Thanks Samaliani for posting a Delphi GetWinControlName function as answer to Is there a way to get a VCL Control’s name through the windows API?
The cool thing: it works across processes (as long as your own process has ReadProcessMemory rights).
It works from Delphi XE3 and up.
Be sure to also read the comments by Danny Thorpe on the automation framework in Delphi: that might also be a good place to get this information from.

Apart from the mandatory Joel on Software article about Unicode and Character sets, these two articles are of great value too:
Fun to read from that blog is the Historical Technology section including this article:

I learned something new today (thanks Vin Colgin) the Delphi Design-Time Component Name is Limited to 63 characters.
Uwe Raabe found out that this an Object Inspector thing due to this constant in DesignIntf.pas:
const
MaxIdentLength = 63;
It has been probably there since Delphi 1 and has been documented on-line since at least Delphi 2007.
I remember having had long (like 100+ character) identifiers in source code, but not in the Object Inspector.
Now I know you can’t (:

There is an interesting G+ discussion thread about generic Dictionaries in Delphi.
It covers the stock TObjectDictionary in the Generic.Collections unit, Spring4D, performance characteristics like O(1), O(log n), etc, and implementation details like fill factors and hashing algorithms.
Worth reading at Steve Maughan – Google+ – TObjectDictionary Advice Needed I’ve been using Delphi for….
Since TObjectDictionary hasn’t changed much since the introduction of generics in Delphi, this discussion is valid for at least Delphi XE and up (and probably Delphi 2010 and 2009 as well).
I’m not sure about these last ones as like Andreas Hausladen, I’m cutting back on the Delphi versions I regularly use, which for now are mainly XE6, XE3, XE and 2007).

IP geolocation is hard, and very dependent on where you are in the world. Providers giving different or confusing results are not exceptional.
See the struggle at Dan Sohad – Google+ – Hi! I working in a IP locate app. I’m using as “motors”: … where Dan Sohad tries a Delphi implementation.

Years after Allen Bauer and a few others wrote about Delphi MultiCast events, the Spring4D framework now supports MultiCast events on 3 platforms:
Depending on the platform, the minimum required Delphi version is this (the develop branch builds in Delphi XE6):
- Win32: Delphi 2010 and up.
- Win64: Delphi XE2 and up.
- MacOSX: Delphi XE2 and up.
There are plans for support on Mobile platforms, and Spring4D needs help with that:
- The Intel implementation is written in Assembly, and fast.
- The Arm compiler does not allow Assembly language for various reasons.
So there is a need for an ARM solution not based on assembly in the Delphi code, preferably as cross-platform as possible. Read the rest of this entry »

After finding out that Raize Components 6 and Raize Components 5 updates for Delphi XE6 I checked Raize Software‘s latest news page and was glad to see that these also got updates:
The only one not yet having XE6 support is this one:

Just found out that a new version of Raize Components 6 with Delphi XE6 support got released.
Raize Components 6 actually supports Delphi 2009 through XE6 (and C++ Builder and RAD Studio).
Older Delphi versions are also supported by older Raize Component versions, as Ray Konopka posted last year:
via Raize Software Support Forums • View topic – Installing multiple versions of the Raize Components.
(In the above quote, I included the links to the various trial versions).
There is also the famous Demo program download RCDemo.zip and nice videos:
via Raize Components Demo/Trial Edition.
For the dot version nitpickers, here are the current versions as of writing: Read the rest of this entry »

Interesting: Roman Yankovsky just wrote about a property syntax that I didn’t know about either:
Today I learned… :)
I didn’t know about this syntax for properties:
FStrings: array [0..1] of string;
property String0: string read FStrings[0] write FStrings[0];
property String1: string read FStrings[1] write FStrings[1];
Now I hope someone finds out in which Delphi version this syntax was introduced.
