I'm interested to know if Excel can be automatically
opened via a web page having an xla extension and auto run
run its code (as it possible with an xls extension). And
likewise as an inline email (I don't mean attachment).

In XL2000 I can set my security level to Medium or High,
and check the "Trust all installed add-ins and templates".
This way I get workbook macro protection but my useful
addins can run without annoying warnings.

I'm happy to do this on the understanding that it's only
me who can control whether or not to run any addin. But do
I understand correctly?

Thanks
Dan

I'm not sure of all the details but I think that the addin
would have to be open as a spreadsheet and saved as a Web
page. The the addin web page would have to be opened on
the server so that the front end worksheet would have
access to it.

It might be better to have a VB function available rather
than an addin.

Perhaps the experts will know better.

Thank you Peter for replying and your comments,

Since I first posted I now realize that the
checking "Trust all installed add-ins and templates" means
exactly what it says, ie those I have already installed
myself. So in once sense the basis of my original question
does not apply. However ...

If I double click file *.xla it will open Excel with a
blank page (if security level allows) and possibly run
code. I'm probably being a bit paranoid but to put my
mind at rest I'd like to know that similar cannot be done
via html!

Thanks,
Dan
