The LA Fox Developer Newsletter

November 2000

Boot Camp (Con’t from page 1)

If time permits, wrap up with how to build a complete Visual

FoxPro application.

Full speaker notes and several very useful Visual FoxPro base

classes will be distributed to all attendees.

Accelerated Internet session from the basics of Visual

FoxPro to the advanced topics of ASP and COM objects

This session is geared toward programmers with a working

knowledge of FoxPro 2.6 and/or Visual FoxPro. It will cover

basics, object oriented programming, using Visual FoxPro as

the database part of a web server, Active Server Pages (ASP)

and COM objects.

The following topics will be discussed:

Using Web forms and techniques in Visual FoxPro Win-

dows applications

Using Visual FoxPro on your web server: Tips, tricks,

techniques, ASP, and COM

Visually defined objects

Objects defined in code

Generating an HTML Page from Visual FoxPro

HTML transfers from FrontPage to Visual FoxPro

Assign/Access methods

Creating COM objects

Using COM objects in ASP pages

Questions will be entertained throughout the day. Handouts will

include how to setup Visual FoxPro on your web server, working

code examples, and more.

The Programmable Web: Web

Services Provides Building

Blocks for the

Microsoft .NET Framework

By Mary Kirtland

fSUMMARY: Web Services are building blocks for constructing

distributed Web-based applications in a platform, object model,

and multilanguage manner. Web Services are based on open

Internet standards, such as HTTP and XML, and form the basis

of Microsoft’s vision of the programmable Web. This article

defines Web Services and the key enabling technologies that

ensure services can be aggregated into applications. It then

describes Microsoft’s new Micmsoft .NET Framework and its

support for creating and consuming Web Services. ]

One of today’s most pressing challenges is application integra-

tion: taking different applications running on different operating

systems built with different object models using different

programming languages and turning them into easy-to-use Web

applications. The Microsoft vision of Web Services, based on

open Web standards such as HTTP and XML, addresses this

challenge.

But supporting standard protocols isn’t enough. There must be

some way to create, deploy, scale, and maintain these Web

Services. This is where the Microsoft® .NET Framework comes

in.

This article describes Web Services and the components of the

Microsoft .NET Framework, including the common language

runtime, the services framework, and the programming models

for building and integrating Web Services.

A Look at Web Services

Broadly speaking, a Web Service is simply an application

delivered as a service that can be integrated with other Web

Services using Internet standards. In other words, it’s a URL-

addressable resource that programmatically returns information

to clients who want to use it. One important feature of Web

Services is that clients don’t need to know how a service is

implemented. In this section, I’ll explain how Web Services

combine the best aspects of component-based technologies

and the Web, and introduce the infrastructure needed to com-

municate with Web Services.

Like components, Web Services represent black-box functional-

ity that can be reused without worrying about how the service is

implemented. Web Services provide well-defined interfaces,

called contracts, that describe the services provided. Developers

can assemble applications using a combination of remote

services, local services, and custom code. For example, a
