goto keywords), absolute can make your code much easier to maintain.
