    is the third argument optional?

    upcoming language enhancements?

    I don't expect much from the new version, but a properly implemented iif statement would improve my code here and now.

    Developer Express gave up on FMX

    Not only. How about CrossVCL? They support Linux and OSX, and plan to support Android and iOS in 2021.

  5. I was able to install the 10.3 Community Edition on Windows XP, but it refused to work.
  6. If a single-exe project is some command line utility, which is called very often, the size matters. I'd prefer if RTTI will be disabled by default, and it could be enabled for types where it really needed.
  7. I would like to have a compiler option to disable modern RTTI throughout the application, including the linked standard library. Glad to hear that you managed to disable this information in your project.

    Can Delphi randomize string 'Delphi'?

    According to the probability theory, there is a 1/19 770 609 664 chance that on the next try you will get the desired 6-letter word. So the fact that after 400 billion attempts it has not been received looks suspicious, but not impossible. (19 770 609 664 = 52*52*52*52*52*52). By the way, here are the probabilities of finding a word with fewer characters: 1-letter word: 1/52, 2-letter word: 1/2 704, 3-letter word: 1/140 608, 4-letter word: 1/7 311 616, 5-letter word: 1/380 204 032, 6-letter word: 1/19 770 609 664.

    Delphi 10.4.2 first impressions

    @emailx45 Yes, I can reproduce in VirtualBox 6.1 with Windows 10 and Delphi 10.4.2 installed. Error: Invalid Class Typecast. Details: Though I never used this view in modern IDEs. Palette Tool window is more convenient on modern wide displays.

    Images in High DPI, how?

    I believe some type of neural network may be used for this purpose.

    Images in High DPI, how?

    For High DPI support you should consider SVG.

    How to extend CE licence?

    I confirm that the problem has been resolved. I got a new key and another 367 days on CE license, though still 10.3.3, not 10.4.

    How to extend CE licence?

    Last time the license for Delphi 10.3 CE expired, they did not renew it, but offered a new license for Delphi 10.3.3 Rio CE. Let's see what they will do this time. Hopefully, they will offer a new 10.4.x license as a Christmas present. 🙂

    How to extend CE licence?

    @Oberon82 I just tried to renew my CE license, and got the same answer.

    I don't get this: {$B-} // avoid multiple conditional jumps by not using short eval Actually $B- disables the complete Boolean evaluation. It's a default setting, and it gets a best result in this case.

    strange problem with psftp lib

    So instead of "DLL not found" you got "External Exception". This is about how important it is to name exceptions correctly and clearly.
