Getting Started with Delphi 10 ​

After installing Delphi 10, you’ll find an advanced but easy-to-use interface:

• Form Designer: Visual drag-and-drop UI builder
• Object Inspector: Modify component properties instantly
• Code Editor: Modern editor with code completion
• Tool Palette: Hundreds of ready-made components
• Multi-Device Designer: Build one UI, deploy everywhere
• LiveBindings: Connect UI elements to data without code

This makes Delphi 10 one of the most efficient IDEs for building professional applications.

Learn the Fundamentals of Object Pascal ​

Delphi 10 uses Object Pascal, a clean, readable, and structured language perfect for beginners.

Variables Example:​

var
  username: string;
  level: Integer;
begin
  username := 'Student';
  level := 1;
end;

Condition Example:​

if level > 1 then
  ShowMessage('Welcome back!')
else
  ShowMessage('Let’s begin your Delphi journey!');

Loop Example:​

for i := 1 to 5 do
begin
  ShowMessage('Lesson: ' + IntToStr(i));
end;

Object Pascal teaches great foundations that easily transfer to C#, Java, and Python.

Object-Oriented Programming in Delphi 10 ​

OOP (Object-Oriented Programming) is a core part of modern software development, and Delphi makes it extremely easy to understand.

Simple Class Example:​

type
  TCar = class
    Brand: string;
    Speed: Integer;
    procedure Start;
  end;

procedure TCar.Start;
begin
  ShowMessage(Brand + ' is starting at speed ' + IntToStr(Speed));
end;

You’ll learn:

• Classes & objects
• Inheritance
• Polymorphism
• Encapsulation
• Constructors & destructors

All taught step-by-step in the Delphi 10 course.

Building Desktop Applications with Delphi 10 ​

The real power of Delphi comes from its ability to create full-featured desktop applications quickly.
You can build:

• System utilities
• Business applications
• Admin dashboards
• Database tools
• Network apps
• Cybersecurity utilities
• Cross-platform apps

Example: Updating a Label​

procedure TForm1.Button1Click(Sender: TObject);
begin
  Label1.Text := 'Welcome to Delphi 10!';
end;

With modern FireMonkey components (FMX), you can design stunning UIs with animations, effects, and responsive layouts.

---

Working with Databases in Delphi 10 ​

Database development is one of Delphi’s strongest features. You’ll learn how to connect to:

• MySQL
• SQLite
• MSSQL
• PostgreSQL
• FireDAC
• REST data sources

Basic Query Example:​

FDQuery1.SQL.Text := 'SELECT * FROM users';
FDQuery1.Open;

Using LiveBindings, you can link UI elements directly to database fields without writing any data-handling code.

---

Networking and API Integration ​

Delphi 10 makes it extremely easy to build applications that interact with the internet.
You’ll learn how to:

• Consume REST APIs
• Send HTTP requests
• Handle JSON data
• Build network scanners
• Create automation tools

Example: REST Request​

RESTClient1.BaseURL := 'https://api.example.com';
RESTRequest1.Execute;
ShowMessage(RESTResponse1.Content);

This is very useful for cybersecurity learners and developers building modern apps.

---

Cross-Platform Development with Delphi 10 ​

One of the most exciting features is the ability to build apps for multiple platforms using the same codebase.
Delphi 10 supports:

• Windows
• macOS
• Linux
• Android
• iOS

With the Multi-Device Designer, you build the UI once and deploy it anywhere - saving huge amounts of development time.
