As usual, there is a download associated with this article, but this time it is multi-dimensional. It contains a Microsoft Access database that should work for you, out of the box, so long as you have Access 2003 installed. If it fails to work for you, then you will need to find and/or install and register the MSSoap30.dll library. We will talk about that later, but it is the only piece a user needs to consume a Web Service from Microsoft Access. For those who want to get into the guts of this thing, I have included the SQL Script for creating the ErrorLog table and the el_InsertErrorLog stored proc (also shown below) and the Dot Net code I used to create my web service.

DoNotExposeGenericLists fires when I publicly expose List via a field, method, property, or parameter. Why? Although Krzysztof briefly touched on this last year, we wanted to expand on this a little through the use of examples. The first reason is that List is designed for speed and for use as an internal implementation detail, whereas Collection is designed for extensibility. Collection provides 4 overridable methods; ClearItems, InsertItem, RemoveItem and SetItem, which allow a derived class to be notified when a collection has been modified. In contrast, List provides none. As an example, let’s say in V1.0 of your framework, you have a Person class that exposes a collection of addresses. You could choose to expose this via a property that returns either a List or Collection : See less

If you've read my recent ASP.NET 2.0 GridView feature article, you know that the GridView control does not require you to refresh the whole page in order to display a new page of records. In fact, the GridView control provides an advanced engine for paging and sorting that is based on ASP.NET script callbacks. The data for the new page downloads behind the scenes, invisible to the user. Once it reaches the client, the data is collected by a JavaScript function and used to update the current view. Paging and sorting callbacks are not 100 percent client-side solutions (if you need a purely client-side implementation, see the one Jeff Prosise built in the Wicked Code column in February 2004). The GridView's page and sort callbacks work on demand, downloading only the data needed; the whole data source is not downloaded onto the client. You still pay the price of a round-trip, but you're guaranteed the most current data even if that data has recently been updated on the server. Having... See less

The preceding code makes an asynchronous call to the backend web server and asks for the resource getnews.aspx?date=09262006. The content of this page is placed at the ‘result’ id location in the resulting HTML page. This is clearly an Ajax call using the XHR object. By analyzing the application in this format, we can identify vulnerable internal URLs, querystrings and POST requests as well. For example, again using the above case, the parameter “date” is vulnerable to an SQL injection attack. continued [ref 1] Ajax security, http://www.securityfocus.com/infocus/1868 [ref 2] XHR Object specification, http://www.w3.org/TR/XMLHttpRequest/ [ref 3] Firebug download, https://addons.mozilla.org/firefox/1843/; Firebug usage, http://www.joehewitt.com/software/firebug/docs.php See less

ASP.NET provides a mechanism to validate user input. That is, before a user submit his/her page, there are several kinds of validators that validate the input. However, in WinForms, we can't get those excellent components. When we validate a text in a control, for example, there is a TextBox named "txtPassword", and it requires users to input a password text beginning with a letter and having 3-8 length numbers or letters, we must register txtPassword's Validating event, and the event method should like: See less

Peter Ritchie - Peter has been working professionally in software development for over 16 years. He's been working with computer software far longer, since his first computer, an Atari 800. Starting in C, Peter progressed to C++ not too long after its adoption by the major compilers. With a strong background in C++, Peter has been writing, designing, and architecting Windows-based software and solutions for over 13 years. Most recently, Peter has gotten involved in the .NET movement, concentrating on C# and making an effort to try and transfer his knowledge to the community—resulting in becoming a C# MVP. Peter is president of Peter Ritchie Inc. Software Consulting Co, where he provides Windows-based software development services in Canada's national capital region. Peter is an active contributor to the MSDN Forums and .NET newsgroups and also an active moderator of MSDN Forums.

Sometimes the examples aimed at demonstrating a given feature or technology have to be simple and canonical; sometimes not. This is one of the cases in which a more realistic example helps to reveal the potential of the underlying framework and determine the best way of using its features. Let's start with a little data access layer built around some of the tables of the SQL Server™ Northwind database. As shown in Figure 1, I created a CoreDataService class with a few methods that are thin wrappers around queries. As you can see, most of the methods return an ADO.NET DataTable object. To build a sample Atlas application, I used the Atlas Visual Studio® 2005 template installed with the latest community technology preview (CTP). Figure 2 shows the markup of the page, not including script. The page contains a couple of dropdown list controls, one for choosing a year and one for selecting the employee name. An HTML button completes the user interface. Note that the button control doesn't... See less
