On October 22nd, 2019, there will be another edition of Embarcadero Conference. It’s the biggest Delphi event of the world, and happens in São Paulo, Brazil. There are hundreds of attendants.
In this edition, just like last year, there will be seven simultaneous sessions, all happening in the same auditorium. You choose which session to listen by selecting the audio channel in your headphones. The full session list is available in the site of the event.
On October 10, Softacom is holding a webinar on “Databases inside RAD Studio & Delphi ecosystem. Migration process (legacy to up-to-date, to another RDBMS), data layer architecture (ORM), data access architecture (REST API)”.
Inline variables declaration is a feature introduced in Delphi Rio 10.3. What is it?
In short, it is the possibility to declare a variable in any line of your code. That is, you can declare a variable this way, within the begin..end block:
procedure Test;
begin
var I: Integer;
I := 22;
ShowMessage (I.ToString);
end;
A lot of people already understood how this feature works, but did not understand why it is interesting. In this article, I will show you this new feature with a focus on the advantages it brings.
Embarcadero has just released a new Delphi Rio version (which means also Rad Studio and C++ Builder): version 10.3.2. It’s a minor update – meaning product codename is still “Rio”, and it’s binary (DCU) compatible with previous 10.3.1 version.
Why then, an article about a minor update? Usually minor updates contain just bug fixes and small improvements, however it’s not the case of this one. I will mention here two improvements that I personally found significant. It’s also worth mentioning that Embarcadero has recently published the updated Rad Studio roadmap – May 2019 which lists the probable new improvements in upcoming major versions. Now to the improvements in this release:
A memory leak happens when your application allocates a space in memory and never frees it again.
In a Delphi application, memory spaces are allocated and released all the time. This is often done automatically by the compiler or by the RTL – for example, when allocating variables of primitive types, parameters that are passed to functions, etc. – and we usually do not have to worry about it.
