Creating a Web Application
Wecome to a new DHTML Lab thread: Creating a Web Application.
All the techniques discussed arise out of my work at Meteor Inc. Yes, I do have a day job, and a very demanding one. For the last year, we have been preparing a major Web-based application, due for release spring of 2000.
Our product will be much talked about, not only for its prototype functionality, but also for its "look." It is a true Web Application. It is not a Web page or site. It is software. And it has been built with DHTML.
My associate, Giorgio Braga, a DHTML pioneer and co-founder of Meteor, has developed the Navigator version of our product. A true eye-popping piece of work, constantly soliciting comments on the line of "I didn't know you could do that. Do the Netscape people know?" English may be his second language, but DHTML is his first. To me fell the challenge of creating the Explorer version. We have taken the browsers to their limits, believe me.
So, some of the routines Giorgio and I have used will find their way into the pages of DHTML Lab, albeit the simpler ones. Sometimes, they will be full columns, other times DHTML Diner articles. They will, of course, be stand-alone entries, but they will have a common theme: making your Web page look and function like an OS application.
Special thanks to our intrepid leader at Meteor, Bill Barhydt, and my tireless WebReference editor, Andy King, for allowing me to miss deadlines to finish work the other was clamoring for.

Identifying Installed Fonts
Be kind to your server, load pages faster for the user and give your Web applications a sleeker, more professional look. Use dingbat fonts already installed on user systems in place of downloaded images. In this tutorial, we use DHTML to identify installed fonts, with a single function. Your users will thank you.
DHTML Application Toolbars
Using the techniques discussed in Column 24, we build application-like toolbars for Internet Explorer. Both text-only and more complex text-image toolbars with keyboard access are discussed.

Accessing the User-Defined System Colors, Part I
The first step in the creation of web pages, that look and act like OS applications, is the correct use of the user-defined system colors. We'll look at how each of these colors is set by the user, what effect they have on browser rendering, and how they are reflected into Explorer DHTML. Then we'll create draggable OS-like popup dialogs, complete with active and inactive colored titlebars, that adapt to any color scheme the user has chosen.
