While scheduling this year’s projects, it was clear that it would become impossible to have the summer holiday in the summer (last year was also outside, as we fulfilled Nicolette’s dream: visit the Antarctic region).
So we moved this year’s holiday to early November, hoping that would be outside the Fall conference season.
Alas, EKON (Entwickler-Konferenz.de), this year in Düsseldorf, Germany, moved themselves to November, so this will be the first EKON ever that I won’t attend (out of 3 or 4 people that never missed one). Sorry guys I will miss the great speakers, sessions and workshops (:
I am going to speak on two other European Delphi conferences though:
I’m really looking forward meeting the attendees, speakers and organizations there. Conferences are always a lot of fun and a great way for me of learning new things.

Two days ago I ran into the bug below while porting some code from Delphi 2006 to Delphi XE2, posted on StackOverflow, and got solutions in very little time.
Thanks Andreas Hausladen, David Heffernan, Ken White, Sertac Akyuz, Rudy Velthuis, for answering, providing solutions and verifying!
Note that this worked up until Delphi XE, and has been fixed in Delphi XE3 (which for this project I can’t use as the client upgraded to XE2 without SA).
Problem
- I get the error mentioned further on error when debugging an executable in Delphi XE2 update 4 under these circumstances:
- that depends on mqic.dll from WebShpere that is in C:\Program Files \IBM\WebSphere MQ\bin\mqic.dll and C:\Program Files\IBM\WebSphere MQ\bin is on the system path (not on the user path).
- is being debugged with an override environment variable in the Run -> Parameters -> Debugger -> Environment Block -> User overrides
- Including System Variables on the same property page is checked
This is the error (it’s a Windows DLL load error marked “System Error”).
The program can’t start because mqic.dll is missing from your computer. Try reinstalling the program to fix this problem.

Today I found out the hard way that you really need a build integration system for managing VersionInfo in Delphi applications: as of Delphi XE2 it is broken in the IDE.
See these links:
This is the only workable workaround so far:

Last week, ModelMaker Code Explorer 10.0.0 got released:
General new features
- Delphi XE3 / RAD Studio XE3 support
(as well as support from Delphi 5 and up)
- Member Search list allows filtering on member type. Todo items are also displayed.
- Pascal, new option on tab MMX | Properties | Pascal | New Entities | Methods: Empty Parameter lists. This controls how empty method, procedure and delegate parameter lists are emitted: either suppressed – pascal style, or emitted as ( ) – c-style.
- Locate Type: displays a filtered list of previously parsed class and interface types. This is used to open the containing source file and locate a class inside the file. Default key binding Alt+Shift+T.
Solved bugs
- Text containing line breaks and stored in XML (settings, snippets) could contain stray 0x0B (#11) characters. Solved.
- An access violation at shutdown could occur in older Delphi IDEs if MMX was not docked. Solved.
- If the Delphi IDE editor buffer contains a stray #0 (which is bad in itself) would cause all kinds of exception in MMX. MMX now detects stray #0’s and abort all editing operations, displaying the line:column of the bad #0 character.
- Pascal: relative paths starting with \ (relative to root in drive) would not be handled correct. Solved

A few weeks ago, Bill Karwin did a must watch webinar on the prevention SQL Injection titled “SQL Injection Myths and Fallacies“.
Bill Karwin (twitter, new blog, old blog, Amazon) is famous for much work in the SQL database community, including InterBase/Firebird, mySQL, Oracle and many more.
He also:
Anyway, his webinar is awesome. Be sure to get the slides, watch the replay, and read the questions follow up.
Watching it you’ll get a better understanding of defending against SQL injection.
A few very valuable points he made: Read the rest of this entry »

Last week I posted an in depth answer on StackOverflow.com about the memory allocation difference in Delphi and Fortran, or more accurately in two different kinds of languages.
You have:
- column major order (not only used in Fortran and other science centric languages, but also in the shading languages GLSL and HLSL that can be used in FireMonkey)
- row major order (used in most other languages, for instance Delphi, C, etc)
A very important aspect is the order of for optimized loops. For column major order, the optimum is inside out (as the inner arrays/records are in consecutive memory locations), but for row major order, it is the exact inverse.
One of the consequences is that in Fortran it is a very fast operation to pass an array of inner fields as parameter to a method.
This is what I wrote: Read the rest of this entry »

Now that the there are RadStudio XE3 demos available at SourceForge.net Repository – [radstudiodemos] Index of /branches/RadStudio_XE3, and a post on a Delphi Event in New Zeeland rumours of an eminent Delphi/RAD Studio XE3 version start to raise.
It is fun to watch the activity stats on the SourceForge project RAD Studio Demo Code and correlate them to the Delphi release and update dates.
I made PNG images of two graphs. Click on them to enlarge, or click on the links to get to the statistics pages.
Note that when the span is wide enough, activity gets summed to the start of the month (first picture).

There was a nice short discussion on Entropy Overload where Ivan Levanshew seemed to want to be Delphi way more C++ and Barry Kelly explains why Delphi isn’t C++.
Both Delphi and C++ are great languages, but both have weaknesses too. It is good that their individual strengths complement each other, and their weaknesses don’t crossover too much.
Ivan Levashew said…
It’s XE2 now, and there is still no proper RAII despite Delphi runtime already having all the required functionality for years. Variants copying and destruction is an example.
It’s a pity. Read the rest of this entry »

Just a few notes on things I told Delphi cross development students over the last nine months or so.
For Mac OS X apps:
- The Platform Assistant Server that ships with Delphi XE2
For iOS apps:
Steps:
- Become a registered Apple Developer
- Download and install xCode 4 when you run on OS X 10.7 Lion or higher, or
Download and install xCode 3 when you run on OS X 10.6 Leopard
- Download and install FreePascal 2.4.4
xCode includes the iOS SDK
