Now listed 11th in the lsit. Is this a good news for Delphier? https://www.tiobe.com/tiobe-index/

I am somewhat unclear about Delphi class constructor. Say, for the following code: TMyFunkyObject = class strict private class constructor Create; public class procedure FoBar; end; I am calling TMyFunkyObject.FoBar from the initialization section of another unit. Is it guaranteed that the class constructor will be (implicitly) called before TMyFunkyObject.FoBar? Or the sequence is in-deterministic?

My RAD Studio 10.4.2 works fine with opened project, but it ALWAYS crash upon exit (i.e., after I click the close button). however, if I don't open any project, just open the IDE then close it, no crash. This doesn't impact my programming work, but quite annoying. From Windows Event Viewer, I find the following info - I suspect the crash is related to some third-party component or some IDE expert. Any one can shed some lights?

thanks all - I ended up using Delphi's Indy 10.5 document. It works for me.

"RTC SDK was originally developed by Danijel Tkalčec in 2004, and acquired by Teppi Technology in 2018 . Now, as of May 20th 2022, we announce that ReatlThinClient SDK (a.k.a. RTC SDK) is open source." https://rtc.teppi.net/ https://github.com/teppicom/RealThinClient-SDK

For the "few other FMX grids available" - which one is the best (or better) in terms of performance ? I am looking at woll2woll FirePower X2, TeeGrid for FMX, TMS, and what else?

Any good one (open source or commercial) to recommend? Something that resembles Dephi's object inspector

Thank you for the link. On one hand, string is listed as a reserved work, on the other hand, it also says "System.String" is an alias for "UnicodeString"..........

Really, so it is a reserved word? I had thought it is a Class type, hence it should be "String"

This has been pestering me for a while For the string type, should be it "String", or "string", I saw the Delphi source code mixes the uses. Some third-party code uses "String", while some uses "string".

Delphi RAD Studio 11. Is there a way to increase the Code Editor's line spacing? I use JetBrains Mono fonts, and the lines appear too "squeezing", and it seems the line spacing is too small. Any advice?

Any third-party code formatter that can correctly format the inline var?

@Christophe E. What happened to TECMap? Also - Can TECNativeMap extract OSM data, something like this data extract service at bbbike.org: https://extract.bbbike.org/?

I would like to use FMX 2D drawing to plot an engineering diagram (with user interactions) - I need advice on where to start. Any good FMX 2D drawing demo, book, or tutorial? Thank you.

@angusi I am very interested in Image32 - forgive my dumb question - is it suitable to be used for developing CAD-like application, or interactive 2D graphics (that is based on user mouse dragging etc)? Thank you

@sakura Thank you for the heads up. Appreciated.

Yes. @Stefan Glienke With current prototype, View, ViewModel, and Model have to run within in the same thread - otherwise, the global ObservableStack would be messed up. Is my understanding right? Also currently, the DependencyList field is not of much use, thought it might be used to trace the origin of the Notify call? Any future plan for KnockOff that might be shared here? It is very refreshing code, and I learned a lot from it!

Is KnockOff thread-safe? I saw it uses a global ObservableStack without thread-protection?

{$M+} ReadOnlyObservable<T> = reference to function: T; Observable<T> = interface(ReadOnlyObservable<T>) {$REGION 'Property Accessors'} procedure Invoke(const value: T); overload; {$ENDREGION} procedure Subscribe(const action: TAction<T>; trigger: TNotifyTrigger = AfterChange); end; The above is taken from @Stefan Glienke's Knockoff project https://bitbucket.org/sglienke/knockoff/src/master/Knockoff.Observable.pas Can someone give me some heads up - is this some type of advanced usage of Delphi? can "reference to functio: T" be used as the base interface?

I know I can use TryStrToFloat, but is there any other (better, and faster) way of checking if a string can be converted to number?

For System.SysUtils.TStringHelper, I have to need to add some additional methods - is it possible to extend or "inherit" an existing class/record helper to add user-specified methods?

No need for the range check. Just whether is is a number string.

@Anders Melander Thank you for the inputs. I need a fast way to just find out if a string is "convertible" to number, I don't need to see the actual number converted. I can use TryStrToFloat, then ignore the converted number, while just looking at the returned Boolean result. The reason I need this to be as fast as possible, is - I am processing a large text file, and need to generate some statistics on how much can be converted to numbers. I don't need to actually convert numbers, just need to know the percentage of the file that can be converted to numbers (integer, or floating point). Any advice?

I have a data module that includes HTTPRIO - is there any potential issue to create an instance of that data module during its parent Unit initialization, and destroy the instance during its parent Unit finalization?
