Delphi 10 VCL Essentials training – 25-27 maart 2019

De driedaagse Delphi 10 VCL Essentials training start binnenkort, op maandag 25 maart 2019 op de mooie locatie van het Jachthuis Beukenrode in Doorn.

De training is bedoeld voor developers met enige ervaring in programmeren. Maar ook ervaren ontwikkelaars waarderen hem, niet alleen door de overview van alles wat je met Delphi en de VCL kunt, maar ook door de deep-dive in details als de event-loop en de interne werking van de VCL (visual component library) en RTL (run-time library). In de driedaagse training leer je je Windows applicaties maken met Delphi, gebruik maken van een database via FireDAC. Verder in-memory en local datasets, debugging, de RTL, Windows-10 styling en zelfs wat generics.

Inschrijven en details van de agenda vindt je hier:

De training gaat zeker door, dus voor de reeds ingeschreven deelnemers, tot binnenkort!

Delphi 10.3 Rio

Delphi 10.3 Rio has been released today!

The most awaited new feature is of course support for Android 8 and 9. As you may recall Google made changes to its requirements for new apps in the app store. These requirements are now all met. Please remember to also use the new PermissionsService.RequestPermissions to request permissions for the app at runtime.

If you’re into nitty gritty details, the internal coding for parameters of methods has changed, allowing better compatibility between C++ and Delphi. What it boils down to is that for 64-bit code more parameters (between 5 an up to 8 byte in size) are now passed to functions using CPU registers, where they would previously be passed as pointers to the actual data. This speeds some code up quite a bit.

There are also some changes in the way that JSON is serialized. If you are using REST webservices with clients you may need to update both to Rio at the same time, to achieve interoperability. This mainly affects JSON serialization that internally uses RTTI. Its more efficient, but may break some existing code.
