18 years ago, Delphi 1 was launched (still not sure if valentine’s day was a good idea for a product launch).
I wonder – when writing this long before valentine’s day – if the matureness of Delphi finally introduced real undo/redo in the form designer.
Probably still a dream, but still…

A couple of notes on NMQ_MQ_LIB and the WebSphere MQ aka MQSeries client libraries:
And a few links:
I needed this to get some apps talking to MQ on AS/400 aka iSeries aka System i working correctly by getting the DLLs right.

This is way cool, and has been there for a long time, and I completely missed it until recently (:
On the Stack Exchange Data Explorer, you can write your own queries for any of the StackExchange sites as they share a common database infrastructure.
The queries can even contain an execution plan, and given the large number of questions (the total of Questions (table Posts) is total over 10 million now: select count(*) as QuestionCount from Posts as Questions).
There are many examples, for instance this one by sam.saffron and TLama that lists posts outside the Delphi area: Read the rest of this entry »

One of the really nice contributions on StackOverflow by Allen Bauer is almost 3 years ago.
It is about these three Delphi VCL methods introduced by TWinControl to make control development easier:
The really cool thing is that this API has been stable since 1995, and still allows you to subclass windows controls or create your own controls in a very simple way.
Note that Allen does not cover DestroyWnd or DestroyWindowHandle, but those are just counterparts of CreateWnd and CreateWindowHandle.
In normal Delphi application code, you have less Destroy overrides than Create overrides, and the same holds for control development.

Thanks Warren Postma for this Google Plus mention: both the question and answer are incredibly insightful.
And indeed: the code from the answer is not possible in with Generics Delphi (:

Just in case you wonder about Property using Generics in Delphi, they are not possible.
Thanks David for mentioning it, Hallvard for mentioning it even earlier and Rudy for confirming it.
These are supported with Generics in Delphi:
All of the supported aspects are linked to articles from excellent authors. There is far more on the internet about Delphi and Generics, but those are a good start.
Thanks Malcolm, Phil, Barry, Hallvard, Jolyon and many others for posting all those articles!
Note that this is not possible in C# either, Julian Bucknall organized a chat and explains why, but there is a workaround which I might try to port to Delphi in the future.

If Gloegg@Bonn has posted a few nice Delphi entries over the last couple of years, so he should be added to DelphiFeeds.
His last one was a very funny post on the Delphi implementation of Sleep sort.
It uses Generics, so you need at least Delphi 2009 or better.

Back in the days I started programming, Micro Cornucopia was a wonderful magazine, so I’m glad that BitSavers scanned a few more issues and put them online today, a week after some great PDF scans: Turbo Assembler/Debugger (1993/1994), Borland C++/Object Windows Library (1993):
They covered a lot of languages (x86 and 68k assembly, C, C++, Turbo Pascal and many more), and very interesting hardware designs.

The PDF Archive at bitsavers.org has recently put online these raster image PDF scans from Turbo Assembler/Debugger (1993/1994) and Borland C++/Object Windows Library (1993)
Remnants of the past, usefull for RAD Studio, Delphi and C++ Builder developers wanting to know a bit of history (: Read the rest of this entry »
