    Delphi 64 bit Registration Tools for Windows Apps

    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
  2. 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
  3. There are quite a few Excel components available but I can't find any component to generate a PowerPoint presentation file. I realize I can possibly do this via OLE automation but that seems a little "flaky" to me. Does anyone know of a such PowerPoint component? Thanks, Steve
  4. Thanks Remy — yes, I've take a look. The examples are threadbare to say the least. Steve
  5. 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
  6. 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

    Delphi 10.4.2 first impressions

    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
  8. So it's a speed thing. Thanks!

    Delphi 10.4.2 first impressions

    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
  10. 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

    NERO5 chess engine

    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.

    NERO5 chess engine

    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

    Outdated Delphi Roadmap

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

    GExperts 1.3.17 experimental twm 2020-10-23 released

    Brilliant! Thanks for this.

    Outdated Delphi Roadmap

    It's a roadmap not a punch-list!

    Outdated Delphi Roadmap

    Maybe something special is brewing! If I had to guess maybe it would be RAD WebAssembly
  17. 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

    "Debug process not initialized."

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

    Any Known Issues with ZCompressStream?

    My application saves data as a compressed JSON file. I use the standard System.ZLib routines ZCompressStream and ZDecompressStream to handle the compression. I thought these were just a wrapper around standard ZLib routines. Earlier today someone sent me an application file that couldn't be opened. It turns out it couldn't be decompressed. It could have been corrupted after being saved. The decompression routine went into some sort of endless loop when it attempts to open the file. My question is: does anyone know of any problems compressing data using ZCompressStream? I'm using Delphi DX 10.4.1. Are there any other third party ZLib compatible compression and decompression routines? Steve

    Any Known Issues with ZCompressStream?

    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.

    Any Known Issues with ZCompressStream?

    That was a question I had — why wasn't there a checksum error when it tried to decompress?

    Any Known Issues with ZCompressStream?

    Thanks David — all good advice. I was really looking to see if there were a list of known bugs with the ZCompressStream. It seems file corruption post saving is probably the most likely explanation.

    Any Known Issues with ZCompressStream?

    Thanks — I wasn't aware of System.ZIP2. I'll take a look - Steve
  24. Are we due for an updated Delphi roadmap?
