A while ago, I needed routines to work with absolute and relative paths on Windows.
These links were very useful:
Thanks Andreas Rejbrand and David Heffernan for the last two!

During code reviews, I often see people do things like this:
if (not DirectoryExists(Path)) then ForceDirectories(Path))
or this:
if (not TDirectory.Exists(Path)) then TDirectory.CreateDirectory((Path))
Half a year ago, I wrote about .NET/C#: do not do “if (!Directory.Exists(path)) Directory.CreateDirectory(path))”. Read the rest of this entry »

I bumped into the below answer that I gave a while (what is 4 years in a developer’s life ) on StackOverflow.
It is about Delphi Design Patterns. Sepcifically the Factory Pattern, and explains how virtual constructors implement it.
They are one of the 3 corner stones on which the component based Delphi form designer and object inspector are built:
So here it goes: Read the rest of this entry »

Just found out that the kind people at BitSavers added some scanned USCD Pascal documentation in PDF format:
It reminds me of my early Pascal days on Apple ][. UCSD Pascal was so slow that I was glad to discover Turbo Pascal 1.0, which lacked some of the UCSD Pascal features (for instance cross platform – including Mac, almost 30 years ago! – and Turtle graphics), but was blazingly fast.
Trade offs indeed (:

Sometimes a generic answer to a specific answer gives people a lot more insight into what they actually want to accomplish than a specific answer.
Plus that the knowledge does not only apply to VCL in any Delphi version: it works in any development environment where you can draw.
That’s why I like this 2D transformation answer so much: Read the rest of this entry »

On the blog from Embarcadero MVP Luis Felipe González Torres are some great Delphi XE4 iOS demos.
However, the blog is Spanish (that’s probably why he is not on DelphiFeeds), so if you do not understand that you had to live with the Google Translate versions of the pages.
Until CodeRage Mobile that is: Anders Ohlsson gave a English presentation:
Creating Apple Push Notification Services (APNS) for your Mobile Applications
iOS supports the Apple Push Notification Services (APNS) This session will show you how to create a push notification services as part of your mobile application. APNS is service for sending information to iOS and OSX devices. This session will show you how to create server and device applications that create notifications containing the device token and JSON payload property list.
Basically he covered these Spanish blog posts where you can download the source code (Google translation in parenthesis):

Cool to know that DIPP is able to strip directives from Delphi source code:
The freeware program DIPP from Delphi Inspiration can remove conditionals.
Even though DIPP does not support post-Delphi-2007 language enhancements, it usually does a very good job.
