The .NET platform doesn't have complex numbers built in. If you do scientific calculations such as groundwater modeling, complex numbers are essential. This article describes a full implementation of complex numbers for .NET, and how to use it with VB or C#. Complex numbers have a real and imaginary part. Math operations are performed on complex numbers using special rules to keep track of the real and imaginary parts. Fortran and C++ have complex numbers built in.... |

VB.NET library with all necessary classes for exact cover solving with dancing links. Demo project shows how to use library for solving Sudoku. Two years ago I started solving Sudoku which is still one of my favorites for spending free time. When searching internet for tasks, I found top 95 Sudokus. There were no solutions given and when solving I often figured out I made a mistake in some earlier stage of solving. To verify part solutions I needed solutions and couldn't find solver at that time... |

Microsoft Internet Explorer comes with a fairly comprehensive, although sparsely documented, Object Model. If you've used the Web Browser control in Access, you are already familiar with the capabilities of IE's Object Model. All of the functionality in IE's object model (not counting external support, like scripting support etc.) is provided by the following two dlls:
shdocvw.dll (Microsoft Internet Controls)
mshtml.tlb (Microsoft HTML Object Library)... |

Many developers will view themselves primarily as consumers of generics. However, as you get more comfortable with generics, you're likely to find yourself introducing your own generic classes and frameworks. Before you can make that leap, though, you'll need to get comfortable with all the syntactic mutations that come along with creating your own generic classes. Fortunately, you'll notice that the syntax rules for defining generic classes follow many of the same patterns you've already grown ... |

The Singleton pattern ensures that only one instance of a class is created. All objects that use an instance of that class use the same instance. This is the most common design pattern, and easy to implement, but very powerful when used properly.... |

Often when you have a number of people on a network who are logical "subscribers" to certain events, changes or other business - related happenings, you want to have a simple way to "Fire and forget" notifications to these people. VB.NET Class Library provides a shell interface to the "NET SEND" utility, which as we all know results in a popup on our machine with the message that was sent (provided we have the Messenger Service operating). Note this is the native Windows Messenger service like f... |

Dates are strange beasts that do not lend themselves well to being handled in code. I'm probably preaching to the choir with that bold statement; but, if your experience is anything like mine, you've had to include dates in your applications often, and doing any but the simplest tasks with dates has been challenging. The Date Wizard class library is intended to be a toolkit that simplifies many date related tasks.... |

The .NET Framework is Microsoft's new computing platform that simplifies the design, development, and deployment of computer applications. Developed particularly to facilitate the creation of Internet applications and distributed Internet applications, the .NET Framework features the .NET Framework Class Library (FCL), a systematic class framework to be used for the development of system tools and utilities as well as application software. This chapter assesses the significance of the .NET FCL a... |

Most of us already know about the wide array of languages the .NET Framework supports. We also know that we can code assemblies that make up projects using different languages. Something that we might not be so aware of is, coding one assembly using more than one language.... |

Although the cryptography classes of the .NET framework have been discussed at length on CodeProject and elsewhere, I can not help but think that most examples are either over simplified or just not thorough enough. And hence I have written yet another article on the topic.
Most articles show in a few lines of code how to encrypt a string into a byte array. That's just great, but what is a developer to do with just a byte array? Often that is just not useful.... |

As the core API set underpinning managed application development in .NET, the Base Class Libraries, receive several long-awaited and notable additions in the Whidbey release.The Base Class Libraries (BCL) provide a standardized set of managed APIs to accomplish all of the common and most widely executed application tasks. BCL enhancements surface in as performance-based improvements, class-oriented feature additions, and the introduction of previously missing functionality through entirely new c... |

To modify or extend UtilityBelt.vb the best way is to inherit the LearnAsp.UtilityBelt object. This has several advantages. One advantage is that since you never modified the UtilityBelt.vb you got off the website you don't need to sync your changes with ours. Plus if you like UtilityBelt but dislikue the way we implemented some of it you can replace any of our methods with your own.... |

This UTILITY BELT library is designed so that brand new programmers can use it easily. A lot of thought went into making the library easy to call without having to learn any kind of sequencing of inter-related calls. We wanted to get beginning coders started reusing code immediately when learning ASP.net, so we invented the Utility Belt library with several compelling reasons they must use it!... |

The demo project comes with an Access database (demo.mdb) that contains a table named Products. The main demo form lists all of the records from the Products table, and provides buttons for adding, changing, and deleting products. A second form is used for both the New and Change functions. Communication of data and states between the main and the second form is done primarily via PO box variables in a common module.... |

The entire source code for this article is available in the form of downloadable zip. The solution was developed using Microsoft Visual Studio 2003 Enterprise Architect with Microsoft SQL Server 2005 Developer Edition on Microsoft Windows Server 2003 Enterprise Edition. Even though I believe that the source code available with this contribution can work with Microsoft Visual Studio.NET 2002, I didn't really test it in any other environment. I request that you post in the discussion area if you... |

In one of my recent applications, I needed machine name, program files folder, and other system related variables. The System.Environment class provides handy members to do so. In this article, I will talk about the Environment class and its members and how to use them in your applications.
The Environment class defined in the System namespace allows developers to get the information about the current environment and platform. Listing 1 describes some of the Environment class properties.... |
