- 5. Sponsored by What is Delphi and how it works ? ● Delphi is an IDE : integrated development environment. ● Delphi use a language to code : Object Pascal. ● Delphi give us a lot of libraries and coding interfaces. ● And finally, Delphi has visual and nonvisual components for designing user interfaces.
- 6. Sponsored by What is Delphi and how it works ? ● Since Delphi 1 we can create programs without coding. ● Current programs can run on Windows, Mac, Linux, iOS and Android. ● Let me show you how to do with Delphi 11 Alexandria.
- 7. Sponsored by What is Delphi and how it works ? ● In Delphi, a program is a project. ● You can create Windows only programs with VCL projects. ● You can create multiplatform programs with FireMonkey projects.
- 8. Sponsored by How to draw user interface ? ● Create a new project (VCL or multiplatform). ● Delphi will add a form, the canvas where you’ll draw the user interface. ● Simply drag & drop your components from the components list and it works…
- 9. Sponsored by Using databases (client/server, local or in memory) ● In the past we had the Borland Database Engine (BDE) but it’s deprecated and was replaced by dbExpress, dbGo and now FireDAC. ● With FireDAC you can manage databases directly from the IDE and of course in your projects. ● Add a connection to your database, add queries or tables and link them to visual component for displaying or editing your data.
- 10. Sponsored by How to add screens in a program ? ● In no code mode, you’ll have to use tab controls to simulate screens and standard actions from action lists to go from one screen to another. ● Only one form is needed, but beware : it’s better to know some Pascal commands to show / hide / activate other forms.
- 11. Sponsored by How to access web API ? ● Delphi has a TWebBrowser to display HTML pages. Use it to show local documents or web sites. ● You can also use TRESTClient, TRESTRequest and other TRESTxxx nonvisual components to access an http/s server and get its answer as a table in memory. REST Debugger is a free tool to use to configure those components. It’s available from Embarcadero website or in Tools menu option of Delphi.
- 12. Sponsored by How to access web API ? ● Please look at David Cornelius presentation if you want a demo. https://delphicon.embarcadero.com/talks/delphi-does-low- code-cross-platform-rest-client-in-30-minutes/

- 14. Sponsored by You want more ? ● Using Delphi for creating simple database apps is easy and you don’t need to know how to code. ● Use it for your personal databases, for sample projects or prototypes. ● You also can use Delphi without coding during Startup Week- ends or hackathons if you need a program or mobile app to explain a concept or win a challenge.
