Localization is a process by which you allow people of different cultures, languages and nationalities access your Web site. Although still a difficult process, all things considered, it is gradually becoming easier. Both the Java platform and the .NET platform have some nice features to aid localization. For instance, all strings, dates, and numbers are internally locale aware and when printed or validated will honor the localization setting. Read the rest of this entry »

Just about every book or article I’ve read about Atlas has given me a headache. They seem to have two messages in common: (1) all my server-side ASP.NET applications are now obsolete, and (2) the only way to fix them is to add really complicated JavaScript. Woe is me. Read the rest of this entry »

The .NET framework contains a number of cryptography services that allow you to incorporate security services into your .NET applications. These libraries are located under the System.Security.Cryptography namespace and provide various functions such as encryption and decryption of data, as well as other operations such as hashing and random-number generation. In this article, I will show you how to use some of the common security APIs to make your .NET applications more secure. Read the rest of this entry »

If it were the name of a variable, property, or method, it would cause a compile-time error (assuming the Read the rest of this entry »

In a recent project, my team had to produce a platform that included a set of base classes that other developers could use to develop Windows forms in Visual Studio .NET 2003. As we worked on the base classes, it became clear that our developers would be able to crank out their forms a lot faster if we could also generate stubs and skeleton code for all of the methods they needed to override in their own classes.

One time in .NET that you need to know about satellite assemblies is when you are dealing with localization. For localizing text, one doesn’t hard code text on a page, but uses a key for that text. The text equivalent for the key is retrieved from a file called a resource file. A resource file is essentially a dictionary of associations between the keys and their textual values. You will have this resource file duplicated once for each language that you support. .NET will retri Read the rest of this entry »
