List of Delphi language features and version in which they were introduced/deprecated – Stack Overflow

Posted by jpluimers on 2025/08/26

Especially with the documentation for all versions of Delphi 2010 through the second-last version of Delphi have been killed from the docwiki (see The Delphi documentation site docwiki.embarcadero.com has been down/up oscillating for 4 days is now down for almost a day.), I wish that Embarcadero would put effort into maintaining the [Wayback/Archive] List of Delphi language features and version in which they were introduced/deprecated – Stack Overflow

Currently, the only alternative is the conditional defines from [Wayback/Archive] jedi/jedi.inc at master · project-jedi/jedi and (which in turn is included by for instance [Wayback/Archive] jcl/jcl.inc at master · project-jedi/jcl and [Wayback/Archive] jvcl/jvcl.inc at master · project-jedi/jvcl, but that one does not provide links to existing documentation.

Thanks to all the maintainers on Stack Overflow that have tirelessly edited this answer over and over again to keep it up to date on current and past Delphi versions, see [Wayback/Archive] Revisions to List of Delphi language features and version in which they were introduced/deprecated – Stack Overflow.

Via [Wayback/Archive] Server Overflow.

Fix a “Automatic Repair couldn’t repair your PC” on an UEFI system: when Windows cannot be located

Posted by jpluimers on 2025/08/22

I got the below error when booting a Dell Optiplex 7060 Micro, a machine not just supporting supporting UEFI but preferring it, on which I had copied a backed-up disk image, then moved the hidden Recovery partition to the end of the physical disk (to make room to extend either the OS or DATA partitions).

Fixing it lead me to a trip that was on the boundary of software archaeology, so this blog post has a truckload of archived links to information that is still relevant, but for which the original links have long vanished due to link rot or (often worse) part of the historic information got lost because of migration to new tooling forgot to cover important additions (especially in comments).

One thing that I had to unlearn was MBR disk basics, for instance the fact that on GPT disks a partition can be active (they can only be on MBR disks, but despite UEFI supporting both MBT and GPT, GPT disks are way more common and required). The same holds for partitions having a boot flag: that too only applies to MBR disks. For the same reason, bootrec is only useful for MBR disks. More details towards the end of this blog post. CSM (Compatibility Support Module) booting is the UEFI way to simulate BIOS boot for operating systems that do no support UEFI.

Back to the error at hand:

Redux: Which Windows Resource Editor do you use?

Posted by jpluimers on 2025/08/21

A long time I wrote about Which Windows Resource Editor do you use? containing a poll to choose between XN Resource Editor, IcoFX, ResEdit and Resource Hacker.

In the meantime and betweentime more than 10 years have passed and there seems to be little maintenance in (especially the non-commercial part of) Windows Resource Editor land.

From the poll back then, I also learned about a (for me) new [Wayback/Archive] Resource Editor | MelanderBlog which is still maintained every now and then. The download is at [Wayback/Archive] Downloads | MelanderBlog (at the time of writing [Wayback] ResourceEditor20190421b.zip).

More on that and download/install locations of various resource editors below a new poll.

This new poll adds Resource Editor and allows you to make multiple choices (in case you use more than one tool):

Jeroen Wiert Pluimers @wiert@mastodon.social on X: “@_ObomheseR Since JavaScript is in the group of curly based programming languages influenced by the B programming language, integer constants starting with zero are tried first in octal base. 017 octal is 15 decimal 018 octal is not possible, so becomes 18.”

Posted by jpluimers on 2025/08/20

With the constant influx of JavaScript programmers, it keeps worth repeating that you should always run JavaScript in strict mode via "use strict"; (like in the past Visual Basic 6 developers should use option strict and option explicit) to forget risky JavaScript syntax like implicit ocal constants (which were removed from the documentation in the 2009 ECMAScript 5 specification for JavaScript), and every codeline should have a test code covering it, especially for comparisons involving non-strict behaviour like the use of leading zeros.

As of the succeeding 2015 standard (ECMAScript 6), octal numbers in JavaScript start with 0o or 0O followed by a series of octal digits.

Oh, and the history of octal in computing of course has to do with 6-bit systems and also lead to 6-six bit character codes including BCD character encoding..

When Delphi cannot output the .exe file because it is locked

Posted by jpluimers on 2025/08/20

Sometimes Delphi cannot output the .exe file because it is locked. In even rarer times, Delphi itself keeps the .exe file locked (this has done it for decades and I think this is caused by a bug in the debugger).

A long time ago, I answered how to figure out where the lock comes from. A decade later a comment was added (thanks [Wayback/Archive] Server Overflow) with a command-line tool you can use for that too (but sometimes returns less results). Both are in [Wayback/Archive] compilation – Delphi does not generate any exe file – Stack Overflow Read the rest of this entry »

The spring (a twig) components – How to improve the use of Delphi Frames – Stack Overflow

Posted by jpluimers on 2025/08/19

In [Wayback/Archive] components – How to improve the use of Delphi Frames – Stack Overflow (thanks [Wayback/Archive] Brian Frost for asking!) I referred to a blog post I wrote more than 15 years ago about registering Delphi frames as components in Delphi: Delphi – Frames as visual Components – don’t forget your Sprig!

It is still a technique few use, but it is very powerful as it resolves many design time issues that arise when using Delphi frames in a normal fashion especially:

Can’t debug a .NET project in Visual Studio Code on Windows? Answered in “.net – The library hostpolicy.dll was not found – Stack Overflow”

A while ago I bumped into the error [Wayback/Archive] .net – The library hostpolicy.dll was not found – Stack Overflow (thanks [Wayback/Archive] Nate Barbettini for asking) which prevented me to debug in Visual Studio Code, but none of the answers applied to my case, so I added this one: Read the rest of this entry »
