    [out] and [in] in records

    In modern Delphi you can do that like this: TMyRecord = record private FSrcPosition: TPoint; function GetDestination: TPoint; public property SrcPosition: TPoint write FSrcPosition; property DstPosition: TPoint read GetDestination; end;

    serious bug with Indy based code and I9 8/16 cores

    Standalone web servers is not a common type of projects for Delphi. That is why default memory manager was not tweaked for such load. But full version of FastMM4 has lots of different tweaks specifically for multi-threading, so you can customize it as you wish.

    New project with embedded browser

    If you only need to display HTML written by yourself, then THtmlViewer might be an option.

    Conceptual - callbacks that are called from background thread

    Your TСompressor.Create runs in current thread, so you can easily store it as CallerThread. Then, in decompression thread, you can synchronize to CallerThread instead of main GUI thread.

    handling predicate conditions

    It is almost the same as Assert(value <> nil, 'Value is nil!'); Assert(str <> '', 'String is empty!'); Assert(Value.Num > 0, 'Value.Number <= 0!');

    looking for design ideas for an easily editable list

    This is, probably, the simplest possible solution, if you limit yourself to "out of the box" solutions. By the way, TClientDataSet can be replaced with TFDMemTable.

    Generic Command Line Parser for Delphi 10.3.x

    I was expecting to see at least built in support for "--help" and "--version". As it is now, it is not much different to FindCmdLineSwitch.

    WinAPI to query if a form is ready to Rock.

    We had similar problem, except, that we wanted to know, when app finishes processing any long task, and is ready to accept new input. And we wasn't allowed to change the code of the app. Our first attempt was to use SetWindowsHookEx in WH_FOREGROUNDIDLE mode. That was working in most cases, but sometimes we had situations, when the last message in the message queue is actually the one, that causes processing of long task, so our hook was triggering at the beginning of the processing, not the end. Also, this hook will hang until some message will get in to message queue, so some sort of wake up message is required. Finally we decided, that since target app uses runtime packages, we can call VCL for help. Now our test app is using windows hooks only to inject our code (dll compiled with runtime packages) in to target process. Then we create event handler for Application.OnIdle. This approach is much more reliable, something like 95%. If you can change the code of target app, then it will the best approach. P.S. You could avoid all of that, if VCL supported UI Automation

    Lots of errors when trying to compile an old project

    Try to toggle compiler cache on and off: http://docwiki.embarcadero.com/RADStudio/Rio/en/Compiling_and_Running

    Refer to Form Control without using the Form unit?

    You of course know, that you can break some cycles by moving parts of uses to implementation section, right?

    Delphi 10.3 Update 2 available

    Try to install Xcode on your Mac. I think, reading the log will be much easier: http://docwiki.embarcadero.com/RADStudio/Rio/en/New_features_and_customer_reported_issues_fixed_in_RAD_Studio_10.3.2

    Delphi 10.3 Update 2 available

    Looks like I can download fresh ISO from torrent, but I need hash sum to be sure, that it is correct file. Can someone post your sum here? MD5 will be enough.

    ANN: StyleControls VCL with Fluent UI background support just released!

    What API are you using? As far, as I know, Acrylic Blur is not documented for classic Win32 apps. And using undocumented API is not a good idea.

    LiveBinding at runtime

    You will need to manually call TBindings.Notify because your controls are not observable: http://docwiki.embarcadero.com/RADStudio/Rio/en/Tutorial:_Creating_LiveBindings-Enabled_Components As to why even manual call does not work, it is hard to tell without compilable demo.

    LiveBinding at runtime

    Maybe, you should try Bind(srcViewModel.Container,'DataSource',dstDBGrid,'DataSource') ? But in general, this looks suspicious to me. Usually LiveBindings are used to replace data-aware controls, and you are trying to mix them. What do you want to achieve?
