About the Book
Get expert guidance on how to use the powerful
new functionality of ASP.NET to build dynamic, scalable, Web-based applications.
ASP.NET, the next generation of Active
Server Pages, provides a new programming model based on the Microsoft®
.NET Framework for writing Web applications. Learn about ASP.NET development—with
reusable code samples in languages such as Microsoft Visual Basic®
.NET and Microsoft Visual C#™—in DESIGNING MICROSOFT ASP.NET APPLICATIONS.
This book provides an in-depth look at how to create ASP.NET applications
and how they work under the covers. You’ll learn how to create Web Forms
and reusable components and how to develop XML Web services. You’ll also
learn how to create database-enabled ASP.NET applications that use XML
(Extensible Markup Language) and ADO.NET (a new version of Microsoft ActiveX®
Data Objects). Coverage in this guide includes:
• Managed code and the common language
runtime
• Overview of the .NET Framework and languages
• The ASP.NET development model
• Creating and using Web Forms and controls
• Creating ASP.NET components
• Balancing server vs. client functionality
• Getting and displaying data: XML and
