If ever in need to translate C/C++ headers or code to Delphi, this refernece by Rudy Velthuis – a dentist with a strong interest in programming – is the best I could find: Rudy’s Delphi Corner – Pitfalls of converting.
It is written in a pretty version agnostic way, and covers the vast majority of conversion topics.
And it has been updated over time numerous times.

I need to give this link from Jonathan Lange which was shared by David Millington some thought:
There they add fuzzers to help testing an ADT: in this case an Abstract Data Type in the form of a red-black tree.
And then see if it can be added to DUnit and NUnit or MSTest/VSTest in some way.
In the original post by Jonathan Lange, an important remark was made by Eric Castelijn:
… the downside being that having non deterministic tests means having test failures that are hard to repeat
…
When fuzzing multiple or composite values, the chances that you will hit interesting edge cases semi-reliably will drop dramatically, in my experience

The Default IDE Shortcut Keys – Delphi Programming was a good starting point to find out how to disable column or line blocks.
Since the table there is incomplete (even the Embarcadero documentation is wrong as some shortcuts can turn on and off a mode), here are the relevant shortcuts keys:
| Ctrl + O + C | Turns on/off |
Delphi 5 and up |
| Ctrl + O + K | Turns on/off block selection mode | Delphi 5 and up |
| Ctrl + O + L | Selects current line (and turns off block selection mode) | Delphi 5 and up |
This is especially useful when the block selection is stuck (this happens every now and then: it’s a known bug).

Great post by Marjan Venema when you need to migrate your old Delphi programs to the modern Delphi world: [Wayback] 20 resources on migrating to Unicode with Delphi | Software on a String.
I’m glad that some of the links overlap with what I posted and presented in the past at:

I’ve been doing Aspect Oriented Programming (AOP) in .NET for a long while, mostly using PostSharp LAOS as that was the first AOP .NET library I encountered (5 years ago it became PostSharp 2.0, now it is already at its 10th anniversary!).
AOP allows you to perform separate of concerns (SoC) in your application, especially in the area of cross-cutting concerns like for instance logging, authorization, monitoring, etc.
It took a while in Delphi to allow for AOP, but the TVirtualMethodInterceptor (that introduced in Delphi 2010) can be used to do AOP (only for Virtual Methods, which is still way better than having no AOP at all).
The code requires a lot of manual labor. so I was glad that DSharp (a great library by Stefan Glienke – one of the leading Spring4D contributors) contains a nice wrapper around TVirtualMethodInterceptor so you can use AOP in an attribute based fashion.
Nick Hodges recorded a good introductory video on AOP in Delphi with slides and demo code:
Note that besides DSharp, also MeAOP and Infra provided support for AOP in Delphi, but these haven’t had updates since 2010.

A while ago, I posted [WayBack] the below StackOverflow answer. Recently a friend asked me about command-line parsing in Delphi, so here is the re-run:
Delphi contains a really nice unit called CommandParser with a [WayBack] TCommandParser class that does commandline parsing for you. Since it has [WayBack] virtually no documentation, here are a few things to get started. It works even in Delphi 2007.
I have a HiddenExecutable example at our open source bo repository.
Basically you:
THiddenExecuteSettings in the HiddenExecuteSettingsUnitTHiddenExecuteArguments in theTHiddenExecuteArgumentsUnit (in retrospect not such a good name) that contains an InitCommandLine method that sets up a TCommandParser instance passing it your TComponenth and help)TCommandParser instance to process the commandline and fill the properties of your TComponent (in my example, this is done in the ProcessCommandLine method).Now comes the fun:
HelpText method that fully automatically assembles a helptext based upon what you fed it with the AddSwitch methods.SaveOptions method that allows you to save the current settings of your TComponent into a settings file.The Delphi units you need are these which you can get from the Embarcadero [WayBack] radstudiodemos.sourceforge.net demo repository:
CommandParser in '...\radstudiodemos.sourceforge.net\branches\RadStudio_XE2\Delphi\Database\dbExpress\Utils\CommandParser.pas',
PropertyHelpers in '...\radstudiodemos.sourceforge.net\branches\RadStudio_XE2\Delphi\Database\dbExpress\DbxDataPump\PropertyHelpers.pas',
ParseIds in '...\radstudiodemos.sourceforge.net\branches\RadStudio_XE2\Delphi\Database\dbExpress\DbxDataPump\ParseIds.pas',Edit: [WayBack] John Kaster wrote a nice [WayBack] article on EDN that includes [WayBack] more details on using the TCommandParser.
Note the above mentioned code mostly is on [WayBack] https://bitbucket.org/jeroenp/wiert.me/src/tip/Native/Delphi/Apps/Console/HiddenExecuteConsoleProject
Since Delphi XE7, this unit does not ship with Delphi any more, but it is still at [WayBack] RAD Studio Demo Code / Code / [r2029] /branches/RadStudio_XE6/Object Pascal/Database/dbExpress/Utils/CommandParser.pas.

It took me a while to figure this one out:
When you have a registered Delphi, you can Ctrl-Click browse both the units and symbols of RTL, VCL, etc. But Delphi will not recompile these units.
Some third party components you cannot Ctrl-Click browse the units or symbols, unless you put the source directory in the Delphi Library Path (which causes them to be compiled each and every time).
This is because:
These are the possible values for that directive:
So please component vendors: when you ship source code, make it IDE-browsable as well by compiling with $YD or $Y+.

Especially when using Delphi 2007 on Windows x64 system (8.x, 7, Vista, 2012 Server, 2008 Server, …), the Delphi specific .Targets files used by msbuild are simply installed to the wrong location.
A better warning for this is in my BeSharp.net repository: Run-Dependend-rsvars-From-Path.bat thanks to David Millington who wrote this:
If you copy
- Borland.Common.Targets
- Borland.Cpp.Targets
- Borland.Delphi.Targets
- Borland.Group.Targets
from
- %windir%\Microsoft.NET\Framework\v2.0.50727
to
- %windir%\Microsoft.NET\Framework64\v2.0.50727
then building via the command line works.
The rsvars.bat file is correct.
Note that my batch file checks for all target file sets:
set requiredTargets=Borland.Common.Targets Borland.Cpp.Targets Borland.Delphi.Targets Borland.Group.Targets
set requiredTargets=CodeGear.Common.Targets CodeGear.Cpp.Targets CodeGear.Delphi.Targets CodeGear.Deployment.Targets CodeGear.Group.Targets CodeGear.Idl.Targets CodeGear.Profiles.Targets if %bdsVersion%==8 set requiredTargets=CodeGear.Common.Targets CodeGear.Cpp.Targets CodeGear.Delphi.Targets CodeGear.Group.Targets CodeGear.Idl.Targets if %bdsVersion%==13 set requiredTargets=CodeGear.Common.Targets CodeGear.Cpp.Targets CodeGear.Delphi.Targets CodeGear.Deployment.Targets CodeGear.Group.Targets CodeGear.Profiles.Targets
