    Study Notes

    Lecture Overview

    • This document is a course outline for a computer programming course.
    • The course is titled "Modern Computer Languages (part 1)"
    • The instructor is Dr. Hamdi Suleiman Daraz.
    • The course is offered at the Department of Educational Technology, Faculty of Education, Damietta University.

    VB.NET Overview

    • VB.NET is a programming language.
    • Programming involves providing step-by-step instructions for a computer to perform tasks.
    • A program is a set of instructions that tells a computer what to do, like performing calculations.
    • A computer cannot work without specific instructions (or a program).
    • Programs are created using programming languages.
    • Visual Basic, C#, Delphi, Java are examples of programming languages.
    • Every language uses commands in English.
    • A program is also called a project, containing multiple files and objects in .NET framework.
    • The IDE (Integrated Development Environment) is the set of tools used to design programs, and in .NET versions, one IDE can support multiple languages.

    Introduction to Programming and VB.NET

    • Computers are tools for completing tasks efficiently.

    • A computer requires precise instructions to solve problems, a process called programming.

    • A program is like a set of directions for the computer to carry out a specific task.

    • Computers don't think, they just execute the given instructions in sequence.

    • Programming aids in repetitive tasks by reducing the need to manually repeat steps.

    • Calculating a student's grade exemplifies the need for programming

    Programming Concepts Explained in VB.NET.

    • Program: A set of instructions directing the computer to perform a specific action or operation.

    • Programming language: A language used to communicate instructions to the computer.

    • Programmer/Developer: Individual who creates programs by writing instructions/commands for the computer.

    • IDE (Integrated Development Environment): A software tool containing various tools for program creation.

    Types of Programming Languages

    • Programming languages are used for instructing computers to execute tasks.

    • Microsoft .NET environment introduces a framework with various supported languages, making it possible to use more than one language within the same program.

    • .NET languages include Visual Basic .NET, Visual C++ .NET, Visual C# (C Sharp), ASP .NET, and Jscript .NET .

    .NET Environment

    • .NET (Framework): Programs within this environment are independent of the operating system and are compatible with Windows versions.

    • .NET languages have both an interpreter and a compiler, allowing errors to be detected and corrected during the program's design and ensuring compatibility across different machines.

    • Intermediate Language (IL): A standard language converts codes from various .NET languages into a common language to run on any computer.

    • Common Language Runtime (CLR): A program execution environment translates IL codes into machine language executables.

    • Object Oriented Programming (OOP): A type of programming that structures software code around 'objects' to make complex software more manageable.

    Visual Studio.NET IDE Components

    • IDE (Integrated Development Environment): The set of tools used to create programs.

    • Visual Studio (Microsoft): Different versions exist (Professional, Team, Express).

    • Visual Studio.NET Express: A free version targeting specific language support only.

    • New project: Options for creating applications with different types of Windows interfaces.

    • Opening an existing project or creating a new one.

    Program Elements

    • Form: The container within the program that displays controls, similar to Windows application windows.
    • Controls (Tools): Pre-built elements (e.g., buttons, text boxes) facilitating program design.

    Windows Application Design with VB.NET

    • Development Tools and Techniques:

    • Windows Forms Applications: Applications designed to run within the Windows operating system.

    • Adding tools in program design: Dragging and dropping tools from the Toolbox.

    • Selecting Elements: Selecting multiple program elements (e.g., forms or individual controls).

    • Modifying tools: Modifying controls' size and location.

    • Deleting elements: Removing controls from a running program.

    Properties and Their Impact on Program Design

    • Properties: Settings controlling an object's appearance and actions.

    • Common Properties:

    • Text: Specifies the display text of an object.

    • ForeColor: Defines the text's color.

    • BackColor: Sets the background color of the object.

    • BorderStyle: Determines the border style (e.g., none, single, 3D).

    • Visible: Controls the object's visibility (on or off).

    • Enabled: Controll the object's interaction (enabled/disabled state).

    • Name: Gives each object a unique name for reference in program commands.

    Additional aspects

    • Program design details, including program structure, interface design, control placement, and property adjustments.

    • Example scenarios of program interaction.

    • Code-based modification of properties while the program is running, including the use of commands like TextBox1.Text = "My Computer".
