Perhaps a little rework into a record will remove the whole question of the absolute directive completely. So that you get the point of the additional benefits I see from such structure, to have much more related informations included and easy extendable. This way you can use the right types for specific fields, not all as strings. unit PeriodicTable; interface uses System.SysUtils, System.Math; { TElementRecord encapsulates properties of a chemical element } type TElementRecord = record AtomicNumber : Integer;

Nice. To handle it more effectively, I would encapsulate this const array in an Enum with a record helper. That allows to add a lot of convenience functions around this table and offers a nice and effective Enum handle.

Interesting question. Feasibility with Hooks: - Key Hooks (WH_KEYBOARD_LL): These are irrelevant for detecting paste operations, as pasting is typically triggered via mouse or context menu, not keyboard shortcuts. - Global Mouse Hooks: These can detect right-clicks but cannot reliably identify the "Paste" command or the target directory. - Shell Hooks (HSHELL_*): Using SetWindowsHookEx with WH_SHELL or registering for Shell notifications (SHChangeNotifyRegister) might provide some context about Explorer actions, but they do not directly expose paste events or destinations. Alternative Approaches: - Windows Shell Extensions: Create a Shell Extension (e.g., a context menu handler) to intercept paste commands in Explorer. This requires injecting code into Explorer’s process, which is complex and may have security implications. Maybe that could work for you, although it interferes too much with Windows systems for my taste.

Thats a fair move. Videos are not so easy to be changed https://youtu.be/77bQ6Xs0kBE?t=2598 So I hope that at least some core BLE improvements were still visible.

This depends a bit on what you really need to test in your app. If you want to test all kinds of dynamic hardware stuff a phone can do, then I would always recommend a real device. Only that can behave truly by accleration/motion/orientation sensors, touchscreen, phone calls, etc., the simulator can only roughly simulate that. If your app is mainly a "form" app with controls, not using a lot of specific hardware of the phone, then the simulator could be good enough for you. As far as I know, the debugging doesn't work under iOS simulator too, but still under Macos. So it is always a good idea to test under Windows/Macos first, and only then check the "view impression" and handling by iOS simulator or device.

Thats easy to solve, you just have to patent your prompts then

How can that happen, also I have seen this note about MTU in many "whats new" references from Embarcadero and looking forward to this. I'm not yet on 12.3, is this really missing in the source codes, or is it just defined for some platforms?

Thanks for sharing. You are still on Parallels Desktop 19, while there is already 20 out, is there a specific reason? https://kb.parallels.com/en/130212/ I'm quite sure that they have done a lot of performence improvements in this new version too, would be great see your direct comparison for this too in the future.

I also understand the urge to have such handy property, for convenience. On the other hand, if I consider the DataSource as part of the view and the Dataset as part of the model, perhaps there is a good reason to hide it here, so that the model doesn't know about its views.

Yes, I agreed to this already 10 thread posts before. I only asked if anybody already looked into it and/or tested against it. Any terms within the former sentence may start further massive nitpicking, I know. Nevermind, it's OK then for me.

Mindful misunderstanding of other peoples Intention and expressions is also a Form of Art.

Yes you are right. VCL/FMX unit linkage is comparable to DB and Windows-Service. Also tests for other platforms are completely superfluous, especially if Win32 ASM code is used in the library, nothing can go wrong here. I revoke all my silly notes above, they seem to be too stupid.

Excaclty, it should not ... Thats why I asked, if its tested against those and ensured that no hidden UI units are linked or involved. I think everyone can very well understand the meaning of my question here, even if VCL/FMX mentioned. There are too many VCL-only libraries out there. But thanks for your clarification.

Peeking into this nice library, it seems pretty much multi-platform compatible to me, even if there were some encapsuled Intel ASMs inside. Nevertheless, it seems to be specified only for x86 basically. Have you tested this under VCL, FMX, Win32, Win64, Macos (x86/ARM), iOS, Android, Linux as well? Would be great to know, if this is fully supported under all Delphi platforms, maybe it was already tested against these?

Flicker? Is that the case under VCL? Maybe this is interesting for setting per control https://blogs.embarcadero.com/vcl-per-control-styles-coming-in-rad-studio-10-4/

If indentation is your main focus, then I would suggest to port an large ERP system first into Python, keeping the indentation 99% valid, and then later port this from Python to Javascript and modern web technologies. This makes things much easier and I think this is the way DOGE is looking for.

You could use a setter for sQuery, that sets up the SQL before showing the form. That would not nee FormShow.

Perhaps they already have better AI than you and me 🤔

Thanks, this is a great library and introduction. Can your libFPC also be configured to generate and run an Pascal code in memory at specific periodic schedules, lets say like every 1st of April or so?

Yes, good choice too, but I would prefer a slightly more modern PC, like the Sinclair ZX81 Basic language: https://github.com/andrivet/zx81-typescript-emulator/blob/master/Documents/Sinclair ZX81 BASIC Programming.pdf This is at least an evolved high level language, whereas RPG is probably not. Also the vast amount of memory in this product makes it mode suitable for modern 3D and AI tasks, IMHO.

Yes, of course. My consideration was that Macos & Co might have their similar credential API worth to abstract then here under one umbrella: Nevermind, thanks for clarification.

Thanks, nice piece of code. 👍 I have two questions: 1. You keep the secret as String in the class, wouldn't it make sense to hash it, so that at least not a simple memory dump might offer a readable password? 2. You're implemented Windows-specific, are you going to implements other platforms too ( it looks a bit like that ) ?

I'm not on D12.3 yet, but 12.1 + Patches, and I've made some tests with TThreadedQueue in the past, finally moving to Spring4D. Another useful technique for your decision could be, try to grep where this class is used in other projects or libraries: - I only find one occurence in Datasnap.DSServer. This seems not to be a well tested class yet, IMHO.

Hi there, I'm trying a bit with with custom records and have here some minimal example. Its about the API to work with such records. I wonder what will be the right way, to use it in the following scenario, without warnings: unit UMyCustomRecordDemo; interface type TMyCustomRecord = record public type TMyEnum = ( meFalse, meTrue ); private FValue: TMyEnum; public // Standard-Operators for Custom Managed Records class operator Initialize(out Dest: TMyCustomRecord); class operator Finalize(var Dest: TMyCustomRecord); class operator Assign(var Dest: TMyCustomRecord; const [ref] Src: TMyCustomRecord); // Factory-Method, which shall prepare a new record, that can be used with inline variables and intrinsic type evaluation class function Make_Record: TMyCustomRecord; static; end; implementation class operator TMyCustomRecord.Initialize(out Dest: TMyCustomRecord); begin Dest.FValue := meFalse; end; class operator TMyCustomRecord.Finalize(var Dest: TMyCustomRecord); begin // Finalize if necessary end; class operator TMyCustomRecord.Assign( var Dest : TMyCustomRecord; const [ref] Src : TMyCustomRecord ); begin // Simple copy of internal values Dest.FValue := Src.FValue; end; class function TMyCustomRecord.Make_Record : TMyCustomRecord; begin // This shall prepare a new record Result.FValue := meFalse; end; end. And it would be used like that procedure TestMyCustomRecord; var LRec1: TMyCustomRecord; begin // This assignment throws the warning: W1048 Unsafe typecast of '%s' to '%s' (Delphi) //Yes, it may be caused by temporary object and assignment, which is not most performant. LRec1 := TMyCustomRecord.Make_Record; //I would like to use this, as elegant way to make and prepare a new variable var LRec2 := TMyCustomRecord.Make_Record; end; My question is, are CustomManagedRecords not intended to be used in Function results, because there is no nice easy way to get rid of these warnings? How about functions returning Records in general, this is not the most efficient way, I know, the pro's are its readability. Would there be an elegant way out of this problem (maybe by records using classes or smartpointers internally, but would such overhead be worth it for simple records? And yes, I know that a "getter" would solve it, but not as elegant as above API: TMyCustomRecord.Make_Record( LRec );
