Web Services is a programmable entity that provides a particular element of functionality, such as application logic. Web Services is accessible to any number of potentially disparate systems through the use of Internet standards, such as XML and HTTP. Applications built with ASP.NET Web Services can be either stand-alone applications or subcomponents of a larger web application and can provide application components to any number of distributed systems using XML-based messaging. RAD Studio provides a number of methods that can help you build, deploy, and use applications with ASP.NET Web Services. For more general information about Web Services, refer to the Microsoft .NET SDK Documentation.

Web Services is an Internet-based integration methodology that enables applications, independent of any platform or language, to connect and exchange information. Web Services is tightly integrated with the ASP.NET model used for the .NET Framework. Unlike traditional native Windows applications, ASP.NET Web Services applications contain objects and methods that are exposed over the Web using simple messaging protocol stacks. Any client can invoke a Web Services application over HTTP using a WebMethod. Like any method that can be accessed by way of a simple Windows Form application, a WebMethod provides some defined functionality. Unlike other types of methods, however, the... more | |

Understanding the Web Services infrastructure requires that you have some exposure to Extensible Markup Language (XML), Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL), and Universal Description, Discovery, and Integration (UDDI). Because the infrastructure already exists, as a developer of XML web services, you can leverage the existing technology by using standard Web protocols such as XML and HTTP. CodeGear provides an easy way to create, deploy, and use web services without concern for back-end processing so you can focus more on designing your services. This topic provides the conceptual background to understand how the protocol stack contributes... more | |

ASP.NET Web Services support VCL.NET Forms and ASP.NET Web Forms. These forms can be used to create client applications that access Web Services applications. Use the Add Web Reference feature to add the desired ASP.NET Web Services application to the client application. Using the UDDI Browser you can locate Web Services applications you might want to use. RAD Studio provides simple tools to develop and deploy your ASP.NET Web Services applications. Additionally, RAD Studio helps you import WSDL documents that describe particular Web Services applications and expose their functionality to the client application. You can use the sample WebMethod provided... more |
