I don't know of any tutorial on OLE-Browser. I would summarize what I know about it as follows:
You start it by opening the file C:\Perl\html\OLE-Browser\Browser.html in MS IE (it won't work in other browsers, AFAIK).
If you click on IE menu option 'Allow blocked content', the browser will scan the Windows Registry and show you a list of Type Libraries, so you can browse the Interfaces and their methods and properties.
How would you use this information? Well, this is a MS COM/Automation question, not a perl question.
