Developing ASP Components 2nd Edition
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 makes
Developing ASP Components the definitive resource for the
ASP application and component developer.
