“AI-Assisted Development for Delphi” is the fifth book in the “Delphi in All Its Glory” series. Released April 2026. Why This Book Exists There are a gazillion books about AI out there. This is the only one written for Delphi developers. Your LinkedIn feed says programmers will be obsolete by next Thursday. Meanwhile, you’re […]

Using Claude Code for Delphi — What I Learned Writing a Book About It What started as a frustrated blog post became a 280-page book. Here’s the story. In early 2026, a post on Delphipraxis claimed that one hour of development with Claude Code was worth a full day of solo programming. Bold claim. I
“Free Code Agent: Build Faster Right in Your RAD Studio IDE” Presented by Yai (CTO at Solutions, Embarcadero MVP) Core Idea * AI Code Agents are tools that accelerate coding tasks by generating, refactoring, and scaffolding code inside your IDE. * They do not replace developers; they augment productivity. * Example used: Gemini CLI
Locating BPL dependency failure In one instance my package required another package, but its BPL was not present. The error I got was “Can’t load package xyz.bpl. %1 is not a valid Win32 application”. I used the Dependency scanner feature from ‘PE Explorer’ ( www.heaventools.de ) to detect this. There was supposed to be a

I was undecided if I should attend to this conference or not because I didn’t have enough information about the previous one. So, here is my 2.5 cents. A Journey by Bicycle Setting off in early June from Denmark on two wheels, I pedaled a few hundred km for the Delphi summit. The northern weather

In FMX, unlike the VCL, the Visible property affects both design time and runtime when set in the Object Inspector. That’s why setting Visible:= False in FMX hides components in the Form Designer, which is a big inconvenience. If you edit the form at design time often, you can keep Visible:= True in the designer
Under FMX, TComponent.Visible effects also the design time! Read More »
VCL had a nice and uniform message box system. Most important (and convenient), the messages were blocking. Because of the Android platform which does not support asynchronous messages, all this is gone. So I document here the behavior of few different ways in which we can display message boxes in FMX. None is perfect (not
IDE Removed deprecated features: VCL Translation Support & Modeling Object Inspector – New string list editor Multiline string Editor Multiline string literals The Find in Files dialog now has a new Subdirectory exclude mask option, which excludes specific folders from being searched when using the Search in directories and Include subdirectories There are default exclusions
So, because I built a program that has to resize/scale images up and down, I built this tool to test 13 resizing algorithms for Delphi. Tested algorithms JanFX SmoothResize JanFX Stretch Transform (from Graphics32) HB (Private) madGraphics (from madShi) VCL.ScaleImage (from Embarcadero) VCL.Stretch (from Embarcadero) SmoothResize (assembler) Windows Thumbnail (Windows API) Windows StretchBlt (Windows API)

Note: This article is tightly connected to the “How to correctly set the compiler options” article. Somebody asked how to set the default project options for a new Delphi project. I stopped years ago wasting time with this. Instead I have a folder where I store a “template” project. You can find this Delphi

I needed to open PDF files in Delphi. There seems to be a lot of libraries out there, but when my restrictions (read PDF, native Delphi code, cross-platform, acceptable price) started to kick in I realized that there are not so many options. I created therefore this Delphi PDF library comparison table to help me
Note: This page is an excerpt from my “Delphi in all its glory – Libraries” book. $(Auto) is a new environment variable, introduced in Delphi 10.4. Embarcadero didn’t make a big show around it so it went unnoticed by most programmers. But don’t ignore it! It is extremely useful for packages, where it can
My Experience with Cursor: The Promise and the Reality 2025.01 This week, I had the opportunity (or perhaps the misfortune?) to try out Cursor, a new tool that promises to enhance productivity for programmers. As someone who primarily works in Delphi, I was curious to see how it would stack up. Cursor is an AI-powered
The Delphi in all its glory book shows that at design time the IDE is the host of all visual components on our forms. If a single control misbehaves at design time it might take down the whole IDE. In most cases this happens while we drag and drop such components from Components Palette on
KSDev released this year CrossVCL – a framework that allows you to build multi-platform applications. What is the difference between Firemonkey and CrossVCL? If you want to make your current app multi platform, you need to port it to Firemonkey. With CrossVCL you don’t need anything!!! They really upgraded Delphi/C++ programming to a brand new

I recently observed that Setup files created with WinRar have a high false positive detection rate from antiviruses. Here are the conclusions of some test I made, in order to reduce the false positive rate: RAR version SFX module Detection ratio WinRar 3.11 32bit 1/66 WinRar 4.2 32bit? 3/66 WinRar 5.50 32bit 6/67 WinRar 5.50

I stepped last week in a multiple-bug situation with EurekaLog for Delphi. I again wasted MORE than a day with this buggy “exception tracer tool”. My DRP file is like this: PROGRAM MyProgram; uses {$ifdef win32}fastmm4,{$endif} EurekaLog_units_come_here This worked fine until I compiled the program to 64 bits. On 64 bit, EurekaLog refused to work.
Most of my Delphi programs are flagged as virus by some antivirus programs. Some of these antivirus programs are really cheap/under-the-table products (such as Baidu and Comodo) other are big (TOP) name like Kaspersky. In theory you should report a false positive to the antivirus producers so they can fix their bug but if the

Today I needed a function that will wrap a string (a contiguous block of characters with no spaces) after 80 characters. Not only that I have found SysUtils.WrapText unsuitable (it can only wrap text IF the text contains spaces) but it is also terrible slow. So I build my own function: function WrapString(CONST s: string;

After spending 2 full hours I managed to find the culprit for an IDE crash (access violation in VCL210). The cause was …drum roll please… CnPack! There was a palette in IDE’s main tool bar called MSDN Help. However, when I right click to configure the toolbar, the palette was not listed there to show

Today I tried to open an old project. While loading the main DFM form I got a “No mapping for the Unicode character exists in the target multi-byte code page” error. After some time I figured out what caused it: the form had a custom control that had a property like this: HeaderCellSpacing = 1.300000000000000000.
