This document provides an overview of basic programming concepts and tools in Visual Studio. It discusses namespaces as containers that organize code and avoid naming conflicts. It also describes several Visual Studio tools like the Solution Explorer for managing solution files, Properties Editor for editing object properties, and Toolbox for adding controls to forms. Finally, it provides steps for creating a Windows Form application, adding controls, and debugging the application.
ASP.NET Session 4
- 2. Objective • NameSpace • Several Tools. • Solution Explorer, Property Window & Toolbox • Windows Form
- 3. Namespace • A Namespace in Microsoft .NET is like containers of objects. • Main goal of using namespace in .NET is for creating a hierarchical organization of program. • In this case a developer does not need to worry about the naming conflicts of classes, functions, variables etc., inside a project. • The advantage is that every namespace can contain any number of classes, functions, variables and also namespaces etc., whose names are unique only inside the namespace.
- 4. Namespace(Example) // Namespace Declaration using System; // User created Namespace namespace hello { // Program start class class space { // Main begins program execution. public static void Main() { // Write to console Console.WriteLine("This is the example of creating own Namespace."); } } }
- 5. Other Tools There are numerous tools available in Visual studio IDE. We will use the following.. • Properties Editor • Solution Explorer • Toolbox
- 6. Properties Editor • The Properties Editor tool is used to edit properties in a GUI pane inside Visual Studio. • It lists all available properties (both read-only and those which can be set) for all objects including forms, web pages and other items.
- 8. Solution Explorer • In Visual Studio , a solution is a set of code files and other resources that are used to build an application. The files in a solution are arranged hierarchically, which might or might not reflect the organization in the file system. • The Solution Explorer is used to manage and browse the files in a solution.
- 10. Toolbox • Visual Studio provides a Toolbox which can be used to add numerous controls to a Windows Form or a Web Form. • On the Design pane we can add those controls by selecting and dragging the desired control.
- 12. Creating a Windows Form Application • To create a Windows Form Application we have to click on File-New-Project or simply Ctrl+Shift+N from the keyboard. • The ‘New Project’ window will appear. • On the ‘New Project’ window we have to select the ‘Windows Form Application’ and click ‘Ok’.
- 14. • A new design window will open. It will be look like this…
- 16. • On the design window we can add any Controls from the toolbox. • Here I have taken the Button and the TextBox Control.
- 18. • After that we have to write code for the Windows Form application.
- 20. Debugging the Windows Form Application
- 21. Summery • Several Tools. • Namespace. • Hands on knowledge on Visual Studio IDE. • Creating Windows Form Application.
