Since none of us are mind readers, a description of what you want to achieve could be useful. What action should lead to what effect, and when?

That is unfortunately correct. As mentioned above - if you avoid creating Json that embed container data outside your control, you will avoid such issues. Json as per example above { "result": [{ "Id": 10, "Name": "Einlagern" }, { "Id": 30, "Name": "Umlagern" }, { "Id": 400, "Name": "Kundenbarcode" }, { "Id": 100, "Name": "St\u00FCckgutverladung" }, { "Id": 400, "Name": "NVE zu Kundenbarcode" }, { "Id": 0, "Name": "" }, { "Id": 0, "Name": "" }, { "Id": 0, "Name": "" } ] }

Duh! It's the TStringList that has changed... To avoid situations like these, you should build Json that does not embed information that belongs to the container. F.x. type TStatus = class private FId: Integer FName: String; public constructor Create(const aId: Integer; aName: String); function DisplayText: string; property Id: Integer read FId write FId; property Name: String read FName write FName; end; TStatusArray = TArray<TStatus>; constructor TStatus.Create(const aId: Integer; aName: String); begin Id := aId; Name := aName; end; function TStatus.DisplayText: string; begin Result := Id.ToString + '|' + Name; end; function tmyServerMethods.Load_Scanning_Functions(vuserid:longint):TStatusArray; var i:integer; begin result := []; // data is a query ... for i:=1 to vdata.recordcount do begin result := Result + [TStatus.Create(vdata.fieldbyname('statusid').asinteger, vdata.fieldbyname('statusname').asstring)]; vdata.next; end; end;

That was a very weird difference. It looks like the types of Fencoding and FDefaultEncoding has changed. Can it be that the type you intend to use is being "replaced" by type with the same name, due to a scope issue?

Can you describe in what way the Json encoding differs? Json examples would be good! Even better would be small self-contained compilable example that demonstrates the difference between 10.2.x and 10.3.x

Doesn't GetIt die horribly if you disable theming, or did they fix that?

You can pause the VMs so that they use zero CPU. Unpausing is near instant. They will still use memory, though.

The devil is indeed in the details.

VirtualBox is really nice for making test VMs for Windows and Linux. Install your favorite Windows version in a clean VM. Hotfix it and adapt it to your liking. Clone it. Install 10.3.2. Snapshot it. Clone the original again. Install 10.3.3. Snapshot it. Voila! Side by side comparison is now possible.

If I had to use Synchronize, I'd only use it to trigger an update in the UI. TThread.Synchronize(nil, procedure begin RefreshTimer.Enabled := True end); and perform the actual update in the timer event handler. I have had so many bad side effects with Synchronize, that I simply prefer to not use it at all.

Delphi.Owner; 😛

I tested building all our code, and luckily no surprises there. Delphi 10.3.3, TMS 9.03, Eurekalog 7.8.1. Actually running the code is next 😛

https://eurekalog.blogspot.com/2019/11/black-friday-and-cyber-monday-sale-2019.html If you deploy Windows apps to clients, tools like Eurekalog and MadExcept are indispensable for information about what goes wrong and where, when your users get an unhandled exception. Disclaimers: We use Eurekalog. We do not get referral discounts.

That makes me assume there will be no new Community Edition until 10.4.0 I was wrong about this.

Was there a 10.3.1 or 10.3.2 Community Edition?

Low(Integer) - assuming 32-bit Integer - will always be -2,147,483,648 What value were you expecting to see? Zero? Then you need to use Default 0 - or type Cardinal instead of Integer. Note that using a Cardinal can introduce challenges with regards to math operations that may cause a signed result such as (Small.Minvalue - Big.MinValue) < 0

My preferred way of dealing with sub-tasks is to provide a "mailbox" i.e. some sort of container, like a queue, array or list, for them to insert their results in. The main thread can either poll the mailbox periodically, or you could use a message or signal to initiate the polling whenever the container has content added.

Our servers rarely run with less than 25 concurrent threads. We also have threads that can't run in parallel and a scheduler in place that ensures that it doesn't happen. Have we had problems? Sure, when we broke the rules. Threads are not more dangerous or hard to use than any other field of development you are introduced to. The hardest thing about multithreading is to adapt your thinking to asynchronous events, instead of sequences.

It seems that the French has a "times 20" system that is somewhat similar to the Danes.

For my last questions - I was wondering whether removing a beacon from the manager, or stopping/starting the manager helped for redetecting the first detected beacon?

What is the format of the text message itself, i.e. not the attachment, but the body of text? If HTML - does it contain: <meta charset="UTF-8"> If XML - does it contain: <?xml version = "1.0" encoding = "UTF-8" ?> If plain string - Do you explicitly transform the string from the internal unicode string to UTF-8? I also stumbled on this: https://stackoverflow.com/questions/40469867/message-rfc822-ignores-utf-8 See last comment by @Remy Lebeau

My guess: String encoding. Explicitly setting to UTF-8 wherever possible should cure it?
