    Why is TList freed in this code?

    Oh, good to know it honors its name

    Why is TList freed in this code?

    So, how does it behave? never used it

    Why is TList freed in this code?

    So, the doOwnsValues frees the objects in assignments as well. I thought it only takes care of them when the dictionary is freed. Thanks a lot guys

    Why is TList freed in this code?

    Hi, I've got difficulties figuring out what is wrong with the following code: program Project1; {$APPTYPE CONSOLE} {$R *.res} uses System.SysUtils, System.Generics.Collections; var dic: TObjectDictionary<string, TList<string>>; list: TList<string>; begin try dic:=TObjectDictionary<string, TList<string>>.Create([doOwnsValues]); list:=TList<string>.Create; list.Add('111'); dic.AddOrSetValue('aaa', list); var gg: integer:=dic.Items['aaa'].Count; writeln(gg); // 1 var l2: TList<string>:=dic.Items['aaa']; var a:integer:=l2.Count; writeln(a); // 1 l2.Add('222'); a:=l2.Count; writeln(a); // 2 dic.Items['aaa']:=l2; a:=l2.Count; writeln(a); // 0??? a:=dic.Items['aaa'].count; writeln(a); // 0??? dic.Free; // Invalid point? readln; except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end. When I assign the TList to the dictionary Value, it loses all the elements. What am I doing wrong here? Can't see what is going on. Thanks

    FMX TWebBrowser Security Error

    I use TWebBrowser and trying to login to an email account. After the initial page, I get an error saying that "The browser or app may be insecure. Try using different browser". Does anyone know how to fix it? I read on the net that I can change the User Agent header to reflect a newer browser but couldn't find how to change the header in the component. Thanks

    How to implement Push Notifications?

    Hi, I want to implement push notifications in a desktop app for GMail. I have read the dev guides and looked it up on the web and I all tutorials talk about how to do it in web apps. My email client on Android uses push notifications. Can anyone guide me on this? Or, any demo apps, perhaps? Thanks

    ANN: Better Translation Manager released

    Yes, I was sure that other platforms wouldn't be easy to work with. Thanks for the tips.

    ANN: Better Translation Manager released

    HI, Thanks a great app. Thanks for the contribution. I've got two questions: 1. Does the translation work in FMX apps? 2. Is there a way to load a resource file at run-time without the need to restart the translated app? Thanks

    Are we just "Cash Cows"?

    In my view, the problem with Emba in relation to Delphi (and perhaps to C++ Builder) is not a problem of resourcing and funding. It is mainly a problem of mindset

    Book: Delphi Quick Syntax Reference

    Apart from the additions in 10.3 and 10.4 I found very difficult to track down and verify this information and then to present everything in a concise way. And I am not sure a newcomer would really find this useful. Perhaps if you write components and need to cover old versions this would be useful but I feel this is a bit out of the scope of the book.

    Book: Delphi Quick Syntax Reference

    I can't insert an image in the post now. So here's a link https://www.amazon.co.uk/Delphi-Quick-Syntax-Reference-Language/dp/1484261119
  12. Hi all, I'd like to share that my new book is almost out. Apress is working hard to put it in the market. We always discuss how we can bring new people to Delphi so I thought it would be a good idea to ease their way in by providing a quick up-to-date guide on the basics of the language. The book covers new features introduced in 10.4 Of course, a reference book is always useful to experienced coders as well; we all need a refresher every now and then 🙂 I would like to cordially thank Dr. Holger Flick for reviewing the chapters; his experienced view guided me during the writing of the book. Regards, John 9781484261118.tif

    Client Library for FusionAuth?

    Hi @Dan Moore, I ended up writing my own. It does not provide full cover of the API; I only added the calls I needed. I can share it with the community but need to clear it up a bit as at the moment it uses some proprietary code. I only used it for simplicity but it can be replaces with open source. Thanks John

    Drag and Drop Component Suite for Delphi 10.4 Sydney

    Interesting...I am going to have a look at it. Sadly it does not support FMX apps

    Hints and ShowHint

    @Anders Melander Are you sure ShowHint is inherited from the parent control? Shouldn't it respect the HitTest property?
