| .NET Anatomy - ADO.NET in Beta2 : Part 1 |
| DotNetJunkies |
| This article reviews the ADO.NET object model found in Microsoft’s .NET Framework Beta2. The information presented here will be useful both to programmers who worked with Beta1 and also, to those just starting with the framework. |
|
| .NET Anatomy - ADO.NET in Beta2 : Part 2 |
| DotNetJunkies |
| In my last article I reviewed the ADO.NET object model as it is presented in the .NET framework Beta2. To put this information to practical use, this article will provide a walkthrough of how to use Microsoft's newest set of developer tools, found in Visual Studio.NET to create a working Web Application that accesses an SQL database. |

| .NET Anatomy - Data Concurrency in ADO.NET, Part II |
| DotNetJunkies |
| This is the second article in a series covering the subject of Concurrency in ADO .NET. Concurrency is the method by which many users are able access and change the same data simultaneously without being concerned that they are overwriting each others work. |

| .NET Anatomy - Data Concurrency in ADO.NET, Part II |
| DotNetJunkies |
| This is the second article in a series covering the subject of Concurrency in ADO .NET. Concurrency is the method by which many users are able access and change the same data simultaneously without being concerned that they are overwriting each others work. The architects of the .NET Framework made a design decision that the DataSet object assumes that Optimistic Concurrency as the default method of concurrency. |
|
| .NET Anatomy - Data Concurrency in ADO.NET, Part III |
| DotNetJunkies |
| In the two previous articles on this subject we have looked at how the ADO.NET DataSet object contains built-in support for concurrency operations. This functionality helps the developer to build applications that keep users from overwriting each other’s data accidentally. The implementation is open and flexible and so what I will be showing you here can be tailored to your own requirements |

| .NET Remoting ( A Simple Approach) |
| C# Help |
| .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. |
|
| .NET Remoting - The Interface Approach |
| C# Help |
| 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. |

| A Remedy for DataGrid Vertigo |
| DotNetJunkies |
| The AlternatingItemStyle can be a wonderful thing. But in many cases I found that I would start to get
a feeling like vertigo if I scrolled the page up or down. So I thought back to my days in Manhattan in the financial
industry and remembered how I used to prepare reports to be viewed on screen. I alternated the
colors of the rows, but I did it every three or five rows (depending on the width of the report,
the content of the report, or my own aesthetic taste). |

| A Reusable, Flexible Error Reporting Framework |
| The Code Project |
| Using configuration classes and simple implementation, this library allows your applications a flexible method of reporting errors that happen. Included is a Windows XP-like WinForms UI that allows users the ability of opting for error reporting in WinForms applications. |

| Abstracting ADO .NET |
| MSDN |
| With the release of Microsoft® .NET just around the corner, developers are gearing up to take advantage ot the many features, increased interoperability, and better data integration that the new framework promotes. While COM and Visual Basic® 6.0 are still widely used and will likely live on for years to come, I've met many developers who are anxious to get moving with the .NET components. Some of the questions I am asked most often regarding .NET are how developing with ActiveX Data Objects (ADO) 2.x will change under ADO .NET and how can you still abstract ADO into a data service component. So, in this month's Data Points column, I'll try to tackle these issues.

| Accessing Data From SQL Server |
| C# Help |
| Among the many things that are changing with .NET is data access. Under the .NET Framework, data access is handled by a set of classes called ADO.NET which are essentially an augmentation of the existing ActiveX Data Objects (ADO). |

| Accessing Web Services from Windows Client |
| C#Today |
| Over the last several years, we have seen the Internet evolve from delivering static and simple HTML pages, into using dynamic, programmable and reusable web components. Microsoft's .NET framework introduces Web Services and SOAP that take the Internet a step further, by allowing the web applications to be more distributable, reusable and resourceful. In this article, Ravi Venkatarajalu look at how to combine the features of Web Services, SOAP and the .NET framework with Microsoft Excel 2000. We will also see how to serialize a Dataset and send it as part of a HTTP Request to a Web Service. |

| Adding a "Totals" Field in a DataGrid |
| DotNetJunkies |
| Lately one of the questions that has been popping up a lot is, "How do I show column totals in a DataGrid?" Personally I have provided sample code for this question more than a few times, so I thought it would only be appropriate that we here at DotNetJunkies HQ get a tutorial up on the topic. |

| Adding a Blank Row to a DataGrid (Used to INSERT rather than UPDATE) |
| DotNetJunkies |
| In this article we will be illustrating one way to add a blank row to a DataGrid. Why would you want to do this? Who knows, maybe to enable a user to add a new record. This article will show you how to add a new row to a DataGrid by manipulating its DataSource - in this example a DataTable. Note that we will be simulating saving the new item back to the
database. |

| Adding a Default ListItem in a Databound Listbox in ASP.NET |
| 4Guys from Rolla |
| In a previous article I showed how to use databinding to automagically populate an ASP.NET's listbox Web control with just a few lines of code. (If you've not already read the past article, be sure to do so now.) I've received a couple of feedback emails from folks since publishing the article asking how to add a default option to the listbox. That is, they want to add a listitem to the listbox, like: -- Please Choose an Option Below--. In this brief article we'll tackle this topic and more!
