SAN FRANCISCO - Microsoft is upgrading its application development tool set to
get as many programmers as possible building Windows 2000 applications - a
savvy move since that well is basically dry.
The company this week announced that it is reworking its Visual Studio tool
set to focus on building Web-enabled applications, along with applications
that are Windows-2000 specific. Visual Studio 7.0 is slated to ship by
year-end but a new tool kit is expected in March, according to a Microsoft
Version 7.0 of Visual Studio, which is an umbrella that encompasses
Microsoft's Visual C++, Visual Basic and other tools, is being designed to
include utilities for Web-based forms and services, along with offering XML
and HTTP-based services. But industry watchers say the changes to Visual Basic
are creating the real buzz in the developer community.
"There have been features reserved for Visual C++ since the dawn of the VB
world,'' says Dan Mezick, president of New Technology Solutions, a North
Haven, Conn. VB consultant and training company. "Now Microsoft is putting
those features into VB... That's Microsoft trying to leverage the huge base of
VB developers and get them writing applications for Windows 2000.''
Microsoft contends there are 3.4 million VB developers but several analyst
firms put that number anywhere from 1.5 million to 2.5 million. There's
generally believed to be about 300,000 to 500,000 VC++ developers.
The object-oriented features that are being dropped into VB include:
Inheritance, which is like a digital family tree, where features are
automatically passed down to new objects. It is virtually the opposite of
aggregation, which has been a VB mainstay.
Free threading, which means that more than one process can use the same
application at the same time.
Polymorphism, geared to increase code reuse, which allows the same piece of
code to be used in different ways.
Analysts say these kinds of tool features are what will help developers write
applications for Windows 2000, a complicated operating system with a slew of
new features, like Active Directory and Intellimirror. Windows 2000 has
anywhere from 30 million to 45 million lines of code. Windows NT 4.0, its
predecessor, has about 15 million lines of code.
And Microsoft is hoping that more developers will mean more Windows 2000
applications. As of this week, there are 27 certified applications for the new
Laura Didio, an analyst for Giga Information Group, however, says it will take
more than beefed up tools to get developers building programs for the
complicated new operating system.
"We are talking about really complicated programs,'' Didio says. "It's a much
larger code base and there's lots of add-ons and wizards. It's a whole new
environment. You just don't hand people tools and say, go to it. They need
design guides and how-to's and do's and don'ts if they're going to get any
level of quality." she says.
"That's what I'm watching for,'' Didio says.
