  1. This story is kinda strange. First, tampering "the exe" to get the managers password, then "every employee" had a "modded" exe. I think somebody played around with the user rights and don't want to admit. Anyway, it's better to avoid such smart A customers.... "delphi software unsafe". muha

    Make a complete DataSet event conditional??

    Nope. Wrong side of the horse. Redesign it to be able to control it from the applications.

    Round() appears to be non-deterministic

    Please pardon me for asking this, but are there ppl. using Delphi's built in Round()?

    The Case of Delphi Const String Parameters

    @Kas Ob. you don't have to be scenical, there are several methods out there with (const T; var T), and if you don't know the implementation detail you can run into it very quickly. The compiler won't give you any hints either.

    The Case of Delphi Const String Parameters

    I ran into this once function x(const input: string; var output: string): boolean; begun while we read input do alter output; end; if x(s,s) then; except that it wasn't easy to track down, it was a one time "achievement" in my life. Yet. given that, I consider every method having a const and var parameter of the same type as a time-bomb.
  6. No, but obviously you already made a nice helper https://stackoverflow.com/questions/34442102/how-can-i-get-the-number-of-elements-of-any-variable-of-type-set AD? 😉

    Unfixed bug in Sydney

    Ahm. No? You can always get out and stick with one particular release for decades.

    Unfixed bug in Sydney

    >The 3 ingredients required to expose the problems are: >1. Have an inline variable There I stopped reading. Most likely it will be fixed in the next release, but don't understand ppl. using this very new (not mature enough) feature, especially in 3rd party products. Use a decent library instead. (sorry)

    Are Valid Dates?

    Time without time zones are like numbers without units. Like the numbers on the street. (30) I always interpret them as weight limits.

    Looking for a (virtual ) pdf-printer, capable of FGL

    Did you check if Boca Systems provide a PCL driver? Or is it the opposite way? Not much support from boca. And the Text Driver they have is not a WYSIWYG.
  12. it's a 2 min copy&paste task from the link above, I can't see why would anyone reinvent the wheel just to avoid using the json library? Is it for some embedded computer?
  13. easy af, like in this article: https://www.fmxexpress.com/convert-ini-files-to-json-and-back-with-xsuperobject-in-delphi-xe6-firemonkey-on-android-and-ios/

    Example of wasteful, innefficient string manipulation

    And I guess, you are expecting something from us, we can't deliver. Yes. It's even better. In the case "very well" and "even better" are SI units.

    I can't see any technical questions regarding to your fears. All I can see is some sort of blogging about some mind-blowing nonsense and that you are not even willing to read a word about it. I don't know how could we help. Or why.

    Why are you interested by something doesn't interest you?

    Example of wasteful, innefficient string manipulation

    Sometimes, before I can make my decision in a particular matter (not programming) I do google/read/watch/test for days or for a week or once in a time even longer. If you would use the time for the same instead of this kind of nonsense topics, you would have more of it. We too.

    Images in High DPI, how?

    Ok, I thought the Per-App scaling would be ok for the icons. However other things could be broken, like grids.

    @c0d3r which windows do they have? Is there Per-App Scaling already available?

    Images in High DPI, how?

    A 4K display is also a change, but I can feel your pain. Maybe you could make it optional, to switch to a new icon set. Especially on HDPI.
  23. Attila Kovacs

    Images in High DPI, how?

    as I mentioned, the scaling is upward and the actual size is about the same, so the vector image scaled will look even better, but maybe my eyes are not working properly and you are right or whatever, please try to convience me that i'm not just dumb but I can't see shit.

    Images in High DPI, how?

    @Anders Melander That is not an svg issue, it's a general problem. I solve this by trying multiple candidates on the smallest dimension I need and choose the best one. Or many times editing it to get the best out of it. For example, wrong dimensions defined in the SVG could result a blurry small image, meanwhile by adjusting it will give a crisp image etc... Nobody told you it's easy and fun! But it has to be made only once!

    Images in High DPI, how?

    @David Heffernan I don't, but I have one master main svg-imagelist and two client svg-imagelists chained to it, all three having different dimensions. As the scaling is always upward (or none), and so is the resolution there are no regressions I encounter or I could think about. You have to be more specific about your concerns.
