50 Years of Pascal by Niklaus Wirth. (in Russian)

For those who are interested, this book has been translated into Russian:

"Руководство по Object Pascal", Марко Канту.

@KPB You can't install Delphi and C CE editions at the same time.

converting thousands of images to svg

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

For High DPI support you should consider SVG. 

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.

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. 🙂

My last trial license was RAD Studio XE3 Architect Trial.

@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.

I have clear.cmd file in my project folders to remove any temporary files, which contains the command:

del /f /s *.~* *.bak *.dcu *.identcache *.local *.map *.drc *.cbk *.stat *.tds

RAD Studio November 2020 Roadmap PM Commentary

Christmas is too late.

const STX=#$02;

isn't the same as

const STX='#$02';

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

packed record

> fillchar( MyData, Sizeof(TMyData) , 0 );

MyData := Default(TMyData);

Have you seen QuickJS Javascript Engine: https://bellard.org/quickjs/

The author claims almost complete ES2020 support.

Where do you store reference variables for the tables? I.e. table1, table2 etc.

Just a remark: I saw the reverse picture when my Win32 application in the Windows XP VirtualBox was running one and a half times faster than in the Windows 10 host machine...

Have you set the overflow and range checking in the project options?

Yes, it's possible. And just in case an user needs to stop the download, I added the corresponding button. Now there are 3 states: dsIdle, dsExecuted and dsStopped.

Hi, @clubreseau

@Remy Lebeau gave you everything you needed to finish the job. But OK, in the attachment to this message is a ready test application based on Remy's code, with the addition of a thread pool. Tested on Delphi CE.

Good idea with the pointer,  you do have to encode somevalues in the stringbuilder (escape special chars etc)

 

maybe with an TInterfaced (no need to free)

With Marat's proposal, you should not explicitly free the memory. Moreover, the record will be located in the stack, as opposed to the object.

There are two points. 1. It would be possible to add a helper for the string type, but then the standard helper for this type will stop working. 2. It is considered good style to have specialized string or numeric types for special uses.
