We need a truly immutable typed const.

@Fr0sT.Brutal - Same for records. {$WRITEABLECONST OFF} const TypedConst: xlt = (no:'Norsk'; se: 'Svensk'; en:'English'); type pxlt = ^xlt; procedure TForm1.TestTypedConst; procedure Show(const aConst: xlt); begin Memo1.Lines.Add(aConst.no +', '+ aConst.se +', '+ aConst.en); end; begin Show(TypedConst); pxlt(@TypedConst)^.se := 'Deutsch'; Show(TypedConst); end; Output Norsk, Svensk, English Norsk, Deutsch, English So, the answer is a definitive no. Edit: Note that with WRITEABLECONST OFF TypedConst.se := 'Deutsch'; gives a [dcc32 Error]: E2064 Left side cannot be assigned to while it compiles with WRITEABLECONST ON.

That last point would a major concern. Source code is necessary for third party libs. Are they wrapping some DLL or ActiveX class that is shared across the supported platforms?

I've butted my head against this, and sadly there currently is no way to pass a typed const to an attribute. There are reports for problems with typed consts - so please vote. https://quality.embarcadero.com/browse/RSP-13921 likewise, for dynamic arrays https://quality.embarcadero.com/browse/RSP-32488

https://www.nsoftware.com/ipworks/iot/ supports AMQP 1.0 and 0.9.1 Doc for Delphi: https://cdn.nsoftware.com/help/IOF/dlp/ I haven't tried it. @jeroenp - Did you find a AMQP 1.0 compatible lib elsewhere?

That sounds likely. I stumbled on similar problems with formatting of json strings in other languages when I googled.

Not sure why it would barf on %, but you can replace % with \u0025 (Unicode escape) See also https://stackoverflow.com/questions/19176024/how-to-escape-special-characters-in-building-a-json-string/27516892 What happens if you put a double %% or %25 (Similar to \u0025) or \%

I usually do this as a two pass operation. I first start a thread that fills a memory structure. Once the thread is done, I trigger an update in the main thread that fills the UI from the memory structure. I have nothing but negative experiences with doing UI updates directly from threads.

Your English is fine. Most of the APIs we use, require OAuth 2.0, hence my question.

OAuth 1.0 only?

That is waaay to familiar. As a developer, you never run out of chances to own yourself.

I've had issues with having multiple allocated hWnds and messaging. Ended up with a single allocated hWnd and a custom message broker/router for my user messages.

A company that offers registration tools i.e. licensing tools for developers?

Still unable to reproduce (10.4.2).
