.NET Remoting - The Interface Approach

.NET Remoting provides a powerful and high performance way of working with remote objects. Architecturally, .NET Remote objects are a perfect fit for accessing resources across the network without the overhead posed by SOAP based WebServices. .NET Remoting is easier to use than Java's RMI, but definately more difficult than creating a WebService. In this article, we will create a remote object that will return rows from a database table. For the sake of simplicity i have used the NorthWind database that is packed with the installation of the Microsoft SQL Server.

In this article, we will create a remote object, and access this object using an interface. This method is important when creating a physical separation between business tier and consumer code. In traditional Remoting approaches, to access a remote object, you need a copy of that object on the client machine. With this approach, the metadata is split into a separate library that can be copied to the client machine.

An Overview Of Link Label In C#

BookStock v2- Samples to Show Simple OleDb.NET Connectivity

The LinkLabel control exhibits links to other objects, such as files or Web pages. Class LinkLabel is derived from class Label and therefore inherits all of class Label’s functionality. A LinkLabel looks as underlined text. When the mouse moves above the link, the pointer modify to a hand. This is alike to the behavior of a hyperlink in a Web page. The link can change color to indicate whether the link is new, visited or active.

This is part two of series of articles intended to provide practical background information on design approaches for the .NET platform as well as providing clear explanations of the .NET features it introduces. In the last article in this series, it was described how to create a Web service that consumes another Web service that does not provide its result set in a .NET DataSet, by using the WSDL (Web service description language) which the consumed Web service provides, it is described how to build from th

Christian's Code Project Screensaver

CodeDOM：Strong Type Collection Maker

Well, here it is. I'm sorry that the article is non-existant, it is very late, and I need to go to bed, but I couldn't wait to post the fruit of my labours. I will write a full article in support of my screen saver hopefully tomorrow, but I don't have access to any web space, so I'm going to use Chris's to show you all what I have done so far. The screensaver is written in C#, it simply creates a form that takes up the full screen, and it can only be turned off my pressing a key. This is because when Chris has his XML feed going, I will scroll the latest links from CP in semi transparent text, and moving the mouse will generate a cursor, and clicking on an item will stop the screen saver and launch the URL.

Developing A C# Vector Drawing Application - Part 1

It's a tools to help you create the strong type collection class.

C#Today

Computer drawing applications are one of the most popular applications. Examples of such applications are Corel Draw and FreeHand - Windows users even have one in their system: Microsoft Paint. Chances are you too have used it once in your life. How about developing one? That has probably been done by a few people and the thought of it could scare beginners. This series of three articles by Budi Kurniawan show us that it is not hard at all with C# and the .NET Framework Base Class Library to build a vector based drawing application. Read on.

FIX: A System.ArgumentException exception occurs when you try to create a Windows form that inherits from a Windows form that contains a dataset

A lot has been already said about extending Windows and Internet Explorer with Band Objects, Browser Bands, Toolbar Bands and Communication Bands. So if you are familiar with COM and ATL you even might have implemented one yourself. Well, in case your were waiting for an easy way to impress your friends with something like Google Toolbar here it is - the .NET way (or should I say Windows Forms and COM Interop way?). In this tutorial I am going to show how to create any of the mentioned above Band Object types with the help of the BandObject control. Later I will also talk about some implementation details of the BandObject.
