Read Reviews | Write Review |  Your Rating: 

This article will discuss alternative methods for performing cascading deletes using LINQ to SQL. Cascading delete refers to the action of removing records associated by a foreign key relationship to a record that is the target of a deletion action. LINQ to SQL does not specifically handle cascading deletes and it is up to the developer to determine whether or not that action is desired. It is also up to the developer to determine how to go about accomplishing the cascading delete....

This month is a continuation of the Basic Instincts column that appeared in the May 2001 issue of MSDN® Magazine. In May's column, I discussed how the Visual Basic® language has been enhanced to include many new conveniences. I explained how the language designers have improved the syntax of Visual Basic to promote higher levels of type safety and consistency. I also showed new syntax for dealing with familiar concepts such as properties and arrays....

Arrays provide convenient ways to work with groups of controls that share common functionality. Groups of controls might be used to display related data, or provide related behavior when clicked, for example. Although Visual Basic® .NET and Visual C#® have no inherent support for creating control arrays, you can duplicate all of the functionality of control arrays programmatically. This article will walk you through the creation of a simple component that duplicates control array functionality....

C# 3.0 incorporates LINQ (Language INtegrated Query), a cool technology that adds dynamic queries to all kinds of objects in a familiar SQL-like style. LINQ code looks like embedded SQL statements, which I actually don't care for because SQL has never looked pretty to me. I also do not believe that LINQ adds clarity to code. It looks terse and somewhat ambiguous. In a nutshell, LINQ is a sexy technology (as they are fond of saying in Redmond), but it is not pretty....

In the February 2001 issue of MSDN® Magazine, I wrote an article discussing the new Microsoft .NET Framework and the role that Visual Basic .NET plays in building software for this platform. In that article I discussed the motivations that led Microsoft to reinvent their development platform and the underlying reasons why the Visual Basic® language required such a drastic overhaul. This month I'd like to build on that article, so I'll assume you've read it (see "Visual Basic .NET: New Programmin...

This is the first in a series of articles that describe the fundamental changes in Microsoft Visual Basic® and how to do today with Visual Basic .NET what you used to do with earlier versions of Visual Basic. The original versions of Visual Basic provided control arrays for managing the controls on your forms. Control arrays had several benefits. They allowed you to share event procedures for a set of controls. For example, one GotFocus event procedure could handle the focus event for all of the...
