| A C# Web Spider written as a Web Service |
| C#Today |
| A Web Spider is a program that is used to navigate sites, follow links and collect various information. It is sometimes called a Web Robot. In this article. ST Tan & Aldy Karna discuss the subject, and show how a Web Spider can be written in C#. |

| A Simple wget-clone (WebGet) Using C# |
| The Code Project |
| Well, I guess most of you have used or at least heard of wget which is the linux prog that lets us download files from the internet. You can simply give the following command :- wget http://colorado/files/nish1.zip and the file will be downloaded. Pretty useful huh. You won't have to worry too much about your boss finding out that you are downloading that new mp3 clip instead of finishing that last part of the design which he was supposed to do, but that which he thrust down your throat. |

| Building a Web Service to Provide Real-Time Stock Quotes |
| DotNetJunkies |
| There are many benefits to using a Web Service, including the versatility of the client that consumes the Web Service and the reusability of the code. This article provides an example of a useful Web Service that provides real-time stock quotes through information scraped from public Web sites. |

| Creating an ASPWire News Business Object Part 1 |
| DotNetJunkies |
| This article is part 1 of 2. In this article I will be illustrating how to use members of the System.Net namespace to create a business object that "Gets" all news headlines that ASPWire has available, parses through the return, constructs a DataSet object that holds a DataTable of all news items, and finally returns a DataView that you can bind to. We also make use of Page Caching to limit our request for the data to 3 times per day. We cannot give all the code necessary for you to run this example on you |
|
| Creating an ASPWire News Object Part 2 |
| DotNetJunkies |
| Upon further thought creating a web service based on the ASPWire example in Part 1 of this article would not be that beneficial to sites like ours unless we were ASPWire. I do show the code in this article to create the web service, but it would be easier and more cost efficient to create the business object from part 1 and use that. Besides creating the web service in this article I am going to be demonstrating a better method of caching and reusing the DataSet returned by the business object from part 1. |

| Integrating XML into ASP.Net Web Sites |
| Visual Studio Magazine |
| Much of the talk about XML nowadays tends to focus on using it for data exchange among e-business applications. While it is true that XML is well suited for this purpose because of its ability to describe data and maintain its structure while being transferred among distributed systems, there are many other ways you can use it to enhance applications. I'll demonstrate one of these ways by showing how to integrate XML into a Web site to provide users with news information. |

| Networking Support Provided by the .NET Framework |
| C#Today |
| The .NET Framework provides a wide range of excellent features that developers can take advantage in building networking applications. The System.Net classes are similar to Microsoft's WinInet API (used for internet protocol programming), in that they allow applications to get and send data using Internet protocols. |

| Retrieving Data from Web Services using Standard HTTP 1.1 Compression |
| DotNetJunkies |
| HTTP 1.1 protocol introduced standard ways of compression using gzip or deflate algorithms supported by web servers. Initial tests shown that average compression ratio 10:1 can be easily achieved with large SOAP messages (for instance ADO.NET DataSets with multiple rows). Such reduction of data size cannot be ignored - it's not 10 nor 20 percent but 90% of data size that can be reduced. |

| Scheduled Email Reports |
| ASP Alliance |
| This simple application is designed to be placed into the scheduler of a server to run daily, and to then read from an XML file to determinewhen to send which reports to whom. The chief goal of this application once in place is that no direct server access be required for updates ormaintenance. Reports can be added, removed, or changed, and the recipients and schedule modified as well, all with FTP or FrontPage access only.The application consists of two parts -- the EXE file that must be placed into the Task Scheduler on the server (it doesn't even have to be theweb server where the reports reside, but it should have a persistent internet connection and it must have an SMTP service running on it or elseit needs modified to use an external SMTP server), and the XML configuration file that can reside anywhere as long as the EXE can reference itvia URI. The application can also be run from the command line without an XML configuration file. |

| Using MapQuest Maps in your ASP.NET Application |

| A book is great, but a picture is worth 1,000 words right? So stop giving your address and expecting people to find you ... draw them a map! Better yet, have MapQuest draw a map for you. You'll learn how to add a map to your ASP.NET application in this article. |

| Using SOAP with .NET Web Services |
| ASPFree |
| After creating a .NET web service and testing the methods via the default front-end the framework automatically creates for you when an .asmx page is loaded, it came time to test it via actual code. It was time to send and receive SOAP manually. I considered this an important aspect of understanding and designing web services. To actually see how HTTP handles SOAP and how requests and responses are sent and received. |

| Working with Web Data in C# (Screen Scraping) |
| C#Today |
| Think of the World Wide Web as a giant database management system in which the web sites are the databases and the web pages are the database tables. Now think about how useful it would be to gather data from those tables in a form that could be processed, queried, and combined with other, otherwise unrelated, data in new combinationsusing C# and the .NET framework. In this article, Tony Loton looks at how to: drive HTTP GET and POST requests to web sites using the WebRequest and Stream classes, capture the responses via the WebResponse class, and pick out specific nuggets of information from a web page using regular expressions and the Regex class. The end result is a small but useful engine and a demonstration application, that goes a long way towards allowing data to be selected from web pages as though selecting from relational database tables, using SQL syntax. |

| XML Classes from Web Services |
| XML Magazine |
| Although Web services can be used to return simple types such as integers and strings, I'll focus on how different XML-related classes found in the .Net platform can be returned from Web services to allow consuming clients to integrate the data received into an application using technologies such as XSLT. After introducing a simple example of how the XmlDocument and XmlNode classes can be returned, I'll walk you through a news filter Web service that demonstrates why and when you may want to return these object types from a Web Service. |
