This tutorial covers working with application state and application-wide events within your ASP.NET application. In normal desktop applications, the notion of a global meeting place for various parts of an application is well-understood.
Work with If-Modified-Since and Last-Modified in ASP.Net. ASP.NET / Functions
Short support vb.Net functions to convert date from/to http string date and sample code to send static files with 200 OK + Last-Modified http header and 304 Not Modified when If-Modified-Since request header is present.
Web Application Basics ASP.NET / Getting Started
This tutorial covers the fundamentals of building a Web-based application. Unlike the development of most desktop applications, in which most of the parts are available locally (as components on the user's hard disk drive), developing a Web application requires getting software parts to work over a widely distributed network using a disconnected protocol. The technologies underlying ASP.NET have been around for a long time. Of course ASP.NET makes use of this technology underneath, while making it very approachable at the same time.
Session State ASP.NET / Cookies and Sessions
This tutorial covers managing session state within your ASP.NET application. Programming Web applications requires you to be very mindful of how the state of your application is distributed at any moment. One of the most important types of state in a Web application is session state - the state associated with a single particular session. Because Web applications are distributed by nature, keeping track of any single client has to be done deliberately.
Diagnostics and Debugging ASP.NET / Debugging and Error Handling
This tutorial covers the support provided by ASP.NET for figuring out what's wrong with your ASP.NET application. As you can imagine, debuging Web applications introduces a whole new set of challenges. This tutorial shows you how to watch your application as it runs and trace the state of any particular request.
Introductoin to ASP ASP.NET / Getting Started
This tutorial will help you figure out how to write Web applications using Microsoft's most current version of its HTTP request processing framework - ASP.NET 2.0.
Migration from J2EE to .NET ASP.NET / Migrating to ASP.NET

Navision Database access via C/ODBC WebService/ASP.NET Application ASP.NET / .NET and Databases
The topic of this article is Navision Attain database access through Webservice, connected to Navision via C/ODBC based Linked Server – the mechanism available in MS SQL Server 2000 and transfer the results to ASP.NET application. Our goal will be ASPX page accessing Navision Customers.
Application Data Caching ASP.NET / Web Applications
This tutorial covers ASP.NET's built-in data caching features. Caching is a long-standing means of improving the performance of any software system. The idea is to place frequently used data in quickly accessed media. Even though access times for mass storage continue to improve, accessing data from a standard hard disk is much slower than accessing it in memory. By taking often-used data and making it available quickly, you can improve the performance of your application dramatically.
ASP.NET Application Fundamentals ASP.NET / Getting Started
This tutorial covers the fundamentals involved in building an ASP.NET application. From a syntactical point of view, writing .NET code is similar to writing the classic ASP code that you may have seen during the late dot-com era. Many of the key symbols remain the same, and even some of the syntax survives. However, the entire underlying execution model changed dramatically between classic ASP and ASP.NET. Whereas executing classic ASP pages was primarily an exercise in rendering HTML, interpreting script code, and calling Component Object Model code, ASP.NET introduces an entirely new object-oriented execution model.
Custom Handlers ASP.NET / General Development
After completing this tutorial, you will be able to:
* Recognize the role of custom handlers in ASP.NET
* Write custom binary handlers
* Write just-in-time compiled custom handlers
* Let IIS and ASP.NET know about your custom handler
This tutorial covers writing custom HTTP handlers.
How to use GetDirectories ASP.NET / File Operations
While working with file system, sometimes we must list all directories in a folder. This sample shows us how to list all directories in a folder. Source code written in Visual Basic.NET can easily modify to work in an application.
