This all started out because I needed to take the contents of a RichTextBox in an application I had developed and insert it into the body of an email. We're a Microsoft shop all around, so I could depend on Outlook 2007 to be the email client for all users, and I assumed (poorly) that I would be able to insert rich text into an Outlook email with little or no problem. Silly me....

Cascading Deletes in LINQ to SQL with Visual Basic

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....

Visual Basic .NET is the result of a significant rebuild of Visual Basic for the Microsoft .NET Framework. There are a number of changes that make Visual Basic .NET easier to use, more powerful than Visual Basic 6.0, and give it the kind of access to system resources that in the past required the use of languages like C++. One of the most important additions is object inheritance. In Visual Basic .NET, all managed types derive from System.Object.
An important new language feature is garbage c...

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....

With the upcoming release of Visual Basic .NET 2003, the language has received two additions: the ability to initialize loop control variables in For/For Each loops and two new bitshift operators. No changes have been made to the language that will break compatibility with the original release of Visual Basic .NET....

Control arrays were the best way to manage the controls on your Visual Basic forms, but there are no control arrays in Visual Basic .NET. Deborah Kurata describes how to use new Visual Basic .NET features to obtain control array functionality without the need for a control array....

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....

Building an audit trail into your application provides a mechanism for tracking who updated what when, and the new generics feature in Whidbey helps you build that trail.The Whidbey release of .NET will include a new Common Language Runtime (CLR) feature called generics. Generics allow you to use a variable to represent a desired data type, and thereby create very generic code (hence the name) that works with any data type.You define the data type for the generic variable at run time and the CLR...

Introducing LINQ for Visual Basic

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....

Read Reviews | Write Review |  Your Rating: 

A revised Collection class similar to the VB6 Collection is defined in the Microsoft.VisualBasic namespace. Visual Basic .NET has added several new Abstract Data Types (ADTs) to ultimately replace the Collection class. The names of the new classes were enumerated in Chapter 2, including an example of using the Stack class. The subsections that follow demonstrate ArrayList, HashTable, SortedList, and Queue. The ArrayList class is a designed replacement for an unadorned array. Although arrays in V...

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...

Commands in VB.NET come in two flavors: statements and functions. A statement is a command that stands on its own and simply does something. A function, on the other hand, returns a value for you to use in your code.This article describes how functions work and introduce you to some functions that are handy when dealing with dates....
