Does anyone have good routines for parsing ISO8601 date(time) strings
Der schöne Günther replied to Tommi Prami's topic in RTL and Delphi Object Pascal
That is indeed annoying, but we haven't stumbled upon a "real" bug. We are using String/DateTime conversion for Iso8601 from the System.DateUtils all the time. -
Disabled floating point exceptions are problematic for DLLs
Der schöne Günther replied to A.M. Hoornweg's topic in Delphi IDE and APIs
Strictly speaking, this is not exclusively related to Delphi 12, your DLLs would have suffered the same, if they were called from another non-Delphi application. I believe that if your code relies on a certain FPU behaviour, it should either fail-fast by aborting if the FPU is not set correctly, or temporarily alter it, and then restore it to the previous state via try..finally. In any case, that would be your DLL would have to be changed. -
Good delphi learning sites for new team member

That's a super interesting concept, but the content appears to be around 15 years of age. -
Delphi - Direct2D - Paintbox drawing is flickering
Der schöne Günther replied to Achille PACE's topic in VCL
I am not familiar with Direct2D, but confused nonetheless - Wouldn't you need a HWND to paint into? And a TPaintBox is not a window control, it's a simple TGraphicControl descendant - Meaning you may probably paint onto your form or into that very panel, but I fail to see how a Paintbox is even remotely helpful. Thanks for updating the code snippet. Didn't know you can also create a TDirect2DCanvas pointing to a Canvas, instead of a HWND. -
State of an uninitialised variables..
Der schöne Günther replied to Ian Branch's topic in Tips / Blogs / Tutorials / Videos
Yes, but we're just mere humans, and we don't even have a compiler that will help us by generating a warning. Even the gods from Embarcaddero occasionally trip over this, here is an example straight from the RTL itself: https://quality.embarcadero.com/browse/RSP-18300 -

I wouldn't really call those features - Rather oddities, quirks or flat-out defects 😬 You can hardly blame yourself for not expecting something like that. -
Real time desktop colors change like filters
Der schöne Günther replied to William23668's topic in Windows API
This surely isn't trivial. I once was about to make small tool for inverting the colors of windows that did not support a "dark theme" but I never really got started with it. It seems that you can use the (now deprecated) Magnification API to (selectively) transform colors or run filters on the whole screen (or just selected parts of it like rectangle areas or selected HWNDs): Magnification API overview (Applying Color Effects)| Microsoft Learn There is also its successor, the Desktop Duplication API - Win32 apps | Microsoft Learn which I had only used for grabbing screen data, not manipulating it. So I cannot say if it's a feasible solution for manipulating the colors. -
State of an uninitialised variables..
Der schöne Günther replied to Ian Branch's topic in Tips / Blogs / Tutorials / Videos
Although he explicitly said local variable, it could probably have been something like this: program Project1; function getText(const txt: String): String; begin // Incorrectly assumes "Result" got // initialized to an empty string Result := Result + txt; end; begin var text: String; text := getText('This should not be visible'); text := getText('Hello'); // Outputs "This should not be visibleHello" WriteLn(text); end. -
But what's new? And why is the .iso just 730 Megabytes? 🤔

DelphiLint v1.0.0 released!
Der schöne Günther replied to Elliot Hillary's topic in Delphi Third-Party
I have a stupid question about Does that mean it runs entirely self-dependent, and I do not need a license for SonarQube? -
My point is that it was not necessary to add this in the first place. Without knowing better, they got talked into changing a working part of the RTL, adding new bugs and breaking existing code.

Stuff like that makes me lose all hope. They still don't appear to have at least a minimal test coverage for the standard library. It was already reported and is allegedly fixed in "RAD Studio 12 Athens Patch 1" See: [RSP-43463] JSON serialization error with scientific double notation - Embarcadero Technologies -- Also, I have absolutely no clue why they decided to add this in the first place. The JSON specifications are crystal clear: https://ecma-international.org/publications-and-standards/standards/ecma-404/ See also: RFC 8259 - The JavaScript Object Notation (JSON) Data Interchange Format (ietf.org)

It sounds like you are trying to add an exception logging mechanism to your application. Would you like some help? All jokes aside, if that's the case, then you should really investigate proper stack tracing and exception logging mechanisms. In case (for whatever reason), you really just like to add the current line number into a string, then have a look at: https://stackoverflow.com/q/7214213

Well, that de-escalated quickly.

Delphi and "Use only memory safe languages"
Der schöne Günther replied to Die Holländer's topic in General Help
For those who still can't get enough, here is a very recent article from none other than Herb Sutter, of course with emphasis on C++ C++ safety, in context – Sutter’s Mill (herbsutter.com)
