    Find exception location from MAP file?

    madExcept, EurekaLog, etc. are the best ways to do this. But obviously you don't have that yet, so you can just subtract $00401000 from the address and look up that value in the Publics by Value section of the map file.

    TestInsight 1.2 released

    Congrats to both of you
  3. I don't get this. If you don't have any particular needs, then I don't see how anybody can offer suggestions. And if all you want is a list of libraries, then websearch will get you that. Do you know what you are going to do with these random numbers?
  4. What properties are you looking for. The reason that there are many different algorithms in use is that different applications have different requirements.

    Delphi books

    When you buy ebooks you are granted rights to read the book, not to send to others.

    Not all free. Pretty galling for any of the authors of these books to read this post.

    It depends entirely on what you want to learn about.
  8. Your way makes it impossible to pass an empty array. If an empty array is never valid, then fine. If an empty array is supported then the Pointer cast is preferable.
  9. The reason I prefer Pointer(data) is that it doesn't trigger range check error if the array has length 0.

    Pos

    Start goes with finish, begin goes with end for nouns at least. For verbs start and stop are pairs.
  11. David Heffernan

    Pos

    Yeah, this is much better. And a good matching pair too.
  12. You need to specify the calling convention, probably cdecl. And I'd declare it as PInteger and pass Pointer(data).
  13. David Heffernan

    Pos

    I think start should pair with finish, begin pairs with end, from pairs with to, etc. Don't really like start paired with end.

    ofc, the naming of TrimRight is a bit of a slap in the face for Arabic speakers and other RTL languages!!! Should really be TrimEnd and TrimBeginning or something like that...

    Pos

    TrimRight is what you want
  16. Yes. You have to declare a pointer type.

    Bug in Android32 compiler

    All I am saying is that you don't need to special case INFs for comparison.

    Bug in Android32 compiler

    You don't need to do anything with INFs, they compare exactly as you'd expect.

    Bug in Android32 compiler

    Not a bug. All comparison operators return false when one of the arguments is NaN. https://stackoverflow.com/questions/1565164/what-is-the-rationale-for-all-comparisons-returning-false-for-ieee754-nan-values Also, bug reports are best at Quality Portal. Although not this one, because it's not a bug.

    64bit Debugger Not Handling Memory Problems

    That's exactly the error I'd expect and the debugger will break at the line of code that accesses the uninitialized pointer. None of these tools will make much difference to this sort of debugging. You just need a slightly better understanding of how memory errors manifest and how to let the debugger tell you what's wrong.

    Delphi 5 Printing

    Well, how are you printing at the moment, if not using GDI? And GDI printing must be like 30 years old now.

    Is a "bare-minimum" EurekaLog possible?

    Yes, this is precisely what I currently do

    Is a "bare-minimum" EurekaLog possible?

    Encrypting the map file, and then decrypting on runtime doesn't add much security. Your map file would be readily reversible by any moderately skilled hacker. If you want to keep the map file private, don't add it to your exe and decode the stack trace addresses into method names when the bug report is sent to you.

    Issues with Sleep(1) called in a loop

    Answer can be found in the documentation of Sleep. Sleep can only wait for multiples of system ticks. And your system appears to tick at a frequency of 15ms. Which is typical, that being the default tick frequency. There are many many discussions of this online. Here's one: https://stackoverflow.com/questions/3744032/why-are-net-timers-limited-to-15-ms-resolution

    Is a "bare-minimum" EurekaLog possible?

    Yes, I understand the behaviour, but I just don't know the use case. I guess it just be some exception handling model that I've never used. Like Mathias I tend to raise a new exception, or re-raise. But obviously breaking language feature is not desirable.
