I have a popup menu on a TPaintBox. Up to now I've used the simple code: PopupPoint := PaintBox.ClientToScreen(X, Y); RadialMenu.Popup(PopupPoint.X, PopupPoint.Y); It seem this doesn't work on multi-monitor systems — the Radial Menu isn't visible after the popup and the user thinks the application has crashed. How do I adjust this so it works with multiple monitors? Thanks! Steve

Hi Remy, I'm using Delphi 10.4.2. We have been unsuccessful in replicating the problem, although I did see it for myself on a Zoom call. At this point I'm going to move on and class it as a strange setup issue. Thanks — Steve

I don't have an extra monitor but a colleague has one so we're trying to reproduce. It seem the problem occurs in a configuration of two monitors above the main screen / laptop screen.

Thanks Remy, I am actually passing a TPoint (my error when creating the code example). The user is reporting that the application crashes when they right click, and it's corrected when they only have one monitor. Does ClientToScreen work in all cases when the extra monitor is above, below, left and right of the main screen? Steve

I found this but it seems to be FMX and, I should have said, my application is VCL. But thanks — Steve

Hi Felix, For those unaware of the subject area, I assume you're talking about the chess engine Stockfish. You're going to need to run a console app (stockfish) and then capture the output. For VCL apps you can use DOS Command. It's in GetIt. I'm not sure of this is available for Firemonkey. I hope this helps. Steve

We use OnGuard. It's free and in the GetIt repository. It works perfectly and we haven't been cracked (although our application is not a mass-market consumer product) Steve

I need to read and parse a large JSON file (of geographic data) as fast as possible. I'd prefer to use Delphi's own classes but I'm not adverse using a third party component if it's measurably faster. What's the best way to do this? Thanks, Steve

Thanks Remy — yes, I've take a look. The examples are threadbare to say the least. Steve

I've added a TNotification to my application. After it completes a relatively computationally intensive task it creates and displays the notification using the following code: //-- Create it xNotification := NotificationCenter.CreateNotification; try //-- Process if assigned if assigned(xNotification) then begin xNotification.Name := 'Optimizer'; xNotification.Title := 'AlignMix AI Optimizer'; xNotification.AlertBody := IntToStr(OptScope.TerritoryCount) + ' ' + Project.Alignment.Territory.TerritoryNamePlural + ' created in ' + FormatFloat('#,##0.0', StopWatch.ElapsedMilliseconds / 1000) + ' seconds'; NotificationCenter.PresentNotification(xNotification); end; finally xNotification.Free; end; However, when the EXE is run for the first time outside the IDE the notification has a rather odd caption "Embarcadero.DesktopToasts.02911170" (see image attached). On subsequent runs it has the executable name, minus the ".exe" extension (see image attached). How can I customize the notification caption? I'd like it to simply say "AlignMix" Thanks, Steve

I have a confession: I'm terrible at ensuring there are no Hints or Warnings in my code. That's all got to stop now that I have switched to 10.4.2 — the IDE now scream at me to fix these Hint and Warning (that's a good thing)! One hint that crops up a lot in my code is H2443 Inline function. Typically it says something like: H2443 Inline function: TOptimizer.Execute has been expanded because unit 'TAnneal' is not included in the USES list What is this all about? Clearly the code runs without TAneal in the USES list and I like to minimize the number of units in the USES list. The hint goes away if I add TAnneal to the USES list but what's the advantage of including it — my code is cleaner and runs just fine if I don't include it. Also, does anyone have a tutorial on getting rid of Delphi Hints and Warnings? Some are obvious, others (like this one) are not so obvious. Thanks, Steve

Hi David, Does your app target Win64 or just Win32? My Win32 component path was fine, it was my Win64 component path that was scrubbed. Steve

So it's a speed thing. Thanks!

Thanks!

As I posted elsewhere, the new install scrubbed my Win64 library path. That was the only problem I encountered. Overall it seems like an excellent, quality orientated upgrade. I ran my mapping application through some speed tests and it definitely seems to be running faster when compiled with the latest version — about +4% faster. Steve

I made the mistake of updating as soon as it was released. After installing (all default option) I found it had scrubbed my Win64 component path. The Win32 path is in tact but it'll be a right old pain to manually copy between the two. Also had to re-install OnGuard and Konopka components via GetIt (a modest pain). Be warned, Steve

Deep Blue was IBM’s pet project from the late 90’s and has never been available for public scrutiny. It’s estimated strength is about 2800 ELO. To put this in context, if the latest Stockfish, running on a iPhone, played 100 games against Deep Blue it would win at least 95.

I'm reasonably well know in the field of computer chess and competed in the 2015 World Computer Chess Championships. Although Delphi is my first language, my engine was written in plain old "C". However, there are a number of strong open source chess programs written in Delphi. Here are a few: Booot: booot6_4_release.rar (dropbox.com) Open-Critter: GitHub - rchastain/open-critter: UCI chess engine written in Pascal by Richard Vida Durandal: GitHub - rchastain/durandal: UCI chess engine written in Pascal Steve

One aspect I appreciate is some attention to the compiler's output. It seems 10.5 will finally get some floating point optimization!! Steve

Brilliant! Thanks for this.

It's a roadmap not a punch-list!

Maybe something special is brewing! If I had to guess maybe it would be RAD WebAssembly

If I run my application in debug mode and then exit the application, I get a small dialog informing me "Debug process not initialized" — see screenshot. I then have two buttons: "OK" and "Details". When I click "Details" I can see the MadExcept error report. I can't see anything obviously wrong. Does anyone know how to fix this? All help appreciated! I'm using Delphi DX 10.4.1 Steve bugreport.txt

I disabled MadExcept IDE exception catching and that didn't fix the problem. It was a good idea. Thanks — Steve

I won't change my library but I'd still like to be aware of any newer, and maybe better, libraries. Having had a quick look it seems to be third party. I had thought it was shipped with Delphi since it was System.Zip2. I try to minimize the use of third party components so definitely won't switch, or even look any further.
