| ADO .NET for the ADO Programmer |
| MSDN |
| ADO .NET is the latest in a long line of database access technologies that began with the Open Database Connectivity (ODBC) application programming interface (API) several years ago. Along the way, a number of interesting things happened. For example, COM landed at the database territory and started a colonization process that culminated with OLE DB. Next, ActiveX® Data Objects (ADO)—roughly an automation version of OLE DB—has been elected to govern the Visual Basic® and ASP community of Windows®-based database developers. |

| Advanced DataGridding: Paging, Sorting, Showing Grid Statistics and Hiding Redundant Controls |
| DotNetJunkies |
| This article takes a look at how to solve some of the most common problems developers encounter when trying to work with the DataGrid. These include DataGrid paging, sorting by columns, showing statistics about result, hiding the pager button and hiding the DataGrid itself when there are no results to display. This article walks you through a solution. |

| Allowing Users to Upload Multiple Files at Once |
| DotNetJunkies |
| This article demonstrates how to allow users to upload multiple files from thier computer (the client) to your server. Specifically, this article will demonstrate how to set up a page that has 5 HtmlInputFile controls where a user can choose 5 images to upload. Only .jpg and .gif extensions will be accepted on the server and each one will be saved to a different directory::so any image that has the extension .jpg will be saved to the jpgs direcory and .gif will be saved to the gifs directory and everything else isn't saved at all. |

| An Event to Remember |
| MSDN |
| Last month, we talked about performance and boxing. One of the questions that came up from a reader was why the Perl version is so much faster than the C# version. One answer is that Perl is very good at what it does. One reader pointed out that I had forgotten to tell the Regex to compile the regular expression rather than interpret it on every match. In Beta 1, this is done by passing "c" as the second parameter to the Regex constructor (there's an enum to do the same thing in Beta 2). This cuts the overhead nearly in half, and reduces the elapsed time for the fastest version down to a little less than 7 seconds. |

| An Exception to the Rule, Part 2 |
| MSDN |
| In the previous column, we briefly mentioned Application_Error events and Page_Error events. These events are raised whenever we have an unhandled exception occur within our application. If a Page_Error event is present within an ASP .NET page, and an unhandled error occurs, the event is raised. Application_Error is slightly different. It is raised for all unhandled exceptions in our ASP .NET application and is implemented in global.asax or within an HTTP Module. |

| An Extensive Examination of the DataGrid Web Control: Part 1 |
| ASP.NET - 4GuysFromRolla |
| This article is the first in a multi-part series on using the DataGrid Web control that will span several weeks. The ASP.NET DataGrid Web control, which displays database information in an HTML table, is highly versitile. In its simplest form (examined in this article) the DataGrid displays a bare-bones HTML table, but it can be enhanced to output a richer UI, to allow for sorting based on the database columns, and to even allow paging of the database results! All of these interesting topics will be covered in future parts of this article series. |

| An Extensive Examination of the DataGrid Web Control: Part 3 |
| ASP.NET - 4GuysFromRolla |
| This article is the third piece of a multi-part series on using the DataGrid Web control that will span several weeks. The ASP.NET DataGrid Web control, which displays database information in an HTML table, is highly versatile. The basics of the DataGrid were discussed in Part 1; information on specifying display properties of the DataGrid was discussed in Part 2. This article will examine how to associate custom events with the DataGrid. |

| An Introduction to Mobile Programming in C# |
| C#Today |
| With the expansion of the web away from traditional browsers, current technology has brought the internet into mobile devices. Microsoft has constantly improved its support to such devices, and the introduction of the .NET framework has taken this support a step further. With .NET we can program for a mobile device as a normal web page and the Common Language Runtime and .NET framework will take care of rendering the data in the appropriate format, i.e. as HTML for browsers, as WML for mobile phones, etc. In this article Niranjan Kumar introduces us to programming for Mobile devices using C# and ASP.NET pages. This is illustrated with a Stock List application that accesses a SQL Server database and lists available stocks on either a Mobile device or HTML browser. |

| An Introductory Guide to Building and Deploying More Secure Sites with ASP.NET and IIS, Part 2 |
| MSDN |
| Forms authentication is one of the most compelling and useful new features of ASP.NET. It enables developers to declaratively specify which files on their site can be accessed and by whom, and allows identification of a login page. When an unauthenticated user attempts to retrieve a page protected by forms authentication, ASP.NET automatically redirects them to the login page and asks them to identify themselves. Included here is an overview of forms authentication and what you need to know to put it to work. Also included is hard-to-find information on the security of cookie authentication and on combining forms authentication with role-based URL authorizations. |

| An Overview Of Link Label In C# |
| C# Help |
| 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. |
