    Unicode weirdness

    It's when you read the output into Delphi that there's a problem. You tool is emitting UTF-8 encoded text, but you are interpreting it as ANSI. The tool is fine. Your code is not.

    DelphiFMX4Python

    That doesn't sound quite right. I wonder if there is another Python somewhere in the system. The only thing in that line of code that looks like a syntax error is the f-string, but they are supported in 3.6. In fact they are new in 3.6 iirc.

    Unicode weirdness

    Isn't the real problem that you have interpreted UTF-8 encoded data as though it were ANSI? I mean, it's clearly not ASCII because none of the characters in your code are in the ASCII set. You can actually delete all of these StringReplace calls by simply using the correct encoding for your extracted data.

    What version of python? You'd get this error with Python 2.

    Pass working delphi code to c++ builder

    FWIW the Delphi code doesn't compile. Always paste code that is known to work, rather than copy it out manually.

    Anyone know why?

    There's an awful lot of anecdote doing a lot of heavy lifting in this thread. I'm seldom persuaded by anecdote. Some thoughts occur to me though. If companies want developers to code in Delphi, but want some body else to train them, then this isn't sustainable. People retire. And then what? Also, I just don't buy the idea that smart talented developers can't learn new technology quickly. We took on a uni placement student this year, who had done two years at uni and no Delphi. They were productive in weeks. And most of the learning was of our code base. I honestly think that if you aren't prepared to take on talented developers and teach them a new language and libraries, then you have far bigger problems as an organisation.

    That's not my experience. But when I hire people I'm looking long term.

    Given your definition of a developer, writing requirements etc, what even is a Delphi developer. Aren't there just developers?

    IsNullOrWhiteSpace???

    It doesn't much matter what anybody expects the design to be. Too late for that now. Given that it takes the string as an argument, and it's a static class method, I think it's safe to conclude that you don't call it as an instance method. Wouldn't it just be better if the language forced you to call it on a class?

    IsNullOrWhiteSpace???

    What is the subject of the method then? What argument are you going to pass, and what purpose does myString serve?

    IsNullOrWhiteSpace???

    Surely it's If string.IsNullOrWhiteSpace(someStr) then like in .net
  12. I'm so confused.
  13. Start exists for a reason. It doesn't exist to create a thread and start it immediately. I still don't know the point of this code. What is the high level overview of what you are trying to do here?
  14. UI code must run on the main thread. Although I have no clue what the point of this code us, I can see that it breaks that rule. Sad to see a thread be created suspended only to be immediately started.

    String literals more then 255 chars

    Yes, but I'd not read your post and was making a general comment to the overall topic.
  16. David Heffernan

    String literals more then 255 chars

    Why just wish for relaxing the 255 limit? Why not aim for multi line literals and more?

    Delphi 11.3 is available now!

    Not the 64 bit windows compiler

    Methods from Libraries (bpl or pas) in Apps??

    I'm not sure that @programmerdelphi2k is correct here. Consider RTTI. The compiler / linker can strip any code that it knows cannot be called. But with RTTI code can be referenced in ways that are only known at runtime. Therefore any code that can be reached by RTTI cannot be stripped.. Even if the linked knows, through static analysis, that it cannot be called directly

    memory paging or segmentation

    It's almost impossible to help you

    TNumberBox and scientific notation (exponential format)

    What's wrong with a simple edit control?

    memory paging or segmentation

    because SizeOf(Char) = 2?
  22. David Heffernan

    memory paging or segmentation

    Write a program that does Writeln(SizeOf(Char));
  23. David Heffernan

    memory paging or segmentation

    The pascal code in the question has pointer access and arithmetic
  24. David Heffernan

    memory paging or segmentation

    What is SizeOf(Char) on your system. If it is 2 then that would explain everything.
