Class constructors and Generics
Yet Another Programming Blog
– The new great addition to the Delphi language in Delphi 2010 is the possibility to specify a class constructor and a class destructor to your class/record.

DeHL 0.6 available
Yet Another Programming Blog
– Yes I know I have skipped 0.5. The reality is that 0.5 was due a long time ago, but I did not have enough free time on my hands to complete the unit testing for all new features added. I always try to add as many unit tests as possible to test all possible scenarios. This release features a general ...

Extending TObject with data at runtime
Yet Another Programming Blog
– In a recent comment on this blog someone suggested a way of extending an existing object instance with custom data at run-time. The main idea is to be able to “assign” to an arbitrary object (whose sources you cannot change) some other object at run-time. This may prove to be useful in ...

Arbitrary precision integers
Yet Another Programming Blog
– I have decided to extract the BigInteger and BigCardinal data types from DeHL and make a bundle with them separately. Someone may be interested in these types and not so much in DeHL. The attached unit should compile on D2007 and D2006 (not sure for earlier versions). What can you learn: Shows you ...

Playing with Windows 7
Yet Another Programming Blog
– I was playing around with some (default Windows) programs these days and noticed that taskbar items for those programs show some cool effects whenever there is some progress going on So I decided to write a little unit to take advantage of these effects in one of my Delphi applications. To take ...

DeHL documentation
Yet Another Programming Blog
– Since I had a few requests, I have started putting together some documentation on DeHL. It’s pretty basic and only includes some conceptual stuff, not API documentation. You can find it here. Version 0.5 is shaping up quite well with tons of changes, and new stuff coming in — but ...

DeHL 0.4: Linq-ifying Delphi
Yet Another Programming Blog
– Since I have started working on DeHL, one of the main purposes was to get to the point where I could use Linq-like extensions on collection classes. Of course I could not call the new functionality Linq since it’s not language-integrated, so I decided to give it another name: Enex (aka ...

More about enumerables
Yet Another Programming Blog
– In the last post I have described how enumeration works in Delphi. Now I will try to expand the subject a bit and make a more general description of what enumerability actually means and how it can solve some basic problems and patterns. “An enumrebale is not necessarily a collection“. ...

Enumerables in Delphi
Yet Another Programming Blog
– It is not a surprise that most programming languages in our time have the built-in support for enumerators/iterators. This is a mandatory feature since enumerators and enumerable collections simplify the development of applications and make the code cleaner. Languages such as C#, Java or Delphi have ...
