Synopsis

Microsoft's Active Server Pages (ASP) technology has become wildly popular with web developers. However, the techniques for developing custom ASP components, not to mention the inevitable snags and pitfalls, are not well documented. What's more, the successful ASP component developer must be a jack-of-all-trades, with some knowledge of COM and COM+, threading models, and the ASP object model, as well as a mastery of one or more language tools and development environments.That's where Developing ASP Components, 2nd Edition, comes in. Its first section explores the topics everyone needs to know to develop effective ASP components:

• Configuring the ASP development environment.
• ASP components and the Component Object Model (COM).
• ASP components and threading models.
• ASP components and Component Services, which provide a variety of services to ASP components.
• The objects, properties, methods, and events available in the ASP object model.

ASP components are language independent, and developers increasingly tend to use more than a single language tool. Thus the remainder of the book focuses on ASP component development using one of two major development tools--Microsoft Visual Basic and Microsoft Visual C++ (with the ActiveX Template Library)--along with a number of other languages, such as Perl and Delphi. Each section focuses on the issues that concern the ASP component developer using that particular development environment. These issues include:

• Accessing ASP's intrinsic objects.
• Accessing data using ADO.
• Creating n-tier web applications with VB.
• Handling persistence using MFC along with Visual C++/ATL.

It's this strong focus on two major development environments, along with a thorough grounding in essential ASP topics, that makesDeveloping ASP Components the definitive resource for the ASP application and component developer.

About this title

Review:

Aimed at more experienced VB or C++ developers, Developing ASP Components, Second Edition gives plenty of advanced advice for creating and using COM-based components, which are a must for serious scalability and performance on the Microsoft Web platform.

This book excels at showing the inner workings and issues involved in designing custom COM-based components in VB, ATL, and/or MFC, as well as tapping the built-in components that come standard with COM, including transactions, mail objects (with CDO), and database programming (with ADO). In particular, for the C++/ATL/MFC developer, practical sources of information (and sample code) are in short supply, and for this readership, the book fills a particularly worthwhile niche. Much of it uses VB in examples for designing effective, high-performance components.

Several early sections look at the details of COM-based components (including the notoriously difficult threading models, along with similar details). The author does a good job of explaining this challenging topic. The practical examples of using built-in COM objects and services on the Windows platform really make this book a winner. The sample code and hints for tapping such COM-based standards as transactions, Active Directory, message queueing, CDO, and ADO are very helpful. Better yet, the book covers the same ground for C++ programmers using ATL (and MFC) to create the most lightweight (and potentially the fastest) Web components available today.

Until the new .NET Framework arrives later in 2001, COM (and COM+) is still the best way to build and share components for use with ASP in Windows. Developing ASP Components shows you how to build components that are fully integrated into the Microsoft Web platform. Whether you build custom components, or just want to use services in VB/C++ code that are available to your Web applications, this title will clue you into getting the most out of your components. It's a source of expert information that you won't likely find anywhere else. --Richard Dragan
