Microsoft is set to release an exciting upgrade to ASP later in 2000. This is a major upgrade unlike the minor changes from ASP 2.0 to 3.0. Unlike past upgrades, however, this one will not be painless. When they designed ASP+, Microsoft had to make the hard decision occasionally to break backward compatibility in the interest of improved functionality and features. Before embarking on the inevitable—and not painless—migration to ASP+, it's best to know what compatibility issues you'll have to deal with. This article covers Compatibility Issues, API changes, Semantic Changes, VB Language Changes, and more.

Since "classic" ASP's humble beginnings, ADO data access classes and methods have been re-written to form ADO.NET. This article looks at the differences (in terms of classes, methods, and calling conventions) that exist between ADO and ADO.NET. It provides several practical examples that show us how to evolve from using ADO with ASP to using ADO.NET with C# and ASP.NET.

This article examines how to can create a Web service in .NET and then utilize it from a classic ASP page on your Web server, thereby providing an API that can be utilized by both your ASP.NET Web pages and classic ASP pages.

The term "web service" has been used quite frequently lately: you hear people saying how good web services are and how they will dominate the future of software development, but what exactly are web services and how can we create them? This article shows us how to build two web services and also unravels all of the lingo surrounding web services.

Learn about the licensing requirements for ASP.NET server controls and learn about an ASP.NET control licensing implementation that can be used with versions 1.0 and 1.1 of the .NET Framework. The implementation can be extended to create custom server-side licensing schemes.

How do you operate an Analysis Services data warehouse? Learn how to configure, secure, backup, restore, and monitor the database. Learn techniques for developing and running a system that gracefully handles change in data, design, and usage.

Some ADO.NET sessions focus on the object model and .NET Framework classes and not on specific data access tasks that ADO.NET can solve. This session assumes you're somewhat familiar with the ADO.NET object model and want to see how to address the common tasks your application is likely to perform. Focus on getting connected in an ASP and Windows application, how to setup and run ad hoc queries as well as parameter-driven stored procedures, with and without returned parameters. See how to bind to DataReaders and DataSets and when it makes sense to use each. See how to fill and bind to a ListBox and a DataGrid and how to update the data, even when the query is the result of a complex join.

This article covers using the System.Drawing.Bitmap and drawBrush to draw text on a bitmap in memory. You could use this code as a base to create dynamic navigational buttons for your site.

Learn how to use the tools and options in Visual Studio .NET to increase your productivity and work efficiently in a team environment when building ASP.NET applications.

Learn about the basics of building mobile Web applications with ASP.NET Mobile Controls. See how the control model and drag and drop designer make it easy to target nearly 200 devices (cell phones, PDAs and pagers) from a single mobile Web form. Find out what the adaptive rendering and rich customization and extensibility models can do for your mobile Web applications.

In this code snippet we're going to provide will enable you to add text to an image in memory. One use for this code may be to open a file on the file system and add some text to the image, then stream the image out to the user. This could come in handy if you want to create navigational buttons for your Web site dynamically based on a request or dynamically create banners via .Net code.

This article provides one solution for replicating content to multiple share locations. This could be useful where you have a Web application hosted on a Web farm and you wish to have files uploaded via the Web, and then replicate the uploaded files to other servers in the farm.

In this article we cover using the System.Net class to make an HTTP request and return the status code. In addition, we'll cover handling the HTTP response and binding it to an XSL transformation.

Consider the perceived risks of migrations that tend to cloud the benefits of new technologies from a business perspective, making it difficult to justify technology migrations to the decision makers in an enterprise. See how these risks can be identified, planned for ahead of time and evaluated against cost, time to market, and other business factors so that the project planner can have a solid handle on the bottom line of a project. See examples from a real-world commercial application and look at each of the business and technological factors that needed to be addressed when migrating an ASP application to ASP.NET on the soon to be released Windows Server 2003.

Learn the new exciting features of ASP.NET 1.1. This session covers the changes from ASP.NET 1.0 and includes new features such as Code Access Security, IPv6 support, and support for running multiple versions of ASP.NET side-by-side.

This article explains what are "Delegates"? And what is their role in .NET framework. The author uses VB.NET code to provide working examples of "Delegates".

This guide presents a practical, scenario driven approach to designing and building secure ASP.NET applications for Windows 2000 and version 1.0 of the .NET Framework. It focuses on the key elements of authentication, authorization and secure communication within and across the tiers of distributed .NET Web applications.

This article discusses different options you as a developer have in ASP.NET to send data from one ASP.NET page to another. Since you cannot use ASP.NET Web Controls (System.Web.UI.WebControls) in such a scenario (which only allow posting back of data to the same page), this article discusses other ways like using HttpContext object.

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.

This article provides one solution for replicating content to multiple share locations using VB.Net. This could be useful where you have a Web application hosted on a Web farm and you wish to have files uploaded via the Web, and then replicate the uploaded files to other servers in the farm.
