1. I'm not that familiar with the WMI api. you'll have to do some
research on this yourself ...
2. You're right about that, you can use a HTA file to show your
webpage. A HTA is a more trusted version of IE and will allow you to
create ActiveXObjects without the security restrictions of IE. If you
have AntiVirus software installed it may alert the user if you try to
access the filesystem or any other potential harmfull behaviour.
3. I've automated Excel from Jscript and it works fine. I'm not sure if
you can open an excel file inside an iframe with COM. It may be
possible, you'll have to check the reference at MSDN :

Another way is to create the excel file with COM or define it in XML
and then open it in the iframe.
