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

Today I ran a test to see which is the best way to compress Delphi projects for backup/archive purposes. The contestants are Zip, WinRAR (v7.01) and 7Zip (v24.08). I expected WinRar to be the winner in all cases (as usual) but for plain text files (PAS), the results were surprising. 7Zip won! TEXT COMPRESSION Original

01.2023 Some of my programs need to run as single instance. This means that if an instance of my program is already running and the user is trying to start another instance, the second instance should not run. However, before closing the second instance, I want to pass the command line parameters from that second
Somebody asked me: can you tell if the machine on which you are running is a virtual machine installed secretly by some malware/hacker? I thought about that question and the answer is SURE. Without any doubt. A virtual machine will consume some resources by itself (quite a lot). If you observe these missing resources you

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;

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.
