Building Microsoft ASP.NET Applications for Mobile Devices, 2/e
暫譯: 為行動裝置建置 Microsoft ASP.NET 應用程式，第2版

Summary

A comprehensive reference for developing mobile Web applications with ASP.NET Mobile Controls, which ships with Visual Studio .NET 2003

This update of a popular Microsoft Press® title shows programmers how to use the Microsoft .NET Framework, ASP.NET, and Microsoft Visual Studio® .NET 2003 to create powerful, next-generation applications that are available anywhere, on phones, Pocket PCs, and other mobile devices. With this title, programmers learn how to incorporate dynamic access to data with ADO.NET, plus how to deliver content from a single ASP.NET page to multiple client browsers on devices with limited display and input capabilities.
