Variant Records are a feature that has been in the Pascal language since Standard Pascal.
A cool page for historic perspective is R3R: Pascal Features in Popular Compilers, hopefully someone will update it to more modern versions of the mentioned compilers.
There is not much official documentation on the Delphi side on this, so below some parts of a case I used for a project that started in 1997 and is still in use to day. Read the rest of this entry »

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 »

Though the sample question is in C#, it applies to almost any language and framework: for relatively simple checks like IsHex(), you can go the RegEx way, or the compound if-statement way.
Which kind of function do you like most?
I’m not only interested in the percentages, so let me know in the comments why.

PS: if you want to use RegEx in .NET, you can compile them to IL, but be very cautious for the compilation overhead.

I’ve been working on a project that uses both COBOL and Delphi.
For documentation purposes, Syntax Highlighted code makes your code so much easier to read.
Delphi has GExperts for source code export (in either HTML or RTF), but it took me a while to find a good syntax highlighter for COBOL.
I finally found a COBOL syntax highighter at tohtml.com: it exports to HTML.
I’m glad I found that site, as they have a ton of syntax highlighters, divided into groups.
Quite amusing to see COBOL classified as ‘rare’ (given that it has one of the largest code bases in the world).
This is what they support:
