The document provides an introduction to .NET including:
- The goals of the .NET framework which include improved development, deployment, and execution.
- An overview of the .NET platform and framework including the common language runtime, base class library, and support for multiple languages.
- A brief description of C# as a managed code programming language that is part of the .NET framework.
Tips and Tricks of Developing .NET ApplicationJoni
?
This document provides tips and best practices for developing .NET applications. It covers general best practices such as optimization of loops, proper object disposal, and avoiding unnecessary object instantiation. It also includes ASP.NET specific tips like disabling viewstate if not used and avoiding unnecessary round trips to the server. Windows Forms tips involve using multithreading properly and marshaling method calls to the correct thread. The document recommends using existing libraries and not reinventing functionality unnecessarily.
This document introduces HTML and its basic concepts. It covers the following topics: web standards including HTML, CSS and XML; the structure and syntax of HTML documents including tags, elements, attributes, and special characters; and some common HTML tags for text formatting, images, hyperlinks, lists, tables and more. It also discusses using color in HTML through RGB hex codes and color names.
The document discusses C# and the .NET framework. It covers:
- The goals and components of the .NET framework, including the common language runtime (CLR) and class library.
- Key concepts in .NET like value types, reference types, boxing/unboxing, and the unified type system.
- Features that enable component-oriented development in C# like properties, events, and attributes.
- Productivity features of C# like parameter arrays, ref/out parameters, and foreach loops.
The document provides an introduction to Active Server Pages (ASP) and covers several key concepts:
- ASP allows for server-side scripting using VBScript or JScript to dynamically generate web pages. Scripting code is placed between <% and %> tags.
- Basic programming constructs like variables, if/else statements, loops, and functions can be used to add logic and dynamically output content.
- Forms allow collecting user input which is submitted to an ASP processing page via the POST or GET methods.
- Server-side includes and built-in objects like Request, Response, and Session provide functionality to include pages, access submitted data, send output, and maintain state across pages.
This document provides an introduction to ASP.NET, including: how it differs from ASP by being object-oriented, compiled, and separating code from content; its goals of improving code quality, deployment, scalability and supporting different devices; benefits like multiple languages, server processing, controls, consistency and deployment; and how it enables web services and mobile controls.
This document provides an introduction to using ActiveX Data Objects (ADO) in ASP to access and process data from various database sources. It discusses ADO objects like Connection and Recordset that are used to connect to databases and retrieve data. It also covers making database connections through connection strings, executing SQL commands and stored procedures, and retrieving and updating data using a Recordset object. Examples are given for connecting to Access and SQL Server databases using both ODBC and OLE DB providers.
