Everything ActiveX, from tutorials to software. Unfortunately the demo is for Windows 95 users only, although Win 3.1 and Mac users will be able to view many of the pages--even if you can't use the software (but, hey, the ActiveX SDK has been released for Macintosh, so it won't be long before ActiveX will be available to everyone).
If you're not running Win 95, proceed with the knowledge that some of the graphics won't load properly!
You'll need to use Internet Explorer to run this demo, so if you don't already have it installed, click here.
Once it's installed, or if you're already running Internet Explorer, click here to start the demo. You can also take a look at the README file.
