In this article we will discuss providing a programmable method of securing files on for your ASP.Net applications. This code could come in handy where you have an application hosted on an ISP and you do not have access to a folder outside of your Web directory structure, and you are not able to change permissions on folder in the Web. This method does not require storing your file in a binary field in your database, thus reducing cost of having to buy database storage from your ISP, and with no impact on the network traffic between the database and web servers.

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.

The author writes "One of the things that keeps coming up as a benefit of switching to ASP.NET is the ability to use code-behind to separate display code from application logic. In Visual Studio.NET, this is 'automagically' done for you. So what if you don't have VS.NET? Here's how you can implement code-behind using just a plain old text editor and the tools included in the .NET Framework... no VS.NET required!" Source codes available for download.

Have you ever needed to have an image of some text generated dynamically on the fly?

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.
