In this article we will take a quick look at two methods for creating SHA1 passwords for use on the web using .NET. It is dangerous to store passwords anywhere in plain text!! SHA1 gives a quick and easy way to encode a password into a non-human readable form. This means it is safer to store in a database, and should the database be viewed by anyone who shouldn't know the passwords, it will be much more difficult for them to work out what a user's password is.

The author writes "With ASP.NET you can configure the 'ASP.NET engine' to automatically restart itself when certain criteria are met. For example, if the Web server has 100 requests queued up, you may wish to have the Web server restarted, assuming that some script or DLL is hanging the Web server. Additionally, you can set requirements on restarting the Web server on the memory usage, the total number of requests, or by the total time the Web server's run. This proactive approach was implemented by the ASP.NET team in order to increase the overall uptime of a Web site running ASP.NET: if the memory suddenly shoots through the roof, the Web server can be restarted, reigning in the memory usage and starting anew. The information regarding the life cycle of the current (and past) ASP.NET processes can be examined through the use of the ProcessModelInfo class." This article examines how to retrieve and present such information.

This tutorial covers one of ASP.NET's most useful features: databinding. A number of controls within ASP.NET have the capability to understand the form and content of a collection and to render the correct tags to represent such user elements as list boxes, radio button lists, and combo boxes. Here we'll examine how these controls work and how to use them on a Web page.

If you read the internet and all of the websites dedicated to Asp.Net you will inevitably read about the wonders of the DataGrid, DataList, and Repeater controls. While each of these has its place, if you are only displaying data there is a much faster and more efficient means to do so.

The basics of setting up a .net web application. When I first moved from classic asp to asp.net it took me a while to get to grips with the structure of a .net web app and the event driven methods of an asp.net web page. Hopefully this tutorial will give you an idea of how to get started.
